"Unlike products and solutions that are driven by government-sponsored utility smart grid programs, smart thermostats have remained largely in the commercial sphere, where individual energy efficiency awareness and cost savings determine purchasing decisions," says Bob Lockhart, research director with Navigant Research. "However, the combined factors of increased energy awareness, interest in home automation and security tools, and more user-friendly solutions have led to an uptick in shipments for residential smart thermostats during the past year and have revived a sense of optimism and excitement among vendors and stakeholders."
