In the long term, there is evidence that accessible and affordable housing is crucial to the health, wealth and sustainability of a community (Enterprise, 2014). In Arizona, the ramifications of regressive tax policies and discriminatory zoning and credit practices have led to what has been termed an “affordable housing crisis” where Arizona is ranked the third worst in the nation for affordable housing (NLIHC, 2020). The research grapples with the policies and history of housing in Arizona, with specific focus on the policies regarding lending, tax and zoning. Access to opportunities and resources (food, health, etc.) is significantly related to housing, thus exploring what kind of homes are available to whom and where those homes are located is critical to understanding the disparate barriers inadequate housing imposes and the impact housing has. To understand this we must understand the role of the state in ensuring an equitable housing market, and the intimacies of what is already happening at local level. The goal is to explore sustainable solutions that can bridge the affordable housing gap and provide protections for residents in the volatile housing market.
One way of reducing cooling and heating energy in residential buildings is by allowing the centralized HVAC unit to supply conditioned air to only occupied portions of the house by applying smart HVAC zoning. According to the United States Energy Information Administration [3], the percentage of houses equipped with centralized HVAC units is over 70%, which makes this thesis applicable to the majority of houses in the United States. This thesis proposes to implement HVAC zoning in a smart way to eliminate all human errors, such as leaving the AC unit on all day, which turns out to be causing a serious amount of energy to be wasted.
The total amount of energy that could be saved by implementing the concepts presented in this thesis in all single-family houses in the U.S. is estimated to be about 156 billion kWh annually. This amount of energy reduction is proportional to the electricity bills and the amount of dollars paid annually on energy that is technically being wasted.
