TLDR

• Cities are enforcing stricter building performance standards to reduce energy use and emissions, with penalties for non-compliance starting in 2025–2026 and deeper cuts required by 2030–2035.
• Property managers must plan phased HVAC retrofits focusing on efficient chillers, heat pumps, and smart controls to meet these rules and avoid fines.
• A 90-day compliance plan includes auditing energy use, prioritizing quick upgrades, securing contractors and equipment, and setting up ongoing performance tracking.

Several major U.S. cities are tightening building performance standards, requiring large commercial properties to lower their energy use and carbon emissions. These new rules take effect with first checkpoints in 2025–2026 and full targets set for 2030–2035. Property managers and contractors must upgrade HVAC systems with higher-efficiency chillers, heat pump retrofits, advanced controls, and improved ventilation to comply. Failure to meet these standards can result in significant fines, making timely retrofits essential for avoiding penalties and protecting asset value.

BPS requirements, timelines, and penalties

Building performance standards (BPS) set limits on how much energy a building can use per square foot. This is called energy use intensity, or EUI. Some rules also cap greenhouse gas emissions from buildings. To stay compliant, building owners must benchmark their energy use every year and show progress toward targets. If they miss deadlines or fail to reduce energy use, penalties increase over time. Key programs include New York City's Local Law 97, Washington, D.C.'s Building Energy Performance Standards (BEPS), and city-specific rules in Boston and San Francisco. Each program has its own details, but all enforce clear limits and timelines. These rules make energy efficiency upgrades essential, not optional.

Who’s affected and how budgets will shift

Property managers overseeing multiple buildings face a complex challenge. They need phased retrofit plans that align with strict deadlines and performance milestones. These roadmaps help spread upgrades over time and avoid costly penalties. At the same time, tighter labor markets mean skilled technicians are in high demand. Expect longer waits for large equipment and for commissioning, which is the process of testing and validating system performance after installation. Budgeting must also factor in these delays. Financing options and available rebates can ease upfront costs. Ignoring these rules, however, risks steep fines and even lowers property value. Taking early action protects your assets and spreads spending more predictably over several years.

Retrofit playbook: systems and controls that pass

For chillers, upgrades focus on variable-speed drives, which are motors that adjust their speed to match the cooling load. This saves energy by running only as fast as needed. Heat recovery systems capture waste heat to improve efficiency. Right-sizing based on load analysis means choosing equipment that fits the building’s actual needs, avoiding oversized systems that waste energy.



Heat pump retrofits often use air- or water-source units. These systems move heat instead of generating it, making them efficient for both heating and cooling. Using low-GWP refrigerants helps reduce environmental impact. Staged changeouts spread equipment replacement over time to minimize downtime and disruption.



Control upgrades include tuning building automation systems to optimize operation. Demand-controlled ventilation uses CO2 sensors to adjust airflow based on occupancy, saving energy without sacrificing air quality. Submetering tracks energy use intensity (EUI) for specific systems, helping spot inefficiencies. Continuous commissioning means regularly checking and adjusting systems to maintain performance over time.

90‑day plan to de‑risk compliance

Start by auditing your buildings with 24 months of utility data. This helps benchmark your energy use intensity (EUI), which measures energy used per square foot. Then, run a gap-to-target analysis for each site to see where upgrades are needed. Next, scope quick wins like adjusting setpoints, fixing schedules, and using economizers—these use outside air to cool for free. Focus Phase 1 retrofit designs on sites facing the highest fines. Finally, execute your plan by pre-qualifying installers and reserving long-lead equipment early. Set up a measurement and verification (M&V) plan to track performance and create a reporting calendar. This keeps projects on schedule and ensures you meet evolving standards without surprises.

Key Takeaways

• Cities are enforcing strict building performance standards (BPS) that limit energy use and greenhouse gas emissions in large commercial buildings. These rules include real fines and start with checkpoints in 2025–2026, aiming for deeper carbon cuts by 2030–2035.
• Commercial HVAC retrofits will focus on upgrading to high-efficiency chillers, heat pumps, advanced controls, and improved ventilation to meet these standards and avoid penalties.
• Property managers with multiple sites need to create phased retrofit plans aligned with milestones, considering longer equipment lead times and tight labor markets. Financing and rebates can help reduce costs, but delays risk fines and asset value loss.
• A 90-day compliance plan includes auditing utility data, identifying quick energy-saving wins, designing phased retrofits, pre-qualifying installers, and establishing a measurement and verification system to track progress and stay on schedule.

Frequently Asked Questions

What are building performance standards (BPS) and why are cities updating them?

Building performance standards (BPS) are rules that limit how much energy or greenhouse gas large buildings can use or emit. Cities are updating these standards to meet carbon reduction goals by 2030 to 2035, with checkpoints starting in 2025, pushing building owners to upgrade HVAC systems and controls.

Who needs to comply with these new city BPS rules?

Property managers of large commercial buildings, especially those with multiple sites, must comply. They need to plan phased retrofits to meet energy and emissions targets or face financial penalties and possible devaluation of their properties.

What types of HVAC upgrades are required to meet the new standards?

Upgrades include installing higher-efficiency chillers, retrofitting heat pumps, adding advanced building controls, and improving ventilation systems. These changes help reduce energy use intensity (EUI), which is the energy consumed per square foot.

What steps can building managers take now to prepare for compliance?

Managers should start by auditing utility data for the last 24 months to benchmark energy use. Then, identify quick wins like adjusting setpoints and schedules. Finally, they should plan phased retrofits, pre-qualify installers, and set up measurement and verification processes to track progress.
