Stawley School Community Initiative

Building Features.

1. Super-insulation :
The walls, floor and roof are intended to be super insulated well in excess of present legislation.
Goal : to reduce C02 emissions and significantly reduce running costs.

2. Thermal mass :
The central spine wall set below a south facing rooflight is to be of cobb or rammed earth to create thermal mass to soak up, store and slow release passive solar heat.
Goal : to utilise free heat from the sun to reduce major temperature fluctuations day to night. Reduces energy demand. Makes use of material that otherwise would need expensive removal from site to landfill.

3. Passive solar heating :
Orientating the building to face south and utilising large areas of glass in the south elevation, whilst minimising windows in the north elevation coupled by the use of low-emissivity timber framed triple glazing maximises heat gain useful in winter. Sun shading in the form of awnings reduces heat gain in summer.
Goal : Maximises use of free heat.

4. Energy supplied from renewable resources :
Photovoltaic / thermal array set on south facing roof used for power generation and water heating.
Goal : Pollution free power generation. Demonstration of sustainable technology at community level

5. Living Roof :
The low pitched roofs either side of the glazed corridor are to be 'green' ie planted with sedum. This reduces water run off, is environmentally friendly, helps tie the building into the landscape and reduces its visual impact. The construction adds to the roofs thermal efficiency and protects the roofs waterproof covering increasing its life.
Goal : To produce a building at ease in its setting.

6. Significant use of timber : Quick build time for lower costs, use of sustainably sourced, lower embodied energy resource as major structural element, and for external cladding, internal finishing etc.
Goal : To create a pleasant external and internal appearance using a sustainable low energy material which is easily reusable.

7. The use of high efficiency appliances :
The building includes high efficiency appliances throughout such as low flush WC's and spray taps to minimise water use. Rainwater is to be harvested for toilet flushing. A high efficiency heating system, use of solar water pre-heating and low energy lighting minimises energy req.
Goal : Significantly reduces energy and water use. Much lower bills, particularly important for low running costs and life time affordability of community buildings.

8. Waste :
During construction : The detailed design is intended to reduce construction waste During Use : Reed bed drainage system is intended to cater for sewage waste. By treating of sewage using proven natural technology a problem is turned into a teaching resource as part of a wild life habitat to the south of the building. A recycle centre for the local community is incorporated to the North of the building to encourage the philosophy of reuse for all visitors to the building.
Goal : To reduce demand on local infrastructure. To educate the community on the benefits of recycling.

9. Design : The design allows for variable use of the accommodation by arrangement creating an extremely flexible building for true community use providing facilities missing from the locality or complimenting those existing. The building is intended to be a positive statement to the community by demonstrating in its construction and design the main standards of sustainable development. The benefits will be apparent to all in the low running costs of the building
