Henson Architecture’s Local Law 97 Solutions: Reliable Expertise at Your Service
With climate change and GHG emissions taking center stage in New York City, Local Law 97 serves as a key legislative framework that establishes emissions controls over 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 owners, compliance with LAW 97 is more than a legal requirement: it also presents an invitation to advance sustainability within the city’s fabric.
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.
Understanding Local Law 97 and Its Impact on NYC Buildings
Local Law 97 establishes carbon emission limits for most buildings over 25,000 square feet in NYC, placing the city at the forefront of urban green policies aiming to meet new GHG emissions limits consistent with the city's climate goals.
Local Law 97 primarily targets emission reductions 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.
Owners must meet emissions regulations under Local Law 97, putting a direct emphasis on efficient performance upgrades and GHG controls.
The law enforces strict reporting and penalties primarily through coordination with the NYC Department of Buildings (DOB) and Local Law 87 energy audits.
By 2024, many NYC buildings face their first compliance deadline, placing urgency on building owners to act now.
Law 97: Challenges and Solutions for Building Owners
For numerous building owners, Local Law 97’s requirements present a complex and often overwhelming challenge.
The DOB enforces these requirements with a focus on accuracy in reporting and Local Law 97 consulting services 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.
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.
