Section – Optimum Single Sided Ventilation 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

Naturally Ventilated Building Air- Conditioned Building Annual Energy Consumption (kWh/m2) Typical Practice Project Target Annual Energy Consumption Target Setting

Typical layout of modern biomass fired boiler 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 Energy and Utilities Alternative Energy Systems

Energy and Utilities Alternative Energy Systems Biomass Boiler Plant Solar Energy – Solar Collectors 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

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

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
