Abstract

Unintended air leakage through a building envelope is a major source of energy loss for residential buildings. Air leakage through improperly installed recessed lighting fixtures (RLF) has been identified as one source of unintended air leakage. However, little quantitative study was found on the energy loss through improperly-installed RLF. In this paper, the authors conducted preliminary evaluation of the magnitude of such energy loss by numerical simulations using 3D transient CFD model. One case was studied using boundary conditions of four seasons, which were obtained from historical experimental data from Mississippi. The results of the simulations indicate RLF can be a very significant source of energy loss in both summer and winter conditions. The study suggests that systematic approach is needed to improve the RLF design and construction practice to reduce or remove the RLF's negative impact on energy loss of residential buildings.
