Elements to be considered include window placement and glazing type, thermal insulation, thermal mass, and shading. The key to designing a passive solar building is to best take advantage of the local climate. This is called passive solar design or climatic design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices. In passive solar building design, windows, walls, and floors are made to collect, store, and distribute solar energy in the form of heat in the winter and reject solar heat in the summer.

These guidelines are called the International Performance Measurement and Verification Protocol (IPMVP). The US-based organization EVO (Efficiency Valuation Organization) has created a set of guidelines for ESCOs to adhere to in evaluating the savings achieved by ECMs. This industry has been around since the 1970s and is more prevalent than ever today. īusinesses implementing ECMs in their commercial buildings often employ Energy Service Companies (ESCOs) experienced in energy performance contracting. Advanced real-time energy metering can help people save energy by their actions. īuilding technologies and smart meters can allow energy users, both commercial and residential, to visualize the impact their energy use can have in their workplaces or homes. Recent development of smartphone apps enables homeowners to complete relatively sophisticated energy audits themselves. This is normally accomplished by trained professionals and can be part of some of the national programs discussed above. An energy audit is an inspection and analysis of energy use and flows for energy conservation in a building, process, or system with an eye toward reducing energy input without negatively affecting output. One of the primary ways to improve energy conservation in buildings is to perform an energy audit. 1 Energy Conservation Opportunities by SectorĮnergy Conservation Opportunities by Sector Buildings Existing buildings.Įnergy conservation day has been celebrated on December 14 every year since 1991. It is possible to minimize these losses by adopting green engineering practices to improve the life cycle of the components. The wear and friction of the components of this machine while running cause losses of very high amounts of energy and very high related costs. However, machines are required to transform energy from one form to another. On a global level, energy use can also be reduced by the stabilization of population growth.Įnergy can only be transformed from one form to another, such as heat energy to motive power in cars, or kinetic energy of water flow to electricity in hydroelectric power plants. Įnergy can be conserved by reducing wastage and losses, improving efficiency through technological upgrades, and improved operation and maintenance. It also lowers energy costs by preventing future resource depletion. It is at the top of the sustainable energy hierarchy. Energy conservation measures (ECMs) in buildings reduce the need for energy services and can result in increased environmental quality, national security, personal financial security and higher savings. Energy conservation is a part of the concept of Eco-sufficiency. This can be achieved either by using energy more efficiently (using less energy for a constant service) or by reducing the amount of service used (for example, by driving less). For the law of physics, see Conservation of energy.Įnergy conservation is the effort made to reduce the consumption of energy by using less of an energy service.
