Simplified Estimation of Energy Use Intensity Based on Building Façade Features

A building’s façade is a major element that accounts for 70% of building energy performance. Compared with the internal mechanical system and operation schedule, façade features information is relatively easy to obtain from the visual aspects of a building. Instead of using traditional and complicated simulation methods, a mathematical model can be established to estimate EUI baselines based on sufficient existing building practices data. This prediction modeling approach will provide a more realistic EUI estimation tool for calculating an energy use baseline and will enable real-time energy usage monitoring and management of each targeted building.
