Navigating through the maze of available options, such as variable refrigerant flow systems, can be daunting, but understanding how these systems harness natural warmth from air or ground sources to support and help heat buildings is key. This knowledge of refrigerant not only empowers you with choice but also aligns your operations with contemporary environmental standards.
Commercial heat pump systems harness the principle of heat transfer using refrigerant. They move warmth from one place to another. In winter, they extract heat from the outside air or ground using refrigerant and bring it indoors. During summer, this process reverses.
Heat pumps do not generate heat; they relocate it. This makes them highly efficient compared to traditional heating methods that burn fuel inside a building, utilizing refrigerant. For example, a commercial building can use a ground-source heat pump with refrigerant to pull warmth from the earth in colder months.
The core of these systems lies in their refrigerant cycle. This cycle involves evaporation and condensation processes using a refrigerant substance.
Firstly, the refrigerant absorbs external heat as it turns into gas during evaporation. Then, as gas compresses and heats up further, it releases this energy inside when returning to liquid form during condensation. A simple analogy is how sweating cools our body; evaporation takes away body heat.
This cycle allows for both heating and cooling within one system by reversing its direction—a versatile feature for commercial spaces with varying temperature needs throughout the year.
Electricity powers these systems—making them reliant on electrical sources but also allowing integration with renewable energy solutions like solar panels.
A key advantage here is that electricity can be cleaner than fossil fuels if sourced from renewables. Plus, electric-powered systems often have lower operational costs over time due to fewer moving parts leading to less wear and tear.
Commercial heat pump systems come in various models. Air-source pumps are common. They transfer heat between your building and the outside air. These pumps are often less expensive to install.
Businesses in mild climates benefit from them. However, efficiency can drop in colder weather. Installation is simpler because they don’t need underground components.
Water-source heat pumps use water bodies or a flow of water for heating and cooling. This type is ideal when there’s access to a lake, river, or even a well-designed man-made loop system.
They work well where temperatures remain consistent near water sources. The installation may be more complex than air-source types but offer higher efficiency levels.
Lastly, ground-source, also known as geothermal heat pumps, utilize earth’s stable temperature. They’re suitable for areas with extreme climate changes due to their reliable performance year-round.
The initial cost is higher due to excavation or drilling required during installation. But they save money over time with low operating costs and high durability.
Ground-source models can be an investment that pays off long-term for commercial properties looking for sustainable options.
Commercial heat pump systems offer significant energy efficiency. They use less electricity than traditional HVAC systems. This leads to notable cost savings in the long run. Businesses see a decrease in their energy bills due to the efficient transfer of heat rather than generating it.
Reduced operational costs from lower energy consumption.
Long-term financial benefits through efficient performance.
Heat pumps work by moving heat into or out of a building. This process is more energy-efficient compared to creating warmth or cold air from scratch, like many conventional systems do.
These systems have another advantage: they emit fewer carbon emissions. By relying on electricity and not fossil fuels, commercial heat pumps are cleaner for our environment. Lower carbon footprints make these systems ideal for eco-conscious businesses.
Less reliance on fossil fuels.
Contribution to a greener planet with reduced greenhouse gases.
Using renewable energy sources can further enhance this benefit, making commercial heat pump systems an environmentally responsible choice for heating and cooling needs.
Versatility is key with commercial heat pumps as they provide both heating and cooling solutions. The same system that keeps you warm in winter will cool you down in summer months. This dual functionality ensures comfort no matter the season without needing separate units for each purpose.
Businesses enjoy consistent indoor climates all year round with just one system installed:
Simplified maintenance due to single-system management.
Adaptability across seasons enhances workplace productivity and customer satisfaction.
The versatility also means spaces can be quickly adapted based on changing weather conditions or different uses throughout the day, offering maximum flexibility for commercial settings.
Variable Refrigerant Flow (VRF) systems are a game-changer in commercial spaces. They allow precise temperature management for different areas or zones. This means that each room can have its own climate settings, independent of others.
A conference room full of people might need cooling while an empty office needs less air conditioning. VRF systems make this level of control easy. They’re smart, adjusting to the specific needs of each zone.
Energy savings with VRF technology come from its partial load operation. Unlike traditional systems that run at full capacity all the time, VRF units work only as hard as necessary.
When only a few rooms require heating or cooling, the system uses less energy than if it were servicing the whole building. It’s like having many small units rather than one big one—each working efficiently on its own task.
Commercial heat pump systems now offer customizable temperature zones. This means a single system can control different areas independently. For example, an office building could have separate zones for each floor or department.
Businesses benefit greatly from this feature. They ensure comfort where it’s needed most, without wasting energy elsewhere. Plus, employees enjoy a workspace tailored to their thermal preferences.
Enhanced comfort is another big plus of zoning with heat pumps. Each zone has its own settings for heating or cooling. As a result, people experience the right temperatures in their immediate spaces.
Imagine walking from a warm lobby into your cool personal office on a hot day—pure relief! This targeted approach not only boosts morale but also productivity.
Energy efficiency is crucial in today’s world, and zoning plays a key role here too. By focusing on occupied areas only, businesses save significant amounts on utility bills.

In today’s real estate industry, developing and retrofitting buildings to be more sustainable and energy efficient is more important than ever. The urgency to decarbonize is being driven by local, federal, and global commitments to drastically cut energy use and reach net zero emissions.
Systems that heat, cool, and provide electricity to buildings are critically important parts of the decarbonization journey, and they are key to achieving net zero pledges. Among the mechanisms being used to do so, the heat pump has emerged as one of the most popular tools for building owners to slash energy use, cut down on energy costs, and improve indoor environments.
In a new report by ULI’s Randall Lewis Center for Sustainability in Real Estate and ASHRAE, Pumping Up Sustainability, experts break down myths around heat pumps. These experts establish a clear case for why the technology is crucial to reaching sustainability goals and is good for building owners’ collective bottom line. Inspiration for the report came from ULI’s Net Zero Imperative Technical Assistance Panels, a series that continually touches on the importance of electrification as a key to the industry reaching net zero goals. A crucial part of electrifying buildings is installing HVAC systems that do not run on fossil fuels—and here, heat pumps play a significant role.
A heat pump is part of an HVAC system that can heat or cool spaces. Heat pumps efficiently move heat from one place to another, depending on where it’s needed in a building. Many run on electricity instead of gas and use a compressor to move heat in the desired direction for thermal comfort. The main difference between a traditional air conditioner and heat pump technology is that a heat pump has a reversing valve, which lets it heat a space as well as cool it. In essence, a heat pump functions like an air conditioner in reverse, by using refrigerant to warm a building instead of keeping it cool.
The two main kinds of heat pumps are air source and ground source. In some cases, heat pumps are paired with traditional heating systems, such as gas furnaces, a combination often referred to as a hybrid heat pump. During the colder months of the year, heat pumps pull heat from the cold outdoor air and transfer it indoors, whereas in warmer months, the systems pull heat out of indoor air to cool building spaces. Because heat pumps, unlike traditional HVAC systems, typically do not burn fossil fuels, these systems are more environmentally friendly and a sustainable alternative for building owners looking to move away from dependence on fossil fuels.
Focusing on heating and cooling in decarbonization efforts is important. According to an article in the World Economic Forum, 15 percent of global carbon emissions comes exclusively from heating and cooling of buildings. To meet net zero targets, buildings eventually need to be powered by renewable energy sources only.
ULI and ASHRAE’s report found that heat pump tech is becoming an increasingly scalable solution on the commercial real estate industry’s path to fully electrifying commercial buildings. By making this transition, owners could slash emissions related to heating and cooling buildings by as much as 20 percent—according to data from McKinsey—which could create healthier and more comfortable environments for building occupants, and pass along energy savings to tenants.
Heat pumps are a buzzy subject in the real estate industry, but a clear understanding of what they can and cannot do remains to be reached. Although the technology has existed for quite some time, now that these systems are trending in a big way, myths and outdated information about the limits of heat pumps persist, according to experts. That condition could prevent a wider adoption of these systems.
“A lot of the myths [connect to] legitimate concerns, but there’s always nuance around [them],” says Stet Sanborn, a vice president in the mechanical engineering division at SmithGroup, an architecture and engineering design firm with 20 offices nationwide. Sanborn, who is the mechanical discipline lead for the firm’s San Francisco office, is also a part of ASHRAE’s Task Force for Building Decarbonization.
Among the most common downsides that come up in conversations about heat pumps is the notion that this technology doesn’t work in cold climates. Although that may be true for some heat pumps, Sanborn points to a “whole class” of heat pumps that are specifically designed to work in cold climes. As the report spells out, the highest per capita installation rates of heat pumps are in areas with colder climates.
Another common myth suggests that heat pumps are available only for single-family homes or smaller commercial buildings and don’t work for high-rise or industrial properties. Nonetheless, there are various heat pumps on the market that can work for asset classes across the real estate spectrum and that can be used not only in new construction but also in retrofits of older buildings.
Heat pumps have been widely adopted around the world, especially in such places as Japan, where 90 percent of housing stock is multifamily and already has the heat pump installed. In , more heat pumps were sold in China than in any other country. Although the U.S. still lags Europe and other places in heat pump adoption, many owners are seeing the benefits clearly.
Jonathan Arnold, principal at the Kansas City–based firm Arnold Development Group, focuses his firm’s work on sustainable, mixed-use, urban developments. One of the group’s most well-known projects is Second + Delaware, a six-story, 276-unit residential building that is one of the largest Passive House buildings in the world. That project, along with many others Arnold has developed, uses heat pumps.
Even as Arnold experienced the tech’s cost savings and enhanced energy efficiency firsthand, he found that choosing the right kind of heat pump system for a project is key. He urges architects and developers to explore options when considering the technology. “It has the potential of having such an impact financially, for thermal comfort, indoor air quality …. You wouldn’t find developers not caring about finishes in the kitchen or views outside the building, because they matter, they drive value,” Arnold says. “I think the market is waking up to the fact that those things are important, and our industry should pay attention and not just choose the cheapest option possible.”
Not only are heat pumps hugely important on the path to net zero, they bring other benefits to owners and tenants of commercial buildings: air quality and occupant comfort improve, a building’s operational efficiency increases, and the technology can help owners meet regulatory requirements and qualify for such government incentives as rebates and grants.
For professionals in various heat pump–manufacturing, engineering, and HVAC spaces, education on the abilities of heat pumps is a top priority. Reports such as the ULI and ASHRAE study are among the key ways these sectors are doing so, but more work is needed. Still, much progress is being made, and that’s encouraging to professionals at the forefront of sustainability efforts.
