Abstract:

Purpose University students spend a considerable amount of time in dorm rooms, where their environmental condition affects residents' health, well-being, sleep quality and the associated performance. Accordingly, this study aims to run an initial assessment of the environmental quality of two dormitory buildings in Tehran, using field studies and computational simulation, and then provide feasible optimized improvement strategies. The possible correlation between architectural elements and the environmental quality and the impact of proposed solutions on the annual energy use of these spaces are also discussed. Design/methodology/approach Field studies and computational simulation. Findings Results indicate that applied strategies, including shadings, reflectors, thermal and acoustic insulations, inlet vents and ceiling fans, can boost different aspects of the thermal condition, ventilation, acoustics and visual comfort by 21.77, 55.96, 20.69 and 50.37%, respectively. Accordingly, an acceptable comfort level can simply be achieved at a low cost by installing or replacing a few construction elements in dorm rooms. Nevertheless, a systematic architectural design can offer healthy spaces. For instance, south-facing rooms with large windows provide a higher level of thermal comfort and daylight quality. Research limitations/implications This study shows that an acceptable level of IEQ can be achieved in dorm rooms by applying simple retrofit strategies. Moreover, energy consumption of dormitories can be significantly reduced using these solutions. However, the efficiency of the strategies in comparison to their economic aspects should be discussed, and results need to be further validated in real conditions. It is also recommended that a more extensive range of dormitory room typologies be studied in future studies. The results of this study are limited to the study context and so they can only be applied in case studies with similar use and climatic condition. Original
