This webinar will provide the audience with a general understanding of the principles of airflow as they relate to natural and mecha nical ventilation strategies. Topics include the effect on air flow on building geometry, thermal zoning, and placement of ape rtures and air intake/returns as well as innovative strategies. Examples of both mechanical and natural strategies and mixed mod e operation will be discussed. We will focus on the most energy efficient designs as well as relevant codes and standards. Case st udies will demonstrate how natural ventilation and mixed-mode strategies have been implemented in existing Colorado buildings. Pre requisite knowledge includes general understanding of design and construction with broad comprehension of basic principles of ene rgy efficient building design.
