From 2009 companies and other organisations, will be required to report to the Environment Agency details of their energy usage, from almost all sources, on an annual basis.

1. Sustainable Buildings Tim Pollard

3. What is sustainable development? Economic Environmental Social Sustainable Development Source: CPA

4. Non Domestic Buildings It is estimated that 60% of the buildings that will be standing in 2050 have already been built Carbon emissions from energy use in non-domestic buildings account for around 18% of total emissions 70% of non-domestic buildings pre-date Part L (1985) 40% of buildings in 2050 will pre-date Part L (1985) New build represents 1-2% of floor space in any 1 year

5. UK Carbon Emissions by Sector

7. Principal Strategies Most organisations find that a hefty 20-40% of their electricity costs come from lighting. Yet you can cut these costs by up to a third while reducing your carbon footprint and improving the working environment Most manufacturing companies can make significant carbon savings in processes and service companies can save on often save on ICT Efficient buildings and plant will count for little if we still tolerate wasteful behaviours Maximising the efficiency of the building envelope and using insulants, natural light and air can make major contributions Carbon Reduction Heating and hot water can account for 60% of total energy costs In a typical office, air conditioning can account for over 30% of annual electricity consumption Fabric Heating/ Cooling Lighting Process Behaviour

8. Fabric The more ‘efficient’ the building, the less energy used Insulants Interior Insulants Exterior Glazing Entrances and Exits Air Tightness Cold Bridging

9. Heating & Power When energy use is unavoidable try to use renewable sources & improve system efficiency Renewables Solar thermal Ground Source Heatpumps Air Source Heatpumps Biomass Combined Heat and Power Photovoltaics Other Controls Variable Speed Pumps & Drives Energy Efficient Boilers

12. Lighting - LED A typical retail environment, of 350 sq m, with 84 luminaires operating for an average of 70 hours a week. A standard 2x26W compact fluorescent (CFL) luminaire uses 17,428 Kwh per year. Using the axent RXD, the annual Kwh consumption is 11,313. The saving amounts to 6,115Kwh – or 35% A typical school or college, at 1,600 sq m, operating 400 luminaires for 55 hours a week. Traditionally, using 2x26W CFL, the annual Kwh consumption is 65,208. Using RXD, the annual Kwh stands at 42,328 – a saving of 35%. Retail Education

15. Lighting Measures MEASURE % Savings Localised instead of general lighting 60-80 Replace bulkhead tungsten GLS lamps with CFL versions 40-70 High frequency ballasts for fluorescent lamps 15-20 Replace old fluorescents with hf T5 20-25 Lighting Controls 20-50 Replace tungsten spotlights with tungsten halogen 30-75 Consider LEDs 35-75

16. Other Benefits Include Reduced cost of operating with lower energy use Reduced risks due to future energy cost and supply uncertainty Better comfort, satisfaction and productivity for occupants Recruiting and retaining quality staff by demonstrating corporate responsibility Sales and marketing benefits from demonstrating a commitment to reducing carbon emissions

20. 3 Whitehall Place (Department of Energy & Climate Change) Government officials have officially confirmed that of almost 9,000 public buildings given DEC ratings last year, over 75% scored a D or lower rating. G
