Purpose: The majority of buildings designed over the past two decades have HVAC mechanical systems optimized using rules of thumbs that were optimal in 1937. On average, these buildings could be using 10%-30% less HVAC energy if the designers were more aware of powerful paradigm shifts that have taken place since the 1980’s. Anyone who attends this course will be given a number of effective strategies that will surely improve their very next design.
