The purpose of this article is to study the impact of seven different window systems on overall energy consumption of educational buildings. In particular, four of the windows are non-traditional liquid crystal base, namely 1) Tunable, 2) Broadband Type 1, 3) Broadband Type 2, and 4) Broadband Type 3. For the purpose of simulation, a LEED Gold certified building located at a major university in the U.S. was modeled, benchmarked, and calibrated. Then several scenarios according to window choices haven been tested, both in actual and different climate zones. The results show, Broadband Type 2 and Type 3 can make a significant impact in reducing building energy consumption. Their contribution is higher for projects located in hotter climates.
