• 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

• 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

Carbon Trust Review

• Carbon Trust reviewed the Colleges 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
