The idea of preserving thermal comfort in enclosed courtyards without mechanical heating is examined in this study. The study assesses the effects of different glass types on indoor temperatures throughout the year by contrasting the performance of triple-pane, double low-E, and ordinary double-pane glazing. Temperature fluctuations in an enclosed courtyard under various air change rates (0.5 ACH as a base case, followed by 0.1 ACH and 3 ACH to perform additional testing) were examined using IDA ICE simulation software.

The results show that triple-pane glazing provides slightly better insulation compare to other glass types, keeping temperatures well above ambient temperature. However, in the summer, this glazing contributes to warming, emphasising the necessity for adequate ventilation. In contrast, double low-E glazing provides a more balanced approach, efficiently conserving heat in the winter while allowing for better solar management and daylight penetration, making it more adaptive to year-round conditions.

Although the thermal performance of enclosed courtyards is the main emphasis of this study, energy efficiency and social factors like community well-being are not examined. Instead, it addresses the glazing selection and ventilation rates of creating comfortable and usable enclosed outdoor spaces in cold climates. In relation to the results, enclosed courtyards may act as an effective way to boost urban outdoor spaces all year round with proper glazing and airflow control, much as a greenhouse.
