The human version (we wrote this, not the council)
This policy requires new non-residential buildings of 100 square metres or more, where viable, to achieve net zero operational energy use. Space heating demand must be no more than 15 kWh per square metre a year in schools and light industrial buildings. Total energy use targets are 52 kWh per square metre a year for primary schools and 35 for unrefrigerated light industrial buildings, while other uses must disclose their energy use and keep regulated energy within 30. On-site renewable electricity must match the building's annual total energy use, and targets can be met as a site-wide average.

Policy NZ.2
Operational Net Zero in New Non-residential Buildings
Where viable new-build non-residential development of 100m2 or more shall make
the fullest possible contribution towards mitigating climate change (reducing carbon
emissions) by meeting all of the following steps.
a. The new-building shall be designed to achieve net zero operational energy
use, by meeting all of the following energy performance targets:
i. ≤ 15 kWh/m2/year space heat demand in schools and light industrial.
ii. Total energy use intensity (EUI) targets as follows:
1. ≤52 kWh/m2/year in primary schools
2. ≤35 kWh/m2/year in unrefrigerated light industrial. If unfeasible due
to the specific proposed use, then follow ‘Other’ (1.a.ii.3, below).
3. Other: Disclose total EUI in kWh/m2/year, of which the regulated-only
energy uses should be ≤30 kWh/m2/year. Show what efforts have
been made towards the relevant targets in the UK Net Zero Carbon
Buildings Standard.
4. It will be acceptable for EUI targets to be met as a site-wide average.
iii. Onsite renewable electricity annual generation kWh equal to the
building’s annual total energy use.
