Abstract
A global phenomenon currently prevails in installing an extensive array of glazing systems in multi-unit residential edifices. Some urban occupants are opting to sheath their balconies predominantly with glass to mitigate issues associated with open balconies (OBs), such as glare, pollution, wind, insects, birds, safety and noise and to augment their living space. The effectiveness of glazed balconies (GBs) in cold and warm climates has been extensively debated, and their advantages and disadvantages have been highlighted. Nonetheless, these studies have not examined the issues related to GBs in moderate climates. Hence, this research adopted a comprehensive approach towards user satisfaction, diverse design parameters, climatic conditions and simulation outcomes. This study explored occupants’ satisfaction levels and perceptions towards OBs and GBs via surveys and determined the issues that warranted attention. Furthermore, OBs and GBs were compared and juxtaposed against thermal comfort, temperature and humidity variation, daylight, and wind via field measurement and simulation. Daylight simulations were performed using Rhino and wind analyses using IESVE. The findings indicated that GBs perform better in moderate climates. Moreover, individuals with OBs were inclined towards installing balcony enclosures in the future. GBs considerably increased the temperature and reduced the humidity in comparison with their open counterparts.
