Now that we are almost upon the deadline for the introduction of zero-carbon (GLA) in London I thought that it was timely to comment on it.
Firstly. Brilliant! In a time when politicians appear to have taken leave of their senses permanently, it is reassuring that here (surrounded by the metropolitan elite) some things stay the same. We have a group of politicians willing to lead on principles rather than on the basis of prompting by tabloids or by their lesser selves. Well done London!
Secondly: Brilliant! We have a piece of zero-carbon legislation that has learned from the recent past, from multiple consultations by DCLG and the Zero Carbon Hub and run with it rather than reinventing this particular wheel. More importantly, it sets a precedent for other devolved authorities to follow. London can afford to lead on this one, to get the idea moving, to introduce developers and their design teams to the idea and to pioneer mechanisms for using the funds in a transparent and timely way so that developers can see the benefits to them.
Thirdly: There is work still to do, as there is little clear understanding about many of the aspects of the new legislation. Can we claim a credit for making improvements above regulation? For example if the team introduce dimming into the building, can they claim some CO2 reductions below the line of the regulatory calculations. If the designers use a timber structure, can they claim some embodied energy reductions? When are the payments to be made? When the building is designed, or when it is built? There are likely to be differences between the two.
I think that it would be useful if the GLA held some workshops about this new legislation and had an open discussion about these questions, to help to introduce the legislation and to hear from design teams and clients how it can work best for them and for the GLA. It is very important that this new effort succeeds, it is practically the only star left in the low-carbon buildings firmament, so let’s make sure that it burns brightly and it isn’t extinguished at the first sign of difficulty.
