Automated Efficiency Model
An automated efficiency model (AEM) is a mathematical model that estimates a real estate property’s efficiency (in terms of energy, commuting, etc) by using details specific to the property which are available publicly and/or housing characteristics which are aggregated over a given area such as a zip code. AEMs have some similarities to an automated valuation model (AVM) in terms of concept, advantages and disadvantages. AEMs calculate specific efficiencies such as location, water, energy or solar efficiency. The Council of Multiple Listing Services defines an AEM as, “any algorithm or scoring model that estimates the fficiencyof a home without an on-site inspection. They are similar to Automated Valuation Models (AVMs), but are more reliant on public data such as square footage...and estimated energy usage.” Most AEMs calculate a property’s selected efficiency by analyzing available public information and may also apply proprietary data or formulas, and allow for a user ...

Mathematical Model
A mathematical model is an abstract and concrete, abstract description of a concrete system using mathematics, mathematical concepts and language of mathematics, language. The process of developing a mathematical model is termed ''mathematical modeling''. Mathematical models are used in applied mathematics and in the natural sciences (such as physics, biology, earth science, chemistry) and engineering disciplines (such as computer science, electrical engineering), as well as in non-physical systems such as the social sciences (such as economics, psychology, sociology, political science). It can also be taught as a subject in its own right. The use of mathematical models to solve problems in business or military operations is a large part of the field of operations research. Mathematical models are also used in music, linguistics, and philosophy (for example, intensively in analytic philosophy). A model may help to explain a system and to study the effects of different components, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Energy Information Administration
The U.S. Energy Information Administration (EIA) is a principal agency of the U.S. Federal Statistical System responsible for collecting, analyzing, and disseminating energy information to promote sound policymaking, efficient markets, and public understanding of energy and its interaction with the economy and the environment. EIA programs cover data on coal, petroleum, natural gas, electric, renewable and nuclear energy. EIA is part of the U.S. Department of Energy. Background The Department of Energy Organization Act of 1977 established EIA as the primary federal government authority on energy statistics and analysis, building upon systems and organizations first established in 1974 following the oil market disruption of 1973. EIA conducts a comprehensive data collection program that covers the full spectrum of energy sources, end uses, and energy flows; generates short- and long-term domestic and international energy projections; and performs informative energy analyses ...

Photovoltaics
Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors. A photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power. PV installations may be ground-mounted, rooftop-mounted, wall-mounted or floating. The mount may be fixed or use a solar tracker to follow the sun across the sky. Photovoltaic technology helps to mitigate climate change because it emits much less carbon dioxide than fossil fuels. Solar PV has specific advantages as an energy source: once installed, its operation does not generate any pollution or any greenhouse gas emissions; it shows scalability in respect of power needs and silicon has large availability in the Earth's crust, although other materials required ...

Energy Audit
Energy () is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, the internal energy contained within a thermodynamic system, and rest energy associated with an object's rest mass. These are not mutually exclusive. All living organisms constantly take in and release energy. The Earth's climate and ecosystems processes are drive ...

Walk Score
Walk Score, a subsidiary of Redfin, provides walkability analysis and apartment search tools. Its flagship product is a large-scale, public access walkability index that assigns a numerical walkability score to any address in the United States, United Kingdom, Canada, and Australia. Walk Score is a type of automated efficiency model focused on location efficiency. A Walk Score, as well as a Bike Score and a Transit Score, may be assigned to a particular address or an entire region, and the company maintains a ranking of the most walkable cities in the United States. Products for computer programmers include Travel Time API. Higher walk scores have been correlated with higher property values and lower mortgage default risk. The company is headquartered in Seattle, Washington. History Walk Score was founded in July 2007 by Mike Mathieu and aided by Matt Lerner, Jesse Kocher, and Josh Herst, formerly of Madrona Venture Group. In August 2010, the company launched Transit Score ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Personal Property
Personal property is property that is movable. In common law systems, personal property may also be called chattels or personalty. In civil law (legal system), civil law systems, personal property is often called movable property or movables—any property that can be moved from one location to another. Personal property can be understood in comparison to real estate, immovable property or real property (such as land and buildings). Movable property on land (larger livestock, for example) was not automatically sold with the land, it was "personal" to the owner and moved with the owner. The word ''cattle'' is the Old Norman language, Norman variant of Old French ''chatel'', chattel, and today cheptel (derived from Latin ''capitalis'', "of the head"), which was once synonymous with general movable personal property. Classifications Personal property may be classified in a variety of ways. Intangible Intangible personal property or "intangibles" refers to personal property t ...

Real Property
In English common law, real property, real estate, immovable property or, solely in the US and Canada, realty, refers to parcels of land and any associated structures which are the property of a person. For a structure (also called an Land improvement, improvement or Fixture (property law), fixture) to be considered part of the real property, it must be integrated with or affixed to the land. This includes crops, buildings, machinery, wells, dams, ponds, mines, canals, and roads. The term is historic, arising from the now-discontinued form of action, which distinguished between real property disputes and personal property disputes. Personal property, or personalty, was, and continues to be, all property that is not real property. In countries with personal ownership of real property, civil law (legal system), civil law protects the status of real property in real-estate markets, where estate agents work in the market of buying and selling real estate.
