  1. 14 July 2009 JOHN WHEATLEY COLLEGE EAST END CAMPUS

  2. Figure 5.7

  3. John Wheatley College East End Campus A High Quality BREEAM Excellent Public Building with Environmental and Sustainable Features (6,459 sq m) Built within Budget – Handover 9 March 2007 and Operational 12 March 2007

  4. Environmental and Sustainable Features • Rainwater Harvesting and Recycling • Biomass Boiler • Photo-Voltaic Cells • Solar Collectors • Air Sourced Heat Pumps • ETFE Roof • Higher than Required Thermal Insulation • Lighting Control Systems • Passive Ventilation

  5. Delivery Team Project Manager – Capita Symonds Ltd Cost Consultant – Doig & Smith Architect – Aherns Burton and Koralek Mechanical, Electrical, Structural and Civil Engineers – Buro Happold Environmental Consultant – Ironside Farrah Contractor – HBG (now BAM) Construction Ltd

  6. Costs Project Cost £15m Building Contract £9.1m FF&E £800k Building Cost £1,409 per sq m Project Cost £2,183 per sq m Sustainable Features - 3.11% of Project Cost Structural Funds (ERDF) £2,818,47919% of Project Cost

  7. Sunpath Diagram Prevailing Winds Street noise and pollution The site is very exposed on the South and East aspects Site Environmental Microclimate

  8. Sunpath Diagram Prevailing Winds The site is very exposed on the South and East aspects Site Environmental Microclimate

  9. Double Glazing • For South Façade light transmittence of 0.6 or less or 1m overhang • Low “E” coating to reduce heat loss • Top and bottom opening lights preferable (minimum 125mm) • Trickle vent to frame • High performance seals Site Environmental Microclimate Section – Optimum Single Sided Ventilation

  10. Project Target 600 500 Annual Energy Consumption (kWh/m2) Typical Practice 400 300 200 100 0 Air-Conditioned Building Naturally Ventilated Building Annual Energy Consumption Target Setting

  11. A biomass boiler uses waste material or renewable sources e.g. refuse, wood, crops etc to generate useful heat • Recommendation for a 100 kW heat-only system to be developed to meet the year round base load for the entire site • Woodchip fuel source from off-cuts from the forestry commission • 100kW biomass boiler = 0.35GWh of carbon free energy per year for the John Wheatley College Typical layout of modern biomass fired boiler Energy and Utilities Alternative Energy Systems

  12. Rainwater to Grey Water Rainwater Break Tank Urinal WC WC Cartridge Filter + UV Solar Powered Pump Irrigation Rainwater Retention Tank Grey Water Retention Tank Water Conservation

  13. Roof mounted solar collectors Exposed concrete soffits Good window design Site Environmental Microclimate Section - materials

  14. Biomass Boiler Plant • Biomass Boiler Unit • Rainwater and Grey Water Recycling • Solar collectors for domestic hot water • Rainwater and Grey Water Recycling • PIR control of: • Lighting • Security • Waste recycling Solar Energy – Solar Collectors Energy and Utilities Alternative Energy Systems

  15. Carbon Trust Review • Carbon Trust reviewed the College’s renewable energy elements and sustainable features • Concluded the College had an efficient mix of renewable energy and other sustainable features • Carbon Trust estimated largest saving and shortest payback from rainwater recycling

  16. Post Occupancy Evaluation • Now mandatory on new build projects • SFC funded project with Cumbernauld, Carnegie, John Wheatley and Queen Margaret University • Functional Performance Review • Independent BREEAM Assessor appointed early • Future building occupants consulted early

  17. Specify detail • Consider secondary effects of equipment • Develop a user guide for staff • Train staff in building systems • Record and monitor utility usage • Use energy saving equipment • Maintain the building

  18. Sustainable Accounting • Pilot project • Energy Consumption • Water Usage • Materials and Product Consumption • Waste Generation and Disposal • Travel and Transport • Other Sustainability Initiatives
