Local Law 97's timeline mandates that building owners begin emissions reduction efforts in 2024 and continue to lower them by 2030, as part of the city’s climate action plan.
Owners must reduce greenhouse gas emissions by introducing energy-saving technologies, transitioning to clean energy sources, and enhancing building operations to satisfy city requirements.
Owners experience a complex compliance landscape, with emission targets differing based on building type and occupancy patterns.
Owners must deliver robust energy upgrades and maintain strict reporting, all while working closely with the DOB and participating in NYSERDA-led sustainability efforts.

Energy Upgrades and Reporting: The Path to Law 97 Compliance
Energy considerations drive the Local Law 97 regulatory landscape.
Complying requires owners to consistently raise their buildings' energy efficiency in line with city mandates.
Henson Architecture works closely with building owners to perform energy audits, facade restoration, and building envelope upgrades that lower building energy use and cut greenhouse gas emissions.
One of the critical compliance elements is precise submission of data.
NYC’s DOB oversees energy benchmarking and GHG emissions reporting, mandating annual proof of compliance from owners.
Non-compliance may trigger substantial fines as well as negative financial and brand consequences.
The firm helps owners prioritize robust reporting and addresses all DOB expectations for efficient compliance.
Leveraging sustainability training and communication with programs like NYSERDA’s NYC Accelerator, the firm helps clients stay ahead of regulatory mandates.
