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
