Heat loss from a structure. Alternately, the amount of energy needed to generate replacement heat for that which is lost.
Energy management system
A control system (often computerized) designed to regulate the energy consumption of a building by controlling the operation of energy consuming systems, such as the heating, ventilation and air conditioning (HVAC), lighting and water heating systems.
Energy policy act (epact)
Comprehensive enrgy legislation passed by the u.S. Congress in 199(2) The lighting portion includes lamp labeling and minimum energy efficacy (lumens/watt) requirements for many commonly used incandescent and fluorescent lamps. Similar legislation is being proposed in canada.
Energy recovery ventilator (erv)
This device preheats incoming outside air during the winter and pre-cools incoming air during the summer to reduce the impact of heating and or cooling the indoor air. This means that smaller capacity heating and cooling systems can be used in homes, which results in lower installation costs, lower peak demand for energy, and lower operating costs.
Energy tax credit
Tax credit given to encourage the conservation of natural resources, as well as the development of alternative resources.
Energy-efficient window
Window that has at least two parallel panes of glass so that the loss of heat through the window is slowed.
Enforceable
An agreement, debt, judgment or law, which can be operationalized, put into effect, fulfilled, completed, executed or performed, such as a lien put upon a property upon default of a loan.
Enforcement
The legal methods used to make polluters obey the CLEAN AIR ACT. Enforcement methods include citations of polluters for violations of the law (citations are much like traffic tickets), fines and even jail terms. EPA and the state and local governments are responsible for enforcement of the Clean Air Act, but if they don't enforce the law, members of the public can sue EPA or the states to get action. Citizens can also sue violating sources, apart from any action EPA or state or local governments have taken. Before the 1990 Clean Air Act, all enforcement actions had to be handled through the courts. The 1990 Clean Air Act gave EPA authority so that, in some cases, EPA can fine violators without going to court first. The purpose of this new authority is to speed up violating sources' compliance with the law and reduce court time and cost.
Engineered 24" framing
Building framing using 24" spacing rather than the standard 16" spacing between studs.
