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.

5 Top Trends in Commercial HVAC

Jan 09, 2019

As both our internal and external environment changes, the HVAC industry also changes and develops new technologies in heating and cooling to meet new improved energy efficiency standards. For example, 30 years ago, HVAC systems consisted of single-stage motors and mercury thermostats that maintained a steady temperature 24 hours a day unless the dial was turned up or down. Today, we have programmable thermostats that allow multiple temperatures to be set, depending on the time and day of the week, and we have variable-speed motors that can decrease or increase, depending on cooling or heating needs. The 2019 HVAC trends are forecast to involve better HVAC connectivity and data as well as improvements in green HVAC technology.
