The law enforces emissions regulations that require most buildings, particularly new york city's largest buildings, to meet advanced limits on greenhouse gas emissions by 2024 and progressively stricter thresholds by 2030.
Owners must reduce greenhouse gas emissions by carrying out energy efficiency improvements, transitioning to clean energy sources, and enhancing building operations to satisfy city requirements.
The compliance journey for owners is nuanced, as allowable emission limits vary according to building category and usage.
Owners must deliver robust energy upgrades and maintain strict reporting, all while working closely with the DOB and participating in NYSERDA-led sustainability efforts.
Henson Architecture: Bridging Heritage and Sustainability for Law 97 Compliance
With a blend of preservation expertise and innovative retrofit strategy, Henson Architecture is poised to support owners committed to achieving compliance.
Since 2003, Henson Architecture has advanced preservation-focused design, always aligned with strict emission and energy standards.
Adapting heritage buildings to fit within carbon emission regulations is a nuanced challenge.

Their specialists offer tailored consulting in NYC, including building envelope upgrades, Passive House retrofits, and full carbon lifecycle reviews—ideal for owners dedicated to both preservation and emissions reduction.
Navigating Compliance: Energy Retrofits and Reporting
Effective energy strategy forms the foundation of Local Law 97 compliance.

Complying requires owners to consistently raise their buildings' energy efficiency in line with city mandates.
Their collaborative process includes energy audits, comprehensive facade revamps, and envelope solutions, all focused on cutting operational energy and emissions.
One of the critical compliance elements is detailed reporting.
NYC’s DOB oversees energy benchmarking and GHG emissions reporting, obliging owners to provide yearly evidence of compliance.
Failure to comply can result not only in fines but in reputational and financial risk.
They streamline owner reporting systems and address every DOB requirement to help avoid risk.
By utilizing ongoing training and working with resources like NYSERDA’s NYC Accelerator, Henson Architecture prepares clients for regulatory change.
