A series of geothermal heat pumps from Enertech Global swept the HVAC Light Commercial Equipment category of the 2015 Dealer Design Awards, starting with the gold award winner, the TVS/TVT TETCO Commercial Series Geothermal Heat Pump.

The benefits of portables, including speedy implementation, reduced downtime, and cost-effectiveness, are continuing to gain recognition from end users. And, as end users experience these benefits and the resulting uptime, industry experts expect the portable market to continue to heat up.

Keeping people happy and cool isn’t always easy in a crunch, so it’s essential commercial contractors have the right practices in place — including access to portable equipment — to quickly restore cooling in emergency situations.

Since they don’t have to stay in one place, portable cooling units have been known to show up in some pretty unique places. Here’s a closer look at how portable units are serving in some outside-the-box applications.

After six meetings, the working group reached consensus and provided recommendations for energy conservation standards, test procedures, and metrics.

While many in the industry are pleased the DOE has taken the opportunity to work together to develop its final rule, exactly how much of the working group’s recommendation the regulatory agency will adopt remains to be seen.

Commercial building codes are mandating higher volumes of fresh-air intake than ever before. To help meet these ventilation requirements, more and more HVAC contractors and building owners are turning to dedicated outdoor air systems (DOAS). 

Manufacturers are finding innovative ways to meet and exceed expectations while creating comfortable, healthy indoor environments for building occupants.

The Cool3 indirect evaporative cooling (IDEC) unit is available in 200-, 300-, and 400-kW unit sizes. The 400-kW model offers typical annual partial Power Usage Effectiveness (pPUE) below 1.1. 

The organizing partners of the Advanced Rooftop Unit (RTU) Campaign (ARC) have announced their award winners for excellence in RTU efficiency. ASHRAE, Retail Industry Leaders Association (RILA), and the U.S. Department of Energy’s (DOE’s) Better Buildings Alliance and Federal Energy Management Program launched the campaign in 2013.
