COMMON GREEN TERMS
Biodegradable – A material or substance which, when left exposed to nature, will decompose without harmful effects to the environment.
Certified Wood – Under the guidance of the Forest Stewardship Council (FSC), wood-based materials used in building construction that are supplied from sources that comply with sustainable forestry practices, protecting trees, wildlife habitat, streams and soil.
Daylighting – Natural daylight introduced into interior spaces and controlled specifically to reduce levels of electric lighting, minimize glare and optimize lighting quality.
Embodied Energy – All the energy used to grow, extract and manufacture a product including the amount of energy needed to transport it to the jobsite and complete the installation.
Energy Efficient – Products and systems that use less energy to perform as well or better than standard products. While some have higher up-front costs, energy-efficient products cost less to operate over their lifetime.
Energy Star® Rating – The label given by the EPA and the US Department of Energy (DOE) to appliances and products that exceed federal energy efficiency standards. This label helps consumers identify products that will save energy and money.
Environmentally Friendly – A term that refers to the degree to which a product may harm the environment, including the biosphere, soil, water and air.
GreenGuard™ – Established performance-based standards to define goods such as building materials, interior furnishings, furniture, cleaning and maintenance products, electronic equipment and personal care products with low chemical and particle emissions for use indoors.
High Performance Green Building – These buildings include design features that conserve water and energy; use space, materials and resources efficiently; minimize construction waste; and create healthy indoor environments.
Hydro chlorofluorocarbon (HCFC) – Though not without some negative environmental impacts, these substances are used to replace CFCs because they are less damaging to the ozone layer.
Indoor Air Quality (IAQ) – The supply and introduction of adequate air for ventilation and control of airborne contaminants, acceptable temperatures and relative humidity.
LEED™ – The Leadership in Energy and Environmental Design (LEED) Building Rating System sets industry standards for green building design.
Ozone Layer – Defined by the EPA as the protective layer of atmosphere, 15 miles above the ground, that absorbs some of the sun’s ultraviolet rays and reduces the amount of potentially harmful radiation reaching the Earth’s surface.
Photovoltaic (PV) – The capacity of photocells to generate electricity from the sun’s energy. PV panels are incorporated into building design.
Rapidly Renewable – Materials that are not depleted when used, but are typically harvested from fast growing sources and do not require unnecessary chemical support (example: bamboo, flax, wool).
Recyclability – The ability of a product or material to be recovered or diverted from the solid waste stream.
