Including 4 closely related terms such as heating system, heating, and heating.
… indicates that significant reductions in space heating demand can be achieved at lower cost than smaller improvements, as it enables savings in the size and extent of the heating system. There is also a growing consensus on the need for total energy use as a key metric, expressed as an Energy Use Intensity (EUI). One of the key advantages is that it can be checked once the building is occupied…
… that the policy is viable across developments around the city, as discussed below. Heat Loss Form Factor The heat loss form factor, often abbreviated to ‘form factor’, is the ratio of a building’s heat loss area to its internal floor area. Contrary to small buildings which have a lot of heat loss area against a small internal floor area, large blocks of fats or high-rise blocks present a relatively…
… is very low, as expected for a large block of flats with a straightforward design. Low carbon heating The most suitable low carbon heating system is likely to be an air or ground source heat pump. To minimize distribution losses and overheating risk, the system would likely be based around a small individual heat pump in each flat, which would be supplied with water at ambient temperatures via…
