Abstract:

With the increasing awareness of sustainable development in the building construction the assessment of energy demands for heating/cooling under the influence of extended glazing fa?ade, type of glazing, building orientation and energy control management strategies have become more important. In this study, focus is given on the energy performance assessment of a building zone with an entirely glazed fa?ade, with four types of glazing at various orientations, by defining: (a) a desirable indoor zone temperature margin (ZTM) and (b) a desirable indoor minimum overnight temperature (MOT). Particular emphasis is given on the overheating during the summer season by introducing and evaluating the overheating temperature-index (OTI) for the examined glazing systems. The modeling and mathematical formulation is based on the thermal-network modeling approach with distribution of solar radiation on both the external and internal zone surfaces in 15 min time increments. Simulation results are given for a building zone located at the Mediterranean region.
