Policy will require residential developments of 150 homes or more to calculate whole life carbon emissions through a nationally recognised Whole Life Carbon Assessment and demonstrate actions to reduce life-cycle emissions.
Principle of this Policy is not necessarily disputed, and it is supported that the First Proposals include reference to climate change.
We note in Viability Assessment that a “net zero carbon cost has been explicitly included in the appraisals” and this is welcomed. It is understood that the additional costs included allow for installation of a heat pump, mechanical ventilation with heat recovery (MVHR) and photovoltaics, with the costs allowed for as follows:
• Semi-detached house: £12,880 (10% increase on cost);
• Mid-terrace: £13,985 (13% increase on cost);
• Flats: £7,568 – based on 40 flats (5% increase on cost).
Unclear whether in all instances installation of a heat pump, mechanical ventilation with heat recovery (MVHR) and photovoltaics will be sufficient to demonstrate a net zero carbon cost as this will vary from development to development, and therefore whether sufficient cost.
