HVAC contractors poised to reap benefits as Wi-Fi enabled thermostat prices drop
January 23, 2017
Despite the availability of quality Wi-Fi enabled products from leading thermostat manufacturers, a mere 10 to 15 percent of residential and light commercial installations involve such models. The primary objection: a wholesale price point that is four to five times the cost of a traditional thermostat.
When you’re looking to heat one area of a building or home with cold spots, consider spot heating options. Cold spots that need heat include areas that may not have been included when the HVAC system was installed, such as new additions or spaces that were simply overlooked.
It’s a way to reduce wasted heat and increase industrial efficiency
December 19, 2016
Combined heat and power (CHP) systems are being used by a wide range of applications to reduce the overall energy intensity of industrial systems. In some cases, such as industrial furnaces, efficiency improvements resulting from waste heat recovery can improve energy efficiency 10-50 percent.
The system uses phase change material and intelligent controls to provide cold storage savings

Viking Cold Solutions, a supplier of thermal energy storage systems, announced that a Southern California utility, along with an independent third party energy management firm, ASWB Engineering, completed a field demonstration study of the Viking Cold thermal energy storage (TES) system.
Contractors need to make sure these 10 things happen
November 7, 2016
In conjunction with the release of its latest soldering procedure, the Mechanical Contractors Association of America’s (MCAA’s) National Certified Pipe Welding Bureau (NCPWB) encourages contractors to make sure the following 10 things happen when their workers are making soldered joints.
To maximize cooling tower benefits, the appropriate tower size must be selected
October 24, 2016
Cooling towers are a relatively inexpensive and reliable way of expelling heat from a number of industrial and commercial applications. As the worldwide market continues to grow, so does the need to address the issue: How large should a cooling tower be to efficiently handle a specific application.
Arlington County, Virginia, is well on its way to a goal of 20 percent energy reduction by 2022. But the county realized it could do more — and do it quicker — if it had a modular solution that could optimize energy usage among multiple building devices.
During maintenance of steam systems, the insulation that covers pipes, valves, and fittings is often damaged or removed and not replaced. Pipes, valves, and fittings that are not insulated can be safety hazards and sources of heat loss.
Catalyst prize winners move products closer to commercialization
September 5, 2016
The U.S. Department of Energy (DOE) announced follow-on funding for the two Buildings topic winners of the Catalyst Energy Innovation Prize. The companies, Kinetic Buildings and Livable Analytics, are developing software to diagnose faulty building HVAC operation and to better understand building occupant satisfaction.
