A study by the National Parks Board (NParks), Building and Construction Authority (BCA), and researchers from the National University of Singapore (NUS), demonstrated the technical feasibility of co-locating solar panels and green roofs. The study, led by Associate Professor Stephen Tay, together with team members Ms. Faizatuzzahrah Rahmaniah and Ms. Joyce Lim Hui Min, reported improved solar panel output, enhanced greenery growth, and reduced indoor temperatures through effective use of limited roof spaces. The study contributes to Singapore’s vision of a “Low-Carbon City” and a “City in Nature”. More information on the work can be found here: https://doi.org/10.1016/j.apenergy.2025.126133.
