In HVAC systems, there are many different parameters that are commonly measured for system performance or building comfort. Some of the most commonly measured HVAC system parameters are temperature, air velocity, humidity and static pressure. Of those parameters, static pressure is extremely important in terms of system performance. Static pressure indicates how hard the HVAC system has to work to move air through the building or how much resistance to flow exists. The higher the static pressure, the harder the system has to work to move air through the building. Continue reading “Static Pressure in HVAC Systems”

As cities around the world continue to grow, the need to fit more parking and loading dock capacity into smaller spaces is essential for new municipal and commercial building plans. For personal vehicles, many designers turn to enclosed parking garages to fit as many vehicles in as small a space as possible, or to mixed-use structures that combine a parking garage with work or living space in one building. For commercial traffic, loading dock operators are designing docks and material handling systems to service shipping vehicles as quickly as possible.

Many people think that we get cold and flu viruses more often in the winter due to the cold temperatures outside; however, this can actually be attributed to the fact that we are inside more, thus being exposed to higher concentrations of pollutants. Poor indoor air quality can cause what has come to be known as sick building syndrome.
