OVERVIEW

There are three primary reasons to design a building for natural ventilation.

  • Energy savings can be dramatic.

  • Occupant satisfaction is usually very high.

  • Indoor air quality is significantly better.

So why isn’t natural ventilation just a given in every design? It usually has more to do with perception than with physics.

Here you’ll find an in-depth look at the benefits of and barriers to natural ventilation as well as strategies for smart design.

    Webcast

    While airflow analysis isn't part of most building simulations today, it is part of nearly all low-energy buildings. Unfortunately, many architects aren't well-positioned to take advantage of this opportunity because they aren't trained to set up or interpret most airflow models. This webcast will introduce you to new software that enables you to engage more fully with airflow investigations required to validate design strategies.
