16. 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

19. 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

20. 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

21. 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

22. 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
