Air Conditioner Students have complained about it being too hot on stage due to the spotlights. As this issue is caused by the blast of light energy being converted into thermal energy as it contacts the skin and is absorbed by the mass of a body, there are limited ways to tackle this issue. One way would be to reduce the lighting, but at the drawback of having poor lighting quality. Another way would be to make the spotlights scatter light so that the light energy is not so concentrated, which is not only difficult to do, but would waste lots of electricity as well. Our solution was simply to add an energy efficient free standing air conditioner to the corner of the stage and to improve localized cross ventilation so that the area around the stage is a bit colder than the ambient temperature of the room. As well, this air conditioner could double as a dehumidifier to reduce the wear on the cork flooring.
