Notes

  1. Savings values are for moderate climates similar to UK.
  2. The adaptive comfort temperatures shown on the map are for free running buildings with mainly sedentary (sitting based) activities. These are buildings where the occupant has control over themselves (eg dress) and their environment (eg window opening) - ie they have adaptive opportunity. Find out more about Adaptive Comfort Temperatures
  3. Temperature set-points should be subject to other considerations including local regulations, standards and guidance, other requirement criteria such as for equipment or artefacts, maintaining a dead band between heating and cooling systems so as to avoid conflict and energy wastage, localized thermal effects such as radiant cooling / heating close to building facades, etc
  4. A comfort band for temperature variations of +/-2°C around the comfort temperature would generally be considered acceptable. Adopting a tighter band would reduce savings while a looser band would increase savings.
  5. Window opening or opening of similar ventilation devices should be subject to other considerations including security, safety, noise, pollution, adverse weather, local discomfort, overcooling bringing on heating, fresh air requirements, etc.
  6. The predictive pre cooling strategies shown on the map are for free running buildings with moderate heat gains where the adaptive comfort temperatures are maintained by air conditioning. Strategies for other heat gain levels and buildings with heating only are provided on the Data pages.
  7. For the purposes of this website the term "air conditioning" is considered to include mechanical cooling and comfort cooling.
