2 Shift in DEC distribution from

3 Carbon Trust Report Non-domestic buildings responsible for 18% of total UK carbon emissions 35% CO 2 reduction by 2020 with a net benefit to the UK of at least 4bn This will involve the vast majority of buildings undergoing some level of improvement Most of the opportunity utilises simple low cost measures such as lighting and heating controls, or better management and building use behaviours

4 Setting a baseline for environmental performance

5 BREEAM In-Use BREEAM In-Use is a new scheme to help building owners and occupiers to reduce the environmental performance and running costs of existing buildings. It consists of: a standard An easy-to-use assessment methodology and a 3rd party certification process Providing a clear and credible route map to improving sustainability

6 Scope of Asset & Management questions Asset Management Energy Water Transport EPC rating, lighting & control, cooling system, sub-metering Water meters, low water using WCs, auto leak detection Close proximity to public transport, adequate cycle racks & showers DEC rating, annual energy use, trained building managers Annual water consumption Staff travel surveys, green travel initiatives, home working policy Waste Space for recycling waste Waste management plans, quantity of waste disposed, waste targets Management Environmental management system, staff training, environmental purchasing Ecology Green roofs, bat boxes Ecological survey of site Health & wellbeing Materials Pollution Staff control of temp & ventilation, glare control features Maintenance policy in place, approved alarm systems Flood risk, SUDs systems, refrigerants with ozone depletion potential Minimise use of VOCs, low solvent cleaning, occupant satisfaction surveys Reduce use of hazardous materials, enviro risks of fire incidents Policy for reducing surface water runoff, survey for land contamination

11 Cost-effective energy efficiency measures

12 Voltage Optimisation Reduce electricity costs and carbon emissions by 10 to 15%, Improves power quality to site 10 year guarantee and a year life cycle 24/7 operation and NO maintenance 2-4 year paybacks Unit 350 kva Optimisation 8% kwh Savings 14.3% Savings p.a. 2,500 CO2 Savings p.a. 16,000kg

15 Microgeneration Technologies

16 Microgeneration Technologies Heat pumps Solar thermal hot water Wood-fuelled boilers Pellet stoves Wind turbines Micro-hydro turbine Solar photovoltaic (PV)

17 The Funding Mosiac Rapidly changing: currently includes: Low Carbon Buildings Programme capital grants for local authorities & not for profit organisations Community Sustainable Energy Programme capital and project development grants Feed-In Tariffs for electricity generating technologies from March 2010 Renewable Heat Incentive from April 2011

18 Behavioural change

19 Human management was at least as important as technology in securing good energy performance There is evidence in the building studies that both productivity and energy efficiency are improved by the provision of some degree of individual control...brownhill (1999) Keep the design simple Automation is not always the answer Give occupants control or at least the FM Ensure systems are fully commissioned (15% energy saving, payback < 8 months) Ensure adequate and appropriate training for all building occupants
