Henson Architecture’s Local Law 97 Solutions: Reliable Expertise at Your Service
Amidst climate change and increasing emission rates, Local Law 97 has proven to be a cornerstone for regulating New York City’s largest buildings.
Originating from the Climate Mobilization Act, Law 97 institutes forward-thinking carbon caps on buildings, with the goal of lowering GHGs considerably by 2030 and after.
For building owners, compliance with LAW 97 is not merely a regulatory hurdle but an opportunity to embrace sustainability in the city’s built environment.
Building owners turn to Henson Architecture for experienced guidance across these challenging requirements, underpinned by deep knowledge in historic preservation, adaptive reuse, and sustainability-focused upgrades.
How Local Law 97 Shapes the Future of NYC Buildings
NYC stands at the cutting edge of urban green, as most buildings exceeding 25,000 sq. ft. are subject to Local Law 97’s establishes carbon emission limits supporting aggressive city climate targets.
It focuses primarily on reducing emissions from existing buildings, recognizing that New York City's largest buildings contribute substantially to the city’s overall 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.
Owners face enforcement and penalties monitored by the DOB, with significant focus on reporting validated through Local Law 87 audit processes.
By 2024, many NYC buildings face their first compliance deadline, placing urgency on building owners to act now.
Meeting the Demands of Law 97: Building Owners’ Key Challenges
Navigating the requirements of Law 97 can be difficult and confusing for many owners.
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.
As Local Law 97 places carbon caps, building owners have put forth ambitious emissions targets not to just meet code but to pivot to sustainability-oriented building operations.
This transition requires technical expertise in energy analytics, building envelope performance, HVAC system upgrades, and the integration of clean energy solutions such as solar and other renewable resources.

Custom Approaches to Local Law 97: Our Service Spectrum
Navigating the regulatory landscape demands an integrated approach: from energy audits and reporting to building envelope consulting NYC, facade restoration, and Passive House retrofit strategies.
Henson Architecture supports building owners through every stage:
- Thorough Energy Use Analysis & Reporting: Timely and precise reporting is essential. Local Law 97 demands detailed energy and emissions reporting, which we streamline through rigorous data collection and analysis. We help owners consistently deliver accurate, compliant reports to the DOB, preventing costly penalties.
- Building Envelope and Facade Consulting: Aging facades and suboptimal envelopes often lead to significant energy loss. By assessing and improving envelope conditions, we merge classic craftsmanship and contemporary sustainability.
- Passive House and Energy Retrofit Design: We focus on applying high-performance retrofit solutions that greatly reduce operational energy demand. New York City owners benefit from these upgrades through lower energy costs and lifespan extension for assets, meeting ambitious emissions targets set by the law.
- 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 Henson Architecture actively collaborates with sustainable energy programs such as NYSERDA and the NYC Accelerator to provide building owners with comprehensive support. Funding, training, and expert guidance from NYSERDA are available to support meaningful improvements in building energy performance.

Such programs highlight NYC’s dedication to advancing sustainability and simultaneously supporting owners with education and resources. Addressing Climate Goals through Adaptive Reuse and 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. Our focus on adaptive reuse and sustainability-driven retrofits cuts both embodied and operational carbon over a building’s life cycle. Law 97’s scope means that most buildings offer room for substantial enhancement, especially regarding mechanical equipment or envelopes. Our expertise marries traditional preservation techniques with progressive solutions that maintain heritage significance and ensure code compliance. We assert that the greatest climate impact comes from upgrading existing buildings—critical venues for carbon caps and compliance with new GHG targets. Compliance Management, Transparent Reporting, and Future Preparedness The DOB’s enforcement role entails close scrutiny of building compliance and reporting under Law 97. Owners are required to provide yearly emissions data, documenting both energy use and carbon cap adherence. Non-compliance brings harsh financial penalties and risks lowering property valuation. We help owners fulfill reporting mandates with clarity and detailed documentation designed for DOB acceptance. Our involvement as trusted advisors ensures building owners stay ahead of compliance schedules, benefiting from strategic interventions rather than reactive measures. Moreover, we emphasize future-proofing buildings by incorporating forward-looking sustainability strategies, helping owners adapt to evolving requirements under future climate legislation. Beyond day-one compliance, we focus on nurturing long-term building performance and resilience. Empowering Owners: Training & Education for Law 97 We empower owners and management teams with individualized training and support designed for both Law 97 and greater sustainability goals. Through partnerships with NYSERDA and NYC Accelerator, we help clients understand emerging carbon limits and equip them with the knowledge to manage ongoing compliance.
