What is Radiant Cooling?

Radiant cooling is an energy-efficient cooling technology that, unlike traditional forced-air systems that cool the air, employs chilled radiant surfaces like ceilings or floors to directly absorb the heat radiated by objects and people within a space. Radiant cooling creates a comfortable, even distribution of coolness, without the need for visible and noisy equipment.

What is a Radiant Ceiling?

A radiant ceiling is a type of heating and cooling hydronic terminal that uses the large unobstructed surface area of the ceiling to transfer thermal energy to or from the objects in a room through thermal radiation. Radiant ceilings can be used as a standalone terminal or in conjunction with other heating and cooling systems to provide an energy-efficient and effective indoor climate solution.
