Using DECs to Quantify Energy Consumption in the UK Non-domestic Building Stock

Session 5 Paper 2, CIBSE Technical Symposium, Liverpool John Moores University, Liverpool
11-12 April 2013

 

This paper uses a database of 25,000 Display Energy Certificates from 2008/2009 in combination with other large-scale disaggregated data to examine the current energy performance, historic trends, and potential future improvements of UK public nondomestic buildings. High level statistical analysis has been undertaken, examining how different building, system and occupancy characteristics influence energy use, including factors beyond the scope of DECs. Much diversity was found in distinct building types and across different building characteristics, within each overall category. Where available, historic information has been used with the DEC data to explore how energy use has changed over time. Finally, the recommendations in the DEC Advisory Reports have been investigated, with a view to using them to simply estimate the emissions reduction potential from non-domestic refurbishment.
