Poor HVAC Installation Leads to Increased Energy Use

A new study from the National Institute of Standards and Technology (NIST) revealed that poor installation of air conditioning and heat pump units often leads to unsatisfactory energy performance. This research took three years to compile, with the help of surveys, field evidence, and various measurements for modeling. The most common installation errors included leaky ducts, improper refrigerant charge, oversizing of systems, and restricted…

Energy Auditing Ourselves

A short while ago I was in a meeting that centered on creating a flexible winter weatherization plan that would have a wide degree of application.  While such plans are not uncommon in the least, I was surprised to hear that we, as inhabitants, came up as a serious aspect of energy inefficiency.
