Passivhaus
Passive house () is a voluntary standard for energy efficiency in a building that reduces the building's carbon footprint. Conforming to these standards results in ultra-low energy buildings that require less energy for space heating or cooling. A similar standard, MINERGIE-P, is used in Switzerland. Standards are available for residential properties, and several office buildings, schools, kindergartens and a supermarket have also been constructed to the standard. Energy efficiency is not an attachment or supplement to architectural design, but a design process that integrates with architectural design. Although it is generally applied to new buildings, it has also been used for renovations. In 2008, estimates of the number of passive house buildings around the world ranged from 15,000 to 20,000 structures. In 2016, there were approximately 60,000 such certified structures of all types worldwide. The vast majority of passive house structures have been built in German-speaki ...

Saskatchewan Conservation House
The Saskatchewan Conservation House (211 Rink Ave, Regina, Saskatchewan, Canada) is an early exemplar of energy-efficient building construction that introduced best practices for addressing air leakage in houses. It was designed in response to the 1970s energy crisis, energy crisis of the 1970s at the request of the Government of Saskatchewan. The Saskatchewan Conservation House pioneered the use of superinsulation and airtightness in Passive house, passive design and included one of the earliest Heat recovery ventilation, heat recovery systems. The house did not require a furnace, despite prairie winter temperatures as low as at night. In 1977, when it was built at 211 Rink Avenue in the Regina Walsh Acres, Walsh Acres neighborhood of Regina, Saskatchewan, Canada, the house was the world's most airtight house. The cost of the electricity to heat the house was estimated as $30–40 for a year. The house's building envelope continues to perform as designed, more than 40 years later. ...

Passivhaus-Institut
The Passivhaus-Institut (PHI) is responsible for promoting and maintaining the Passivhaus building program. The ''"Passivhaus Institute"'' was founded in 1996, and is based and active in Darmstadt, Germany. The English spelling was used for the Passive House Institute US (PHIUS) when it formed in 2007 originally under the umbrella of the Passivhaus Institute. The two separated in 2012. Though PHI and PHIUS sustainable design standards are different, they both share common goals for drastic energy conservation and carbon reduction through sustainable architecture design techniques and specifications to create low-energy houses and other structures with low energy building practices for the public benefit worldwide.

Low-energy House
A low-energy house is characterized by an energy-efficient design and technical features which enable it to provide high living standards and comfort with low energy consumption and carbon emissions. Traditional heating and active cooling systems are absent, or their use is secondary. Low-energy buildings may be viewed as examples of sustainable architecture. Low-energy houses often have Active solar heating, active and passive solar building design and components, which reduce the house's energy consumption and minimally impact the resident's lifestyle. Throughout the world, companies and non-profit organizations provide guidelines and issue certifications to guarantee the energy performance of buildings and their processes and materials. Certifications include passive house, BBC—Bâtiment Basse Consommation—Effinergie (France), zero-carbon house (UK), and Minergie (Switzerland). Buildings alone were responsible for 38% of all human Greenhouse gas emissions (GHG) as of 2008, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superinsulation
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. Superinsulation is one of the ancestors of the passive house approach. Definition There is no universally agreed definition of superinsulation, but superinsulated buildings typically include: * Very high levels of insulation, typically R-40 (RSI-7) walls and R-60 (RSI-10.6) roof, corresponding to SI U-values of 0.15 and 0.1 W/(m2·K) respectively) * Details to ensure insulation continuity where walls meet roofs, foundations, and other walls * Airtight construction, especially around doors and windows, to prevent air infiltration pushing heat in or out * a heat recovery ventilation system to provide fresh air * No large windows facing any particular direction * Much smaller than a conventional heating system, sometimes just a small backup heater Nisson & Dutt (1985) suggest that ...

Harold Orr
Harold Walter Orr (born April 30, 1931) is a Canadian mechanical engineer known for his work on energy-efficient construction and air leakage in houses, in particular the prioritization of energy demand reduction over active systems through the use of superinsulation and airtightness in passive design. Among Orr's major technical works are ''Design and construction of low energy houses in Saskatchewan'' (1982) and ''Energy efficient housing on the prairies'' (1982). Orr worked with the Building Research Division of the National Research Council (NRC) of Canada. He focused on infiltration as a major component of heat loss. His research on air leakage in houses led to the development of the blower door, a tool still used today for tightness testing in houses. He also helped to develop the HotCan software, which continues to be used for whole house energy analysis and energy code compliance under the name HOT2000. In response to the energy crisis of the 1970s, Orr proposed radi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minergie
Minergie is a registered quality label for new and refurbished low-energy-consumption buildings. This label is mutually supported by the Swiss Confederation, the Swiss Cantons and the Principality of Liechtenstein along with Trade and Industry. The label is registered in Switzerland and around the world and is thus protected against unlicensed use. The Minergie label may only be used for buildings, services and components that actually meet the Minergie standard. Building to Minergie standards means providing high-grade, air-tight building envelopes and the continuous renewal of air in the building using an energy-efficient ventilation system. Specific energy consumption is used as the main indicator to quantify the required building quality. In this way, a reliable assessment can be assured. Only the final energy consumed is relevant. At present around 13% of new buildings and 2% of refurbishment projects are Minergie certified. These are mostly residential buildings. The goals ...

Solar Gain
Solar gain (also known as solar heat gain or passive solar gain) is the increase in thermal energy of a space, object or structure as it absorbs incident solar radiation. The amount of solar gain a space experiences is a function of the total incident solar irradiance and of the ability of any intervening material to transmit or resist the radiation. Objects struck by sunlight absorb its visible and short-wave infrared components, increase in temperature, and then re-radiate that heat at longer infrared wavelengths. Though transparent building materials such as glass allow visible light to pass through almost unimpeded, once that light is converted to long-wave infrared radiation by materials indoors, it is unable to escape back through the window since glass is opaque to those longer wavelengths. The trapped heat thus causes solar gain via a phenomenon known as the greenhouse effect. In buildings, excessive solar gain can lead to overheating within a space, but it can also be ...
