A dynamic thermal model was developed to determine whether the Wherry School

development is predicted to be adequately ventilated in order to avoid overheating

(as defined in Facilities output specification (FOS)).

Information on building fabric, usage requirements, environmental conditions,

planned systems, and other data were applied to a model built in IES’ Virtual

Environment software, based on the following assumptions:

Night-time cooling: Mechanical ventilation units will have the ability to

operate 24 hours a day to purge warm air if needed.

Louvre blinds (or similar) assumed present on all windows, with shading

coefficient of 0.5.

The layout and ventilation strategy were based on the latest drawings and

information from the architect.

It was concluded based on the results of the model that all regularly occupied

rooms can comply with the Facilities output specification (FOS) criteria

under current design assumptions therefore it is unlikely the building will

overheat.

This report has been prepared to analyse the feasibility of the

ventilation strategy proposed for the Wherry School development for

the purpose of maintaining acceptable internal air temperatures.

A thermal model of the building was developed, and a dynamic

simulation was run. The results of the simulation were compared

against the following criteria for internal conditions:

1.1 Facilities Output Specification

The facilities output specification states that all overheating procedures

for naturally ventilated buildings should follow the procedure set out in

CIBSE Technical Memorandum 52 which compares the internal

temperature against the three criteria shown below:

Criteria 1 - Hours of Exceedance

For schools, the number of hours that the internal-external temperature

difference (∆T) is greater than or equal to one degree (K) during the

period May to September inclusive shall not be more than 40 hours.

Criteria 2 – Daily Weighted Exceedance

To allow for the severity of overheating the weighted exceedance shall

be less than or equal to 6 in any one day.

Criteria 3 - Upper Limit Temperature

To set an absolute maximum value for the indoor operative

temperature the value of ∆T shall not exceed 4K.

The building will be deemed to fail the overheating design criteria if

any two of the three criteria are exceeded.

2.1 Geometry

The building layout, including room locations, window and door

locations and sizes and other geometry, including shading, was based

on drawings provided by LSI Architects. The building as modelled is

shown in Figure 2.1:

Further details of the drawings can be found in Appendix A

2.2 Environmental Conditions and Weather Data

The CIBSE Design Summer Year (DSY) weather data set for Norwich

was applied to the model to simulate weather conditions.

2.3 Activity Profiles

Classrooms, Staff Area’s and Teaching spaces

The profile for modulating occupancy, equipment, and other internal

heat gains were based on the NCM classroom occupancy profile for a

school day. This is shown in Fig. 2.2:

The Hall

To ensure that the Hall would be suitable during the peak of summer it

was assumed that this space would be occupied every day during the

week for 4 hours during the hottest part of the day as shown in figure

2.3 below:

The Dining Area

The dining area was assumed to be occupied every day during the

week for 2 hours from 12:00-14:00 as shown in figure 2.4 below:

Figure 2.4: Dining area occupancy profile

The windows in areas that are reliant on natural ventilation (see Section

2.6) are assumed to be openable between the hours of 06:45 and

18:00, and are assumed to open if a room becomes too hot (Ti > 24ºC

and Ti > To)1.

1 Ti = room internal temperature, To = outside temperature.

2.5.2 Equipment

Equipment gains in all classroom spaces were assumed to be 500W to

account for a modern energy efficient projector system.

Equipment gains in Staff areas and offices were assumed to be 300W

to account for personal computers as well as other equipment.

2.6 Systems

2.6.1 Ventilation

The majority of the teaching spaces within the Wherry school will be

mechanically ventilated via dedicated supply & extract fans with heat

recovery. The mechanical ventilation system is controlled using a

system that modulates the speed of the fan if the internal room

temperature exceeds 23°C at any point in time. This system also

benefits from the use of night time cooling to passively cool the space

during the evenings when the temperature is typically lower.

A full breakdown of the ventilation system strategy is shown if figure

2.4 below:

Some classrooms and staff offices without mechanical ventilation

systems will be naturally ventilated by openable windows. These

windows will operate to a minimum of 10° clear of any reveals and

obstructions as shown in figure 2.5 below:

The Hall will be naturally ventilated via a combination of opening

windows described above and roof turrets to provide sufficient cross

flow ventilation during periods of high occupancy.

2.6.2 Blinds

All windows within the school were assumed to include light coloured

blinds with a shading factor of 0.5 that operate during occupied the

hours stated in section 2.3 to limit the effects of solar gain and glare.

2.7 Calculation Methods

All modelling and simulation was carried out in the IES Virtual

Environment software suite2. The dynamic simulation was run in

Apache, with solar shading calculations carried out in SunCast, and air

exchange data from MacroFlo.

The simulation was carried out as described in Section 2, and it was

found that all regularly occupied rooms comply with the criteria set

out in the Facilities output specification (FOS) and therefore it is

unlikely the building will overheat. Full results are shown in Table 3.1
