Low or zero carbon technologies LZC

The Home Quality Mark One, Technical Manual SD239, England, Scotland & Wales, published by BRE in 2018 suggests that low or zero carbon technologies (LZCT) provide:

‘… a source of energy generation from renewable energy sources or from a low carbon source such as combined heat and power (CHP) or a ground source heat pump (GSHP).’

A near-site LZCT is:

‘A low or zero carbon source of energy generation located near to the site of the assessed building. The source is most likely to be providing energy for all or part of a local community of buildings, including the assessed building, for example decentralised energy generation linked to a community heat network or renewable electricity sources connected via private wire.’

On-site LZCT is:

‘A low or zero carbon source of energy generation which is located on the same site as the assessed building.’
