Air changes per hour Air changes per hour is a measure of how many times the air within a defined space (normally a room or house) is replaced. in the past
Building envelope A building envelope is the separation between the interior and the exterior environments of a building. in the past
Domestic energy consumption Domestic energy consumption is the amount of energy that is spent on the different appliances used within housing. in the past
Fluid dynamics In physics, fluid dynamics is a subdiscipline of fluid mechanics that deals with fluid flow—the natural science of fluids (liquids and gases) in motion. in the past
Heat pump and refrigeration cycle Thermodynamic heat pump and refrigeration cycles are the models for heat pumps and refrigerators. in the past
Latent heat Latent heat is the heat released or absorbed by a chemical substance or a thermodynamic system during a process that occurs without a change in temperature. in the past
Noise control In architectural acoustics, noise control refers to the method by which interior sound reverberation is reduced. in the past
Outgassing Outgassing (sometimes called offgassing, particularly when in reference to indoor air quality) is the slow release of a gas that was trapped, frozen, absorbed or adsorbed in some material. in the past
Particulates Atmospheric particulate matter – also known as particulate matter (PM) or particulates – is microscopic solid or liquid matter suspended in the Earth's atmosphere. in the past
Psychrometrics Psychrometrics is the measurement of the heat and water vapor properties of air. in the past
Stack effect The chimney effect, also referred to as the stack effect, is the ventilation in buildings and flue gas stacks or chimneys that results from thermal differences between indoor and outside temperature as well as from the form and height of the structure which conducts the updraft. in the past
Thermal comfort Human thermal comfort is defined by ASHRAE as the state of mind that expresses satisfaction with the surrounding environment (ASHRAE Standard 55). in the past
Thermal destratification Thermal destratification is the process of mixing the internal air in a building to eliminate stratified layers and achieve temperature equalisation throughout the internal space. in the past
Thermal mass Thermal mass, in the most general sense, is any material that has the capacity to store heat. in the past
Thermodynamics Thermodynamics is the branch of physics that has to do with heat and temperature and their relation to energy and work. in the past
Vapour pressure of water The vapour pressure of water may be approximated by the following relations (in order of increasing accuracy): P = exp ( 20.386 − 5132 K T ) m m H g {\displaystyle P=\exp \left(20.386-{\frac {5132\,\mathrm {K} }{T}} in the past
