AbstractAn analytical study of the cooling load resulting from power input to lights indicated the need for an experimental determination of some of the parameters involved in the calculations of this load. To meet this need a full scale calorimeter room was built and instrumented by the Division of Building Research of the National Research Council of Canada. This paper presents the results of a series of tests that were carried out using this facility to measure the cooling load for fluorescent lights both with and without air flow through the fixtures, and a set of design coefficients for a range of light fixtures, ventilation rates, and room heat storage capacities. The results of these tests confirm the conclusions reached by the analytical study, namely, that the relation between a step change in power input to lights and the corresponding cooling load component can be described by an exponential type of expression with two independent coefficients. One of them depends on the room heat storage capacity and the other is a function of the way the room ventilation system is arranged and the type of light fixtures that are installed.
