Centre for Disability Studies: The Peter Broughton Wing
Download
as PDF Simmonds.Mills Architects were commissioned by Disability Essex, a charity based in Essex, UK. The Centre for Disability Studies has been designed as two closely linked buildings; a North Wing, Jean Strutt House and a South Wing, The Peter Broughton Wing. The brief for the The Peter Broughton Wing called for a sustainable building that would provide lettable open plan multipurpose space for the charity to rent out to similar organisations.

Design strategies
| Planned occupancy | |
|---|---|
| Space heating strategy | 1.Extensive passive solar gain.2.Ventilation heat recovery.3.Ground brine loop and heat exchanger, forpre-heating of supply air to MVHR.4. radiators fed from small domestic (natural gas) boiler in plant room of linked building to the north.. |
| Water heating strategy | 1. taps fed from (natural gas) boiler and DHW cylinder in plant room of linked building to the north.2. Solar thermal (evacuated tubes)3. insulated hot and cold water pipework - circulating system. |
| Fuel strategy | 1. Natural gas (minimised use of)2. mains electricity |
| Renewable energy strategy | 1. Photovoltaic panels on freestanding walkway canopy. Not factored in to passivhaus certification. Forecast figure for electricity generated split between the two linked buildings. |
| Passive Solar strategy | Lots of it! |
| Space cooling strategy | 1. Passive ventilation via openable windows2. Summer bypass facility on MVHR.3. Ground brine loop and heat exchanger,for pre-cooling of supply air to MVHR.4. careful design for solar control andshading. |
| Daylighting strategy | Extensive daylighting - using extensivesouth facing high level glazing. |
| Ventilation strategy | 1. MVHR.2. Natural ventilation for night time coolingand as required |
| Airtightness strategy | Air - vapour membranes to ceilings &windows to plastered blockwork to concreteraft. Careful detailing and workmanshiparound service penetrations. |
| Strategy for minimising thermal bridges | Thermal bridge free detailing, referencingAECB CarbonLite guidance. |
| Modelling strategy | PHPP.Daylight modelling.SBEM. |
| Insulation strategy | external wall insulation approaches to walls(areas of Timber clad Larsen trusses andareas of rendered EPS EWI). Load bearingunderfloor insulation (below structural raft).Full fill blown insulation to I beamsuperstructure. Excellent thermal integritythrough careful design and workmanship. |
| Other relevant retrofit strategies | |
