🌿 Revitalizing a Historic Landmark

At the heart of the National University of Singapore's (NUS) Kent Ridge campus stands Yusof Ishak House (YIH), a building with deep roots in student history. Constructed in 1977 and named after Yusof Ishak, Singapore's inaugural president, YIH has long been the bustling home of the NUS Students' Union (NUSSU). For nearly five decades, it served as the epicenter for student leadership, cultural events, and social gatherings, shaping generations of undergraduates into changemakers. However, as sustainability became a pressing priority in higher education, NUS embarked on a transformative three-year renovation starting around 2022, reimagining YIH not just as a nostalgic hub but as a forward-thinking sustainable student collaboration space.

This adaptive reuse project preserved over 90% of the original structure—including iconic staircases and arched roofs—to honor its heritage while slashing embodied carbon emissions. Unlike full demolitions that guzzle resources, this approach cut retrofit costs to about 40% of rebuilding and positioned YIH as Singapore's first net-zero energy heritage retrofit. The official reopening on October 15, 2025, drew 2,500 attendees amid NUS120 celebrations and the WellNUS Festival, marking a new chapter in campus life.

The Renovation Journey: Balancing Past and Future

The rejuvenation of Yusof Ishak House was a masterclass in thoughtful design, led by NUS's Campus Design Innovations Group with architects from AWP and consultants like WSP. The goal? Create an inclusive, student-centric space that aligns with NUSOne—the university's refreshed 2024 education philosophy emphasizing self-discovery, holistic learning, and out-of-classroom experiences. By retaining the 1970s vernacular architecture, the team avoided unnecessary waste and integrated biophilic elements, like views of the campus's secondary rainforest ridge, to boost well-being.

Construction wrapped up in late 2025, earning accolades such as the Holcim Awards 2023 Bronze for Asia Pacific. This recognition highlighted YIH's innovative blend of conservation and decarbonization, setting a benchmark for university infrastructure worldwide. Students and staff now enjoy a space that's not only functional but radiates energy efficiency, proving that heritage buildings can lead the green revolution in higher education.

Achieving Net-Zero Energy: A Milestone for NUS

Net-Zero Energy (NZE) buildings generate as much renewable energy as they consume over a year, a rarity for retrofits in tropical climates like Singapore's. YIH hits this target through rooftop solar photovoltaic (PV) panels offsetting usage, alongside drastic demand reduction. Pre-renovation, the building guzzled 2.2 gigawatt-hours (GWh) annually—equivalent to powering over 400 households. Post-upgrade, projections show a drop of more than 1 GWh, a 72% slash per NUS Campus Sustainability reports.

• Hybrid cooling: Delivers 100% fresh air at 26.5°C using fans and minimal AC.
• Smart sensors: Activate lights and fans only when needed.
• Passive design: Stack-effect ventilation via a central atrium 'lung' with perforated sunscreens.

These features embody NUS's commitment to the UN Sustainable Development Goals, particularly SDG 7 (Affordable and Clean Energy) and SDG 11 (Sustainable Cities). For aspiring sustainability experts, this project offers real-world lessons in tropical net-zero strategies.

New Spaces Designed for Collaboration

YIH now spans four naturally ventilated levels, including a vibrant roof terrace ideal for group brainstorming or sunset chats. Quiet corners cater to solo study, while adaptable multi-purpose rooms host workshops and club meetings. Five dedicated music and dance studios buzz with rehearsals, and PitStop@YIH provides recreational nooks for unwinding. The esports room, a boon for NUS Esports, supports training, tournaments, and socials—addressing their prior space crunch.

Dining has leveled up too: Central Square @ YIH boasts six stalls like Havé Indian Vegetarian and Dapur Pandan, plus Wild Skew bistro and CHAGEE's first Southeast Asia outlet (deaf-friendly design). A 24-hour convenience store ensures late-night fuel. These amenities foster spontaneous collaborations, turning YIH into a true student collaboration hub.

Sustainability Innovations Up Close

Beyond energy, YIH integrates greenery for biophilic benefits, improving mental health amid studies. Daylight floods interiors via redesigned openings, cutting lighting needs. Low-speed fans enhance air movement without excess power. The Holcim jury praised this as a 'thermodynamic lung,' leveraging tropical buoyancy for natural cooling.

This isn't isolated; it ties into NUS's broader push, like UCI's 2024 sustainability roundup. Students contribute via energy monitoring apps, embodying collective responsibility. Such models inspire other Singapore unis, like NTU's green labs. Learn more via the NUS announcement.

Student Perspectives: A Hub Alive with Energy

NUSSU President Stephen Chen captured the sentiment: the 'blank canvas' walls invite new legacies atop solid foundations. Esports head Gio You hailed the fixed venue for community growth. Reopening festivities featured 28 student-led activities—from Chantel Ong's immersive art to therapy dog sessions—drawing raves for fostering connections.

Recent 2026 events, like NUS Arts Festival programs and murals by Pangrok Sulap, keep momentum. A Year 4 student noted, 'It's where ideas collide and lifelong friendships form.' For professors shaping tomorrow's leaders, faculty positions at NUS offer such dynamic environments.

Leadership Insights and Celebratory Launch

Officiating Minister Vivian Balakrishnan, an NUS alum and ex-NUSSU head, reminisced: 'Spend time outside classrooms—these are life's real lessons.' Dr. Kuan Yee Han, former NUSSU president now lecturing, hopes it sparks impact-driven interactions. The event blended performances, crafts, and a WellNUS Resource Fair with peer support.

Details in Straits Times coverage underscore its role in holistic education.

Aligning with NUSOne and Future Prospects

YIH turbocharges NUSOne by enabling self-discovery through clubs and events. Upcoming: mOSAic Fest, electronic music labs, and maker markets. As NUS eyes full NZE campus by 2030, YIH prototypes scalable solutions. Singapore's higher ed sector, with peers like SMU adopting greens, benefits from this leadership.
