In today’s energy-conscious world, commercial building owners and facility managers are constantly seeking innovative ways to improve efficiency and reduce operational costs. One solution that’s rapidly gaining attention in New York City and beyond is heat recovery in HVAC systems. This forward-thinking technology helps businesses repurpose waste heat — reducing energy consumption, lowering utility bills, and supporting sustainability goals.
As NYC’s premier mechanical contractor, Donnelly Mechanical is at the forefront of delivering energy-efficient solutions that help companies stay competitive, compliant, and environmentally responsible. In this blog, we’ll explore what heat recovery is, how it works, and why it’s becoming a cornerstone of modern commercial HVAC systems.
What Is Heat Recovery?
Heat recovery is the process of capturing waste heat generated during normal HVAC operations and reusing it for other heating or energy needs within a building. Instead of letting valuable thermal energy escape into the atmosphere, a heat recovery system redirects that energy to improve heating, ventilation, and even hot water supply — significantly boosting overall system efficiency.
In commercial buildings, heat recovery is most commonly integrated into systems like energy recovery ventilators (ERVs), heat recovery chillers, and heat exchangers. These technologies allow for the transfer of heat between exhaust and incoming air streams or between different building zones.
Why Heat Recovery Matters in NYC Commercial Buildings
New York City’s energy and sustainability regulations are among the most stringent in the country. Local Laws such as LL97 mandate significant reductions in greenhouse gas emissions, making it more important than ever for businesses to rethink how their buildings consume energy.
This is where heat recovery becomes a game changer. By reducing the demand for external heating sources, these systems lower overall energy consumption — helping commercial properties meet compliance targets while cutting costs.

Key Benefits of Heat Recovery Systems
1. Energy Efficiency and Cost Savings
Heat recovery systems can reduce energy usage by up to 20-30% depending on the building type and HVAC setup. By reusing heat that would otherwise be wasted, your facility reduces the need for boilers or additional electric heating — resulting in substantial cost savings.
2. Sustainability and Emissions Reduction
Sustainable building operations are no longer optional — they’re expected. Heat recovery minimizes fossil fuel use and helps lower CO2 emissions, aligning your building with NYC’s sustainability goals and supporting your company’s environmental commitments.
3. Improved Indoor Air Quality
Heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs) bring in fresh air while pre-conditioning it with outgoing air. This creates a healthier indoor environment without compromising efficiency — a win for both occupants and building performance.
4. System Longevity and Reduced Wear
Reusing thermal energy reduces the workload on traditional heating and cooling equipment. This helps extend the life of HVAC components, reduces maintenance needs, and improves long-term system reliability.
