*Until 1965 there were no national Building Codes.Previously Local Bye Laws prevailed and modes of construction varied from one part of UK to another. First Building Regulations did not include requirements for Energy Conservation these came in 1976 Building Regulations are divided into sections and associated Approved Documents (ADs) Part A: Structural Maters Part B: Fire Part F: Ventilation Part H: Heat producing appliances Part L: Energy Conservation and more recently carbon emissionsEach Part has associated Ads e.g. for Part L the Approved Documents were originally ADL. Subsequently divided into ADL1 and ADL2 covering dwellings and non-dwelling separately Then subdivided further into ADL1a and ADL1b covering new and existing buildings. Introduction of Building Regulations
*First introduced as Part L in 1976Basic Statement largely following what was then common practicee.g. cavity walls brick cavity block with no insulation: - no insulation in floor, minimal insulation in loft.1994: First attempt to address overall annual energy consumption, although elemental method of compliance was still permitted2002: Carbon Index introduced2006: Target Emission Rate and Dwelling Emission Rate introduced.2010: Came into force Oct 1st 2010 relatively minor updates on 2006 RegulationsChanges in the Heating Standards of Houses*

Compliance to Building RegulationsCompliance to Building Regulations may be achieved by one of several alternative methods.Elemental MethodSpecifies maximum U-value and perhaps maximum glazed area valid until 2002 RegsTarget U-value weighted average U-value allowed some flexibility in designSAP Rating (1994 Regs) economic assessmentCarbon Index (2002 Regs)Target Emission Rate (Current Regs)*
1994 Regulations: A step changeSingle glazing could no longer be used routinely for domestic buildingsGlazed area 22.5% of floor area50% greater than 1990 regs50% potential saving lostStandard Assessment Procedure (SAP) rating for new buildings0-100 higher the betterNo target SAP but requirements relaxed if >60SAP 80-84 Regs automatically satisfiedIncludes energy running costs in calculationTrade offs permittedDoes not specify ventilation rates but gives method for estimatingMake allowance for solar water heating if fittedInclude hot water requirements

Building Regulations 2000Implemented April 2002Energy rating methodSAP replaced by Carbon Index method for complianceSAP ratings still to be calculated and notified to building control bodiesRequirement of heating & hot water changed to encompass overall system performance, not just controlsBoiler seasonal efficiency, inspection & commissioning includedNew requirements for efficient lighting systems & provision of information for householdersStandards of fabric insulation improvedLower (better) standards (loft insulation)Reductions in U values (towards technical limits)Changed methods for calculating U valuesLower U values for windowsBased on sealed double-glazed units with low emissivity panesArea of glazing increased to 25% floor areaTarget U-value method retained but provisions for trade-offs improved.*
Compliance procedures 2000 RegulationsThree methods to demonstrate compliance with Building Regulations:Elemental approachTarget U-Value methodCarbon Index
1. Elemental approach valid if specific conditions are met.Heating must be gas, oil, heat pump, CHP DH, biogas or biomassU-values
EU Energy Performance of Buildings Directive (EPBD) 2002/91/ECAims at improving energy efficiency, carbon emissions from buildings could be reduced by 22%.
Objectives of the Directive:To promote the improvement of the energy performance of buildings within the EU through cost effective measures; To promote the convergence of building standards towards those of Member States which already have ambitious levels.
Measures include:Methodology for calculating the energy performance of buildings; Application of performance standards on new and existing buildings; Certification schemes for all buildings; Regular inspection and assessment of boilers/heating and cooling installations.

Building Regulation: Compliance SummaryUp to and including 2000 Regulations Elemental Method specifying U-values of fabric elementsTarget U-Value allowed some flexibility of design.SAP Rating an economic measure only permitted for compliance in 1994 Regs.2000/2002 RegulationsCarbon Index Method- a distorted Carbon Measure2005/6 RegulationsDwelling Emission Rating must be better than Target Emission Rating. Latter is a derivative of the Target U-Value Method.2009/10 RegulationsRetains DER and TER but expects a 25% improvement on performance over 2005/6 standards*
Carbon Index Calculations (2000 and onwards regulations)Attempts to assess the true environmental performance of a buildingFollow Standard Assessment Procedure to calculate Total Energy RequirementCalculate CO2 emissions for buildingCalculate Carbon Factor (CF)CF=CO2 (TFA+45) where TFA is total floor spaceCarbon Index (CI) CI=17.7-9.0 log10(CF)Complication of scale >102000regulations indicated that compliance is 11kg CO2 per m2 carbon index of 8 If true scale was used Zicer & Elizabeth Fry would score 13.5 out of 10.*
Critique of the Standard Assessment Procedure (SAP) Energy efficiency index but gives a rating that is monetary based not energy basedAssumes a general heating level in house two zones (one living area one other). Does not allow for actual temperature settings. Hot water requirements based on floor area formula not occupancyIncidental gains based on floor area not occupancyProblem: Is this a sensible approach? If occupancy changes then Rating would change, but it is difficult to compare actual readings with predicted. Alcantar (2008) found problems with methodology for incidental gains etc2010 Regulations partly address issue with regard to occupancy e.g. if TFA > 13.9: N = 1 + 1.76 [1-exp (-0.000349 (TFA-13.9) )] + 0.0013 (TFA-13.9) if TFA 13.9: N = 1 N is the assumed number of occupants, TFA is the total floor area of dwelling.
*
2006 Regulations Dwelling Emission Rate is method of compliance- essentially the 2010 Regs are similar with only minor variations in detailCriterion 1A Dwelling Emission Rating (DER) must be calculated taking due account of the U-values, the size, the types of heating etc using the Standard Assessment Procedure (SAP) The DER must be shown to be less than the Target Emission Rating (TER) which is computed with the same size of building and U-values meeting those as specified in the Regulations.Essentially this is a derivative of the target U value methodDetails are shown in Section 2.1.11 of handout*
Criterion 2 limits on design flexibilityPerformance of the building must not be worse than a given standard. gives considerable latitude in design the old trade-off problem. However criterion attempts to limit this type of trade-off see pages 5 and 6 of the Approved Document
Criterion 3 Limiting effects of solar overheatingRequires that the effects of overheating in summer must be addressed*2006 Regulations Dwelling Emission Rate is method of compliance - essentially the 2010 Regs are similar with only minor variations in detail
Criterion 4 Quality of ConstructionCriterion requires evidence of actual performance e.g. changes arising from design modifications, quality of workmanship. Some of the requirements involve pressure testing the building to ensure they have achieved those used in the design specification.
Criterion 5. Providing InformationRequires information on the maintenance and operation of the building to be made available. *2006 Regulations Dwelling Emission Rate is method of compliance - essentially the 2010 Regs are similar with only minor variations in detail
Critique of the Standard Assessment Procedure (SAP) Standing charge ignored for electricity, included for gas. Oil doesnt have a fixed charge Can lead to some perverse consequencesLower efficiency oil heating can give a higher SAP rating than more efficient gasEnergy Cost Deflator is needed Unnecessary complication that allows for inflationBut does not allow for differential prices changes between fuelsSAP 1995 possible SAP rating of over 110SAP of 100 readily achievable SAP 2001 widened scale (over 120) for consistency with existing scaleSAP 2005 changed scale to have 100 for zero energy house means all previous calculation have to be redone.Now possible to get > 100 if a house is carbon negative i.e. will be exporting more energy than it consumes. *
CALCULATION of SAP RATINGWhile the Standard Assessment Procedure makes sense the final Rating known as the SAP Rating creates problemsThe SAP rating is related to the total energy cost by the equations:Energy Cost Factor (ECF) = deflator total energy cost / (TFA + 45) (10)The total energy running cost includes not only heating but also requirements for hot water, lighting etc as well as pumps/fans associated with heating. These are proscribed costs according to a table which are not actual costs.The deflator is a factor which varies according to energy costs and is intended to keep SAP Ratings constant with time irrespective of changes in fuel prices - this has not been the case in the past.
CALCULATION of SAP RATING 2010First work out the Energy Cost Factor (ECF)where ECF = deflator total energy cost / (TFA + 45) and TFA is the total floor area of the dwelling. [the energy cost factor initially has been set at 0.47]if ECF >= 3.5, SAP 2009 = 117 121 x log10(ECF)if ECF < 3.5, SAP 2009 = 100 13.95 x ECF
Note (q) on page 151 of the SAP document indicates deflator will change to keep SAP Rating constant overall but that for individual fuels the Rating will vary.
Impact of Changing Methodology on SAP RatingThese changes are relatively small compared with changes in previous methodology changes i.e. 1995 2001 and 2001 2006.However these demonstrate the problem of using Economic Cost as a Key Factor in determining the SAP Rating

Climatic Issue with 2010 Calculations*Calculations have to take account of Climate Variations of Solar Gain for
Assessment of Cooling Requirements

Calculating the TERTER2010 = (Ch x FF x EFAh + Cl xEFAl) x (10.2)* (1 0.25) 25% improvement on 2005Where Ch is the energy requirements for space heating and hot water including any used in circulating pumps,Cl is the energy use for lightingFF is a fuel factorEFA is the relevant Emission Factor Adjustment and is a ratio of the emission factors used in the 2009 calculations divided by the equivalent ones in the 2005 calculations.
Improvements for 2010 - Environmental Impact Rating (EI)
Improvements for 2010 - Environmental Impact Rating (EI)Carbon Factor (CF) = (CO2 emissions) / (TFA + 45) where TFA is the Total Floor Areaif CF >= 28.3 EI rating = 200 95 x log10(CF)if CF < 28.3 EI rating = 100 1.34 x CF where the CO2 emissions are calculated according to the Standard Assessment Procedure
The EI rating is essentially independent of floor areaIt will vary slightly depending on actual plan shapeA house with zero emissions will have the EI at 100An EI > 100 if a house is a net exporter of energy.Primary energy requirements are also calculated in a similar way to CO2 emissions.
Letter Rating bands are assigned as followsIt applies to both the SAP rating and the Environmental Impact rating (why the SAP Rating??). Rating Band

*How has the performance of a typical house changed over the years?Bungalow in South West Norwich built in mid 1950sOriginal Construction Brick brick cavity walls Metal windowsSolid floor no insulationNo loft insulation
*Changing Energy Requirements of HouseIn all years dimensions of house remain same just insulation standards changeAs houses have long replacement times, legacy of former regulations will affect ability to reduce carbon emissions in future*
*Changing Energy Requirements of HouseImprovements to existing properties are limited because of in built structural issues e.g. No floor insulation in example shown.House designed to conform the Target Emission Rate (TER) as specified in Building Regulations 2006 and SAP 2005.
*Example:Heat house with condensing gas boiler ~ 90% efficientFor each unit (kWh) of heat provided. 1/0.9 = 1.11 units of gas must be suppliedCarbon associated with this ~ 0.21 kgDirect electric heating ~ 0.52 kgHeat Pump with Coefficient of Performance of 4Carbon emission associated = 0.52/4 = 0.13A 38% saving over gas.Note some people claim higher savings based on incorrect DEFRA carbon factor of 0.43Improved performance of heat pumps is possible with under floor heatingIssue of Fuel Choice for carbon reduction
*Changing Carbon Dioxide EmissionsNotice significant difference between using gas and oil boiler.House designed to conform the Target Emission Rate (TER) as specified in Building Regulations 2006 and SAP 2005.*

CRed
In the UK, each person emits 9.3 tonnes of carbon dioxide each year because of the energy we use. This is equivalent to 5 hot air balloons. Some of these emissions we can control directly as indicated above, but others are emitted on our behalf because of the services we demand and so we are indirectly resposible for these emissions. Examples include how and where we get our food from, do we get a full life of say 4 - 5 years out of our mobile phones or do we expect to change them every year. Other areas where we have indirect emissions are in our schools and hospitals which are services we all need to sustain our standard of living. These will increase your personal target above that shown above
