The exposed concrete releases heat to, or absorbs heat from, the air passing through it. So by the time the air enters the room it is the ideal temperature for occupant satisfaction. See other Benefits of TermoDeck and find out what the 7 steps to a TermoDeck building are.
Thermal mass helps to both cool a building in the summer and keep it warm in winter:
Summer nights
At night, the air supply fans bring the cool outdoor air into the hollowcore slabs, lowering the temperature of the building. This is known as free night cooling.
Summer days
During the day, warm air that enters the building is cooled as it passes through the hollowcore slabs. The high thermal mass of the exposed ceiling soffit also absorbs internal heat gains generated from lighting, equipment, people and re-radiated solar gains.
Winter days
The heat stored by the thermal mass of the hollowcore slabs warms the fresh air from a cold winters day. Extra heat top-up may be provided by a heater unit only where necessary.
Winter nights
During the night, the system is dampered shut. The stored heat is distributed and gradually released to the internal spaces. In a lightweight building the temperature
will fall more rapidly.
