By 2050, around half of the total carbon dioxide emissionsÂ from the UK non-domestic sector are likely to be from buildingsÂ that were constructed before 2020.
While newbuild stockÂ constitutes only 1% of the total building stock each year, it drivesÂ thinking across the sector in terms of physical design features,Â system design and operational practices, and this thinkingÂ has an impact on refurbishment options and the operation ofÂ existing buildings.
A new report reviews the operational performance of three UK public-sector office buildings designed to achieve energy and water efficiency over the longer term, based on a study carried out in 2010â€“2012. The study, funded by BRE Trust and the Cabinet Office and the Department for Environment, Food and Rural Affairs (Defra), looked intoÂ bridging the gap between designed performance and actual operational performance over a buildingâ€™s lifetime.
This publication reports the buildingsâ€™ environmentalÂ performance (energy and water use), reviews consumptionÂ trends and concludes with a discussion of the challenges andÂ opportunities for clients and design teams to ensure thatÂ buildings are completed, handed over and operated as intendedÂ to bridge the performance gap. The results will aid propertyÂ procurers in understanding the link between predicted andÂ actual performance and help BRE to reinforce BREEAMâ€™s abilityÂ to measure issues that affect actual building performance.
