How NYC Local Law 97 impacts Indoor Environment

NYC Local Law 97 and Its Impact on Indoor Environment

New York City is one of the most densely populated cities in the world, with an estimated population of over 8 million people. As a result, the city has a significant carbon footprint, and the built environment is responsible for a large portion of the city’s greenhouse gas emissions. To address this issue, the New York City Council passed Local Law 97 in 2019, which sets stringent emissions limits for buildings over 25,000 square feet. The law is part of the city’s broader efforts to reduce greenhouse gas emissions by 80% by 2050. We discuss LL97 and Indoor Environment.

While the primary goal of Local Law 97 is to reduce the carbon footprint of buildings, it will also have a significant impact on the indoor environment of buildings. Here’s how:

Improved Air Quality: One of the key components of Local Law 97 is the requirement for buildings to reduce their carbon emissions, which will lead to better air quality. This improvement in air quality will have a positive impact on the health and wellbeing of building occupants, particularly those with respiratory issues.

Improved Thermal Comfort: Local Law 97 also requires buildings to improve their thermal comfort, which is the condition of the indoor environment that satisfies the thermal needs of the occupants. This means that buildings will need to provide adequate heating and cooling, and maintain indoor temperatures within a certain range. Improved thermal comfort can lead to increased productivity and better overall occupant comfort.

Use of Sustainable Materials: To comply with the law, buildings may need to replace their existing systems and equipment with more energy-efficient options. This shift towards sustainable materials and technologies can have a positive impact on the indoor environment, as these materials are often free from harmful chemicals and can contribute to a healthier indoor environment.

Increased Maintenance: To ensure compliance with Local Law 97, buildings will need to undertake regular maintenance and monitoring of their systems and equipment. This increased maintenance can help to identify and address issues that may impact the indoor environment, such as leaks or mold growth.

In conclusion, Local Law 97 will have a significant impact on the indoor environment of buildings in New York City. While the primary goal of the law is to reduce greenhouse gas emissions, the positive impact on indoor air quality, ventilation, thermal comfort, and the use of sustainable materials will benefit building occupants and contribute to a healthier indoor environment. As the law is implemented over the coming years, building owners and managers should be prepared to make the necessary changes to ensure compliance and reap the benefits of a healthier indoor environment.
