Mr. Seán Armstrong:

Exhaust air heat pumps. They take the ventilation air and recover the heat from it.

At present, the energy performance of buildings directive sets a five-year timeline for the review of building regulations. To do it any more quickly would be too quick. Many developments take between a year and a half and two years to develop. To start changing the goalposts in the middle of that design would be unfair and would cause problems for the construction industry. The important thing is that we keep advancing our performance requirements and set realistic but ambitious targets for the industry to achieve. They must be able to achieve them but they must also be ambitious in order to meet our climate action goals.

There was a question about stoves, I think it related to social housing?
