Contractors adding duct renovation services to their repertoires can improve both the contractor’s bottom line as well as their reputation as a high-end HVAC contractor. 

Just as an infection can spread from one part of the body to another, so can contaminated air, which is why an increasing number of home and building owners are choosing to install UV products.

The DryCool™ Dehumidification System (DDS) is designed around the basic Munters desiccant dehumidification module consisting of the active desiccant wheel, a reactivation heat source, and supply and reactivation fans. 

enVerid Systems announced that it has been awarded $2.4 million through a cooperative agreement from the U.S. Department of Energy (DOE) to accelerate the deployment of the company’s new HVAC Load Reduction (HLR™) technology for buildings.

Utilizing AAF’s exclusive Impress1 pleating technology, VariCel 2+ filters combine the lowest resistance with high mechanical strength while maximizing energy efficiency.

Recognizing that the ventilation rate procedure in its IAQ standard may be difficult to apply in existing buildings, ASHRAE is proposing an alternate compliance path. Proposed addendum b is one of six addenda to ANSI/ASHRAE Standard 62.1-2013, Ventilation for Acceptable Indoor Air Quality, open for public comment until Oct. 5, 2014.

Air curtains keep unwanted cold or hot air from infiltrating an open doorway during winter or summer, respectively. The units also keep out flying insects and maintain a comfortable working environment for employees.

The smells and rich airborne aromas of fried fish, potatoes, and smoked pork at North Market are an important part of its appeal. But the market’s burgeoning IAQ problems — a byproduct of the enterprise inside — had to be resolved if the nonprofit venue and its 36 vendors were to survive.

Energy recovery ventilators (ERVs), which use the exhaust air from a building to precondition incoming air, offer many advantages for both improving IAQ and reducing energy consumption, and are one of the fastest-growing segments for improved IAQ management in buildings, says Navigant Research.
