The human version (we wrote this, not the council)
This policy sets climate resilient design expectations for new-build major development, meaning 10 or more homes or 1,000 square metres of floorspace. Applicants must show they have tackled overheating risk using the cooling hierarchy, which works through steps in order. The first steps are cutting internal heat from equipment, then limiting summer heat entering the building through orientation, shading, light-coloured materials, windows and insulation. Later steps manage heat inside through thermal mass, high ceilings and passive ventilation.

Policy NZ.5
Climate Resilient Design
To protect occupants from the impacts of climate change, especially in a context of
increasing energy efficiency in buildings, applications for new-build major
development (10+ homes or 1000m2 floor space) should meet the following
expectations.
1. Demonstrate that overheating risk measures have been selected in
accordance with the cooling hierarchy, where the earlier steps should be
pursued before resorting to the later steps:
a. Minimise internal heat generation through energy-efficient design and
specification
b. Minimise the amount of heat entering the building in summer, using:
i. Building orientation
ii. Shading
iii. Albedo (reflective or light-coloured external materials)
iv. Fenestration and insulation.
c. Manage heat within the building through exposed-internal thermal
mass and high ceilings.
d. Passive ventilation.
