There is a misconception in the HVAC marketplace that needs to be addressed. Unfortunately, many people believe they only need variable speed when they have variable flow applications. This might be because the recently updated ASHRAE 90.1 2016 rules essentially do not require variable speed in constant flow applications. ASHRAE 90.1 is a minimum requirement, and if there are ways to save more energy than what is required as a “minimum”, we should absolutely be trying to save more energy than what is minimally required. Using variable speed in constant flow systems, the HVAC industry has an opportunity to save an average of 15 to 16% energy and sometimes over 50% and more.
