Relates to energy efficiency improvements and certain alterations to multiple dwellings

This bill amends the New York State Multiple Dwelling Law to update technical definitions and window area calculation rules. It replaces the term 'U-factor' with 'coefficient of heat transmittance' to align with current building codes and clarifies that HVAC equipment now refers to 'heating, ventilation and air conditioning' equipment. These changes ensure the law accurately reflects modern energy efficiency standards without altering the specific percentage allowances for reducing window sizes.
