Sustainable Climate Control for Historic Buildings in Hot and Humid Regions

This paper describes ventilator-heater based climate control systems installed in two historic buildings, each located in hot and humid regions, for full-scale experiments.
The systems were controlled based on RH sensors located inside and outside of the buildings. Their environments were monitored—before and after the installation and operation of the climate systems—to evaluate the design effectiveness. Less than 70% RH was maintained. Dust depositions have increased as a result of air movement only, given that the supply air has been filtered. The microbial activity was reduced significantly in one case. The installation of the systems and some modification in the buildings were very simple. The systems are completely automated and robust, and in one year of operation, there was no need for maintenance or repair. The operation and the running costs of the ventilators and heaters were documented during the study. |
