The Department for Communities and Local Government spent the following on energy efficiency measures between 2007 and 2009:
Investment (£) 2007-08 75,000 2008-09 95,000
Investment records prior to 2007 are not readily available.
Between April 2007 and March 2009, the Department reduced gas and electricity consumption by 41 per cent. and 27 per cent. in its main building, compared to 2006-07.
Prior to implementation, all energy efficiency projects are subject to a rigorous assessment of predicted carbon reduction and financial benefits, as well as consideration of alternative solutions. Post-implementation efficacy is based upon analysis of smart meter utility data. These data are fed into the Department's Energy Efficiency Action Plan to ensure an effective and structured approach to continued carbon reduction.
To date, the majority of the efficiency measures taken across the departmental estate have been relatively low or no cost. As many of these opportunities have now been realised future measures will increasingly focus on capital investment projects, such as upgrading heating, cooling and ventilation systems.
