What if Your Office HVAC System was SMART?

“Self-Monitoring Analysis and Reporting Technology,” better known as SMART Technology, monitors and analyzes computerized equipment and lets you know when a problem arises. SMART Technology now exists in Heating, Ventilation, and Air Conditioning (HVAC) systems and it’s emerging as an extremely efficient way of saving energy (and money) for business owners.

Consider the case of a 2,500-square-foot commercial business in rural Florida built in the 1980s. The owners don’t like their AC bill, but they don’t believe the HVAC system needs an upgrade, despite spending a bundle last month when the AC cut out unexpectedly and the HVAC professional has to be called to repair the system. In the meantime, employees sweltered in Florida heat and humidity for two days until the HVAC was fixed. What could convince the owners that investing in a new system—even if a little at a time—is smart?

Self-Diagnostics

As the acronym suggests, one of the key features of SMART Technology lies in the ability to quickly self-diagnose a problem and then assist you to address it. A SMART system either would have taken care of the above issue or, at the very least, would have notified the owner earlier that service was needed—possibly even placing a call to the HVAC professional for you!

Change the Filter

Many business owners replace their AC filter annually and then forget about it for another year. But just because a filter isn’t clogged, doesn’t mean it’s efficient. A SMART system, on the other hand, informs you that your AC system is not running optimally.  The SMART system can identify problems as complex as compressor malfunction but also alert you to simpler problems, like a dirty air filter.

In fact, air conditioning filters should be changed every month no matter how often (or how little) you run the AC. The fan causes air to move throughout your business, regardless of whether the air is on or not.  Moving air eventually becomes dirty air, so replacing it each month is always a good idea.

Does the AC Need to Turn On?

Programmable thermostats save energy and money by allowing the temperature to rise in your office while you are away and then lower the temperature to maximize comfort during the peak hours when everyone is at work.

SMART HVAC systems, though, take this concept even further. A SMART system can circulate less air to an unoccupied room than would a traditional HVAC system. This conserves energy, which saves you and your business money.

Are you at work? Are you coming in early or staying late? A SMART system can be programmed to adjust HVAC usage in conjunction with your alarm system.  For example, if your HVAC system was a SMART system, it could be set up to know when you are on your way to the office. Then, say 20 minutes before arrival, it could adjust the temperature (up or down) in the office to just the way you and your employees like it.  

SMART systems have added functionality, allowing for special programming and/or linking to occupancy sensors.  Your HVAC system can be programmed to detect your presence and keep wherever you roam in your preferred comfort zone. This type of SMART functionality also can adjust the thermostat schedule to accommodate a change in business hours, such as holidays or extended/shortened hours.  The ever-growing number and type of new sensors can adjust airflow and temperature as you and your staff work rush around the office late at night, trying to meet a deadline.

Find Better Air

The newest SMART ventilation controllers address perhaps the most overlooked aspect of HVAC—Indoor Air Quality (IAQ). Let’s say an employee is microwaving some popcorn for a late-afternoon snack but accidentally leaves it in too long and it burns. Your SMART system would draw in air from outside, and only in the amount needed, to remove the odor for you—better than opening a window!

Outdoor air quality (OAQ), though, may not be the ideal solution every day. That is why the SMART system filters the air. Balance between IAQ and OAQ is key.  Without proper ventilation—defined as the exchange of outdoor air and indoor air—contaminants such as radon, formaldehyde, volatile organic compounds (VOCs) and other pollutants can build up, leading to potentially serious health problems.

Business owners should be aware of this cause and effect between ventilation and IAQ. And with an HVAC that is SMART, you are protecting your staff and your bottom line at the same time.

In Closing

SMART systems are revolutionizing the HVAC industry, controlling and monitoring equipment for maximum efficiency, as well as increased IAQ.  And the more efficient your HVAC system is, the more energy—and money—your business will save.
