Space heating systems should be designed to take account of the building heat loss and be controllable in response to the occupants’ requirements.

For well insulated, highly occupied spaces heating may only be required prior to occupancy. When the space is in use heat from occupants will maintain the temperature. In some cases cooling might be required to retain comfort conditions, even during cooler times of the year.

Alternatives to the traditional wet radiator system include underfloor heating by using pipes embedded in the floor slab which can be electric or more commonly water systems. Warm air systems which can include heat recovery from the exhaust air.

What should I do?

Ensure that fabric, occupancy and energy supply system are considered when designing the heating system and requirements.
