Therefore, the execution of an energy audit is often not a linear process and is rather iterative. However, a general procedure can be outlined for most buildings. Step 1: Building and Utility Data Analysis The main purpose of this step is to evaluate the characteristics of the energy systems and the patterns of energy use for the building.

What is Energy Use Intensity (EUI)? For property types in Portfolio Manager, EUI is expressed as energy per square foot per year. It’s calculated by dividing the total energy consumed by the building in one year (measured in kBtu or GJ) by the total gross floor area of the building (measured in square feet or square meters).

A China-based cement plant used VFDs to significantly reduce its energy consumption in its dry-process kilns, responsible for production of 1.4 million tons of cement each year. Traditional damper control systems used a fixed amount of energy, so fans at the plant always ran at full capacity even when the facility wasn’t producing product
