US buildings face mandates to reduce carbon emissions

Did you know that two-thirds of New York's greenhouse gas emissions come from buildings? This is why the New York City Council enacted Local Law 97 (LL97), which requires building owners and property managers to invest in upgrades that reduce emissions. LL97 is just one of many energy laws governing buildings in the United States.

At Greenwich Energy Solutions, we understand that the path to compliance can be challenging. Our team of energy efficiency consultants is here to guide you every step of the way, from planning to installation and ongoing monitoring. We will ensure your building adheres to energy law requirements and latest ordinances while maximizing the benefits of available incentives. With energy consulting NYC, you can achieve significant emissions reductions and position your building for long-term sustainability.
