The document, called TM53: Refurbishment of non-domestic buildings, is available in print (£60) and online (£55) from the CIBSE Knowledge Portal (www.cibseknowledgeportal.co.uk).
CIBSE president George Adams commented: “With energy efficiency being critical to combating climate change and the potential energy gap, this authoritative guidance on refurbishment offered by CIBSE will support those improving performance of existing buildings which make up nearly 50% of carbon emissions.
“Making the current building stock consume significantly less energy contributes to our cities in the future to reduce their heat islands, lower carbon foot prints and lessen the demand on the already stretched energy infrastructures. Cities are key to the world’s energy problems and therefore the buildings within should strive through continuous improvement to be as energy efficient as possible and this new guide will assist in this huge challenge."
The guidance also looks at commissioning of renewable energy systems and delivery of effective natural ventilation in buildings.
