The law establishes 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 introducing energy-saving technologies, switching to clean energy solutions, and enhancing building operations to align with compliance standards.
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’s Sustainable Approach to Law 97 Compliance
By combining historic preservation know-how with leading retrofit techniques, Henson Architecture delivers compliance solutions tailored for distinctive building challenges.
Established in 2003, Henson Architecture combines its heritage preservation ethos with top-tier sustainable design to help buildings hit emission benchmarks while maintaining identity.
Modernizing heritage buildings for emission compliance presents intricate technical and design demands.
These buildings often have period construction details and traditional facades demanding thoughtful intervention to balance performance and preservation.
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
Energy is at the core of Local Law 97’s compliance framework.
Complying requires owners to consistently raise their buildings' energy efficiency in line with city mandates.
In partnership with owners, Henson Architecture delivers energy auditing, restorative facade work, and envelope advancements designed to maximize reductions in energy use and emissions.
Accurate data submission is pivotal for ongoing law 97 compliance success.
Year-over-year data submission to the DOB is necessary to prove alignment with Local Law 97 benchmarks.
Non-compliance may trigger substantial fines as well as negative financial and brand consequences.
Henson Architecture assists owners in establishing reliable reporting processes and managing complex DOB standards.
By utilizing ongoing training and working with resources like NYSERDA’s NYC Accelerator, Henson Architecture prepares clients for regulatory change.
Accelerator and Green Programs: Expanding Compliance Solutions
The reach of Henson Architecture goes further: connecting owners to critical funding streams and sustainability networks.
NYSERDA is instrumental in advancing clean energy by supporting owners with training, analysis, and valuable funding.
Together, NYC Accelerator, Urban Green, and Henson Architecture create a pathway to community-based, practical solutions for building emissions.
These collaborations open doors to both financial support and advanced technical pathways for clean energy and efficiency improvements.
By leading these coordinated efforts, Henson Architecture ensures each client benefits from the most relevant support and funding opportunities.

The firm’s solution blends energy-focused retrofits and creative reuse plans to help buildings surpass the targets set by Local Law 97.
Henson Architecture’s track record reflects projects that marry regulatory compliance (like FISP/Local Law 11) with best-in-class carbon reduction.
Focus on thermal improvements, ventilation modernization, and Passive House investments provides a foundation for exceeding compliance targets.
By focusing on reducing energy intensity and integrating clean energy sources, Henson Architecture empowers owners to transform existing assets into leaders in sustainability.
When Henson Architecture leads from the start, the result is emission reductions that respect both building history and resident comfort.
Empowering Building Owners with Knowledge and Tools
Owner education is a cornerstone of successful Local Law 97 compliance.
Customized owner and manager training empowers stakeholders to grasp energy upgrades, clean energy adoption, and reporting requirements.
Through workshops, seminars, and custom training modules, owners learn how to implement clean energy initiatives, improve energy performance, and comply with reporting obligations efficiently.
Owners who take a proactive, informed approach to law 97 see smoother, lower-risk compliance.

The firm's expertise in sustainability and climate-responsive architecture positions them as trusted advisors for owners striving to maintain operational continuity while navigating new carbon regulations.
The Climate Imperative: Why Building Owners Must Act Now
NYC climate policy leaves no room for delay in reducing greenhouse gas emissions from building stock.
Approximately 70% of all NYC emissions originate from buildings, putting them at the center of policy action.
Local Law 97 defines owner obligations in ensuring buildings play their part in climate solutions.
The firm understands that piecemeal upgrades aren’t enough for most buildings to comply with law 97.
Instead, an integrated approach combining historic preservation, energy efficiency retrofit, and clean energy adoption is essential to placing buildings on a sustainable trajectory.
The firm’s services address this, ensuring that owners meet not only compliance but also long-term resilience and financial performance through reduced energy costs and preserved asset value.
Financial Pathways for Compliance: NYSERDA & Accelerator Resources
Bringing buildings into compliance often involves considerable upfront investment.
Fortunately, various NYSERDA and NYC Accelerator programs provide vital funding pathways that offset upfront costs for owners pursuing Local Law 97 upgrades.
Henson Architecture actively supports clients in securing funding by aligning project scopes with program eligibility, optimizing energy performance metrics, and facilitating training for building operations teams.
In addition to funding, accelerator programs develop owner expertise and connect projects to solar, geothermal, and cutting-edge energy management integrations.
