Building Airtightness
Building airtightness (also called envelope airtightness) can be defined as the resistance to inward or outward air leakage through unintentional leakage points or areas in the building envelope. This air leakage is driven by differential pressures across the building envelope due to the combined effects of stack, external wind and mechanical ventilation systems. Airtightness is the fundamental building property that impacts infiltration and exfiltration (the uncontrolled inward and outward leakage of outdoor air through cracks, interstices or other unintentional openings of a building, caused by pressure effects of the wind and/or stack effect).M. Limb, "Technical note AIVC 36- Air Infiltration and Ventilation Glossary," International Energy Agency energy conservation in buildings and community systems programme, 1992 An airtight building has several positive impacts when combined with an appropriate ventilation system (whether natural, mechanical, or hybrid): * Lower heating bi ...

Ductwork Airtightness
Ductwork airtightness can be defined as the resistance to inward or outward air leakage through the ductwork envelope (or ductwork shell). This air leakage is driven by differential pressures across the ductwork envelope due to the combined effects of stack and fan operation (in case of a mechanical ventilation system). For a given HVAC system, the term ductwork refers to the set of ducts and fittings (tees, reducers, bends, etc.) that are used to supply the air to or extract the air from the conditioned spaces. It does not include components such as air handlers, heat recovery units, air terminal devices, coils. However, attenuators, dampers, access panels, etc. are a part of the ductwork even if they have more functions than conveying the air and are therefore also referred to as technical ductwork products. Ductwork airtightness is the fundamental ductwork property that impacts the uncontrolled leakage of air through duct leaks. Metrics There are two major systems to classify ...

Directive On The Energy Performance Of Buildings
The Energy Performance of Buildings Directive (EPBD) is the European Union's main legislative instrument aiming to promote the improvement of the energy performance of buildings within the European Union. It was inspired by the Kyoto Protocol which commits the EU and all its parties by setting binding emission reduction targets. In 2021, the European Commission proposed to review the directive, with a view of introducing more exigent energy efficiency minimum standards for new and existing buildings, improved availability of energy performance certificates by means of public online databases, and to introduce financial mechanisms to incentivize banks to provide loans for energy efficient renovations. History Directive 2002/91/EC The first version of the EPBD, directive 2002/91/EC, was approved on 16 December 2002 and entered into force on 4 January 2003.European Commission,DIRECTIVE 2002/91/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 16 December 2002 on the energy p ...

Soudal
Soudal is a Belgian company whose headquarters is located in Turnhout (Belgium). The company has developed into one of the most important independent producers of silicone and caulks (silicone, polyurethane, marine sealants, acrylics), polyurethane-foams, and adhesives in Europe. Soudal has a consolidated turnover of 911 million EUR (2021), and the company distributes its products to more than 140 different countries worldwide. The company is active in three markets: professional construction, do-it-yourself (DIY) hardware stores and industrial applications. The company is still fully owned by Vic Swerts who founded the company in 1966. In 2014, Soudal partnered with Lotto to sponsor the team at Tour de France. In April 2020, Riders for the Lotto-Soudal team voluntarily waived part of their wages as a gesture of solidarity due to the Covid-19 pandemic. History In 1966, Vic Swerts bought a small producer of welding materials and of polyester putties for the repair of damage ...

Air Infiltration And Ventilation Centre
Air Infiltration and Ventilation Centre (AIVC) is the International Energy Agency information centre on energy efficient ventilation of buildings. History The AIVC started in 1979 in the context of the first and second oil crisis in 1973 oil crisis, 1973 and 1979 oil crisis, 1979. The Centre was established as the 5th research project (Annex 5) in the context of the implementing agreement Energy in Buildings and Communities Programme (at that time called ECBCS) of the International Energy Agency. Since its inauguration, in 1979, the AIVC has been running without interruption. In November, 2020 the executive committee of the International Energy Agency Technical Collaboration Programme Buildings and Communities, approved a 5-year extension period for the AIVC from 2022 till 2026. In the first years, the AIVC's primary focus was understanding and finding ways to limit the energy impact of air infiltration in buildings.P.

Heating, Ventilation, And Air Conditioning
Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation as HVAC&R or HVACR, or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers). HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels, and senior living facilities; medium to large industrial and office buildings such as skyscrapers and hospitals; vehicles such as cars, trains, airplanes, ships and submarines; and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh ai ...

Energy Conservation
Energy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively (using less energy for continuous service) or changing one's behavior to use less service (for example, by driving less). Energy conservation can be achieved through energy efficiency, which has a number of advantages, including a reduction in greenhouse gas emissions, a smaller carbon footprint, and cost, water, and energy savings. Energy conservation is an essential factor in building design and construction. It has increased in importance since the 1970s, as 40% of energy use in the U.S. is in buildings. Recently, concern over the effects of climate change and global warming has emphasized the importance of energy conservation. Energy can only be transformed from one form to another, such as when heat energy is converted into vehicle motive power or when water flow's kinetic energy is converted into electricity in hydroelectr ...
