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.

Energy represents the single fastest-growing operating cost in the lodging industry, according to the Department of Energy (DOE). Decisions on guest room equipment amplify by dozens or hundreds in a single property. The mechanical systems work on such a scale that any amount of waste can add up to a significant financial loss or missed opportunity while, on the other hand, minor savings in one area can accumulate to an appreciable gain.

Many of the calls I receive about goofy static pressure readings typically tie into one of five issues. Let’s look at these issues and how you can be sure they don’t affect your measurements.

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.

The first reason not to measure static pressure is because hooking up a refrigeration manifold to the system tells you everything you need to know. Don’t worry about the fact that this practice often leads to leaks, can introduce non-condensables, and can cause potential refrigerant contamination.

Energy standards and feedback from the field were the impetus behind the Delta Breez GreenBuilder GBR80HLED by Delta Electronics, the gold-winning product in the 2018 Dealer Design Awards for the Ventilation Products category.

In order to understand the foundational principles of duct sizing, a thorough study of ACCA Manual D is a great place to start.

Due to advancements in technology and efficiency and the swelling consumer awareness, ductless equipment continues to be one of the fastest-growing sectors throughout the HVACR industry.

Several months ago, I wrote a Duct Dynasty article titled “Four Steps to Optimize a Duct System.” Since then, I’ve received numerous requests to expand on the simple calculations I mentioned that can help you estimate room airflow with a customer’s input.

Poor ventilation leads to water damage, mold, and other issues in the home that cause respiratory problems, allergies, and other illnesses for the occupants.
