Including the closely related terms insulation, and insulation.
… in their recent response to the Future Homes Consultation. Changes include modest improvements to insulation, shower drain wastewater heat recovery and roof mounted solar PV. While heating is still based on a gas boiler, it is possible that developers could use heat pumps instead of wastewater heat recovery and solar PV to achieve the required performance. Airtightness is relatively poor at 5m3/m2hr…
… and ventilation is achieved mechanically without heat recovery. Part L 2025 This scenario is also based on an additional notional building specification provided by the government in their response to the Future Homes Standard Consultation. Insulation levels and glazing performance are increased close to that required for Passivhaus, however airtightness remains poor at 5m3/m2hr and no heat recovery…
… low heat loss area when compared to their internal floor area, and have low form factors, typically below 2.5. As a result, they naturally have lower levels of heat loss and therefore require less insulation to comply with the policy scenarios. Potential for Solar PV On the other hand, the ratio of suitable roof area for solar PV panels is quite small. High-rise blocks of flats have internal…
