Main issues, as the Inspector framed them
- Whether the disputed condition limiting use of air source heat pump active cooling is necessary and reasonable, having regard to development plan policies which seek to mitigate and adapt to climate change
What decided it
The updated thermal modelling analysis provided adequate demonstration that the cooling hierarchy had been applied and identified the specific rooms requiring active cooling, making it necessary and reasonable to amend the condition to permit cooling only in those demonstrated rooms rather than prohibit it entirely.
The requirement to mitigate climate change through limiting active cooling was balanced against the practical necessity to provide cooling in specific rooms where thermal modelling demonstrated it was required to meet thermal comfort standards, with the balance struck by permitting active cooling only in those identified rooms
What the Inspector cited
- Development plan policies
- Policy D1 of the 2017 Camden Local PlanPolicy CC1 of the 2017 Camden Local PlanPolicy CC2 of the 2017 Camden Local Plan
