Vectren’s Nest thermostat study finds ‘significant’ savings

Vectren designed, funded and conducted the program that started in fall 2013. The company replaced manual thermostats in 600 homes, installing Nest thermostats in 300 homes and standard, programmable thermostats in 300 homes, and hired a third-party to evaluate the program.

The Nest customers saved more than twice as much heating energy in the winter compared to the standard programmable thermostat customers, a “statistically significant” difference, officials said.

Vectren’s rebate program for 2015 now includes a $100 rebate toward a Wi-Fi enabled programmable thermostat, such as those offered by Nest. For more information, visit vectren.com/saveenergy.
