The Canada-France-Hawaii-Telescope is in the process of upgrading the primary mirror cell for cooling of the mirror during non-operating hours. This paper addresses the goals of CFHT in insulating and actively cooling the primary mirror cell environment. The main design criteria is to have a system that would introduce chilled dry air to a sealed and insulated primary mirror cell during daylight hours. This could remove the deleterious effects of having the primary mirror warmer than the ambient air. A system is planned to protect the mirror in case of sudden moisture exposure and also decrease the frequency of recoating due to contamination.
