Energy Consumption Analysis For Courtyard Design Office Buildings In Composite Climate

Abstract

Passive design is widely acknowledged as a cost-effective and efficient approach to sustainable building practices. However, there is still a lack of comprehensive scientific testing methods and conclusive results regarding the validation of passive design strategies. By comparing the energy usage of office buildings with and without courtyards and focusing on analysing their influence on building energy performance, this study tries to close this gap.

To validate and optimize the influence of passive spaces on sustainable buildings, a rectangular courtyard approach is employed in this research. The research considers elements like occupant happiness and the quality of the built environment, and it recognises inner courtyards as efficient climate modifiers that allow for the assessment of comfort perception in the surrounding environment. In order to maximize daylighting and energy savings within building interiors, the proposed systems replace the eaves of roofs over the courtyard with glazed devices.

Two scenarios are used to apply the research methodology: a case study that takes the courtyard impact into account in terms of air temperature, humidity, bulb temperature, and heating and cooling settings, and a reference scenario that does not. According to the findings, a courtyard lowers the need for cooling in nearby spaces. Additionally, the floor, roof, and wall levels of the structure have an impact on the energy demand, with lower floors in the courtyard building having a higher energy demand. 126 (without courtyard) and 130 (with courtyard) are discovered to be the effective coefficient ratios for energy consumption.

These findings offer valuable insights for architects, providing a deeper understanding of the energy consumption associated with different courtyard configurations. This knowledge can facilitate the creation of more energy-efficient designs. It is important to note that in office buildings without a courtyard design, the use of fully passive heating and cooling systems and good daylighting functionality can result in energy savings of up to 3%.
