Adaptive Comfort Temperatures
Savings of up to 20% heating and cooling energy can be achieved by using adaptive comfort temperatures in buildings. Comfort can also be improved.
Adaptive comfort temperatures vary in harmony with outside temperature. The variation is based on the principle that people naturally adapt to suit prevailing climate conditions (via dress, window opening, etc).
Heating may typically be set at up to 2°C below the adaptive comfort temperatures shown on the map in winter, cooling up to 2°C above in summer.
Savings of up to 50% cooling energy can be achieved by opening windows early in the day and preceding night to pre cool buildings. Peak summer temperatures can also be reduced in buildings with heating only.
The cooling introduced early on is stored in the building fabric then released later in the day when it is needed.
Predictive strategies for various locations are shown on the map to provide guidance on when to pre cool. Strategy modes are defined as follows:
Minimize ventilation "stop" - Outside too hot, too humid or too cold.
Free cool "continue" - Ventilate to maintain comfort.
Pre cool "go" - Ventilate to store cooling in building fabric.
Off - Out of hours (and no requirement to pre cool).
