As a post on this blog noted at the end of last year, the definition of zero carbon buildings is currently under consultation by the Department for Communities and Local Government.

I am in full agreement with Casey over at Carbon Limited who blogs for a call to arms on this one, this consultation is so important that all in the built environment should engage with.

The outcome definition will shape and determine design, construction, building services  and facilities management into the future, in a similar (but more profound way) that the HASAW and CDM and other milestone legislations have done.

(from zero carbon consultation:summary)

At the core of the document is the government’s preferred framework for reaching zero carbon. In order of priority:

1. A minimum standard of energy efficiency will be required.
2. A minimum carbon reduction should be achieved through a combination of energy efficiency, onsite low and zero carbon (LZC) technologies, and directly connected heat. This is referred to as achieving carbon compliance.
3. Any remaining emissions should be dealt with using allowable solutions, including offsite energy.

The zero carbon definition will have profound implications for…

… the built environment client in the choice and cost implications

… design –  a change the design parameters,

… construction, for example with airtight construction calling for a build quality and quality control we are not too good at. (Research at Leeds Met is showing that the cost of retro fixing air leaks in new buildings is  a hugely costly exercise *)

… building services – on energy sourcing and management.

And of course on the way buildings are used, run and managed.

If you haven’t read it yet, you can download it here.  or as Casey puts it – get involved or forever bitch about it in the pubs.
