Zero: How low can we go?
As a result of the London Plan’s zero carbon target and the EU Nearly Zero Energy Buildings Target, our annual New Year debate, organised jointly with the AECB and Good Homes Alliance, explored the role of Passivhaus in the drive towards zero carbon.
Speakers from the GLA, Architype, HAB Housing and Levitt Bernstein made passionate arguments both for and against zero carbon, leading onto some feisty questions from the floor.
The voting results were interesting: 100% of the audience supported the GLA in adopting a target beyond the current Building Regulations Part L, and also agreed that the next version of Part L should include a fixed energy use target (kWh/m2.a); an on-site renewable energy target or an offset fund were both less popular, with approximately 10% support.
In terms of an actual target, we voted on options including; A - better than current regs but less stringent than Passivhaus; B – approximately Passivhaus; and C – Net Zero or beyond, with the audience split 25%:50%:25% for the next Part L target, and roughly 0%:60%:40% as a proposed final destination for Part L. We wonder whether that’s the way things will actually turn out?
