Zero Carbon House

Category: Eco-Architecture August 17th, 2007 by mbc

A term often heard, but of rarely understood, just what does it mean?

Some definitions:

“within ten years every new home will be a zero-carbon home

Gordon Brown, then Chancellor, in pre-budget report 2006.

When asked for further clarification, a zero-carbon home was defined as one that does not contribute to global warming – hardly a precise definition.

The zero carbon building produces no Carbon Dioxide and by combining all the available innovations can actually export carbon free energy back into the electricity grid.

Definitions can tend to ignore the CO2 emissions related to the sourcing of materials and the construction of the fabric of a building and in the initial provision of services and supporting infrastructure. A genuinely zero carbon building must be able to payback the carbon invested in its construction through generating and exporting zero carbon energy back into the national grid.

So where does that leave us. Personally, I am happy to use the catch-all zero carbon as an umbrella term incorporating both practical, real world low carbon design and an aspiration toward a truly zero carbon building lifecycle.

A zero carbon house is one that maintains ongoing CO2 emissions as near to zero as possible. The zero is currently aspirational.

Is the negative carbon house somewhere around the corner?

The Green Deal – update March 2012
With the Green Deal, due to be launched later this year, I thought that an update was in order since I last mentioned it back in March 2011.

The Green Deal next steps delayed
Looks like recent negative speculation over the Green Deal may be well-founded.
