Abstract
The influence of courtyard on the thermal performance of Development Department office building in University Malaysia Perlis (UniMAP, Pauh Putra campus) is investigated through simulation study for the effect of ventilation on indoor air temperature and relative humidity of the building. The study is carried out using EnergyPlus simulator interface within OpenStudio and SketchUp plug in software to measure both of air temperature and relative humidity hourly on 21 April 2017 as a design day. The results show that the ventilation through the windows facing the courtyard has sufficient effect on reducing the air temperature compared to the ventilation through external windows since natural ventilation is highly effective on driving the indoor warm air out to courtyard. In addition, the relative humidity is reduced due to ventilation since the courtyard has high ability to remove or dilute indoor airborne pollutants coming from indoor sources. This indicates that the presence of courtyard is highly influential on thermal performance of the building.
Highlights
The increment in human activities and industrial revolution leads to sharp changes in the ecosystem and in climate due to the incredibly increase in earth temperature, which in turn causes global warming phenomena
The continued increases in global warming and energy consumption required to apply sustainable concepts in order to reduce their effect in daily life
The results show that for all cases opening the windows after midnight until early morning, from 12:00 am to 8:00 am has unnoticeable effect on the interior air temperature since the outdoor air temperature is very close to the indoor air temperature
Summary
The increment in human activities and industrial revolution leads to sharp changes in the ecosystem and in climate due to the incredibly increase in earth temperature, which in turn causes global warming phenomena. The continued increases in global warming and energy consumption required to apply sustainable concepts in order to reduce their effect in daily life. Applying sustainable concepts in buildings considered one of main approaches to maintain energy consumption [2]. Many solutions have been proposed to improve the thermal comfort of buildings in hot humid areas. Among of them, introducing courtyard to buildings enhances the thermal performance for the building’s interior due to its impact on the passive cooling [3]
