Table of ContentsDesigning buildings for both high indoor air quality and energy efficiency requires an integrated design approach.

There is a movement in the commercial real estate industry to pay more attention to the issue of indoor air quality (IAQ) throughout the design and construction stages of a building's life.

The "Green Design" movement also places emphasis on IAQ. This Design Brief defines indoor air quality, discusses ventilation as a method of maintaining high IAQ, and introduces demand controlled ventilation (DCV).

With increasing concerns about electricity demand in California, 2001 Title 24 Standards require that DCV strategies be employed in high-density areas (occupant density of more than one person per 10 square feet).

The brief ends with a discussion of seven ways to ensure that a building's indoor air quality strategy is both energy-efficient and health-inducing.

The first edition of this design brief was prepared for Energy Design Resources in 2003. Between January and April of 2010, an engineering review of this document was conducted to update passages affected by recent changes in the California Building Energy Efficiency Standards (Title 24 2008). The original content creator was not actively involved in this engineering review, and therefore is not responsible for the updates to the affected passages.
