    BY THE end of 2024, energy-intensive buildings will be subject to audits under a new Mandatory Energy Improvement (MEI) regime. 

    The Building and Construction Authority (BCA) estimates that, at present, 55 per cent of buildings are green by gross floor area (GFA). 

    However, some older buildings with poor energy performance do not meet the new minimum energy-performance standards, and their owners may face large bills in attempting to do so.
