Abstract

'Smart' thermostats regulate the home temperature by self-programming using heuristic evaluation of user habits and occupancy. Within the Phased Deep Retrofit (PDR) Project in Florida, a total of 26 NEST thermostats and two Lyric thermostats were installed in participating homes. Unlike previous evaluations, a full year of sub-metered hourly temperature and heating and cooling system operation data was available prior to the install of the smart thermostat allowing detailed evaluation of temperature-related changes. Overall measured heating and cooling energy savings averaged 9.5%.
