BCA Green Mark Scheme
BCA Green Mark is a green building rating system to evaluate a building for its environmental impact and performance.
It provides a comprehensive framework for assessing the overall environmental performance of new and existing buildings to promote sustainable design, construction and operations practices in buildings. The BCA Green Mark Scheme also encourages the adoption of renewable energy sources, including solar power.
