Value of green building construction projected to what amount in 2010?
60$ Billion
Acid Rain
the precipitation of dilute solutions of strong mineral acids, formed by the mixing in the atmosphere of various industrial pollutants (primarily sulfur dioxide and nitrogen oxides) with naturally occurring oxygen and water vapor.
Adapted plants
nonnative, introduced plants htat reliably grow well ina given habitat with minimal winter protection, pest control, fertilization, or irrigation once their root systems are established. Adapted plants are considered low maintenance and not invasive.
Air quality standards
The level of pollutants prescribed by regulations that is not to be exceeded during a given time in a defined area.
Alternative fuel vehicles
Vehicles that use low-polluting, nongasoline fuels, such as electricity, hydrogen, propane or compressed natural gas, liquid natural gas, methanol. and ethanol. In LEED, efficient gas-electric hybrid vehicles are included in this group.
Ambient temperature
The temperature of the surrounding air or other medium.
American Society of Heating, Refrigerating and Air-Conditioning Engineers.
A process used to remove volatile organic compounds (VOCs) from a building by elevating the temperature in the fully furnished and ventilated building prior to human occupancy.
Capable of decomposing under natural conditions.
The variety of life in all forms,levels, and combinations, including ecosystem diversity, species diversity, and genetic diversity.
Plant material from trees, grasses, or crops that con be converted to heat energy to produce electricity.
A stormwater control feature that uses a combination of an engineered basin, soils, and vegetation to slow and detain stormwater, increase groundwater recharge, and reduce peak stormwater runoff.
Wastewater from toilets and urinals; definitions vary, and wastewater from kitchen sinks(perhaps differentiated by the use of a garbage disposal), showers, or bathtubs is considered blackwater under some state or local codes.
British thermal unit(Btu)
the amount of heat required to raise the temperature of one pound of liquid water from 60 degrees to 61 Fahrenheit. This standard measure of energy is used to describe the energy content of fuels and compare energy use.
Real property whose use may be complicated by the presence or possible presence of a hazardous substance,pollutant, or contaminate.
Building Density
The Floor area of the building divided by the total area of the site (square feet per acre).
Building Envelope
the exterior surface of a building-the walls,windows, roof, and floor;also referred to as the bulding shell.
Building Footprint
The area on a project site that is used by the building structure, defined by the perimeter of the building plan. Parking lots, landscapes, and other nonbuilding facilities are not included in the building footprint.
Material, other than the principal product, generated as a consequence of an industrial process or as a breakdown product in a living system.
