How HVAC affects air pressure in buildings is determined by a few factors. It’s especially important to consider the impacts of both balanced and degraded HVAC systems. The HVAC system is designed to keep a building comfortable by regulating the temperature, humidity, and air quality inside. One important aspect of HVAC systems is air pressure. […]

Building pressurization is the difference in air pressure between the inside and outside of a building. There are three types of pressure that we typically talk about: positive pressure, negative pressure, or stack pressure, and each has an affect on indoor air quality. Positive pressure occurs when there is more air coming into the building […]

Indoor air quality is a top concern of building managers. In fact, it’s a concern of all stakeholders as it involves the health and safety of building occupants as well as the company’s bottom line. Poor IAQ, resulting from ventilation issues or water intrusion, poses a threat. Virus transmission is another cause for concern, however, […]

Many of us think of old buildings as drafty, dusty places and as potential sources of mold and mildew. Therefore, it makes sense that indoor air quality in these older structures would concern both building managers and occupants. However, new buildings IAQ is just as important. The Importance of New Buildings IAQ We spend the […]

Providing a safe, healthy environment for workers requires proper indoor air quality. The same is true for visitors to retail outlets, medical clinics, gyms, and restaurants. It’s also true for homes and apartment buildings. When problems arise that affect the integrity of the building envelope, IAQ suffers. Therefore, facilities managers need to understand how the […]

  If you suspect a water intrusion issue in a building you own or manage, it’s important to get clearance testing for mold. This process is a part of creating a safe work environment for staff and visitors to a building. It also assures building occupants that their well-being is important to management. Testing either […]
