Energy efficiency of buildings is of paramount importance due to limited fossil resources, environmental issues, and increasing energy demand. Thus, in recent years building energy analysis using various programs has experienced a rapid growth. However, these programs are expensive and time consuming. In this study, mechanical engineering building of Tabriz University located in northwest of Iran is analyzed to attain a simplified building model that can reduce the computational time and effort. Therefore, 10 models are considered with distinctive design accuracies. EnergyPlus software has been employed to perform energy analysis of the building. The findings show that building materials, internal walls and zoning of the building are determining factors in thermal loads of the building. However, shadings, number of occupants, and electrical appliances have negligible impact. Thus, it can be concluded that the model in which a detailed envelope design is considered and interior walls, shades, electrical appliances, and duration of occupancy are omitted, has the optimum performance in terms of time saving and accuracy of load calculation. Moreover, to gain more reliable results, it is recommended to consider zones in model No.5. The difference between natural gas and electricity consumption of the first and last models is 20,302 m3 (2200$) and 1157 kWh (90$) that indicates the significance of proper HAVC sizing. It is worth mentioning that all monetary units are presented in 2018 U.S. dollar. © 2018 American Institute of Chemical Engineers Environ Prog, 38: 741–749, 2019

This paper presents the study of the performance of building-integrated photovoltaic (BIPV) applied on vertical building envelope as overhang shading devices on energy saving. In Indonesia, where solar energy is abundant, the utilization of PV system as renewable energy is very potential, especilly in remote area. However, in the urban core of Indonesia, the utilization of PV system is not yet economically viable. In this study, six BIPV models with different design of PV panel shading devices were simulated using weather file of Jakarta, an urban core of Indonesia. The results show that installing fewer PV panel shading devices on building façade with greater distance is more effective than installing more PV panel shading device with less distance. The LCOE (levelized cost of electricity) of all models that is lower than the national grid electricity cost indicates that BIPV could be economically profitable if it is designed properly.

This study presents an investigation of the effect of building envelope, especially glass facade buildings on cooling energy usage and thermal comfort. An office building was modeled with various window-to-wall ratio (WWR) using panasap glass with SC=0.58 in order to analyze the effect of the WWR addition on cooling energy usage and comfort temperature. The result suggested that the average increase of the cooling energy usage is about 5.67% per 10% WWR addition, and of the operative temperature ranges from 0.35 0 C to 0.56 0 C per 10% WWR addition. Moreover, the building with above 20% WWR doesn't provide comfort temperature.
