Expert Local Law 97 Solutions from Henson Architecture: The Trusted Choice
As NYC faces the challenge of climate change as well as growing greenhouse gas concerns, Local Law 97 stands as a groundbreaking policy designed to regulate GHG emissions among 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 building owners, compliance with LAW 97 is not merely a regulatory hurdle but an opportunity to embrace sustainability in the city’s built environment.
At Henson Architecture, we deliver guidance to owners to navigate complex energy requirements, leveraging our expertise in historic preservation, adaptive reuse, and advanced sustainable retrofits.
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.
Owners face enforcement and penalties monitored by the DOB, with significant focus on reporting validated through Local Law 87 audit processes.
With 2024 compliance deadlines looming, building owners now face urgent requirements within Local Law 97’s framework.
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 expects owners to report with precision and strictly meet emissions limitations set forth under the law.
Assessing energy use, determining a GHG baseline, and customizing a compliance plan aligned with new carbon emission limits are essential steps for owners.
Because Local Law 97 is placing carbon caps, owners have put forth ambitious emissions targets; this is about meeting both code and transforming building operations towards sustainability.
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.
