Intelligent Heating, Ventilation, and Air Conditioning Controls for Low-income Households: A Low-cost, Connected Device That Understands Consumer Preferences and Performs Adaptive Optimization

California's pursuit of energy system decarbonization encompasses multifaceted strategies, notably efficient building electrification and the implementation of time-of-use rates. A pivotal component in achieving these goals involves the integration of smart thermostats, offering a potential solution for optimizing heating and cooling loads in buildings while harmonizing energy reduction with occupant comfort. Regrettably, disadvantaged communities face barriers, lacking access and financial means to embrace these transformative technologies that could enhance their energy efficiency. 

In order to advance California's overarching decarbonization objectives while upholding principles of equity and social justice, it is imperative to bridge this accessibility gap. Despite advancements in low-cost sensors and wireless communications, making smart home technologies more broadly available, their adoption within lower-income communities has historically been sluggish. This project is expressly designed to confront the technical and market challenges inhibiting the widespread adoption of smart thermostats among residents in California's disadvantaged communities. 

The initiative involves a comprehensive approach, encompassing the design, development, and deployment of a smart thermostat meticulously tailored to meet the unique needs of disadvantaged communities. By doing so, the project aspires to not only enhance energy management but also alleviate associated costs for this population. This report explains the intricacies of the project's processes and highlights its outcomes, offering valuable insights and recommendations for the heating and cooling industry. These recommendations aim to facilitate the broader transition to time-of-use rates and building electrification in California, fostering a more inclusive and sustainable energy landscape.
