The human version (we wrote this, not the council)
This section presents the net zero requirements for new homes. New residential development should achieve net zero, or where possible net negative, operational energy use. That means limiting space heating demand to 20 kWh per square metre a year and total energy use to 35 kWh per square metre a year, and providing on-site renewable electricity generation to a set formula. The renewable target can be met across a whole site, including in mixed-use schemes.

Operational Net Zero in New Residential Buildings
Where viable new-build residential development of 1 or more homes shall make the
fullest possible contribution towards mitigating climate change (reducing carbon
emissions) by meeting all of the following steps.
a. The new-build residential development shall be designed to achieve net zero,
or where possible net negative, operational energy use, through meeting all of
the following energy performance requirements:
i. ā¤ 20 kWh/m2/year space heat demand.
ii. ā¤ 35 kWh/m2/year total energy use intensity (EUI). On developments of
multiple buildings, it will be acceptable for this to be met as a site-wide
average, provided that no individual home exceeds 60kWh/m2/year.)
iii. Onsite renewable electricity generation capacity kWp equal to (ground
floor area x 60% / 4.5).
1. Or, if the kWp target is unfeasible, then provide renewable electricity
generation kWh equal to the homeās annual total energy use.
2. It is acceptable for the renewable target to be met on a site-wide
basis, including in
