    The heat can be transferred to the surrounding air using radiators, hot water coils (hydro-air), or other heat exchangers. The radiators may be mounted on walls or installed within the floor to produce floor heat. The use of water as the heat transfer medium is known as hydronics. The heated water can also supply an auxiliary heat exchanger to ...

    en.wikipedia.org/wiki/Stack_effect

    There is a pressure difference between the outside air and the air inside the building caused by the difference in temperature between the outside air and the inside air. That pressure difference ( ΔP ) is the driving force for the stack effect and it can be calculated with the equations presented below.

    The passivhaus standard combines superinsulation with other techniques and technologies to achieve ultra-low energy use.. Superinsulation is an approach to building design, construction, and retrofitting that dramatically reduces heat loss (and gain) by using much higher insulation levels and airtightness than average.

  8. Vapour-pressure deficit - Wikipedia

    en.wikipedia.org/wiki/Vapour-pressure_deficit

    Vapour pressure-deficit, or VPD, is the difference (deficit) between the amount of moisture in the air and how much moisture the air can hold when it is saturated. Once air becomes saturated, water will condense to form clouds, dew or films of water over leaves. It is this last instance that makes VPD important for greenhouse regulation. If a ...
