Expert Local Law 97 Solutions from Henson Architecture: The Trusted Choice
With climate change and GHG emissions taking center stage in New York City, Local Law 97 serves as a defining guideline that establishes emissions controls over New York City’s largest buildings.
Passed as part of the Climate Mobilization Act, Law 97 sets ambitious carbon emission limits on buildings, placing carbon caps designed to reduce greenhouse gas emissions significantly by 2030 and beyond.
For owners, compliance with LAW 97 goes beyond a bureaucratic hurdle: it also presents an opportunity to further sustainability within the city’s fabric.
At Henson Architecture, we specialize in guiding building owners through these complex energy demands, offering expertise grounded in historic preservation, adaptive reuse, and sustainable retrofit.
Local Law 97: Implications and Opportunities for NYC Buildings
Affecting most buildings larger than 25,000 square feet, Local Law 97 establishes carbon emission limits and positions NYC as a leader in urban green initiatives, aligned with citywide climate ambitions.

Local Law 97 zeroes in on reducing emissions from existing buildings since New York City’s largest buildings are major contributors to the total carbon footprint.
Owners seeking compliance must enhance energy usage and transition toward clean energy practices, achieving substantial GHG reductions in the process.
Put simply, Local Law 97 establishes emissions regulations that call for direct and indirect GHG limits, strongly motivating performance upgrades focused on efficiency.
Strict reporting and potential penalties are enforced via the NYC DOB, often working in tandem with Local Law 87 energy audits.
With 2024 compliance deadlines looming, local law 97 building owners now face urgent requirements within Local Law 97’s framework.
Meeting the Demands of Law 97: Building Owners’ Key Challenges
For many building owners, understanding and meeting the requirements of Local Law 97 can be a daunting process.
The DOB enforces these requirements with a focus on accuracy in reporting and strict adherence to emissions limits.
Owners are required to evaluate their current energy consumption and greenhouse gas emissions, and develop a compliance roadmap in step with shifting emission limits.
With the placement of carbon caps by Local Law 97, owners have put forth ambitious emissions targets and are shifting their operations towards a sustainability focus, not just compliance.
To achieve these ambitious targets, expertise is needed in energy analysis, improving envelope performance, HVAC retrofits, and expanding clean energy use—especially solar and related renewables.

Custom Approaches to Local Law 97: Our Service Spectrum
Regulatory success with Local Law 97 relies on coordinated steps: energy audits, trusted reporting, envelope and facade consulting, and advanced retrofit tactics.
Henson Architecture supports building owners through every stage:
- Complete Energy Data Analysis and Reporting: Reliable, punctual reporting is vital. Local Law 97 demands detailed energy and emissions reporting, which we streamline through rigorous data collection and analysis. Owners can rely on our experience for flawless DOB submissions, ensuring ongoing compliance and penalty avoidance.
- Building Envelope and Facade Consulting: Many buildings suffer from energy loss through deteriorated facades and inefficient envelopes. By assessing and improving envelope conditions, we merge classic craftsmanship and contemporary sustainability.
- Advanced Energy Retrofit & Passive House Consulting: Our emphasis is on top-tier retrofits that sharply lower ongoing energy consumption. Such retrofits help owners cut costs, extend their buildings’ usable life, and reach the emissions goals outlined by Local Law 97.
- Deploying Clean Energy for Compliance: Integrating clean energy systems ensures long-lasting compliance and ongoing reductions in operational emissions. We help owners select and integrate the right combination of solar, storage, and renewables needed under the compliance framework. Tapping NYSERDA and Accelerator Programs for Effective Compliance We partner regularly with NYSERDA and NYC Accelerator, offering owners extensive support packages scaled for their needs. Funding, training, and expert guidance from NYSERDA are available to support meaningful improvements in building energy performance. Through participation in these partnerships, building owners unlock resources that streamline upgrades while ensuring compliance. The NYC Accelerator also provides essential support and customized training programs for owners tackling Law 97 compliance. We help owners tap into these resources, minimizing retrofit expenses and fast-tracking project completion. These initiatives demonstrate the city's commitment to sustainability while supporting building owners through funding and education. Achieving Climate Targets: Adaptive Reuse & Sustainable Retrofits Our work is rooted in both sustainability and long-term climate resilience. The law works in tandem with NYC’s citywide climate blueprint aiming for significant GHG reduction in years to come. Adaptive reuse paired with sustainable retrofitting results in notably lower construction carbon and ongoing operational emissions. Most buildings subject to Law 97 present significant opportunities for improvement, from outdated mechanical systems to inefficient building envelopes. Our expertise marries traditional preservation techniques with progressive solutions that maintain heritage significance and ensure code compliance. This approach champions the principle that existing buildings are the key to the city’s climate goals, representing the most impactful arena for placing carbon caps to meet new GHG emissions thresholds. Staying Ahead: Compliance, Reporting & Securing Your Building’s Future The DOB’s enforcement role entails close scrutiny of building compliance and reporting under Law 97. Building owners must submit annual emissions reports, with evaluations of energy consumption and adherence to emissions limits. Failure to comply results in steep fines and diminished property value. Henson Architecture supports these reporting requirements, delivering transparent, precise documentation that meets DOB standards. With our guidance, owners can anticipate compliance needs and benefit from forward-thinking adjustments instead of last-minute responses. Future-proofing is central to our approach, enabling owners to adapt swiftly and efficiently to future regulatory change.
