5. Register (air and heating) - Wikipedia

   en.wikipedia.org/wiki/Register_(air_and_heating)

   During winter months, for example, an air conditioning register can be closed to prevent cold air from being pulled from the room. This allows the hot air to mix more completely with the cold air in the room, improving the efficiency of the HVAC system. [7] (The return should be efficient enough to draw off the cooler air.) [10] [11]

6. Passive cooling - Wikipedia

   en.wikipedia.org/wiki/Passive_cooling

   Passive cooling covers all natural processes and techniques of heat dissipation and modulation without the use of energy. [1] Some authors consider that minor and simple mechanical systems (e.g. pumps and economizers) can be integrated in passive cooling techniques, as long they are used to enhance the effectiveness of the natural cooling process. [7]

7. Radiant heating and cooling - Wikipedia

   en.wikipedia.org/wiki/Radiant_heating_and_cooling

   In the case of heating outdoor areas, the surrounding air is constantly moving. Relying on convection heating is in most cases impractical, the reason being that, once you heat the outside air, it will blow away with air movement. Even in a no-wind condition, the buoyancy effects will carry away the hot air. Outdoor radiant heaters allow ...
