What if you could say goodbye to the uneven temperatures, drafty rooms, and noisy vents associated with traditional HVAC systems? With Underfloor Air Distribution (UFAD), you can. This alternative heating and cooling system delivers precisely conditioned supply air through a network of hidden ducts beneath your floor, ensuring consistent temperatures throughout your space with whisper-quiet operation. More than that, with the improved indoor air quality of a UFAD system, you can breathe easier while enjoying increased comfort and energy efficiency.
Effective air distribution is the cornerstone of a comfortable indoor environment. It’s key to maintaining consistent temperatures, ensuring proper ventilation, and optimizing energy consumption.
Most people are familiar with traditional HVAC air distribution systems, which use ceiling or wall-mounted ducts to distribute conditioned air from a central heating or cooling unit to each room. Ceiling-mounted vents then release the air downwards. While these systems are common in homes and commercial buildings, they can create uneven temperatures, causing uncomfortable hot or cold spots for building occupants.
Underfloor air distribution is a modern alternative to traditional overhead systems, delivering air through a network of ducts installed beneath the floor. Conditioned air exits through floor-level diffusers, rising naturally and circulating throughout the space. An underfloor air distribution system’s approach reduces energy waste by focusing airflow in occupied zones rather than the space close to the ceiling.
Air distribution directly affects indoor air quality by removing pollutants, allergens, and excess moisture, creating a healthier environment. For property owners focused on tenant satisfaction and energy savings, UFAD HVAC offers an efficient solution, enhancing comfort while reducing costs.

Underfloor Air Distribution takes a different approach to heating and cooling by using the space beneath your floor and conditioning air from the bottom up. This method provides the same comfortable environment while maximizing energy efficiency. Let’s take a closer look at how this heating and cooling system works.
Underfloor air distribution begins with a raised access flooring system. This creates a concealed space, or plenum, between the structural floor and the walking surface. These underfloor plenums house the key components of the UFAD system.
A network of ducts is installed within the plenum. It carries conditioned air (heated or cooled) from a central air handling unit to different rooms.
Strategically placed diffusers or vents are integrated into the raised floor. These diffusers release conditioned air into the occupied zone. They can be adjusted to control airflow and temperature in specific areas.
The conditioned air delivered from the floor rises naturally, creating a comfortable and consistent temperature at ground level. As the air warms or cools, it’s drawn back into the system through return air grilles typically located in the ceiling. This creates a continuous cycle of fresh, comfortable air.

An underfloor air distribution system offers a range of advantages that make it an increasingly popular choice for commercial buildings. Here are some key benefits:
Enhanced Energy Efficiency: A UFAD system focuses on conditioning the occupied zone, reducing energy waste by minimizing airflow to unused ceiling space. This targeted approach can significantly lower energy consumption and operational costs.
Improved Occupant Comfort: UFAD ensures consistent temperature distribution with upward airflow, reducing drafts and stratification for a more comfortable indoor environment. As a result, building occupants can be more focused and productive.
Quieter Operation: UFAD HVAC systems typically require less fan power due to the natural buoyancy of air as it rises. This makes UFAD systems quieter, ideal for a peaceful and productive workspace.
Superior Indoor Air Quality: UFAD’s upward underfloor ventilation pattern can improve indoor air quality by minimizing dust recirculation. As the air rises from the floor, it carries pollutants upwards and away from the occupied zone, improving air quality.
Flexibility in Office Layout: Without bulky overhead ductwork, a UFAD system allows for flexible office layouts, making workspace reconfigurations easier.
Sustainability and Green Building Certifications: UFAD reduces energy use and supports green building goals. Installing a UFAD system in your building can contribute toward green building certifications, such as LEED (Leadership in Energy and Environmental Design).

Choosing the right air distribution system for your commercial property can feel like navigating a maze of acronyms and technical jargon. But don’t worry, this section breaks down key differences between underfloor air distribution and traditional overhead HVAC air distribution systems in a clear and approachable way.
| Feature | UFAD | Traditional HVAC |
| Installation | ✖️ Requires raised access flooring; more complex installation | ✔ Simpler installation, typically in ceilings or walls |
| Cost | ✖️ Higher initial investment | ✔ Lower upfront cost |
| Maintenance | ✖️ More challenging due to underfloor components | ✔ Generally easier access to maintenance |
| Energy Efficiency | ✔ Higher efficiency due to targeted air delivery | ✖️ Lower efficiency due to conditioning unoccupied space |
| Comfort | ✔ More consistent temperatures, fewer drafts | ✖️ Uneven temperatures and drafts |
| Indoor Air Quality | ✔ Improved air quality due to upward airflow | ✖️ Recirculates contaminants more easily |
| Flexibility | ✔ Greater flexibility in office layout and design | ✖️ Limited design options due to ductwork |
| Noise Level | ✔ Quieter operation | ✖️ Noisier due to higher fan speeds |
UFAD truly shines in large, open-plan offices where maintaining consistent temperatures and optimal air quality across the entire space is crucial. It’s also particularly well-suited for buildings with high ceilings, as it avoids wasting energy on conditioning the air above occupants’ heads.
If you change your office layout frequently, underfloor ventilation offers flexibility without the constraint of fixed ductwork in the ceiling. For organizations with strong sustainability goals, UFAD’s energy efficiency and indoor air quality benefits can contribute to achieving green building certifications.
A traditional air distribution system suits smaller spaces where UFAD’s complex system may be unnecessary. In older buildings with existing infrastructure, retrofitting a UFAD system can be challenging and costly, making traditional HVAC the more practical option. For projects with tighter budgets, the lower upfront cost of traditional HVAC air distribution systems can be a significant motivating factor.
Designing a successful UFAD system requires expertise and experience. It’s highly recommended to consult with trusted HVAC specialists who can assess your specific needs, conduct thorough calculations, and create a customized design that optimizes comfort, efficiency, and indoor air quality. Working with professionals ensures that your underfloor air distribution system delivers the desired results and a truly comfortable and sustainable building environment.

Ready to experience the comfort and efficiency of UFAD? Great! Before you get started, there are a few things you need to know about proper installation. This section will guide you through the process, from the initial assessment to the final handover, and provide a comprehensive checklist for keeping your underfloor air distribution system running smoothly.
A typical underfloor ventilation installation for a commercial property follows these steps:
Reach out to experienced UFAD HVAC providers like LG Home Comfort to discuss your needs and explore possibilities.
An LG Home Comfort contractor inspects your property and assesses your property’s suitability for underfloor ventilation, considering factors like ceiling height, floor construction, and existing infrastructure. They’ll identify the best locations for underfloor ducts, diffusers, and return air grilles, taking into account specific considerations for commercial properties.
Based on the assessment, HVAC specialists design a customized UFAD system, including ductwork layout, diffuser selection, and zoning configuration.
If a raised access floor isn’t already in place, it will be installed to create the plenum space for the underfloor ventilation components.
The underfloor ventilation ductwork is installed within the plenum, followed by the placement of floor diffusers in the raised floor panels.
The UFAD system is connected to the central air handling unit, ensuring proper airflow and control.
To minimize disruption of your operations, use a phased approach. Installing the underfloor air distribution system in sections or during off-hours reduces the impact on day-to-day operations.
