Griffith Engineering is a proponent of using data loggers for calibrating energy models with accurate real world data. Due to GEI’s extensive experience in the Energy Management field, and with Onset products, GEI’s own, John Nott was cited several times as an industry expert in a Onset article for In the article, John speaks to the misconceptions about energy modeling, the importance of modeling accuracy for performance based contracting,  and data loggers as an integral part of energy modeling due diligence. The article concludes with this quote:

[“It’s critical to gather as much information as you can about your building,” said Nott. “The more measured, real information you have, the fewer reasonable estimates you need to make when calibrating models. While there are always components of skill and experience involved in energy modeling, the fewer estimates the modeler has to make, the more accurate the energy model will be.]
