This bill would allow the consideration of open and green spaces as part of a building’s gross floor area when calculating greenhouse gas emissions limits for garden apartments and buildings comprised of condominium and cooperative units and create civil penalty reductions for buildings comprised of condominium and cooperative units This bill would also allow courts and administrative tribunals to consider the median property value of residential buildings containing condominiums and co-ops as a mitigating factor in determining civil penalties for failure to reduce greenhouse gas emissions and would require that the Department of Buildings consider whether to grant an adjustment to a building’s emissions limit requirement based on that building’s prior installation of emissions-reducing technology such as solar panels, submetering, or oil to gas conversions.
