Executive Summary
Harlan Laboratories is a leading provider of essential, pre-clinical and non-clinical contract research,research models, lab animal diets, and services to the pharmaceutical, biotech, medical device,
agrochemical, and chemical industries and other research organisations.
Harlan Labs provide customers with products and services to optimize the discovery and safety of new
medicines and compounds.
The client had requested us to undertake a Building Energy and Sustainability Feasibility Assessment for
Harlan UK, Wyton, Huntingdon, Cambridgeshire. This is in response to reducing the energy consumption
of the facility in recognition of increased policy compliance legislation, operational cost optimisation and a
continuing business driver to deliver improved building operational performance.
Taking into account the design and age of the building and plant deployed the inspection has identified
significant opportunities of improving HVAC system performance. These include improved maintenance
schedules, optimising the operation of HVAC plant, control strategy optimisation and implementation of
improved building systems energy and process operational metering, monitoring and targeting.
Cognisance should be made of European revised legislation to future proof the facilities.
During inspection it was observed that the site does not currently meet the Government and Industry
stipulated Guidelines in some areas. The Wyton site (Beagles) does not have any form of cooling which
would be needed to meet maximum temperature requirements. Based on the site visit, there are
operational problems with the heating only AHUs due to the age of the plant. Based on the Home Office
(HO) Code of Practice for the housing and care of animals in designated breeding and supplyingestablishments, and HO Animals (scientific procedures) Act 1986 Pg 31 requires some form of cooling to
be provided in order to attain temperatures between 15-24 Deg C for beagles to deal with extremes of
temperature.
It was also noted that the site lacks an air filtration philosophy, On Site a minimum of F7 filtration is
generally recommended to ensure operator safety, studies conducted in the US by the Environmental
Epidemiology Program, Department of Environmental Health provide direct correlation between PM2.5
particles and increased incidence of cancer and respiratory ailments. (The Concentration-Response
Relation between PM2.5 and Daily Deaths by Joel Schwartz et al) carried out over six U.S. cities. There
may also be a risk to the product as a result of poor air filtration.
As the site is an animal research facility, we would expect that protection of pure breeds from
contamination and outside pollutants is a primary goal. We would highly recommend that a filtration
philosophy be developed at site, as the site may be susceptible to airborne viruses from the nearby
testing facility within site which could wipe out existing stocks and poses a business continuity risk.
Due consideration should be made to comply with European regulations when Directive 2010/63/EU will
take full effect from 1 January 2013, these regulations prescribe the temperature, relative humidity, space

ventilation, lighting, and noise levels within these spaces, which require a provisional 1520 ACPH.
Stocking densities should be taken into account when selecting air change rates.
The survey covered the Inspection of HVAC systems, assessing the performance of fans, and associatedheating and cooling electrical/gas loads, in order compare performance with industry standards and to
identify energy savings whilst maintaining their minimum performance requirements. A key observation
was the lack of effective controls at site; it would appear that only Building 3 is connected on the BMS
with out of range alarms with the outstation located at Hillcrest. Operational problems are being logged
by the site personnel with no means of viewing control parameters at site, it is highly recommended that
the site incorporate a BMS outstation with all plant operations on a BMS outstation to have effective
control of critical monitoring parameters to ensure HO compliance for recording temperature and
humidity.
While reviewing the onsite records, there were no Operational and Maintenance manuals, Commissioning
Data for the Mechanical plant including commissioning results ( including flow rates) for the AHUs werenot found with the O&M Manuals. The As Built record drawings and subsequent amendments were not
available at site. Planned Preventative Maintenance Records indicating the frequency of maintenance /
schedules and building log book were not made available during the visit.
We would recommend that the site carry out a re-commissioning exercise in order to validate air flow
rates in order to check for compliance with HO regulation.
The site currently has 5KW cooling capacity to the Archives room, which does not warrant an Air
conditioning inspection.
In summary the existing HVAC system chilled water operation at Harlan UK, Wyton, Huntingdon,Cambridgeshire would benefit from optimisation to enable ongoing operational efficiencies to be realised.
Replacement of AHUs in 1,2a,2b,4,5,11,12,24,25,25a,26,27,28 which have a heating only AHU should be
considered as soon as possible to ensure Regulatory compliance and plant security.
Buildings 16,17,18,19,20,21 housing whelping do not have an AHU, but rely on a rudimentary wall
mounted supply and extract fan with a local gas fired heater in the space coupled with infra red localised
heating in the cages to provide a temperature of 26-28 Deg C to comply with Home office regulations. It is
not clear whether adequate air changes and temperatures needed are being attained. It is recommended
that these areas be reviewed for compliance.
Electrical supplies to the site is via 2 Nos feeds, the top side (Admin areas, Buildings 1,2a,2b,3) andbottom side (4,5,11,12,16,17,18,19,20,21,24,25,25a,26,27,28). The top side is served via a 400A main
breaker whereas the back side is served via a 200A main breaker. The site also has a backup generator
provision, the top side being served via a 100KVA generator, while the bottom side served via a 200KVA
generator.
It would appear that the generator serving the top side is clearly undersized for its duty and requires an
upgrade, while the bottom side generator appears to currently meet the loadings. We would recommend

a full electrical audit to review the existing electrical infrastructure at site with a view to incorporate
additional cooling loads going forward.
A separate lighting study will follow this report.

It was noted that the site has a negative image/ perception within the local community, there
exists an opportunity to redress this image. We have identified a solution which could result in
the site becoming a carbon neutral flagship site while also addressing local community
cohesion and good local Public Relations.
As the site is situated in a rural area surrounded by farmland with an opportunity to use local
crop waste as fuel for heating / cooling and electricity generation, thereby helping the local
community / farmers and improving community cohesion. There are government incentives in
the form of ROCs (Renewable Obligation Certificates) for such projects.
While this option is by far more expensive than others investigated, we believe this would
help the site reduce the negative press / publicity it has attracted over sometime while
helping to reduce energy consumption and result in becoming a carbon neutral site.
An option to explore would be to set up an ESCO (Energy Supply Company) for the sites entire
energy needs, there are ESCOs who would set up the plant providing the necessary
infrastructure and capital funding for long term energy contracts.
The client would benefit from savings on capital outlays and expenditure while benefitting
from a carbon neutral operation, should local bio-mass and wood chip be sought, this would
help improve the local community and improve the clients image within the community.
We believe this represents a great opportunity for the client to reduce the negative image
within the local community while upgrading to a carbon neutral flagship operation.
We shall be happy to explore this in detail and provide budget costs should the client wish to
progress this further.

2.0 Introduction and General Systems Overview
Harlan UK, Wyton, Huntingdon, Cambridgeshire PE28 2DX consists of several buildings in the campus. Thevarious blocks house the stock, brood and whelping along with an Office and Administration area. Each of
the Blocks is generally self contained with an AHU, DHW provision with an oil tank / LPG connection. The
site also houses Churchill Labs, a private research facility, access was not available to review that building
an assessment has not been included in our report.
Incoming services
The incoming water services to site is via a single metered supply within the site premises with 6 Nos
water manholes provided for its distribution. During the survey, we could not find a water treatmentfacility, we would assume that the water used for cage washing and consumption is the towns mains
water.

Electrical supplies to the site is via 2 Nos feeds, the top side (Admin areas, Buildings 1,2a,2b,3) and
bottom side (4,5,11,12,16,17,18,19,20,21,24,25,25a,26,27,28). The top side is served via a 400A main
breaker whereas the back side is served via a 200A main breaker. The site also has a backup generator
provision, the top side being served via a 100KVA generator, while the bottom side served via a 200KVAgenerator.
It would appear that the generator serving the top side is clearly undersized for its duty and requires an
upgrade, while the bottom side generator appears to currently meet the loadings.
The site is served by a number of Distribution boards located in the various buildings, some of the boards
appear to be dated, it is recommended that a periodic inspection report of the electrical installation be
carried out to achieve regulatory compliance.
We would recommend that the site carry out a full electrical audit in order to review the electrical
infrastructure at site.
There is no gas supply in the area, the heating for the entire site is met via gasoil fired / LPG boilers
located all around the site.
The site is not connected to the mains sewer and operates a sewer /effluent treatment plant for soil
waste.

LPG Layout
The site has an extensive network of LPG tanks and piping at site providing heating for the buildings,
domestic hot water requirement is met via localised point of use water heaters.
Offices and Admin Block
The office areas are heated via 2 Nos oil fired boilers located within the building. DHW for the offices is
provided via point of use electric heaters. There is generally no cooling at site, cooling is only being

provided to the archive room via a 5KW heat pump. The office and admin block heating is fed of a 2500
Litre oil tank located in the courtyard. The oil tank is currently being supported on bricks, not consistent
with DEFRA regulations which prescribe a proper foundation.
Buildings 1,2a,2b,4,5,11,12,24,25,25a,26,27,28
Buildings 1,2a,2b,4,5,11,12,24,25,25a,26,27,28 house the brood, and stock. These buildings are served
via a primary Air Handling Unit (AHUs), these are constant volume systems providing fresh tempered air
to the barriers. The Primary AHUs are aonce through type units with the extract air from the building
vented through openable louvers. There is no HVAC control optimisation strategy e.g. Night setback,booster facility, and or free cooling on the AHU.
The AHUs for these buildings are fairly basic, with air being heated by gasoil / LPG fired heaters. The
centrifugal fan is housed within an enclosure, and connected to air socks which serve the barriers. It
would appear that these AHUs do not have adequate level of filtration, a minimum of F7 is required for

air socks. It is important to have the extract air ducted as it could provide a possible path for
contamination of the pure stock by airborne viruses.
We would recommend that air quality / filtration be reviewed in order to comply with the European
RegulationsDirective 2010/63/EU will take full effect from 1 January 2013.
Buildings 3, 29
Building 3 houses the Whelping puppies, the building AHU is served via 2 Nos modern AHUs. The air
handling unit is made up of a supply and return air sections, this consists of an inlet louvre, a panel filter,
Gas fired heater and a forward curve belt driven centrifugal fan driven by a 415V 3 phase motor.
The AHU incorporates a recuperator before the air is discharged into the atmosphere. Air is extracted
from the conditioned space via a centrifugal fan, driven by a 415V 3 phase motor. The AHUs are on an
inverter. Heating for the Building 3 is provided via Gas fired heater batteries located in the AHU. Both the
AHUs were running at 31 Hz during the survey. AHU-1 had control issues with temperature control
ranging from 17-27 Deg C, while AHU-2 was performing satisfactorily within a deadband of 2 Deg C.
The air-handling units operate under the control of a BMS system, which is located at Hillcrest.
The AHU is interfaced with the fire alarm, in case of a fire, the Supply fan is shut down, and the extract fan
is also shut down. The fire philosophy of the building is not well defined. The HVAC plant for the barriers is
being operated continuously.
Building 29 is served via 2 Nos modern AHUs, this building was being constructed during the survey; no
details of the AHUs were available for review.

Buildings 16,17,18,19,20,21
Buildings 16,17,18,19,20,21 houses the Whelping puppies, ventilation for these buildings is provided via
rudimentary supply and extract wall mounted fans coupled with a gas fired heater located within thebuildings along with localised infra-red heaters in the cages. Home Office regulation for puppies requires a
local environmental temperature of 26-28 Deg C for at least the first 5-10 days of life. It is not clear how
these parameters are being recorded / monitored at site.
AHUs for buildings apart from Building 3 and 29, do not have an extract ductwork but rely on gravity
louvres for extract, this has resulted in increased gas energy consumption at site
Asbestos roofing
It would appear that Buildings 11,12,16,17,18,19,20,21,22,23,24,25,25a,26,27,28 have asbestos roofing, it
would appear that the roofing due to age has become extremely fragile. Consideration should be made toupgrade the roofing to improve energy performance of the building.
Building Fabric
Harlan Labs, Wyton was constructed in the 1980s; the thermal elements and standards reflect the
building regulations level of compliance at the time of construction in 1980. This building has not
undergone any significant re-development works over the years and the services match the age of the
building. The car park was later added to the main building.
The construction of Harlan Labs, Wyton is based on a concrete frame and floors with block cladding walls
with corrugated insulated panel roofing. The windows are generally double glazed with Aluminium frames
which are part of the original installation.
Building Fabric for Buildings 1,2,2a,3,4,5 appears to be sound, we would recommend that an air
permeability test be carried out in order to determine their air tightness. Buildings
11,12,16,17,18,19,20,21,22,23,24,25,25a,26,27,28 have a poor building fabric which appears to be in
excess of 30 years old, consideration should be made to upgrade the building fabric to improve the air
tightness and hence energy performance of the buildings.
Site Energy Consumption data
Actual electricity consumption during 2011 was 359,055 kWhs costing 44,881.87 based on an electricity
tariff of 12.65 pence/kWh (Inclusive of VAT at 17.5%), the site uses Gasoil Class A2 32 Sec1 as a heating
medium along with LPG, unfortunately there is no consumption data available to carry out an energy
benchmarking.
Projected energy savings and costs are based on 2011 energy prices.

3.0 Energy Performance Benchmarks
The building consumes significant amounts of gasoil, LPG and electricity for its operation to provide forheating, ventilation, lighting, small power and DHWS services.
The table below relates to the energy consumption of the building, unfortunately treated floor area of
each building including total production areas are currently unavailable for carrying out an energy
performance benchmarking assessment. Electrical Costs below are based on 12.65p / KWHr for Electricity.
While this data is generally accurate to an extent, we would recommend an AMR (Automatic Meter reading)
for the Gasoil meter, so as to enable a more accurate degree day regression analysis be carried out for the
site.
LPG is used for heating the barrier / production areas, while gasoil is limited to the Office / Admin block andused as generator fuel.

Regression Analysis
The degree day plot allows us with a comparison with weather related measure and is a powerful tool for
energy managers to evaluate the performance of buildings. This shows the relationship between the
actual external temperatures and the electrical consumption on site.
Based on the data provided by the client, it would appear that the electrical consumption at site is fairly
accurate. There are no individual meters monitoring oil consumption, Gasoil and LPG consumption is
based on monthly / quarterly receipts. Unfortunately, these do not provide adequate granularity to carry
out an accurate regression analysis. As months with no oil / LPG deliveries would not be adequately
represented on the assessment.
The nearest weather station with a good dataset available was the Ramsey station in Cambridgeshire andhas been used in the assessment.
The degree day plot allows a comparison with weather related measure. This shows the
relationship between the actual external temperatures and the gas consumption on site.
In the equation within the graph:
The R2 regression value represents the degree of scatter about the line of best fit. The R2 value
for a perfectly controlled system would be unity (R2=1) and anything above 0.9 is reasonable.
The y-intercept shows the energy needed by the building regardless of the external

temperature. This is known as the weather unrelated demandfor instance boiler losses and
hot water.
The slope of the line shows extra kWh required for each unit increase in degree day value, or
increase due to lower external temperatures.
The scatter of the graph (an R2 value of 0.91) suggests a reasonably good controlled heating system
and would indicate room for improvement with the control of the system.
The slope of the characteristic line indicates a weather-related demand of about 1645.8 kWh per
degree day. It would appear that this is unusually high for a site which is maintaining a wide dead
band of 15-24 Deg C in temperature control in the barriers. We would recommend that this be
investigated further.
The site also uses Gasoil for heating in the office block and for the generators. Gasoil constitutesabout 1.2% of the total heating fuel consumed at site and does not represent a major energy
load.
Based on the information provided by the client with regards to gasoil consumption, we have
carried out a regression analysis for the office area. Unfortunately, we have a poor dataset for
Gasoil consumption at site. As expected, there is poor correlation and regression due to the
quality of data available.

4.0 Assessment Findings and Observations
HVAC systems at site could be broadly divided into two categories, one catering for the broodand stock and the other catering to the whelping puppies.
4.1AHUs serving Buildings 1,2a,2b,4,5,11,12,24,25,25a,26,27,28
Buildings 1,2a,2b,4,5,11,12,24,25,25a,26,27,28 house the brood, and stock. These buildings are served
via a primary Air Handling Unit (AHU), these are constant volume systems providing fresh tempered air to
the barriers. The Primary AHUs are a once through type units with the extract air from the building
vented through openable louvers. Unfortunately, there is no recorded information at site to enable us to
carry out an assessment of air flow rates / energy consumption of these buildings.
The AHUs for these buildings are fairly basic, with air being heated by gasoil / LPG fired heaters. The
centrifugal fan is housed within an enclosure, and connected to air socks which serve the barriers. This
arrangement results in high eddy losses and is not recommended. It would appear that thes e AHUs do
not have adequate level of filtration. There is no data available at site indicating air flow rates of these
AHUs, air socks was found to be damaged in building 2a, many of the air socks were dirty needing a
cleanup.
Based on Home Office regulations, some form of cooling is required to provide temperatures between 15-
24 Deg C for beagles to deal with extreme ambient temperatures. Based on the site operational log, the
gas fired burners are 30 years old well past their recommended life and are showing signs of increasing
failure, this has resulted in an inability to meet the HO recommended peak temperatures.
4.2 Ventilation and heating for buildings 16,17,18,19,20,21
Buildings 16,17,18,19,20,21 houses the Whelping puppies, ventilation for these buildings is provided via
rudimentary supply and extract wall mounted fans coupled with a gas fired heater located within the
buildings along with localised infra-red heaters in the cages. Home Office regulation for puppies requires a
local environmental temperature of 26-28 Deg C for at least the first 5-10 days of life. Unfortunately,
there is no recorded information at site to enable us to carry out an assessment of air flow rates / energy
consumption of these buildings.
It is not clear how these parameters are being recorded / monitored at site.
4.3 Admin Building
The admin building is served via an LPHW radiator system with natural ventilation, there is no cooling in
the admin / security building apart from the cooling provided by the heat pump in the archive room.

4.4 DX Systems
The site has a DX system providing heating and cooling for the Archive room, the units runs continuously
(24/7) and is locally controlled. No documented records were available regarding maintenance of filters.
The refrigerant used in the units is R410A. On inspection there was no evidence of leakage and the units.
The areas around the condensing coil were generally free of debris and obstructions.
4.5 Boilers
The site has gas fired boilers providing Heating and DHW to the small admin offices located within each
building all across the site. These boilers are on a time clock and controller. During the survey, it was
noted that these are not being optimally used, consideration should be made to incorporate weather
compensation to improve energy efficiency.
DHW for male and female change areas in some buildings is provided via a point of use standalone
electric water heater.
4.6 Oil Tanks
As the site does not have a mains gas supply, all heating and DHW services are via Oil tanks and LPG tanks
located at the following locations:
During the survey, it was noticed that the LPG tanks had a proper concrete plinth, the oil tank bunding for
the admin block was not compliant with the Oil storage regulations. Failure to comply is a criminal
offence. The site could be fined up to 5,000.
DEFRA can serve a notice under section 161A Water Resources Act 1991 (works notice) to make the site
improve the oil storage standards. Failure to comply with a notice is a criminal offence and may result in
prosecution.
4.7 Domestic Hot Water Provision
Domestic hot water is provided by gas fired DHWS generators providing heating and hot water to the
various blocks, employing a decentralised system. These boilers have a centralised controller, some of
the timers on these controllers were out by 1 hour suggesting that they have not been changed to British
Summer time. The hot water is circulated within the building to its points of use thereby minimising
heating losses. The site has hard water with large calcium carbonate deposits and has maintained rigorous
water softening maintenance policy.
It is recommended that all tanks be de-scaled annually as part of the L8 service.

4.8 Asbestos roof
Buildings 11,12,16,17,18,19,20,21,22,23,24,25,25a,26,27,28 have asbestos roofing, it would appear that
the roofing due to age has become extremely fragile. An asbestos register could not be identified at site,it is a legal requirement under the Control of Asbestos Regulations 2006 (Regulation 4).Consideration
should be made to upgrade the roofing to improve energy performance of the building.
4.9 Water consumption
The sites water demand is met through a single water mains supply, it has a large demand of water
namely for cleaning the cages, and for consumption by animals. During the survey, a Reverse Osmosis
(RO) plant could not be identified, we would assume that the water is currently not being additionally
treated. Water saving devices like spray taps can help reduce water demand at site. We would
recommend that the site carry out a water audit to determine water consumption / savings.
4.10 Lighting
Lighting at site is generally in good order with a combination of Fluorescent T5 light fittings in the barriers,
and office areas. The Lux levels in the office areas were between 380 Lux and 600 Lux in some areas,
which is quite acceptable for an office environment and complies with the CIBSE Lighting Guide (LG7)
regulations, Lighting Guide 7 (2005): Office lighting and the BS EN 12464-1:2002 Light and lighting -
Lighting of work places - Part 1: Indoor work places.
Lighting in the production areas consists of T5 Fluorescent Light fittings. Lux levels measured in the
production areas were within an acceptable range.
We would recommend that the lighting in the offices be integrated with Energy efficient lighting controls
with PIR occupancy switches with daylight linked dimming thereby reducing energy bills further. We
would recommend these lighting controls; they have a simple payback of less than 2 years.
Lighting for the production areas and stores are recommended to be changed from the existing T8
Fluorescent lighting toHF T5 tubes along with intelligent control to take diurnal / seasonal patterns of the
rodents.
A lighting survey had been undertaken, the results of the audit have been enclosed as separate report.
4.11 Building Management Systems
The site does not have a BMS and was found lacking of an effective control strategy at site, it would
appear that only Building 3 is connected on the BMS with out of range alarms with the graphic front end
located at Hillcrest. Operational problems are being indicated by the site personnel with no means of
viewing control parameters at site, it is highly recommended that the site incorporate a BMS outstation
with all plant operations on a BMS outstation to have effective control of critical monitoring parameters
to ensure HO compliance.

4.12 Building Fabric
Building Fabric at site presents a legacy picture, with some buildings constructed recently having a sound
building fabric and U values, while others which were constructed in the 1980s have a poor buildingfabric and U values, the roofs of the older buildings had asbestos which appears fragile and in need of an
upgrade. Consideration should be made to upgrade the building fabric and improve the air tightness and
hence energy performance of the buildings which appears to be in excess of 30 years old. An Asbestos
Risk register for the site is recommended in order to adequately monitor and control asbestos at site.
4.13 Automated Metering / Monitoring and Targeting
The site does not have adequate sub metering on any buildings, individual auxiliary plant serving the
building do not have a dedicated energy input or hours run meter. Meter readings are read and recorded
on a regular basis and this data was provided by the client prior to attending site. Additionally this setup isnot ideal as it does not reward energy efficiency in anyway.
It is recommended that the scope of metering be reviewed to install appropriate metering at least to the
more significant energy consuming air conditioning plant, and subsequently to record the consumption on
a regular basis.
it is preferable to automate the Utility consumption of major ancillary loads in order to identify individual
energy consumption patterns and thereby seek energy reduction, by various options available to the
client which include installation of AMR (Automated Meter Reading) to capture half hourly Energy
consumption data in order to monitor energy consumption and to gather real time energy profile data as
part of the drive to reduce energy and running costs.
We would recommend that monitoring & targeting system be introduced to the site to allow a more
detailed review of energy use on the site.
A good M&T system would enable the following:
establish current consumption
compare current consumption with historical data and benchmarks
set future targets
compare current consumption with the targets
identify trends in consumption
Produce exception reports when targets are exceeded.
Accurate apportioning of utility costs for the different tenants

It is estimated that there is a 5% reduction in energy consumption due to an effective M & T
system.
4.13 Auxiliary Services
In addition to heating, lighting and hot water, the admin building uses electricity for powering the building
IT systems, printers, photocopiers, computer workstations, kitchen and tea room preparation areas.
These Auxiliary services should be switched off when not in use to conserve energy.

5.0Summary Condition Appraisal, Filtration and Maintenance Overview
The AHUs serving the building are rudimentary and do not incorporate adequate level of airfiltration in them, the air socks in building 2a was found to be torn, air flow rates of these units are
unknown it is not clear whether current home office regulation of 10-12 ACPH are being achieved.
Some of the AHU fan section had foliage and debris in them indicating no filters were present, a
minimum of F6 level of filtration would be needed to protect the fans and air socks from airborne
dirt and debris.
In general, the majority of plant and equipment is in operation, although a number of issues
observed whilst on site need to be addressed and these are commented on in paragraphs to follow.
Based on the Code of practice as advised by the Home Office for the housing of animals in designated
breeding and supplying establishments which were prepared in consultation with Laboratory Animals
Breeders Association (LABA) Guidelines on the care and housing of animals bred for scientific
purposes, the Association of the British Pharmaceutical Industry (ABPI), British Laboratory Animal
Veterinary Association (BLAVA), Institute of Animal Technology (IAT), and the Laboratory Animal
Science Association (LASA), the ventilation rate of the room is related to stocking density and to the
heat generated by animals and equipment in the room (thermal load).
In order to maintain suitable air quality 10-12 changes of fresh or air conditioned air per hour
distributed throughout the room would normally be adequate for rooms with high stocking densities
eg dogs etc. It is highly recommended that the ventilation system complies with European
regulations Directive 2010/63/EU which will take full effect from 1 January 2013.
At present it would appear that none of the AHUs are capable of meeting the 15-20 ACHP criteria
laid down by the code of practice.

Buildings 16,17,18,19,20,21 housing the Whelping puppies, have uncontrolled ventilation provided
via rudimentary supply and extract wall mounted fans coupled with a gas fired heaters along with
localised infra-red heaters in the cages. Home Office regulation for puppies requires a local
environmental temperature of 26-28 Deg C for at least the first 5-10 days of life. It is not clear howthese parameters are being recorded / monitored at site. These buildings do not have any filtration,
thereby rendering all these buildings susceptible to airborne particulate matter / airborne viruses, a
virus strain from the nearby testing facility could wipe out the entire stock of Whelping puppies and
poses a business continuity risk.
Evidence provided at the time of inspection, suggests that a comprehensive planned preventative
maintenance (PPM) regime is needed at site, which includes an effective reactive maintenance
regime supported by onsite maintenance personnel.
Filtration
As is evident from the above pictures, it would appear that air filtration at site is very poor. As the
site operates an animal research facility with emphasis on breeding pure breeds, we would
recommend that consideration should be made towards setting up a filtration standard at site. It is
recommended that air filtration at site be upgraded to F9 or F13 depending on the level of protection
to prevent airborne viruses / pathogens from contaminating the pure breed being bred at site.
The site also houses a private research facility, Churchill Labs where it is presumed, where critical
research takes place. It is recommended that consideration be made to review air filtration / extract
at the facility in order to safe guard operations downstream.
The site does not have extract ductwork which could provide a possible path for airborne viruses and
contaminants to enter site, it is important that the entire ventilation philosophy be reviewed at site.
We envisage that this is critical to the operations at site and presents a business continuity risk.
Specific Fan Power
Whilst on site, power consumed by all large supply and extract fans (including losses through
switchgear VSDs) was measured in order that Specific Fan Power (SFP) of each system may be
determined and compared with current levels recommended in the Non- domestic Heating, Cooling
and Ventilation Compliance Guide.
Specific Fan Power of the AHUs could not be calculated due to lack of data available regarding their
flow rates. The AHUs currently do not meet the required specific fan power detailed in the Non-
domestic Heating, Cooling and Ventilation Compliance Guide. Consideration should be made to
review the air flow rates by re-visiting the ventilation design and BMS philosophy is also
recommended.

6.0 Documentation, Maintenance, Cleaning & Metering
All documentation required to compile this report was either provided prior to attending site by theFMT, whilst on site. The following list of documentation was requested during the site inspection:
Operation and Maintenance manuals
Plant Installation drawings
Planned Preventative Maintenance Records
Floor Plans (used for the calculation of ventilation air change rates)
While reviewing the onsite records, there were no Operational and Maintenance manuals,
Commissioning Data for the Mechanical plant including commissioning results ( including flow rates)for the AHUs, were not found with the O&M Manuals. TheAs Built record drawings and subsequent
amendments were not available at site, probably due to the fact that there are no records available
at site due to the age of the building. Planned Preventative Maintenance Records indicating the
frequency of maintenance / schedules and building log book were not available during the visit.
It is recommended that the site carry out a complete re-commissioning of all the blocks, in order to
validate air flows, water flows, fan ESPs and ACHP rates across various barriers in the various blocks.
The indicated service frequency should comply with normal practice and the recommendations of
HVCA SG20 (Standard Maintenance Specification for Mechanical Services in Buildings - Section 9
Packaged Chillers), indicating that work has been untaken and no details of the content of the service
visit i.e. major or minor. A separate service report sheet is recommended to confirm the detail of the
work undertaken.
Duct Cleaning
It would appear that the ductwork serving the Buildings has never been cleaned and disinfected, this
problem is compounded by the fact that there is inadequate levels of air filtration while we would
advise that these systems be periodically cleaned and disinfected to prevent build up of debris, thus
encouraging microbial growth. The client has stated his concern of long downtimes and an increased
exposure for revenue generating processes.
We would recommend that while the AHUs are being replaced, a temporary Air Sock be installed
which would form part of a standby system and connected to the AHU, while the ductwork is being
cleaned. This would help in minimising downtime.

Metering
No individual items of plant serving this building has its own dedicated energy input or hours run
meter. Meter readings are read and recorded on a regular basis and this data was provided by theclient prior to attending site.
It is recommended that the scope of metering be reviewed to install appropriate metering at least to
the more significant energy consuming air conditioning plant, and subsequently to record the
consumption on a regular basis. CIBSE TM39: Building energy metering provides guidance on
developing a metering plan and should be consulted for best practise and advice.
It is also recommended that AMR (Automatic Meter Reading) for all the tenants is introduced, this
would automate the billing process, it also includes trends in consumption etc which would help the
tenant to identify wastage in energy and help reduce energy consumption. As a general rule, a 5%
energy saving is expected by incorporating an AMR.

7.0 Project Recommendations and Capital Investment Opportunities
Recommended Energy Projects
The Audit-identified projects have been grouped into 4 different categories namely Statutory /
Regulatory requirements, Low cost options, medium cost (Infrastructure upgrade) and Sustainability
projects which are discussed below. All costs included here are budget costs (25% subject to detailed
design):
Note: Regulatory Projects may not be energy reductions, but EECO2 will ensure energy efficient solutions
are proposed to minimise increases.
Regulatory Projects:
1. AHU Ductwork Cleaning: The Supply air socks on the AHUs were found to be dirty. It would
appear that there is poor air filtration regime at the air intakes at the heaters. Existing ductwork
has not undergone a cleaning regime. Airborne particulate matter present at site clearly presents
a health hazard.Minimum F7 requirement for protection, along with yearly washing should be
carried out, recommend a spare set of socks to allow for cleaning.
Budget Cost:1500 for cleaning and disinfecting per AHU to provide a hygiene and safety deepclean.
2.
Measurement of HVAC System: Based on the Code of practice for the housing of animals indesignated breeding and supplying establishments, Laboratory Animals Breeders Association
(LABA) Guidelines on the care and housing of animals bred for scientific purposes. The Industry
(Home Office) Guidelines specify 10-12 changes of fresh or air conditioned air per hour
distributed throughout the room for dogs. It would appear that the air flow rates in the Buildings
currently do not meet the regulatory standards mentioned therein. It is advisable that the
ventilation system be validated in all the Blocks as part of the Home Office regulatory
compliance.
Budget Cost:We would recommend that a budget Capex of 15K be set aside for carrying outmeasuring and checking of the HVAC systems at site in order to determine current air changes
being achieved.
3. Energy Performance Certificate (EPC) / Display Energy Certificate (DEC): An
Energy Performance Certificate (EPC) is a statutory requirement in order to comply with the
Energy Performance of Buildings Directive and UK National legislation. While, it is not mandatory
for the site currently as it is privately owned, and would be needed while buying and selling the
-
8/12/2019 Harlan Labs Wyton HVAC Energy Audit R2
30/45
HVAC Energy AuditHarlan Labs, Wyton
30
premises. The client might wish to have an EPC certificate in order to determine the buildings
asset rating.
Display Energy Certificate (DEC) while not mandatory, shows the actual energy usage of abuilding, the Operational Rating, and help the public see the energy efficiency of a building.The
DEC should be clearly displayed at all times and clearly visible to the public.A DEC is valid for 12
months and needs to be updated annually. The accompanying Advisory Report is valid for 7
years. The client might wish to carry out a DEC for public display in order to improve Public
Relations (PR) in the local community.
Budget Cost: A Budget cost would be 3K for carrying out an EPC and report, while a DECwould cost about 1200. As CIBSE accredited Energy Assessors, we can carry out the above works.
4.
Oil Tank plinths:During the survey, it was noticed that the oil tank plinths was not compliantwith the Oil storage regulations, some of the oil tanks were mounted on bricks, this is not as per
DEFRA guidelines for oil storage. Failure to comply is a criminal offence. The site could be fined
up to 5,000 by DEFRA.
Budget Cost: We would assume that the cost of Civil works for providing adequate plinthsincluding providing an adequate concrete base for the Oil tanks located in the Admin courtyard
and other areas at site would be 30K. We shall be happy to review this to make it DEFRA
compliant.
5. Asbestos Risk Register: During the survey, it was noticed that Buildings
11,12,16,17,18,19,20,21,22,23,24,25,25a,26,27,28 have asbestos roofing, it would appear thatthe roofing due to age has become extremely fragile. An asbestos register could not be identified
at site.
The duty to manage asbestos is a legal requirement under the Control of Asbestos Regulations
2006 (Regulation 4). It applies to the owners and occupiers of commercial premises (such as
shops, offices, industrial units etc) who have responsibility for maintenance and repair activities.
In addition to these responsibilities, they also have a duty to assess the presence and condition
of any asbestos-containing materials. If asbestos is present, or is presumed to be present, then it
must be managed appropriately. Failure to comply is a criminal offence; exposure to asbestos
can lead to lung cancer and other respiratory ailments rendering the company liable to
negligence.
Budget Cost: We would assume that the cost of carrying out an asbestos survey at siteincluding preparing an asbestos risk register at site would be 30K. We shall be happy to review
this in more detail should the client wishes to pursue this further.

Quick Wins:As part of the assessment, a number of quick wins or JDIs (just Do it) were reviewed. These included:
Boiler optimisation,
Adding weather compensation to the office boilers, Insulating the heating system and DHWS system.
Unfortunately, these measures are not viable as the boiler is showing increasing signs of deterioration
due to its age. The heating and DHWS system at site is highly decentralised with a standalone boiler
for the offices in the barriers, DHWS is provided via standalone combi boilers and/ or point of use
electric heaters.
Low Cost Projects:
6.
Energy Efficient Boilers for the Admin Block: The existing oil fired boilers in theAdmin block were installed in the 1980s is in a poor condition, it is well past the CIBSErecommended design life expectancy of 15 years. Due to their present age, there is insufficient
combustion of the boilers resulting in acrid smoke in the offices during start up. The frequency of
maintenance has increased many fold. These boilers have an efficiency of 60-70%.
We would recommend that these be replaced with energy efficient Boilers which have an
efficiency greater than 95%, the boilers selected shall be fully modulating, have weather
compensation and incorporate an intelligent boiler controller for energy optimised operation.
This would reduce energy consumption in excess of 30%.

7. Water Saving Devices:The sites water demand is met through a single water mains supply,with a large water demand namely for cleaning the cages, and for consumption by animals.
Water saving devices like spray taps/ flow restrictors can help reduce water demand at site. We
would recommend that the site carry out a water audit to determine water consumption /
savings.

9. Energy Efficient AHUs:AHUs at site could be broadly classified into 2 categories, namelythe brood and stock housing and the Whelping Puppies building.
The AHUs serving Buildings 1,2a,2b,3,4,5,11,12,24,25,25a,26,27,28 are more than 30 years old
and showing signs of failure, it is our considered opinion to replace the se with Low Energy AHUs
capable of providing 10-12 AHCP for these Buildings, while incorporating system redundancy to
allow the AHUs to function during downtime.
Buildings 16,17,18,19,20,21 housing whelping do not have an AHU and relies on wall mounted
fans for achieving the air change rates, It is recommended that these areas be reviewed for
compliance.
Due to the fact that the AHUs serving the buildings are more than 30 years old and showing
signs of failure, along with the fact that these AHUs are not capable of providing 15-20 AHCP as
mandated by the European directive which comes into effect in 2013.
There are two options available for review:
A Twin Fan system, operating at 50% duty each, capable of ramping up to design duty during
maintenance of a single system.
Incorporating a Fan Wall Technology system, with a 2N redundant system. The benefits of Fan
Wall Technology include:
Dramatically Shorter Footprint
Quiet Operation and Low Vibration
Optimized Performance and Energy Efficiency by providing more uniform airvelocities across filters and coils.
Redundancy by Protecting critical assets and minimizing downtime exposure
for revenue generating processes
Lower Maintenance Costs
It is worth noting that the current AHU does not appear to comply with the Home Office regulations,
or the proposed EU regulations. Current levels of filtration on the AHUs arenot adequate.
The energy savings shown below are a cost comparison between a standard AHU and an energy
efficient AHU when considering an upgrade.

10.Heating and Cooling Provision for the Energy Efficient AHUs:Heating for the site iscurrently provided via Gas fired burners, there is no cooling at site. In order to meet the Home
office criteria and to comply with the proposed EU regulations, it is advisable that cooling be
incorporated.
a) Gas Fired BurnersThe Gas fired burners have operational problems at site indicate a very high frequency of failure
of the gas fired heaters, primarily due to the age of the plant. It is also worth noting that these
burners have a poor efficiency of around 55-60%. It is recommended that these be replaced by
energy efficient burners along with an effective control strategy including weather
compensation.

b) DX UnitsDX units present a less expensive alternative to incorporate cooling at site. However, it should be
noted that the electrical supplies at site are stretched thereby requiring exploring alternatives
including reinforcing the electrical supply to site.
There exists an alternative approach to this problem which has been included as a sustainability
project. Please refer to Project 12 for more details.

Sustainability Projects:
Sustainability projects have been included with a view to address some shortcomings at site namelylack of spare provision in the electrical infrastructure at site, thereby requiring expensive electrical
infrastructure upgrades. We have also looked at options where fuel could be locally sourced within
the local community thereby resulting in better community cohesion / PR. It would also result in the
site being carbon neutral.
12.Gas Based Heating and cooling
As the site is considering installing cooling to comply with home office regulation along with the fact
that the heaters are in excess of 30 years old and in need replacement, it is therefore recommendedthat a gas based heat pump solution providing heating and cooling be explored thereby providing both
heating and cooling at site.
It is worth noting that the electrical infrastructure at site is stretched, any additional cooling demands
for compliance would require additional electrical reinforcements at site. This solution does not
require expensive electrical infrastructure upgrades.
We can provide budget costs of a Gas based heat pump once treated floor areas of these buildings are
made available.
As part of the assessment, we have also explored an option for a Trigeneration CHP plant at site. Thesite is situated in a rural area surrounded by farmland with an opportunity to use crop waste as fuel,
thereby helping the local community and improving community cohesion. There are government
incentives in the form of ROCs (Renewable Obligation Certificates).
A ROC is the green certificate issued for eligible renewable electricity generated within the United
Kingdom and supplied to customers in the United Kingdom by a licensed supplier. Co-firing of crop
waste results in 1.5 ROC per MW produced, each ROC is worth approximately 40 per MW produced.
While this option is by far more expensive than others investigated, we believe this would help the site
reduce the negative press / publicity it has attracted over sometime while helping to reduce energy
consumption and result in becoming a carbon neutral site. We shall be happy to review this in detail
and provide budget costs should the client wish to progress this further.
An option to explore would be to seek services of an Energy Supply Company (ESCO), who would set
up the proposed plant and infrastructure while seeking long term energy contracts from the site. This
would result in the client saving on capital outlays and expenditure while benefitting from a carbon
neutral operation.

Sun Pipes: The Lighting system at site is generally good with ample Lux levels achieved withinthe barriers. The site has managed to replace nearly all of the T8 fluorescent light fittings with T5
light fittings.
Lighting at site represents a major load due to lack of cooling at site, consideration could be
made to reduce electrical energy consumption by incorporating sun pipes and incorporating
dimming features on the existing T5 light fittings, this would help reduce the need for procuring
additional electrical supplies at site due to added cooling requirement to comply with the

There exists an opportunity to reduce energy consumption by reviewing the process cooling
loads at site. We would propose to review the process cooling loads at site and come up with a
proposal to use evaporative cooling for the AHUs coupled with Bore Hole cooling thereby
resulting in massive energy savings to be made. Typical ground water supply temperatures are in
the range of 6-10C and typical re-injection temperatures 12-18C (subject to the requirements
of the abstraction licence).

Building fabric improvement Projects:
15.Thermal Image Survey: Building fabric has been in existence for more than 30 years, which
has resulted in high heat losses from the building. It is recommended that a thermal Image
survey be carried out site wide in order to determine the leakage paths in the building fabric
including windows, walls, roofing, piping, ductwork etc. This would help recommendations for
building fabric U value improvement, relevant upgrade on leakage paths etc.

than 30 years, which has resulted in high heat losses from the building. Consideration could be
made in the future to improve the building fabric of the buildings by improving windows, walls
and by adding additional insulation.
It is worth noting that Buildings 11,12,16,17,18,19,20,21,22,23,24,25,25a,26,27,28 have asbestos
roofing, which due to age has become extremely fragile, consideration should be made to
upgrade the roofing in these buildings.

Budget Costs for Building Fabric Improvement projects: subject to detailed
assessment
*This is a capital intensive project with low payback periods.It is difficult to put a Budget cost for
this project, as a detailed study is required. This is complicated due to the fact that we have
asbestos at site which requires removal and safe disposal.

Enhanced Capital Allowance (ECA) and funding
Enhanced Capital Allowances (ECAs) enable a business to claim 100% first-year capital allowances on
their spending on qualifying plant and machinery.
There are three schemes for ECA's
Energy saving plant and equipment
Low carbon dioxide emission cars and natural gas and hydrogen fuelling infrastructure
Water conservation plant and machinery.
Businesses can write off the whole of the capital cost of their investment in these technologies
against their taxable profits of the period during which they make the investment. This can deliver a
helpful cash flow boost and a shortened payback period.
For products on the Energy Technology Product List, a claim can be made on the cost of the
equipment itself, and other costs directly involved in installing it. These include:
Direct Transportation the cost of getting equipment to the site.
Direct Installation cranage (to lift heavy equipment into place), project management costs and
labour, plus any necessary modifications to the site or existing equipment.
Professional Fees if they are directly related to the acquisition and installation of the equipment.
Any remote or indirect costs do not qualify for the ECA for example, staff time spent taken to
select the right equipment. Only new equipment is eligible for an ECA used or second hand
equipment does not qualify.
All the plant selected falls under the Energy Technology product list, there by all the entire project
costs could avail ECA benefit. Details of how to apply for ECA is available on the DECC website, we
can also provide assistance towards applying for ECA benefit.

9. Conclusions
The report highlights the preliminary energy, operational and management issues associated withHarlan Labs, Wyton. it is advisable that a ventilation and filtration philosophy be incorporated in
order to address business continuity risks and to meet regulatory compliance, it preferable to
automate the Utility consumption of major ancillary loads in order to identify individual energy
consumption patterns and thereby seek energy reduction, by various options available to the client
which include installation of AMR (Automated Meter Reading) to capture half hourly Energy
consumption data in order to monitor energy consumption and to gather real time energy profile
data as part of the drive to reduce energy and running costs. A BMS system for plant automation /
control is preferable to realise energy savings through incorporating energy optimisation schedules.
