UV-C a Low Cost Solution for Improved Indoor Air Quality

Damp, humid conditions present in condenser coils, air filters, ductwork, and drain pans tend to attract microbial growth, which, left uncontrolled, can impede airflow and emit contaminants and odors into the conditioned space. One effective way of controlling microbial growth in air handlers to improve indoor air quality, reduce maintenance costs, and increase system efficiency is through UV-C, or ultraviolet light. There are two basic types of UV-C systems, coil and in-duct, which can be used alone or in tandem for increased benefit. Coil UV-C systems are generally more effective due to continual exposure and can restore as much as 40% of system capacity according to some studies. ASHRAE

Vivarium Project Success Through Collaborative Effort

Expectations were high on a recent vivarium renovation project, and contractors were challenged to collaborate closely on every level. Complicating the project were the tight quarters – small rooms, ceiling spaces, corridors, below-ground spaces – in which the HVAC and plumbing work would take place. Close coordination was required to develop a precise project schedule to prevent trade overlap in these small areas. Building Information Modeling (BIM) was utilized to determine placement of ductwork, equipment, piping and architectural features. The vivarium lead was closely involved in project planning and coordination, as well as throughout construction and quality control, and this involvem
