Performance Modeling

OVERVIEW

Thanks in part to green building programs like LEED, whole-building energy simulation has become more common. However, it’s not always doing its job.

When modeling is only used late in design, the modeling might have little value beyond keeping score. When using an iterative process of modeling early in design, results of modeling become feedback not only for the current project but also for future projects and design approaches.

Performance modeling is about more than energy. Other kinds of modeling commonly used for high-performing buildings include:

  • daylight simulation

  • hygrothermal modeling

  • thermal comfort modeling

  • climate modeling

There is no substitute, though, for understanding how your building works. These resources can help you learn how to integrate modeling strategies into your other processes.

    Innovations in product manufacturing are creating new options for designers at an ever-increasing pace. But are the new products and materials what we really want? Can we trust their claims?

  • 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.
