Anticipation of solar radiation through the building C envelope of campus a Universitas Trisakti

Abstract

The population growth has implication on the demand for construction more buildings, yet there is less attention to take into account the impact towards the environment and/or occupants. The building provides a reflecting surface and measures solar heat radiation, which results in an increase in the heat especially in a tropical climate, leading to the need to cool down the rooms of a buildings. Air conditioners become a solution so as people can conduct their activities more comfortably. Under a possible situation to adapt the environmental factors, the building is designed so as to minimize adverse consequences and to reduce the required energy. The facade of the building is a component that is closely related to the outdoor condition. However, it requires knowledge of the performance of the building's components. The present study is a preliminary research that raises the problem of anticipation of solar radiation through the building envelope. It is a case study carried out at Building C of Campus A of Universitas Trisakti located in Grogol, Jakarta. This building was selected due to its shape and type. An experimental approach was used, preceded by a literature study that discussed climate and solar radiation and then took place in a case study. The purpose and benefits are to provide information for further research and for the architect to design the shape and type of building envelope. The findings reveal that the building envelope and the building direction are strongly influenced by solar radiation. Subsequently, the value of heat transfer in buildings based on SNI 6389-2011 is gained through the OTTV formula. Essentially, suitable shape and type of building envelopes, the right material are important to minimize the need for artificial air conditioning, which means reducing the need for electrical energy.
