1. Albert Young – University of Glasgow Allan Crooks – Carbon Trust Case Studies

2. Glasgow Background  25,000 people, diverse buildings portfolio  Research led institution with an annual turnover of £300m  Annual utilities cost - £5m – Power prices have doubled after being fixed for 4 yrs – 50% green power - CO 2 reduced by ~ 10,000Tpa  Energy efficiency accredited

3. Carbon Trust Service Delivery  Providing support through specialist advice and consultancy services  Areas of support focused on – Design advice for capital projects 3 new buildings presented opportunities to make use of the Carbon Trust service BRE appointed as advisors to all 3 projects – Energy efficiency services in other areas Providing surveys on the built environment Identify technical solutions to carbon saving opportunities

4. Energy Efficiency Services Examples of the work done  Free Energy efficiency surveys – Identifying energy savings opportunities in space heating, lighting, controls etc  Analyses of aerial thermal image heat loss survey results – Survey of hot spot properties - loft insulation upgraded from 50mm to 150mm  Cooling of new IT server room – Free cooling - use air cooled batteries to cool the chilled water  Update of energy conservation specification – Incorporated into project briefing docs  Biomass boiler pre-feasibility  Ratification of energy conservation investments – Seeking recognition within EU-ETS for previous investments

6. Rowardennan Marine Biology Research Station  Built on the shores of Loch Lomond  Phase 1 is to replace existing facilities and provide first class research facilities  Brief to exceed environmental good practice and create a building with low running costs and low Carbon emissions  Passive energy design strategy specified for the building - narrow plan for effective daylighting, passive ventilation, selection of high thermal mass materials etc  Adopted BREEAM environmental assessments – Detailed assessment of a broad range of environmental topics

7. Design Advice Service  The Carbon Trust funded a comprehensive energy review of the design  BRE was commissioned to: – Provide advice to design team and client with regard to the options for sustainable energy sources – Complete a passive design strategy analyses Based on the stage ‘D’ report, this covered - the design intent, the site,design approach and materials. – Define a set of performance targets for the building

8. Design Advice Outcome  Options for sustainability – Micro hydro power, wind, biomass and ground source heat pump were reviewed recommending a GSHP (closed loop borehole option) – Hydro electricity investigations ongoing  Passive design strategy analyses – Confirmed that good environmental practice was being followed with regard to passive design of the building.  Assessment of environmental targets for the building – The building is set to exceed good practice by 19% and be 45% more efficient than a comparable academic building
