IHS BRE Press Potential for Reducing Carbon Emissions From Commercial and Public-sector Buildings IP3/12

Learn about how energy use in non-domestic buildings contributes to UK carbon emissions, and the savings achievable in the commercial and public-sector building stock. This Information Paper looks at scenarios for 2012, 2017 and 2022. Author: C Pout and D MacKenzie Publish Date: 1/30/2012 ISBN: 978-1-84806-240-5 Abstract: This Information Paper summarises the contribution to UK carbon emissions of energy use in non-domestic buildings and outlines possible savings in the commercial and public-sector stock, based on the potential that existed in 2007 and looking ahead to 2012, 2017 and 2022. It will be of interest to policymakers and researchers in the field of climate change and carbon emission reductions. The non-domestic building sector accounts for around 19% of total UK carbon emissions, with most generated by energy for space heating, closely followed by lighting. The energy-saving measures considered are technologies and strategies applicable to existing buildings, and include ‘alternative’ technologies such as heat pumps and photovoltaic arrays. Interactions and overlaps between measures are also assessed. In 2007, the maximum achievable savings amounted to 25% of emissions, with 19% being saved cost-effectively. The proportion of carbon savings will fall in future years, and by 2022 the estimated maximum achievable carbon savings will account for 17% of carbon emissions, with 14% being cost-effective.
