The air quality isn’t too good here, either) That’s where the air quality is so bad that it affects your ability to think properly or effectively. In his recent Wall Street Journal article Why Office
by Joseph G. Allen — Harvard Business Review How often do you consider the air quality in your office and how it affects employees and their productivity? Chances are it’s not often. There is a tendency to assume that, as long as commonly used standards for air quality are met, it won’t be an issue.
By Bob Krell, President, IAQ Technologies, Inc. Few building owners or facility managers would argue whether HVAC (heating, ventilating, and air conditioning) systems are important factors in a building’s indoor environment. After all, it seems only logical that the systems relied upon to condition and transport air through a facility would play a key
The 2016 update to ASHRAE Standard 62, Ventilation for Acceptable Indoor Air Quality, has changes that affect the indoor air quality procedure, laboratory exhaust and demand control ventilation. The standard sets minimum ventilation rates and other requirements for commercial and institutional buildings. Multifamily residential dwelling spaces have been removed from 62.1 are now covered under
The Center for Disease Control (CDC) estimates that 2 out of 3 indoor air quality problems involve the HVAC system – both the heating and air conditioning side of the equation as well as the more obvious component involving ventilation. In fact, an overwhelming amount of IAQ problems can be traced directly to duct leakage.
GrayWolf Sensing Solutions of Shelton, CT, USA, introduces the new AdvancedSense BE, a rugged, simple-to-use, multi-parameter environmental meter. This purpose-built instrument is suited for both walk-thru surveys and for trend-logging over hours/days/weeks/months. Use it for Indoor Air Quality (IAQ), Industrial Hygiene (IH), Facility Management (FM), Heating Ventilation & Air Conditioning (HVAC) and other environmental applications.
By Bob Krell, CIEC, LEED-AP This article is about DUCT cleaning, not duck cleaning! OK, I just couldn’t resist the graphic puns, but after over 27 years of being involved in the HVAC hygiene industry, I think it’s fitting. So, just what IS duct cleaning, and why should you be considering it as part of
Homes are being more tightly built than ever to prevent air leakage and promote energy efficiency. High humidity levels can encourage mold growth, and indoor pollutant levels are commonly two to five times higher than outdoors, compromising health. The new Zehnder ComfoAir 70 Energy Recovery Ventilator (ERV) offers a balanced ventilation solution for new and
Assessment, Cleaning, and Restoration of HVAC Systems (ACR The NADCA Standard) is unique in that it is a performance standard that also provides minimum procedural requirements. This Standard has evolved from procedural-based guidelines, standards of care, and research originating from the National Air Duct Cleaners Association (NADCA), along with associated organizations. It is based on
