Sustainable Green Building: Local Law 97 and Its Impact


November 1, 2023

The world of construction and real estate has undergone significant changes due to evolving regulations and standards aiming at promoting sustainable green building and decreasing carbon footprints. Among the multitude of regulations, New York City’s Local Law 97 stands out as a transformative piece of legislation, particularly for those in the construction industry. In this blog post, we will explore the depths of Local Law 97, its definition, and the profound impact it holds for the construction sector.

What is Local Law 97?

Local Law 97 was introduced as part of the Climate Mobilization Act in New York City. It's one of the most ambitious laws in the country targeting reductions in greenhouse gas emissions from existing buildings. The law mandates that large and medium-sized buildings, covering 25,000 square feet or more, must meet certain greenhouse gas emission caps or face significant fines.These caps become progressively stringent, aiming for an ambitious 40% reduction in emissions by 2030 and an even bolder 80% reduction by 2050, aligning with the broader climate and sustainable green building goals of New York City.

The Impact on the Construction Industry

Shift Towards Sustainable Building Techniques

The most direct impact of Local Law 97 on the construction industry is the inevitable shift towards sustainable green building techniques. Buildings that were traditionally constructed without a significant emphasis on sustainability will now need to consider incorporating energy-efficient systems, green roofs, solar installations, and more.

Retrofitting Boom

Existing buildings that do not meet the specified emission caps will need to undergo retrofits. This could mean a boom for construction companies specializing in sustainable green building and retrofitting, from updating insulation to installing energy-efficient HVAC systems.

Innovation in Materials

The law will also spur innovation in construction materials. There will be an increased demand for materials that are sustainable, have better insulation properties, leading to decreased energy consumption, or offer clean energy generation.One such innovation in sustainable green building is Building-Integrated Photovoltaics (BIPV). BIPV systems replace conventional building materials with photovoltaic materials, effectively turning parts of the building's structure into energy generators. These systems offer the potential for cost savings, as they serve a dual purpose as building envelopes and renewable energy sources, pushing the frontier of green construction materials and methods.

Increased Collaboration

Local Law 97 necessitates increased collaboration between architects, builders, sustainability consultants, and other stakeholders. Construction companies will need to work closely with these experts to ensure that new buildings meet the required standards and to retrofit older buildings.

Looking Ahead

Local Law 97, while stringent, underscores the importance of adapting to a changing climate and the role that the construction industry plays in this global challenge. While it poses immediate challenges, the long-term benefits – both environmental and economic – are significant.In the face of this regulation, construction companies have an opportunity to lead the way in sustainable green building, not just in New York City but as a model for the world. Embracing the change can position a company as a forward-thinking, environmentally responsible leader in the field, opening doors to new projects and clients who value sustainability.In conclusion, Local Law 97 is not just a regulation; it's a call to action for the construction industry. The way companies respond and implement sustainable green building techniques will shape the future of construction and, indeed, the future of our cities.
