How long will this study last and how much of my time will be required?

This study will take place over two years, beginning in summer 2021. During the first year, we will monitor your home and passively collect data from the smart thermostat and sensors. During the second year of the study, we will intervene with your heating and cooling system to test new approaches for adjusting the timing and frequency of your home’s energy use to maximize overall grid energy efficiency. Throughout the study, we will periodically ask you to complete short questionnaires to document any major changes that may affect your thermal comfort or the energy demand of your home. Also, you will periodically be prompted to respond to 30-second thermal comfort surveys on your study-provided Fitbit in clusters (e.g., two to three times a day, on various days).
