Operational Energy Analysis of an Educational Building Design; A Case Study of Center of Excellent (CoE) Building at Universitas Pendidikan Indonesia (UPI)

Abstract

Operational energy contributes significantly to the most energy consumption of a building's life cycle. Analysis of operational energy is usually conducted when a building is being operated. However, we can compare and predict the operational energy of a building's designs to obtain the best design alternative low energy building. The objective of this study is to simulate the operational energy of the design of the Centre of Excellent (CoE) building at Universitas Pendidikan Indonesia (UPI). Rhinoceros and Grasshopper with Ladybug and Honeybee are selected as the software simulation due to the comprehensive features of energy simulation. This modern building will be constructed for five floors with an area of about 5000 m2 per level facing south and north sides. Analysis of operational energy calculated three main factors of cooling, lighting, and other equipment. The result shows that the annual operational energy contributes to about 586 kWh/m2 per year. This value is far from the basic standard for educational building, with about 240 kWh/m2 per year from ASEAN. The cooling system of the building is recorded as the highest amount of energy use. Further, evaluating the building's operational devices and the strategy to reduce the energy loads will be proposed to accommodate a modern school building's main issue that harms operating energy.
