TLDR

• Retail and office owners are speeding up HVAC retrofit projects to meet new energy codes and avoid penalties.
• Upgrades focus on efficient rooftop units, VRF systems, and smart controls that save energy and ensure future compliance.
• Contractors and property managers should plan audits, secure incentives, and schedule installs to manage costs and risks effectively.

Retail and office building owners are speeding up commercial HVAC retrofit projects to meet new energy rules set to take effect soon. These updated building performance standards and tougher energy codes require higher efficiency and better controls for rooftop units and HVAC systems. By acting early, owners avoid costly last-minute rushes, penalties, and equipment that won’t comply with future standards. Contractors and property managers are also adjusting plans to ensure equipment choices align with upcoming requirements, protecting investments and reducing the risk of stranded assets.

What the Codes Require: BPS, IECC, and ASHRAE 90.1

Many cities are rolling out building performance standards, or BPS, over the next few years. These rules often start with energy use reporting and tune-ups. Penalties for missing targets will increase as deadlines approach. Even when you replace equipment with the same type, like-for-like swaps must meet current energy codes. For rooftop units, this means meeting higher IEER targets. IEER stands for Integrated Energy Efficiency Ratio, which measures part-load efficiency — how well equipment saves energy when not running at full capacity. More projects also require advanced controls. Demand-controlled ventilation, or DCV, uses sensors to reduce outside air when spaces have few occupants. Fault detection systems catch problems early to avoid costly breakdowns. Understanding these requirements helps you avoid penalties and plan smarter retrofits that save energy and money.

Where Demand Is Heading: RTUs, VRF, and Controls

Retail strips and low-rise offices are stepping up orders for rooftop units that meet high IEER ratings. IEER stands for Integrated Energy Efficiency Ratio, which measures energy use during partial load conditions—basically, how well the unit saves energy when it’s not running full blast. These rooftop units often come with VFDs, or variable frequency drives, which slow down fan motors to reduce electricity use when full power isn’t needed. Meanwhile, VRF systems—short for variable refrigerant flow—are gaining ground in phased retrofit projects. VRF uses refrigerant to cool or heat different zones independently, with minimal ductwork. This keeps tenant spaces open and minimizes disruption during upgrades. On the controls side, upgrades and commissioning—fine-tuning system settings—help projects quickly meet building performance standards. These controls can include sensors that adjust ventilation based on occupancy or fault detection systems that spot problems early. Together, these technologies deliver fast energy savings and often offer the quickest return on investment for commercial retrofits.

Spec to the Future: Choices That Keep You Compliant

When selecting rooftop units (RTUs), choose models with high IEER ratings. IEER stands for Integrated Energy Efficiency Ratio, which measures efficiency during typical part-load conditions. Look for units with economizers, which bring in cool outdoor air to reduce energy use. Also, choose RTUs ready for demand-controlled ventilation (DCV) sensors. These sensors adjust airflow based on occupancy, saving energy during low use.



For VRF (variable refrigerant flow) and heat pump systems, design for low-ambient heating. This means the system can heat effectively even in very cold weather. Heat recovery features are also key; they transfer heat between different zones, improving efficiency and comfort.



Controls should be open-protocol, like BACnet, allowing different devices and systems to communicate smoothly. Include fault detection to catch issues early and remote monitoring for easy system checks. Submeters help track energy use precisely, making reporting clean and accurate. These choices keep your retrofit future-proof and compliant with tightening energy codes.

Action Plan for Owners, PMs, and Contractors

In the next 90 days, start by auditing your sites. Rank them based on their energy use and risk of falling out of compliance with new codes. Pre-approve standard rooftop unit (RTU) and variable refrigerant flow (VRF) system specs to speed up future work. Over the next 6 to 12 months, focus on securing rebates and tax incentives that reduce project costs. Lock in equipment lead times early to avoid delays, and schedule installations during off-hours to minimize disruption. On an ongoing basis, track your energy use against targets to ensure compliance. Tune controls quarterly to keep systems running efficiently. Capture measurement and verification (M&V) data regularly to document performance and support reporting requirements. This planned approach helps prevent surprises, cuts costs, and keeps your properties compliant as energy rules evolve.

Key Takeaways

• Retail and office property owners are moving HVAC retrofit projects ahead of new energy codes to avoid penalties and secure incentives, shifting from reactive repairs to planned upgrades that meet rising building performance standards (BPS).
• New local energy codes require HVAC replacements to meet higher efficiency targets, including rooftop units (RTUs) with better part-load efficiency (IEER) and advanced controls like demand-controlled ventilation (DCV) and fault detection to reduce energy waste.
• Variable refrigerant flow (VRF) systems and high-efficiency RTUs with features like variable frequency drives (VFDs) and economizers are in high demand for commercial retrofits, offering energy savings and tenant comfort while supporting code compliance.
• Owners, property managers, and contractors should audit sites now, prioritize projects by code risk, secure rebates early, and plan installs off-hours to optimize budgets and avoid equipment that could become noncompliant soon.

Frequently Asked Questions

Why are retail and office owners accelerating HVAC retrofit projects?

Owners are fast-tracking HVAC upgrades to meet new local building performance standards and energy codes. Early action helps avoid penalties, reduce costs, and prevent equipment from becoming outdated or noncompliant.

What new requirements do upcoming energy codes impose on commercial HVAC systems?

New codes require higher efficiency rooftop units (RTUs) with features like variable speed motors and better controls. They also demand advanced sensors that adjust ventilation based on occupancy, plus regular reporting and system tune-ups.

How do VRF systems and controls benefit commercial retrofit projects?

Variable Refrigerant Flow (VRF) systems offer zone control and use minimal ductwork, which keeps tenant disruption low. Upgraded controls improve energy use tracking and help quickly meet building performance standards, often providing faster paybacks.

What should contractors and property managers do to prepare for these code changes?

They should audit their properties to assess code risk and energy use, select standard, future-compliant HVAC specs, and secure available rebates early. Ongoing monitoring and regular system tuning are key to staying compliant and efficient.
