Your Building HVAC Has an Important Role in Protecting Against COVID-19

Apr 15, 2020

According to the EPA, indoor air can be as much as 2 to 5 times more polluted than the outdoor air, and infants, children, the elderly and those with preexisting conditions, like COPD and asthma, can be more susceptible to the effects of indoor air pollution than others. Part of the reason that modern buildings tend to trap pollutants is because they are increasingly designed to be air-tight due to energy-efficiency standards and the desire to use as little electricity, natural gas and propane or heating oil as possible.

What Commercial Building Owners Need to Know about Freon Law Change

Jan 29, 2020

Have you heard about the upcoming freon law change? If you aren’t, you should know that R-22, which is known by the brand name Freon, will be illegal in the United States as of Jan. 1, 2020.

How Does HVAC Maintenance Impact Energy Savings?

Jun 26, 2019

Have you noticed an increase in your HVAC costs? While HVAC energy usage isn’t itemized on utility bills, most buildings spend about 38 percent of their total energy usage on heating and cooling costs, according to the Department of Energy. The rest of the energy usage breaks down into lights, security, running mechanical equipment, like elevators and escalators and running computers and office equipment. Therefore, when you see a sudden increase in your energy usage and your bill, it’s reasonable to assume it’s due to your HVAC system not operating efficiently, and the number one reason HVAC systems fail to run efficiently is due to lack of maintenance. In other words, your lack of HVAC maintenance negatively impacts your energy savings and bottom line.

What Is a Dedicated Outdoor Air System (DOAS) for a Commercial Building?

Apr 18, 2019

With increasingly strict energy efficient guidelines and a continuing push to make every building as energy efficient as possible, modern buildings are increasingly airtight. This means that indoor and outdoor air do not mingle aside from the occasional and briefly opened door. Because of this, modern buildings can trap air pollutants, moisture and other particulate matter, which decreases the indoor air quality and can lead to sick building syndrome. One of the ways to combat excess moisture and indoor air pollutants is to install a Dedicated Outdoor Air System (DOAS) that does nothing but filter outdoor air and bring it into the building.
