The law sets forth emissions regulations that require most buildings, particularly new york city's largest buildings, to comply with new ghg emissions limits by 2024 and increasingly tight emission limits by 2030.
Owners must reduce greenhouse gas emissions by introducing energy-saving technologies, adopting clean energy systems, and optimizing building systems 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.

Managing Energy Retrofits & Reporting under Law 97
Energy is at the center of Local Law 97’s compliance framework.
The law mandates that building owners implement meaningful energy efficiency measures to meet emissions targets.
In partnership with owners, Henson Architecture delivers energy auditing, restorative facade work, and envelope advancements designed to maximize reductions in energy use and emissions.
One of the critical compliance elements is detailed reporting.
Year-over-year data submission to the DOB is necessary to prove alignment with Local Law 97 benchmarks.
Falling short of reporting rules brings the threat of penalties and can impact both reputation and bottom line.
Henson Architecture assists owners in establishing reliable reporting processes and completing DOB procedures smoothly.
The firm coordinates sustainability workshops and connects with NYC Accelerator to ensure clients understand future compliance needs.
How Henson Architecture Supports Clean Energy Partnerships
Outside of compliance, the firm positions building owners to take advantage of incentives, technical resources, and collaborative platforms.
With NYSERDA’s assistance, owners gain access to critical expertise and funding to make compliance with Law 97 viable.
The NYC Accelerator and Urban Green Council, in close collaboration with Henson Architecture, deliver workshops, advanced resources, and community forums for innovative emissions reduction.
These collaborations open doors to both financial support and advanced technical pathways for clean energy and efficiency improvements.
The firm serves as both advocate and guide for owners seeking greater value in emissions reduction investments.
Design and Construction Strategies to Meet New Emissions Limits
Achieving compliance with Local Law 97 is not solely about mechanical updates; it depends upon integrated design approaches that minimize both energy use and emissions.
Henson Architecture’s methodology combines sustainable retrofit design with adaptive reuse techniques, ensuring that buildings achieve superior levels of energy and carbon performance.
The firm’s portfolio includes numerous projects where landmark agency filings and facade inspection programs (FISP/Local Law 11) intersect with carbon reduction goals.
Upgrades like envelope insulation, advanced ventilation, and Passive House concepts ensure that buildings maintain comfort while staying under new emission limits.
The firm’s continuous focus on low energy use and clean energy integration turns properties into urban sustainability models.
Expert involvement from project inception ensures that retrofit measures are planned to yield both carbon savings and ongoing building quality, with no loss to architectural or occupant value.
Supporting Owners With Training and Resources
Educating owners is central to achieving and maintaining compliance with Local Law 97.

Henson Architecture provides practical training and knowledge-sharing sessions to owners and management on compliance essentials.
Through workshops, seminars, and custom training modules, owners learn how to transition to clean energy, boost building energy performance, and meet reporting standards with ease.
In this evolving regulatory landscape, staying ahead and making smart choices is key to avoiding disruptions and meeting standards smoothly.
The firm's expertise in sustainability and climate-responsive architecture ensures that owners have a reliable partner for balancing building operations with new emissions rules.
The Climate Imperative: Why Building Owners Must Act Now
The city's forward-looking climate goals demand immediate, large-scale greenhouse gas reductions by building owners.
Approximately 70% of all NYC emissions local law 97 originate from buildings, putting them at the center of policy action.
Through Local Law 97, every building owner has a new, clear climate mandate in NYC.
The firm understands that piecemeal upgrades aren’t enough for most buildings to comply with law 97.
Integrated services spanning preservation, energy retrofits, and clean energy unlock real sustainability progress for NYC buildings.
Their approach supports owners in reaching compliance and securing lasting value through energy savings and building preservation.
Support & Funding: Making Law 97 Improvements Possible
Compliance investments can be substantial.
Thankfully, NYSERDA and the NYC Accelerator offer important support and funding to help owners manage project costs.
The firm helps owners maximize funding eligibility by tailoring project plans for NYSERDA/Accelerator support and offering targeted operations training.
These programs facilitate owner learning and open the door to implementing renewables and smart energy management in compliance projects.
