User perceptions of a range-based thermostat

Abstract

In a vicious cycle, the rise of global temperatures increases demand for cooler indoor temperatures, while increased use of air conditioning leads to warmer outdoor temperatures. Most modern indoor-climate control systems aim to maintain thermal neutrality i.e., a near-constant indoor temperature, over entire spaces, if not also over time. This consumes significant resources while causing thermal discomfort for some indoor occupants. In an online study, this work explored user perceptions towards dynamic indoor temperatures, which can lead to significant resource conservation. The study included two conditions, early versus late exposure to a range-based thermostat, to assess its user acceptance, in the context of study participants’ 1) summer temperatures, 2) general temperature preferences and habits, 3) temperature-unit preference, and 4) extra-thermal factors. Due to local COVID-19 restrictions on in-person research, initial results will report on users’ behavioral intention.
