Employee Reactions to Electrochromic Glass Windows in a Financial Office Building

Abstract

A post occupancy evaluation survey of workers in a new financial office building with EC windows was conducted. Results show that those occupants with window views responded more favorably to the effects of the EC windows than those who did not have these views. Most occupants did not report eyestrain or headache. Significantly more occupants with EC window views reported comfortable daylight, better daylight quality, better daylight satisfaction, better alertness, greater energy, relaxation and happiness at work, better sleep quality, and increase productivity. Implications of these findings are discussed.
