Energy Efficiency

Energy efficiency involves a set of strategies that can be used to reduce the consumption of energy—especially fossil-fuel energy—in buildings. These strategies include:

  • monitoring energy use

  • improving building commissioning

  • applying insights from building science

  • selecting innovative HVAC and building envelope technology

  • using natural ventilation and daylighting to provide low-cost alternatives to standard systems

  • In the Pipeline: District Energy and Green Building

    Feature

    Very common in northern Europe, district energy systems use a network of buried, insulated pipes to distribute centrally produced steam, hot water, or chilled water to heat or cool multiple buildings. These systems can make use of waste heat from power generation (combined heat and power) or renewable fuel sources to help reduce the environmental impacts of buildings and communities.
