The Benefits of UFAD Systems That You Can Take to the Bank

In the quest for more efficient and adaptable building designs, underfloor air distribution (UFAD) systems have emerged as a promising alternative to traditional overhead (OH) HVAC systems. Two comprehensive studies – one by the Center for the Built Environment (CBE) at UC Berkeley and another by Global IFS and Dynamic Systems Inc. – provide valuable insights into how UFAD systems can save on first costs while offering a variety of operational benefits.

A Range of Devices for Precise Control and Simplified Installation

In the HVAC industry, an application-specific controller is a device that comes preprogrammed with a sequence of operations for the equipment it’s intended to control. This could be anything from a boiler or air handler to a rooftop unit or terminal unit.

Promoting Healthy Indoor Air Quality in the Classroom

As HVAC professionals, one of our primary goals is to promote healthy indoor air quality in all spaces, and there are fewer applications where this is more important than in classrooms. It is estimated that approximately half of public school districts need to update or replace the HVAC systems in their schools.1

Bringing Design to Reality

Back in 2022, a mixed-use building in the Downtown East Village neighborhood of Calgary, AB, managed by the Calgary Housing Corporation, was identified as violating the city’s noise bylaws due to excessive noise emitted by its air-conditioning condensers. To address the issue, the city had initially planned to purchase and relocate new low-noise variable refrigerant flow (VRF) condensers.

System Testing to Optimize Terminal Unit Acoustics

In many commercial HVAC systems, engineers pair VAV boxes, fan-powered boxes and fan coils with duct silencers to meet the acoustical requirements of a space. While all the components are tested to industry standards – AHRI 880 and AHRI 260 for terminal units and fan coils and ASTM E477-20 for silencers – the combination of these two categories in real-world installations isn’t always straightforward.
