An energy audit is an inspection and analysis of how a building uses energy. To get an accurate analysis, tools are needed to perform testing. You would think that a blower door and thermal imaging camera would be my most commonly used tools during an audit, I do use them often, but there are a couple I used more. This posting is all about my energy auditing toolbox. Continue reading “Energy Audit-Tools of the Trade”
