Green Definitions

  • ANSI/ASHRAE/IESNA Standards
    American National Standards Institute (ANSI), American Society of Heating, Refrigerating and Air-Conditioning Engineers Inc. (ASHRAE), Illuminating Engineering Society of North America (IESNA) Energy Standard for Buildings. A nationally-recognized energy standard for commercial buildings.
  • Blower Door
    A test that measures the air tightness of a building.
  • Building Envelope
    The separation between the interior and exterior environment of a building. Usually consisting of the roof, doors, windows, foundation and walls.
  • Carbon Footprint
    A calculation of the amount of greenhouse gases produced as a result of commercial, industrial and individual activities.
  • Compact Fluorescent Lamp (CFL)
    Small fluorescent light bulbs that can be used in place of incandescent light bulbs. CFL’s consume significantly less electricity and last 8-10 times longer than incandescent bulbs. **These bulbs cannot be thrown away, they must be disposed of properly**
  • Energy Assessment
    A written report prepared by a qualified party evaluating energy usage, highlighting weak points in energy efficiency, and identifying cost-saving measures. A less rigorous process than an energy audit.
  • Energy Audit
    A written report prepared by a qualified tester using methods and measurements that comply with industry standards. An audit typically involves collection of detailed data and an engineering analysis. The result is a report of detailed project costs and savings expected when an energy-efficient project is completed and operated as designed.
  • Energy Efficient Mortgage (EEM)
    A mortgage that figures conserved energy into the loan in the form of credits as an energy-efficiency incentive, mostly for new homes already certified as energy efficient.
  • Energy Improvement Mortgage (EIM)
    A mortgage intended for existing homes for the purpose of installing energy efficiency improvements.
  • ENERGYSTAR
    A certification granted by the Environmental Protection Agency and the US Department of Energy for household appliances and buildings that perform at specified levels of energy efficiency.
  • Green Guides
    Guidelines published by the Federal Trade Commission (FTC) providing standards for advertising claims that a product is green.
  • Green Seal
    A certification for construction products, such as windows, paints, and adhesives, attesting that the products were manufactured and can be used with minimal impact on the environment.
  • Greenwashing
    Falsely promoting or exaggerating the greenness of a product or service.
  • Green Real Estate Designation *
    National Association of Realtors (NAR) designation designed to provide advanced training and resources to commercial and residential realtors.
  • Grey water
    Water from laundry, bathing, and similar uses that can be reused for nonpotable activities.
  • HERS, Home Energy Rating System
    A home energy rating that supplies credible verification for a home’s energy-efficiency using the home’s construction plans and the results of and onsite inspection.
  • Indoor Air Quality (IAQ)
    A measurement of the overall cleanliness of the air within a building or home.
  • LEED, Leadership in Energy and Environmental Design
    A certification granted by the United States Building Council. The detailed rating system involves full assessment of the construction, operation, and innovation of the structure including sustainability.
  • Light-Emitting Diode Lamp (LED)
    A technology that produces light by causing electrons to flow through the lamp and release energy in the form of light.
  • Net metering
    A method of gaining a credit for excess electricity produced by a consumer, often by means of a wind turbine or solar paneling.
  • On Demand Water Circulation Pump
    A water conservation device that rapidly moves water from a water heater to fixtures.
  • On Demand Water Heater
    A device that heats water rapidly as it is dispensed from the faucet. Eliminate the need for a conventional tank water heater.
  • Permeable Pavement
    A paving material that allows the penetration of water, thus significantly reducing runoff from storm water.
  • Photovoltaic
    A solar energy system that captures light from the sun and converts it into electricity.
  • VOC (volatile organic compound)
    An organic gas with harmful effects on air quality. VOC’s are frequently associated with paint, pesticides, carpet, and adhesives.
  • Xeriscaping
    A landscaping method used in arid areas. Uses native plants that can tolerate infrequent watering.
