ABSTRACTThe demand on energy consumption is ever increasing, making it necessary to develop appropriate materials that can help maintain consumption levels. Windows in a building are very susceptible to heat loss and heat gain, which cause fluctuations in indoor temperature, and often results in the demand placed on air conditioning systems to regulate the indoor space temperature. In buildings with the appropriate type of glazing, considerable decrease in energy consumption can be observed as glazings possess thermal properties that help maintain the temperatures within the spaces. High temperatures within spaces are often from heat gain through window glazing therefore the type and design of windows are important considerations to reduce the heating and cooling needs. This study aims to examine a specific variable in glazing, temperature differential, in a hot and humid climate as an examination of one type of performance measurement. Ultimately, this can assist to provide a support for glazing selection and the design of windows in buildings. A case study was conducted as part of a building renovation project at the University of West Florida. Research components were purposely built into the envelope of the structure which includes a 12-pane fixed window, constructed on the west side of the structure, with multiple types of glazing. Thermal sensors were attached to both the inside and outside of each pane to measure the surface conditions and readings were taken at 15-minute intervals for a period of 1 year. The main objective of the study was to assess the performance of glazing alternatives, compared to the anticipated performance based on the manufacturers’ specifications, which; can assist in the selection of the most appropriate glazing.
