The Charlotte Mecklenburg School System (CMSS), the 19th largest in the U.S. with a $1.3 billion operating budget, recently decided to take action to identify school system buildings that might be exhibiting air leakage.
As common as the duct leakage problem is, it’s also very easy to go in with less-than-adequate knowledge for solving the problem in customers’ homes due to all the possible variables in play.
Even though the overwhelming evidence points to duct leakage as a main culprit behind a slew of building performance problems, little attention has been paid to addressing the situation … until now.
For those interested in energy-efficient buildings, chilled beam technology is rapidly gaining the attention here in the U.S. that it has long enjoyed elsewhere around the globe.
The National Comfort Institute Inc.’s (NCI) mission is to help its members implement HVAC and home-performance contracting through easy-to-use strategies. That mission was accomplished at its recent annual summit, where the focus was on the best practices involved with selling and installing air upgrades.
To understand airflow, one must have a firm grasp of the rules driving its characteristics and behaviors. Many of the most complicated issues a tech encounters often tie to an airflow problem, so let's look at five airflow rules that can help anyone in the industry master the airside of the profession.
