The ‘Building Energy Efficiency’ case study series focuses on approaches to improving building performance identified in energy surveys with the target of reducing energy and carbon emissions. Each case study is designed to showcase a range of options to improve building performance, including the types of building, key issues to address for the business and challenges faced. With rising energy prices we want to give you the tools to address this challenge – improving the energy efficiency of your existing buildings is one of the key ways to reduce them.
