In commercial buildings in Lahore, artificial cooling systems are needed to attain the required comfort level due to high heat gain inside. Energy efficient window design is the only solution which can limit this cooling demand. This simulated study is carried out in order to obtain a desirable window size (WWR). The study is carried out by the interpretation of graphical data which is generate...

This paper investigated the impact of Window to Wall Ratios (WWR) an the thermal comfort and energy lighting demand of a building in tropical zone. Simulations were carried out for a reference office proposed by Task 27 of IEA using three Window to Wall Ratios (WWR). Results were analyzed both in terms of operative temperature and energy lighting consumption. Simulations results showed that for...

The natural ventilation and the energy consumption are very important characteristics in buildings. Representation of the patterns for better natural ventilation performance versus lower increase in energy consumption is significant and useful. This study is simulating an office building in the temperate and humid climate of Rasht in Iran, and calculated the annual ventilation and the energy co...

Background: The use of daylight in offices has become an effective strategy to improve the quality of indoor space and energy efficiency. There is enough potential to have daylight autonomy in Kerman as a city with more than 300 sunny days a year. Therefore, this study aimed to investigate the relationship between facades configuration and the amount of daylight in office buildings of Kerman. ...

Good daylighting design in buildings not only provides a comfortable luminous environment, but also delivers energy savings and comfortable and healthy environments for building occupants. The importance of using daylight in educational buildings is because of the synchrony of operating hours of the school and daylight plenitude the sky. Daylight improves environmental quality and saves energy ...

Recently, there have been significant concerns regarding excessive energy use in office buildings with a large window-to-wall ratio (WWR) because of the curtain wall structure. However, prior research has confirmed that impact window area on consumption varies depending building size. A newly proposed window-to-floor (WFR) correlates better building. In this paper, we derived correlation by ana...

Recently, expanded metal mesh has been used on the facades of many buildings in Taiwan. Therefore, this study, we evaluated impact natural lighting and energy consumption office buildings. First, compatibility EnergyPlus DIVA simulation software with was verified using field measurements. The results show a high correlation between measurement, except for some periods direct sunlight. Then, eff...

This study investigates different cases to obtain optimal Window-to-Wall ratio (WWR) in seven climate conditions based on the Köppen–Geiger classification. The WWR was decided minimum amount of total energy use (total cooling, heating, and lighting use) a building model during complete year. impact overhang automatic blinds were assessed optimization for with integrated control. Moreover, three...

As part of sustainable architecture principles and practices, designers need to define building's architectural requirements based on climatic conditions, environmental preservation and reduction in energy consumption. The natural energy sources such as solar radiation affect thermal and lighting performances of buildings depending on its facade characteristics. Traditionally, buildings thermal...
