A chilled beam system may incorporate a terminal unit to provide additional heating and cooling capacity including latent cooling. In a system, terminal units may be distributed and connected to cooperate with a primary air stream from a central air handling unit. The chilled beam and/or terminal units may employ features for enhancing heating mode operation. Control embodiments take advantage of the additional capabilities described.

Various aspects as described herein are directed to a radiative cooling apparatuses and methods for cooling an object. As consistent with one or more embodiments, a radiative cooling apparatus includes an arrangement of a plurality of different material located at different depths along a depth dimension relative to the object.

A system for obtaining energy consumptions, savings and cost reduction in structures adapted for human habitation which includes the utilization of a plurality of mats including phase change material encapsulated within first and second layers of plastic material having heat transfer capability disposed within the plenum area above a ceiling of a room within a building with the amount of phase change material contained within each mat being between 0.5 lbs. and 0.67 lbs. per square foot.

Using thermal radiation to supply occupant comfort has long existed in the heating domain, and to a lesser scale in the cooling domain. Cooling power of radiant cooling systems is limited by the risk of condensation on the panel itself, as well as adjacent surfaces. Similarly, convective system losses to the ambient air prevent maintaining a large temperature difference from the surface and the surroundings. The disclosed approach combats these common pitfalls of radiant cooling systems in the building domain, increasing the power and therefore applicability of radiant cooling.
