To preserve both the cultural collections and the historical buildings that house them, a technologically simple yet robust climate control system was installed in two small rooms containing the Historic Archive of the Canary Islands, located in a municipal building of the city of La Laguna on Tenerife Island, Spain. The building is a late 19th century massive masonry building located in a sub-tropical climate site. The system was designed to maintain the RH level (less than 75%) necessary for preventing microbial activities in collections in cultural institutions by operating residential-type ventilators and a heater under a humidistatic control. Interior and exterior climates as well as interior levels of microbial activities and dust deposition were monitored, before and after the installation of the systems. After nearly one year of operation, we have confirmed that the system not only successfully eliminated events of high RH but also stabilized it. The annual temperature variation was significantly reduced, although daily variations increased. The room's moisture content was reduced to less than that of the outside. Although microbial activities were reduced in the environment, remained unchanged on documents. The system was simple to install and inexpensive to operate.
