What industry figures want: Hywel Davies

Hywel Davies, technical director, Chartered Institute of Building Services Engineers

Our big concern is compliance. Building Control inspectors are necessarily occupied with identifying potential risks to public health and safety issues.

In response to the first question on compliance, we expressed concern for Part L, particularly how thoroughly the calculation for CO2 emissions is checked. I understand that a certificate system is under discussion stating that the calculation reflects what was actually built rather than what was ‘designed’ to be built. This introduces liability into the equation, which causes concern. But if the calculation is done properly there will be no problem, no regulatory cost and no administrative burden. We are not arguing for self-certification. Part L is complicated and designers are best placed to handle it. Building Control could then focus on clients who don’t employ experienced professionals, therefore presenting a greater risk of uncompliance.
