OVERVIEW
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.
