Smart Thermostats Helping To Grow Home Energy Management Market

Lauren Callaway — July 31, 2015

Home energy management has come a long way in recent years, and smart thermostats have been a significant portion of its increasing technology adoption.  Nest, ecobee, and Honeywell (to name a few) have created iconic and effective tools that have proven results for regulating the amount of energy used to heat and cool homes and small commercial spaces.  Some would suggest that these devices are well on their way to being adopted as mainstream (and not niche) tools for home energy management.

According to a market research report released this month by Parks Associates, the market for smart thermostats is expected to have composed 40% of total thermostat sales in the United States in 2015, which is estimated at around 10 million devices annually.  In 2017, greater than 50% of all thermostats will be smart thermostats.

According to the report, the majority of these devices sold will be via the retail channel, although significant numbers will also occur through HVAC contractor, Home Security/Automation, and Utility channels.

Assuming a mix of devices priced between $150-$250, with cost declining slightly year over year, and relatively linear growth in the overall market, this could mean a $1 billion to $1.3 billion opportunity in the United States alone.  No small figure.

Making a Case

Parks’ breakdown of the multiple sales channels show that retail is by far the fastest-growing channel, followed by HVAC. The chart also shows that utilities and home security/automation channels are expected to experience less upfront growth in the near-term.

This distinction between channels is helpful, but quite possibly one of the most interesting aspects of the smart thermostat market has been the overlapping of sales channels that has occurred recently.  Through Bring Your Own Thermostat (or BYOT) programs, utilities are looking at how they can decrease overall program costs, mitigate risk, and increase consumer choice by networking consumers’ pre-purchased devices into their demand response and energy efficiency programs.

Similarly, in Spring 2015, Commonwealth Edison (ComEd) incentivized Comcast Xfinity Home customers to sign up for Comcast’s Summer Energy Management Program, managed by EcoFactor (ComEd also incentivized Nest owners to sign up for that company’s Rush Hour Rewards demand response program).

As vendors in this market show no signs of decreasing their level of creativity in marketing these devices to consumers across different geographies and demographics, the market will continue to evolve.  In terms of overall home energy management, smart thermostats are just the beginning.  The recently published Navigant Research Leaderboard Report: Smart Thermostats provides a comprehensive overview of leading vendors, recent market activity, and both current and forward-looking market trends.
