     the use of solar passive strategies such as new solar control coatings on windows for buildings with large glazed areas, have recently become important and helpful tools, mainly because these developments help to reduce heat gains and/or losses through transparent materials, diminishing energy loads, and improving the environment inside buildings. this paper shows an assessment of the thermal performance for an office on top of a building with four different configurations of window glass, and their influence on the indoor conditions. the window glass configurations are: clear glass, glass-film (snscuxs solar control coating), double-glass-film, and double clear glass. the simulations were carried out using weather data from mexico city and ottawa, which are a good representation of two extreme weather conditions, in order to assess the thermal behaviour inside offices, such as energy loads, costs for air conditioning, and the influence of interior heat transfer coefficient correlations. the results indicate that the glass-film proves to be the less appropriate configuration due to the high temperatures reached on the film surface, which has an impact on the air temperatures inside the office and contributes to increase the energy consumption. in general, the double glass-film configuration results to be adequate for both climates, nevertheless it shows a better performance for ottawa than mexico city, where a simple double clear glass would work the same way.
