Electrochromic Window Testbed

Abstract

Electrochromic (EC) windows are being used to reduce energy consumption and increase occupant comfort in buildings. EC technology allows the user to control the tint level of the window by applying a voltage across the electrochromic layering on the inner pane. The level of tint directly relates to the amount of solar radiation and light transmission, enabling control over solar heat gain and natural light levels. Current EC window technology lacks a control system that integrates the variable tint levels with the building management system (BMS) which controls Heating, Ventilation, Air-conditioning, and Lighting. This project involves developing a quarter-scale model of a typical office in a commercial building in order to evaluate the effect of EC windows on a building
