Sustainability certification schemes evaluate buildings' sustainability by assessing aspects such as energy consumption, performance, facility management processes, social acceptance, and occupant satisfaction. These certifications offer standardized evaluation methods for sustainability, helping reduce consumption, lower costs, and minimize environmental impact. They enhance transparency in the real estate market by informing buyers and tenants about a building's sustainability achievements. Additionally, they guide owners in identifying areas for improvement. Whether mandatory or voluntary, these certifications play a crucial role in promoting sustainable practices and enhancing buildings' marketability.
