7.2.2 Upgrade Buildings To Higher Energy Efficiency
UNS Initiatives to Upgrade Existing Buildings for Higher Energy Efficiency
Universitas Sebelas Maret (UNS) has been steadily working to reduce its carbon footprint through a series of concrete and long-term initiatives, directly supporting the United Nations Sustainable Development Goal (SDG) 7: Affordable and Clean Energy. UNS is committed to developing a sustainable and environmentally friendly campus by implementing green technology and energy efficiency practices. As part of its broader sustainability strategy, UNS has also developed plans to upgrade existing buildings to higher energy efficiency standards. These efforts significantly reduce energy consumption, lower operational costs, and minimize the university’s carbon footprint. Through these far-reaching efforts, UNS demonstrates how higher education can lead the way in achieving sustainability.
Energy Efficient Appliances
UNS has implemented various energy-saving devices as part of its efforts to enhance energy efficiency on campus. Some of the tools used include LED lights, exhaust fans, low-watt air conditioners, automatic faucets, ecoflush toilets, LED monitors, and energy-efficient refrigerators. The application of these energy-saving devices reflects UNS’s commitment to creating a more environmentally friendly campus by reducing energy consumption and supporting sustainability. This initiative aligns with efficient resource management strategies, supports green campus targets, and responds to climate change challenges.

In 2024, UNS provided research and community service funding with a focus on SDG 7 topics to achieve SDG 7: Ensure access to affordable, reliable, sustainable, and modern energy for all. For example, Dr. Wibawa Endra Juwana, through his research “Analisa Teknis Sistem Optimalisasi Efisiensi Konversi Energi Terbarukan” (Technical Analysis of Renewable Energy Conversion Efficiency Optimization Systems), conducted a system analysis relevant to improving energy efficiency in buildings and infrastructure, supporting the effort to upgrade buildings to higher energy efficiency.
