St. James United Methodist Church’s mixed-use nature required a versatile comfort fix
February 8, 2016
Because of the mixed-use nature of church buildings, broad range of room sizes, and long vacancy periods punctuated by short stints of high occupancy, many congregations, especially those exploring retrofit projects, have turned to mini-split heating and cooling technologies in the past decade. More recently, commercial VRF systems have added even more capability, simplicity, and efficiency to the already vast number of possibilities offered by ductless technology.
The J-II single-phase variable refrigerant flow (VRF) serves ambient heating and cooling applications in a 3- to 5-ton range and can be used for large residential and small commercial installations.
Everything is bigger in Texas — at least that’s how the idiom goes. It holds true for Samsung HVAC, which held its annual sales meeting at The Gaylord Texan in Grapevine, Texas. The event drew more than 500 attendees — drastically more than attended last year’s event.
When it comes to heating and air conditioning in the home, advancements within the components themselves are making units more energy efficient than ever. HVAC systems are increasingly communicating between the indoor and outdoor controls while also reducing heat loss and maximizing dehumidifying processes.
LG VRF systems provide comfort while maintaining building’s historic integrity

When Hampton by Hilton approached the building’s then owners with hopes of transforming it into a hotel, the hotel chain was met with the daunting task of undergoing a full renovation of the historic space that had been unoccupied since 2004.
LATS CAD 2 software integrates with AutoCAD to allow engineers to arrange and validate LG variable refrigerant flow (VRF) systems directly into their computer-aided design (CAD) drawings.
Over 50,000 feet of refrigerant piping needed to be carefully insulated

Many Clemson fans would gladly sit on a wooden crate and cool themselves with a hand fan in order to watch a game at legendary Memorial Stadium. Others require a more luxurious game day experience. For these more affluent fans, Clemson has completed a $25 million renovation including a variable refrigerant volume (VRV) system.
These three working examples show how VRF technology helped a historical building never designed for air conditioning reach Leadership in Energy and Environmental (LEED) Gold certification, a high-rise project meet Title 24 standards, and a convent save $80,000 a year on energy costs.
While the U.S. ranked fourth in the top 10 markets, it’s on the upswing. VRF continued to gain market share from small- to medium- size chillers in 2014, according to the report, and BSRIA expects market growth to continue at an 11 percent compound annual growth rate (CAGR) between 2013 and 2018.
Johnson Controls Inc. (JCI) recently opened the doors to a 12,600-square-foot training facility devoted to increasing the industry’s awareness of VRF technology, equipment, and operation. The center, which officially opened in July, boasts a hands-on lab, two 25-person-capacity classrooms, audio/video conferencing capabilities, and a full curriculum to help HVAC contractors and sales professionals deliver quality VRF solutions.
