More than ninety per cent of buildings are existing. How do you measure their sustainability? And how can you demonstrate improvements in an efficient manner?
BREEAM in Use (BIU) was developed to answer these questions. It is a low-threshold instrument for periodically measuring and improving the sustainability of existing properties, regardless of their age.
The method has three components:
You are not obliged to measure or certify all the components.
Dutch Green Building Council has laid down the method in an officially recognised BiU assessment guideline. This describes how the certification process works, who must do what, and what the (sustainability) requirements (=credits) are. The more credits achieved, the higher the ultimate BiU score – ranging from one to five stars, from sustainable to very sustainable. A BIU certificate is valid for three years, after which it must be applied for again.
BiU is primarily intended to be self-implementing. However, should you require support, we can provide this by:
A BiU certificate is also accepted as full evidence for real estate that is subject to an Energy Audit obligation.
