The law sets forth emissions regulations that require most buildings, particularly new york city's largest buildings, to meet advanced limits on greenhouse gas emissions by 2024 and even stricter targets by 2030.
Emission reduction is achieved when owners integrate efficiency upgrades, utilize clean energy, and fine-tune building system operations to match city-mandated limits.
For building owners, the path to compliance is complex, with variable emissions limits depending on building type and occupancy.
It demands diligent energy performance upgrades combined with detailed reporting and coordination with agencies like the New York City Department of Buildings (DOB) and key sustainability programs such as NYSERDA (New York State Energy Research and Development Authority).
Henson Architecture: Bridging Heritage and Sustainability for Law 97 Compliance

Founded in 2003, Henson Architecture harnesses decades of craftsmanship, technical rigor, and cutting-edge sustainable design principles to deliver projects that preserve historic character while achieving aggressive energy and emissions goals.
Modernizing heritage buildings for emission compliance presents intricate technical and design demands.
These buildings often have outdated systems and historically significant features needing skillful upgrades to maintain original design.
By leveraging their NYC building envelope consulting, Passive House approaches, and carbon lifecycle reviews, Henson Architecture provides all-encompassing support to owners focused on compliance and historic protection.
Navigating Compliance: Energy Retrofits and Reporting
Effective energy strategy forms the foundation of Local Law 97 compliance.
Owners must act by investing in energy optimizations that help their buildings align with emissions rules.
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 precise submission of data.
The DOB demands yearly reporting on energy use and emissions, so owners must provide transparent compliance documentation.
Falling short of reporting rules brings the threat of penalties and can impact both reputation and bottom line.
The firm helps owners prioritize robust reporting and addresses all DOB expectations for efficient compliance.
By utilizing ongoing training and working with resources like NYSERDA’s NYC Accelerator, Henson Architecture prepares clients for regulatory change.
Leveraging NYSERDA, NYC Accelerator, and Urban Green Initiatives
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, actively working with Henson Architecture, provide technical seminars, resource guides, and engagement opportunities to drive new ideas in emissions reduction.
Through these partnerships, owners gain access to accelerated pathways for energy efficiency improvements and clean energy integration.
Henson Architecture champions such collaborations, helping clients optimize available funding and develop customized retrofit strategies aligning with NYC’s evolving climate policies.
Design and Construction Strategies to Meet New Emissions Limits
