Energy Efficiency

Our buildings consume more energy than industry or transportation, and we haven’t done a great job of reducing that consumption. We can do better by:

  • 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

As great as all these ideas are, they won’t be nearly as effective if we don’t engage occupants about energy use as well. Our articles look at all these strategies and more.

Quick Takes

Jump straight to the essentials with these short explanations of green building concepts.

  • Heat-Pump Water Heaters

    Primer

    Heat-pump water heaters produce more than twice as much hot water per kilowatt-hour of electricity consumed as standard electric water heaters.

  • The Water-Energy Connection

    Primer

    The production of electricity is highly water intense, just as the transport, heating, and cooling of water is energy intense. So saving energy saves water and saving water saves energy.

  • Tankless Water Heaters

    Primer

    Tankless water heaters have some downsides, but mostly offer advantages over conventional storage water heaters.

  • Comparing Fuel Costs

    Primer

    One would think comparing the costs of different heating fuels would be simple, but figuring out the amount heat available in a given quantity of fuel-and the associated cost-can be tricky.

  • Check if your spelling is correct, or try removing filters.
  • Remove quotes around phrases to match each word individually: "blue drop" will match less than blue drop.
  • You can require or exclude terms using + and -: big +blue drop will require a match on blue while big blue -drop will exclude results that contain drop.
