Zero carbon housingZero-carbon housing is a term used to describe a house that does not emit greenhouse gasses, specifically carbon dioxide (CO2), into the atmosphere. Homes release greenhouse gases through burning fossil fuels in order to provide heat, or even while cooking on a gas stove. A zero carbon house can be achieved by either building or renovating a home to be very energy efficient and for its energy consumption to be from non-emitting sources, for example electricity.
Environmental impact of concreteThe environmental impact of concrete, its manufacture, and its applications, are complex, driven in part by direct impacts of construction and infrastructure, as well as by CO2 emissions; between 4-8% of total global CO2 emissions come from concrete. Many depend on circumstances. A major component is cement, which has its own environmental and social impacts and contributes largely to those of concrete. The cement industry is one of the main producers of carbon dioxide, a potent greenhouse gas.
Performance énergétique des bâtimentsLa performance énergétique des bâtiments dans le cadre de la Directive pour la performance énergétique des bâtiments (PEB) () est, en Belgique, la quantité d'énergie effectivement consommée ou estimée pour répondre aux différents besoins liés à une utilisation standardisée du bâtiment, ce qui peut inclure entre autres le chauffage, l'eau chaude, le système de refroidissement, la ventilation et l'éclairage.
Healthy buildingHealthy building refers to an emerging area of interest that supports the physical, psychological, and social health and well-being of people in buildings and the built environment. Buildings can be key promoters of health and well-being since most people spend a majority of their time indoors. According to the National Human Activity Pattern Survey, Americans spend "an average of 87% of their time in enclosed buildings and about 6% of their time in enclosed vehicles.
Passive ventilationPassive ventilation is the process of supplying air to and removing air from an indoor space without using mechanical systems. It refers to the flow of external air to an indoor space as a result of pressure differences arising from natural forces. There are two types of natural ventilation occurring in buildings: wind driven ventilation and buoyancy-driven ventilation. Wind driven ventilation arises from the different pressures created by wind around a building or structure, and openings being formed on the perimeter which then permit flow through the building.
ÉcoconceptionL’écoconception est un terme désignant la volonté de concevoir des produits respectant les principes du développement durable et de l'environnement, en recourant , dans un contexte qui évoluerait alors vers une économie circulaire. La définition officielle qui fait foi pour l'ADEME est la suivante : À partir de celle-ci, on peut en effet décliner d'autres formulations ou déclinaisons.
GreeningGreening is the process of transforming living environments, and also artifacts such as a space, a lifestyle or a , into a more environmentally friendly version (i.e. 'greening your home' or 'greening your office'). The act of greening generally involves incorporating more environmentally friendly systems into one's environment, such as the home, work place, and general lifestyle. Greening is also a general term for the appropriate selection and planting of plants on, in, or next to buildings and in public parks.
Sustainable productsSustainable products are those products that provide environmental, social and economic benefits while protecting public health and environment over their whole life cycle, from the extraction of raw materials until the final disposal. According to Belz, Frank-Martin., the definition of sustainable product has six characteristics: Customer satisfaction: any products or services that do not meet customer needs will not survive in the market in a long term.
Énergie griseL’énergie grise, ou énergie intrinsèque, est la quantité d'énergie consommée lors du cycle de vie d'un matériau ou d'un produit : la production, l'extraction, la transformation, la fabrication, le transport, la mise en œuvre, l'entretien et enfin le recyclage, à l'exception notable de l'utilisation. L'énergie grise est en effet une énergie cachée, indirecte, au contraire de l'énergie liée à l'utilisation, que le consommateur connaît, ou peut connaître aisément.
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.
