This month’s Facility File will focus on the B2B June test for the renovation of an office building located on a major corporation’s U.S. headquarters campus. The existing HVAC system to be replaced is an antiquated hot water heating system serving baseboard radiation, unit heaters, and a rooftop HVAC unit.

Overby-Sheppard Elementary in Richmond, Virginia, needed more than an HVAC upgrade, but with tight budgets and minimal state funding, it didn’t seem likely. The 40-year-old building needed a full overhaul to provide students with a healthier, distraction-free environment.

Trane added a 3-5-ton offering to its portfolio of Foundation™ light-commercial rooftop HVAC units to provide customers with a new solution ideal for emergency replacement. The 3-5-ton unit footprint fits a common roof curb used on many existing commercial buildings. The unit can be installed without the need for an adapter, which saves customers time and money during installation.

EdmondsUSA says it has brought to America the first hybrid commercial rooftop ventilator, the ecoPOWER. Available in 3 sizes — 16-in, 24-in, and 36-in diameter throats — the ecoPOWER is a rooftop ventilator that combines gravity and motorized ventilation.

Reliable Controls has released the MACH-Pro1 and MACH-Pro2, fully programmable, BACnet® building controllers (B-BC). The MACH-Pro1 is designed for mid-sized rooftop equipment or small mechanical room applications, while the MACH-Pro2 provides expanded capabilities ideally suited to large, MS/TP rooftop equipment and mid-sized mechanical room applications.
