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.

  • Counting Carbon: Understanding Carbon Footprints of Buildings

    Feature Article

    Everyone seems to be talking about measuring carbon footprints and designing carbon-neutral buildings, but these terms mean different things to different people. Some focus just on operating energy, while others also look at transportation, materials, and other building-related emissions. As with so many things, the results depend on what you count and how you count it.
