Abstract: Our research aims at analysing the life cycle performance - in terms of primary energy and emissions - of classrooms in certified school buildings located in a humid subtropical climate considering two ventilation strategies (single-sided, SSV, and cross ventilation, CV) and four building envelope scenarios through different life cycle metrics. Operational energy consumption was simulated for all scenarios. The impacts embodied in the shading elements were calculated considering a 50-year life cycle with maintenance. Although SSV classrooms and galvanized steel perforated screens clearly prevail in our sample, our results identified that CV classrooms with shaded windows had the lowest life cycle impacts.
