Energy Efficiency

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.

    Blog Post

    The concept of the net zero energy (NZE) is a mature one, with established technology providing a clear path, especially for low- and mid-rise buildings.

  • 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.

  • Energy Modeling for Early Design Decisions

    Webcast

    Thanks in part to green building programs and codes, whole-building energy simulation has become more common over the last two decades — but all too frequently, modeling is only used late in design, when it has little value beyond keeping score. If you're not using modeling to make design decisions from the outset, not only are you missing out on hundreds of thousands of dollars in energy savings — you're wasting the thousands of dollars that go into the model, as well as first cost savings. In this webcast, BuildingGreen hosts a group of the world's top energy modeling experts to demystify the steps that leading firms are taking to incorporate modeling into early design decisions, cost-effectively.
