Controlling the Environment Within a New Storage and Display Facility for the Governor General’s Carriage
This paper is a technical report which describes the retrofitting of low-cost environmental controls into a small building which was constructed to house and display the Governor General’s carriage. The carriage was built in the 1890s, and is still used on ceremonial occasions. A small building with plate glass windows on all sides and a flat roof had been recently constructed to display the carriage under secure conditions. As a result of the design, however, the interior of the building was subject to wide humidity fluctuations, and at certain times of the year sunlight fell directly on the black panels of the carriage. The paper describes the use of a fan, a common household thermostat, a humidistat, an electric heater and a portable dehumidifier to control the fluctuations in relative humidity. Solar effects are controlled using vertical blinds on the south, east and west windows, which must be closed at certain times of the year to prevent sunlight falling on the carriage. An improvement in the relative humidity control within the building was demonstrated.
