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.

Full-Blown Energy Modeling
Webcast
Like any tool, energy modeling needs to be wielded properly. Savvy designers know that different kinds of models are useful at different times. For example, if you use a calibrated energy model only at the end of the design process, you’re not only misusing this particular technique—you’re also missing out on the dollar and energy savings this type of modeling can provide. This one-hour webcast will show you how to save thousands of dollars in first costs and operational costs.
