States that detailed information on special environmental requirements (humidity, temperature, lighting and pollution) for museums is found primarily in the art-conservation literature, with scattered references in ASHRAE publications. The HVAC system designer usually receives these design criteria from art conservators and lacks the knowledge to challenge the criteria and fully explain the various cost impacts. To assist in this, presents a survey of the latest art conservation and mechanical engineering literature.
