Ecobuild Green Building Consultant Lead Project Manager, Ainil Khairin, and Project Manager, TB. Syarif Hidayatullah, were invited as speakers for the Energy Consumption Intensity (IKE) Workshop held for students of the Professional Architecture Program at the Faculty of Engineering, Universitas Indonesia, on 11th November 2024.
The rapid growth of population and economy is driving increased global energy demand, particularly in the building sector. As the demand for housing, offices, and public facilities grows, architects and green building consultants play a vital role in designing energy-efficient buildings that reduce environmental impact.
Ainil explained that population and economic growth accelerate energy consumption, especially in the building sector, which results in increased emissions, air pollution, and exploitation of natural resources. Energy-inefficient buildings exacerbate global warming and ecosystem damage, as well as degrade air quality and human health.
Energy Consumption Intensity (IKE) is a term for measuring the energy consumption of a building, by comparing total electrical energy use and building area. Energy Consumption Intensity (IKE) values are used to determine the potential for energy conservation in green buildings.
TB Syarif explained the steps for calculating Energy Consumption Intensity (IKE), starting with collecting documents related to energy consumption, such as utility bills or meter readings for AC, lights, outlets, and other energy sources. Next, the Gross Floor Area (GFA) of the conditioned space is measured. Finally, the Energy Consumption Intensity (IKE) value is calculated using simple calculations or with the help of software to obtain accurate results.
The strategy for reducing Energy Consumption Intensity (IKE) involves both passive and active design approaches. Passive design focuses on reducing the cooling load by optimizing the building’s layout, orientation, insulation, and shading. Active design, on the other hand, enhances energy efficiency by incorporating energy-efficient systems, such as LED lighting, high-efficiency HVAC systems, and smart controls, to reduce energy consumption while maintaining comfort in green buildings.
