The Financial Case for Decennial Energy Audits

Local Law 87 requires buildings to undergo a rigorous energy audit and retro-commissioning process every ten years. While the mandate ensures baseline efficiency, forward-thinking owners leverage this process to drive substantial return on investment.

Identifying Latent Inefficiencies

Over time, even the most sophisticated building systems experience operational drift. Retro-commissioning systematically identifies these latent inefficiencies, restoring systems to optimal performance parameters.

Optimizing Existing Infrastructure

Before committing capital to major system replacements, retro-commissioning ensures that existing infrastructure is operating as efficiently as possible. Often, significant energy savings can be achieved through control logic optimization and minor repairs.

Aligning with LL97 Objectives

The insights gained from an LL87 energy audit provide a roadmap for LL97 compliance. By identifying the most cost-effective energy conservation measures, owners can strategically allocate capital to achieve both immediate ROI and long-term carbon reduction.
