Product Guide Tools We Use: Clamp Ammeter A tool commonly found in an electrician’s toolbox can also be useful during energy audits and building investigations By RANDY WILLIAMS | February 20, 2026 More Product Guide Modern Mill Now Offers Its Rice Hull–Based ACRE Siding and Trim in Factory-Finished Options Tools We Use: ACIN FlowFinder Diagnostic Tools We Use: Portable and Wearable Ambient-Gas Monitors Introducing the SWERVAIR Energy-Recovery Ventilator Full disclosure: I’m both an energy auditor (Building Analyst Technician and Building Analyst Professional) and a licensed journeyman electrician. That training provides a level of knowledge—and the confidence—to work safely around live electrical equipment. Electricity can be dangerous. If you’re not trained, don’t work on energized systems.More than half of the energy audits I perform start with the same complaint: our electric bill is too high. Sometimes the cause is building-related—a leaky enclosure or inefficient heating and cooling system. At other times it’s much simpler: a piece of equipment using more electricity than expected. Electric space heaters and dehumidifiers are a couple of common problem appliances I find.Measuring electricityThere are several ways to measure electrical consumption. Plug-in meters, such as the Kill-A-Watt, work well for cord-and-plug appliances. Some newer load centers or service panels and smart breakers—such as systems from SPAN and Leviton Manufacturing—track usage in real time and ...
