Local Law 84 vs Local Law 97: What Building Owners Need to Know
Local Law 84 and Local Law 97 are two important NYC building performance laws, but they do not do the same thing. Local Law 84 focuses on annual benchmarking of energy and water use, while Local Law 97 focuses on greenhouse gas emissions limits for many large buildings. EnergiDash helps teams understand the data connection between these two requirements.
What Local Law 84 Covers
Local Law 84 requires covered buildings to benchmark and report annual energy and water performance. The purpose is to create visibility into how buildings use resources and to support better energy decisions. The core workflow is data collection, ESPM benchmarking, review, and reporting.
What Local Law 97 Covers
Local Law 97 sets emissions limits for many NYC buildings and creates a stronger focus on carbon performance. This means building teams need to understand not only how much energy a property uses, but also how that usage may translate into emissions exposure and future compliance risk.
How the Two Laws Connect
LL84 benchmarking data often becomes a starting point for LL97 planning. If energy usage, property details, or benchmarking inputs are incomplete or inaccurate, emissions review may also be affected. This is why clean data review is important before teams make compliance decisions.
How EnergiDash Helps
EnergiDash gives consultants and property teams a clearer way to review benchmarking reports, property-level performance, usage trends, and compliance-related indicators. This helps stakeholders understand where a building stands and what data may need additional attention.
