Heat Recovery & Ventilation
At SJH BUILDING SERVICES, our expert knowledge of domestic and commercial heat recovery and ventilation is unparalleled.
As with all government documents, the paperwork surrounding the new Building Regulations is daunting – all 600 or so pages of it, but actually, it all boils down to two main points. First, the method of measurement shifts from elemental U-values to actual CO2 emissions. Second, all domestic buildings need to show a 25% improvement on CO2 emissions over the 2006 standard.
The 25% improvement in Dwelling Emission Rate (DER) is a step on the way towards zero-carbon houses. If that target is to be hit, then methods of ensuring that the property is built as specified have to be put in place.
Regulations are shifting more towards requiring additional information, more detail, and more calculations at the design stage. There’s also a shift towards giving Building Control Officers (BCOs) more powers to inspect and enforce. Essentially, the focus is now on designing the house properly and ensuring it is built to the design.
