MIKE’S VISION

2. MIKE’S VISION • A new multi-function teaching facility • A very special energy efficient building • A working demonstration of sustainable design An ECO CENTRE

3. Design and Construction Team • Project Manager, Civil, Structural and Building Services Engineers and Planning Supervisor WHITE YOUNG GREEN • Architect AD HOC ASSOCIATES • Quantity Surveyor JOHNSTONS • Main Contractor ROLAND HILL • Funding TEACHING ENVIRONMENTS FOR THE FUTURE GRANT

4. The Brief • Landmark building • Sustainable design • High energy efficiency using latest technology • Working demonstration of energy efficiency • Using recycled materials and alternative technology • Low embodied energy.

5. Public Consultation • Teachers • Students • Parents • Local Interest Groups and Potential External Users Outcome • Defined Building Scope • List of Potential Materials, Features and Services But • Limited Funding demanded rationalisation

6. Scope of Building • Main Teaching Space • Teaching Resource Room • Biomes • Large Entrance Lobby / Display Area • Prep Room and Stores • Office • Toilets, Kitchens and Amenities

10. Building Structure Materials Chosen • Recycled paving slab foundations • Prefabricated Timber Panel Structure • Glulam Beams • Recycled Brickwork • Prestressed Concrete First Floor • Food Barrel Plinths • Green Roof • Tyre Soakaway • Lime Mortar • Extensive insulation • Recycled Stone • Finishes made from recycled materials

11. Building Structure Materials considered but not used • Tyre Wall • Recycled Telegraph pole stub columns • Rammed earth walls • Straw walls • Limecrete • Green timber pole construction • Hemp / Lime

12. Building Services Services Chosen • Natural ventilation – electronically controlled • Underfloor heating and concrete heat sink • Ground source heat pump • Low energy, electronically controlled lighting • Wind turbine • Photovoltaic cells • Rainwater harvesting • Pond • Building Performance monitoring

13. Building Services Services considered but not used • Solar panels • Waterless Urinals • Composting Toilets • Heat Recycling • Reedbed

14. Embodied Energy • 10 – 30% of whole life energy • 10% = typical supermarket! • Improved services efficiency – high % embodied energy! • Typical Building 4 - 20 GJ / m3 • Eco Centre = 4 GJ / m3 • Embodied Energy Assessment = Mine Field!! • Productions efficiencies highly variable • Variable transport • Assessment of recycled products • Inclusion of Waste
