Prepare Your Facility To Beat The Summer Heat

HVAC technologies can result in reduced energy costs and higher occupant satisfaction during summer's peak demand days.

Prepare Your Facility To Beat The Summer Heat

With summer’s hot and humid temperatures just around the corner, now is the time for commercial buildings to make preparations to beat the heat. Heating, ventilating, and air conditioning (HVAC) costs account for 44 percent of energy consumption in all U.S. commercial buildings and a whopping 53 percent in U.S. office buildings, according to the 2012 U.S. EIA Commercial Buildings Energy Consumption Survey (CBECS) – and with warmer temperatures on the horizon, greater energy consumption is required to cool the outside air coming into a building, resulting in higher costs.

Traditionally, indoor air in commercial buildings is replaced with outside air every one to two hours to prevent high concentrations of indoor pollutants. While the process helps limit these pollutants, the high volume of outdoor air must be cooled to maintain comfortable temperatures and humidity inside the building during the summer months. At the same time, extra outside air flow to maintain air quality can result in some areas of the building getting too cold, sparking an increase in complaints from occupants. This problem is further exacerbated in buildings with higher occupant densities than they were originally designed for — a common trend with open-plan office buildings.

With this in mind, mechanical engineers, building owners, and facilities managers are now seeking HVAC technology solutions that use less outside air to ventilate a building, thereby boosting energy efficiency, saving on costs, and maintaining air quality to keep occupants comfortable.

ArcBest, an Arkansas-based logistics business, has seen a decrease in energy costs and increase in occupant satisfaction by installing innovative technologies at its facility. The solution — HVAC Load Reduction® (HLR®) technology from enVerid Systems Inc.—cleans and recycles the indoor air instead of constantly replacing it with outside air, complying with ASHRAE Standard 62.1 IAQP. In doing so, HLR technology decreases the outside air intake required to ventilate a building by 60 to 80 percent. It also reduces peak HVAC capacity, resulting in 20 to 30 percent energy savings and up to 40 percent lower utility demand charges, particularly important during summer’s peak demand days when electricity costs can skyrocket. Using less outside air extends the life of air filters, reduces water consumption, and will help postpone HVAC equipment replacement. Moreover, with HLR technology, buildings can invest in lower-capacity and less expensive HVAC systems, and benefit from decreased maintenance costs.

“I previously got calls from people that they were cold during the summer, which was a direct result of having to introduce so much chilled air into the building to meet the appropriate CO2 levels,” said Richard Rieske, Director of Corporate Facilities at ArcBest. “Likewise, they felt drafts during the winter due to all the outside air that was being used to ventilate the building. When enVerid’s HLR modules are running, our people are more comfortable.”

Solutions like the HLR system also enable increased visibility through Internet-of-Things (IoT) capabilities that provide 24/7 monitoring and management of a building’s indoor air quality, temperature, and humidity. These real-time insights into air quality and comfort allow for more proactive management of buildings to help reduce energy costs and will keep occupants comfortable and happy all summer long.
