INNOVATIVE WINDOWS FOR ENERGY-EFFICIENT CONDOMINIUMS IN HOT AND HUMID CLIMATES

Abstract
Dynamic window technologies aim to incorporate both passive and active designs to introduce natural daylight and ventilation into indoor spaces without increasing heat and glare. The goal is to minimize overall energy usage in condominiums with room sizes ranging from 30 to 35 square meters. This research study in Thailand focuses on several objectives: investigating energy-efficient window designs suitable for condominiums, modeling the performance of dynamic window technologies in response to solar radiation and daylight variations compared to standard windows, and calculating the potential annual energy cost savings with dynamic windows. The study recommends dynamic windows with three main components: cantilevered sun shading for sun and rain protection while maintaining views, stack effect ventilation windows to facilitate heat dissipation and airflow, and horizontal folding shutters that can be operated automatically or manually to control solar heat gain. Overall, the research suggests that implementing dynamic window technologies can lead to substantial energy cost reductions of 430,990 baht per 1000 rooms per year in medium-class condominiums in Thailand compared to traditional windows.
