Step-by-step procedures for designing and building ventilation systems, written for artists and conservators. Part one suggests which processes might require ventilation, discusses how to detect chemical hazards and the precautions to take to decrease the cost of the ventilation system. Part two discusses basic ventilation concepts and describes types of ventilation systems, with suggestions for their maintenance. Part three gives specifications for five standard types of ventilation systems. Several useful appendices are provided, about applicable codes and regulations, sample design calculations with essential charts, a list of suppliers, a bibliography, and a glossary.
