Ventilation for Environmental Tobacco Smoke, a new book by Brian Rock, associate professor of civil, environmental and architectural engineering, explores a topic that has been on the minds of restaurant and bar owners, as well as the designers of those buildings, for years. The book discusses how to reduce odor and irritation when environmental tobacco smoke is present in a building. Designers have had little guidance on how to handle the issue, and the book serves as an introduction for those addressing environmental tobacco smoke design issues.
