American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) 2022, awarded Nadhira Izzatur (Architecture 2018), Sutan Azhari (Architecture 2018), Harrys Argaditya (Architecture 2019), Bagus Rangin (Mechanical Engineering 2018), Edward Joshua (Mechanical Engineering 2018), and Rizki Ramadhan (Mechanical Engineering 2018) who represented Indonesia in the “ASHRAE 2022 International Competition”. The team was under the guidance of Ardiyansyah Yatim, S.T, M.Eng., Ph.D., a lecturer from Department of Mechanical Engineering FTUI, and Dr.-Ing. Ova Candra Dewei, S.T., M.Sc., a lecturer from Department of Architecture FTUI won 1st place Integrated Sustainable Building Design (ISBD) category beat thirteen other teams.
The team participated in the Integrated Sustainable Building Design (ISBD) category which covered the fields of Architecture, Mechanical Engineering, and Electrical Engineering. Competitors are asked to design a building located in Sydney, New South Wales, Australia with ASHRAE standards. In addition, the design of the building must be able to significantly reduce carbon dioxide emissions as manifestation of environmentally friendly building or Zero Net Energy Building (ZEB).
“Zero Net Energy Building is a No Energy building. In this case, buildings are able to reduce energy requirements efficiently and balance the used resources with the produced resources through renewable energy resources. Buildings with the ZEB concept will generate their operational energy requirements from renewable energy sources included wind, water, solar, and others,” said Dr. Ova Chandra who is also the Head of the Multidisciplinary Urban Planning Master Program FTUI.
In order to answer this challenge, the UI team submitted a project design for the UTS Art Center, University of Technology Sydney art building. The team designed a two-story building for the 23,000 square meter arts center by harnessing energy from the sun and wind. There are five energy saving strategies initiated by the UI team, bicycle parking, perfomative building facades, placement of solar panels, making rooftop gardens, and placing vertical greens on building facades.
“The team adopted the round roof of an Australian Aboriginal house to beautify the building on the curved facade. In addition, we also take advantage of Australian grass in the rooftop garden. With a green roof area of 7400 meter square, this building has the potential to absorb 13.8 tons of CO2 per year and release up to 10.6 tons of O2 per year. Especially for the green roof, we use Australian grass plants,” said Nadhira.
“Team members from Mechanical Engineering FTUI contributed ideas in the form calculating the energy needed to cool the building in summer and the energy needed to heat the building in cold weather. Calculations are also made of the used elements design and their impact on the energy efficiency of the building. The goal is the air and hot light from outside are minimal, so the temperature inside the building is maintained. This strategy has been proven to reduce the cost of using air conditioning machines and fans, which amount to 64% of the building’s total energy requirements.” said Dr. Ardiansyah.
“With the different study program background of the students, the important value was grown which is the value of collaboration by implemented each other’s ideas, so they succeeded winning this competition. FTUI encourages the spirit of cooperation and collaboration between students, both in research activities and competitions to prouce superior innovations and have an impact for the society,” said the Dean of FTUI, Prof. Dr. Heri Hermansyah, S.T., M.Eng., IPU.
After winning this competition, the UI team will participate in the ASHRAE 2023 winter meeting which is planned to be held in February 2023 in Atlanta, Georgia, United States. ASHRAE International is a global professional society association commited to serving society by advancing the art and science of ventilation, heating, air conditioning, refrigeration and related fields. The ASHRAE International was founded in 1894 and headquartered in Atlanta, Georgia, USA.
