Taux de renouvellement horaireAir changes per hour, abbreviated ACPH or ACH, or air change rate is the number of times that the total air volume in a room or space is completely removed and replaced in an hour. If the air in the space is either uniform or perfectly mixed, air changes per hour is a measure of how many times the air within a defined space is replaced each hour. Perfectly mixed air refers to a theoretical condition where supply air is instantly and uniformly mixed with the air already present in a space, so that conditions such as age of air and concentration of pollutants are spatially uniform.
ImmotiqueL'Immotique est un néologisme formé à partir du mot immeuble et du suffixe -tique, qui connote l'informatique et l'électronique voire l'automatique etc. Comme la domotique, ce domaine est issu de la réunion de l'électronique, de l'informatique et des télécommunications. Autant que possible et théoriquement, l'immotique est un service et une somme de processus qui devraient être rendu de manière transparente ou discrète, fiable et non-intrusive pour les usagers et visiteurs d'un bâtiment.
Ventilative coolingVentilative cooling is the use of natural or mechanical ventilation to cool indoor spaces. The use of outside air reduces the cooling load and the energy consumption of these systems, while maintaining high quality indoor conditions; passive ventilative cooling may eliminate energy consumption. Ventilative cooling strategies are applied in a wide range of buildings and may even be critical to realize renovated or new high efficient buildings and zero-energy buildings (ZEBs).
American Society of Heating, Refrigerating and Air-Conditioning EngineersL'American Society of Heating, Refrigerating and Air-Conditioning Engineers (plus connue sous le sigle ASHRAE) est une organisation internationale technique dans le domaine des génies thermiques et climatiques (chauffage, ventilation, air climatisé, production de froid). Fondée en 1894, elle tient deux réunions chaque année. Elle est notamment connue pour ses publications faisant référence. Exemples de quelques standards de l’ASHRAE : Standard 34 – Designation and Safety Classification of Refrigerants ; Standard 55 – Thermal Environmental Conditions for Human Occupancy ; Standard 62.
Energy recovery ventilationEnergy recovery ventilation (ERV) is the energy recovery process in residential and commercial HVAC systems that exchanges the energy contained in normally exhausted air of a building or conditioned space, using it to treat (precondition) the incoming outdoor ventilation air. The specific equipment involved may be called an Energy Recovery Ventilator, also commonly referred to simply as an ERV. During the warmer seasons, an ERV system pre-cools and de-humidifies the intake air; during cooler seasons the system humidifies and pre-heats the incoming air.
Air ductUn air duct (ou airduct), anglicisme signifiant "Conduite d'air", est un conduit en plastique à fixer à l'intérieur de la tour (souvent sur le côté) d'un ordinateur. L'air duct permet, grâce à l'utilisation conjointe d'un ventilateur, de diriger l'air frais provenant de l'extérieur de la tour directement sur l'endroit à refroidir, sans que cet air frais ne se disperse dans l'air plus chaud de la tour. La plupart du temps, un air duct sert à diriger l'air frais sur le microprocesseur (CPU), ou plus rarement sur le processeur graphique (GPU).
Building services engineeringBuilding services engineering (BSE) is a professional engineering discipline that strives to achieve a safe and comfortable indoor environment whilst minimizing the environmental impact of a building. Alternative titles are "mechanical, electrical and plumbing" (MEP) engineering, "technical building services", "building engineering" or "facilities and services planning engineering". The term BSE is widely used in Commonwealth countries (incl.
Building scienceBuilding science is the science and technology-driven collection of knowledge in order to provide better indoor environmental quality (IEQ), energy-efficient built environments, and occupant comfort and satisfaction. Building physics, architectural science, and applied physics are terms used for the knowledge domain that overlaps with building science. In building science, the methods used in natural and hard sciences are widely applied, which may include controlled and quasi-experiments, randomized control, physical measurements, remote sensing, and simulations.
Radiant heating and coolingRadiant heating and cooling is a category of HVAC technologies that exchange heat by both convection and radiation with the environments they are designed to heat or cool. There are many subcategories of radiant heating and cooling, including: "radiant ceiling panels", "embedded surface systems", "thermally active building systems", and infrared heaters.
