Zero Heating Building
Zero-heating building or nearly zero-heating building (nZHB) is a building having essentially zero heating demand, defined as having heating demand, Q’NH, less than 3 kWh/(m2a). The zero-heating building is intended for use in heating-dominated areas. The purpose of the zero-heating building is to supersede Zero-energy building, net-zero energy buildings as a way to bring building-related greenhouse gas emissions to zero in the EU. Zero-heating buildings address flawed net-zero energy buildings: the requirement for seasonal energy storage, in some cases poor comfort of living and narrow design options. Concept and approach Seasonal energy storage problem In areas where there is substantial heating demand, it is hard to fill this demand with Renewable energy, renewable power as in heating season, solar power is in short supply. This means heating in highly urbanized areas is directly or indirectly powered by, in a large part from fossil sources. About 2000 TWh of seasonal ener ...

Zero-energy Building
A Zero-Energy Building (ZEB), also known as a Net Zero-Energy (NZE) building, is a building with net zero energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site or in other definitions by renewable energy sources offsite, using technology such as heat pumps, high efficiency windows and insulation, and solar panels. The goal is that these buildings contribute less overall greenhouse gas to the atmosphere during operation than similar non-ZNE buildings. They do at times consume non-renewable energy and produce greenhouse gases, but at other times reduce energy consumption and greenhouse gas production elsewhere by the same amount. The development of zero-energy buildings is encouraged by the desire to have less of an impact on the environment, and their expansion is encouraged by tax breaks and savings on energy costs which make zero-energy buildings financially viable.

Zero Carbon Housing
Zero-carbon housing is housing that does not emit greenhouse gasses (GHGs) into the atmosphere, either directly ( Scope 1), or indirectly due to consumption electricity produced using fossil fuels ( Scope 2). Most commonly zero-carbon housing is taken to mean zero emissions of carbon dioxide, which is the main climate pollutant from homes, although fugitive methane may also be emitted from natural gas pipes and appliances. Definition There are nevertheless a number of definitions of zero carbon housing, particularly concerning the scope of emissions in the housing lifecycle (eg construction vs operation or refurb), and whether it is acceptable to count off-site emissions reduction (eg due to renewable energy export) or other external reductions against any residual emissions from the house to make it a Net Zero Home. The Chancery Lane legal climate project gives 6 definitions of zero carbon housing or buildings, of which 2 explicitly allow for the inclusion of off-site emiss ...

Building Insulation
Building insulation is material used in a building (specifically the building envelope) to reduce the flow of thermal energy. While the majority of insulation in buildings is for thermal insulation, thermal purposes, the term also applies to acoustic insulation, Fireproofing, fire insulation, and Cushioning, impact insulation (e.g. for vibrations caused by industrial applications). Often an Building insulation materials, insulation material will be chosen for its ability to perform several of these functions at once. Since prehistoric times, humans have created thermal insulation with materials such as animal fur and plants. With the agricultural development, earth, stone, and cave shelters arose. In the 19th century, people started to produce insulated panels and other artificial materials. Now, insulation is divided into two main categories: bulk insulation and reflective insulation. Buildings typically use a combination. Insulation is an important economic and environmenta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Passive Solar Building Design
The passive solar design of buildings includes consideration of their orientation to the sun and their thermal mass, factors which have been incorporated to a greater or lesser extent in vernacular architecture for thousands of years. Ancient Greeks, Romans, and Chinese were the first to refine and develop the basic principles of passive solar design, but European technological advances were largely abandoned after the Fall of Rome. It was not until the 20th century that interest in the principles of passive solar design had a resurgence in Europe and the U.S.A., with architects such as George F. Keck and Frank Lloyd Wright. In the 21st century, worldwide endeavours to reduce power consumption have kept the interest in passive solar technology alive. Pre-modern history The techniques of passive solar building design were practiced for thousands of years, by necessity, before the advent of mechanical heating and cooling. It has remained a traditional part of vernacular architecture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold Downdraught Analysis Multipane Glazing
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjectivity, subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical physics, classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy ...

Indoor Air Quality
Indoor air quality (IAQ) is the air quality within buildings and Nonbuilding structure, structures. Poor indoor air quality due to indoor air pollution is known to affect the health, comfort, and well-being of building occupants. It has also been linked to Sick Building Syndrome, sick building syndrome, respiratory issues, reduced productivity, and impaired learning in schools. Common pollutants of indoor air include: Passive smoking, secondhand tobacco smoke, Household air pollution, air pollutants from indoor combustion, radon, Mold health issues, molds and other allergens, carbon monoxide, volatile organic compounds, legionella and other bacteria, Asbestos, asbestos fibers, carbon dioxide, ozone and Atmospheric particulate matter, particulates. Source control, filtration, and the use of ventilation (architecture), ventilation to dilute contaminants are the primary methods for improving indoor air quality. Although ventilation is an integral component of maintaining good indoo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Product Differentiation
In economics and marketing, product differentiation (or simply differentiation) is the process of distinguishing a product or service from others to make it more attractive to a particular target market. This involves differentiating it from competitors' products as well as from a firm's other products. The concept was proposed by Edward Chamberlin in his 1933 book, '' The Theory of Monopolistic Competition''. Rationale Firms have different resource endowments that enable them to construct specific competitive advantages over competitors. Resource endowments allow firms to be different, which reduces competition and makes it possible to reach new segments of the market. Thus, differentiation is the process of distinguishing the differences of a product or offering from others, to make it more attractive to a particular target market. Although research in a niche market may result in changing a product in order to improve differentiation, the changes themselves are not ...

Insulated Glazing
Insulating glass (IG) consists of two or more glass window panes separated by a space to reduce heat transfer across a part of the building envelope. A window with insulating glass is commonly known as double glazing or a double-paned window, triple glazing or a triple-paned window, or quadruple glazing or a quadruple-paned window, depending upon how many panes of glass are used in its construction. Insulating glass units (IGUs) are typically manufactured with glass in thicknesses from . Thicker glass is used in special applications. Laminated or tempered glass may also be used as part of the construction. Most units are produced with the same thickness of glass on both panes but special applications such as acoustic attenuation or security may require different thicknesses of glass to be incorporated in a unit. The space in between the panes provides the bulk of the insulation effect. It can be filled with air, but argon is often used as it gives far superior insulation, ...

Passive House
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-speak ...
