The performance gap is a huge challenge, and now there is a system to verify office buildings in use - listen to how it works
Predicting energy performance at design stage is notoriously tricky - the disappointing reality is that often design and construction teams are too optimistic and once the building is occupied it turns out to be less efficient than expected.
The UKGBC has recommended that the offices sector should reduce energy demand by an average of 60% by 2050, and there are now a range of operational energy prediction methodologies available to help, including Design for Performance.
In our last jargon buster of the series, Simon Wyatt at Cundall takes on Nabers UK: the process of verifying the actual performance in use against the prediction, which also gives an office building a performance rating out of 6 stars.
Listen to this useful explanation of Nabers UK, how it borrows from Australia’s Nabers system and the lessons that are being applied in this country.
