Abstract:
In the past decade, significant investments have been made to advance residential energy auditing methods to enable reduced energy consumption in the residential sector. Previous research has identified four barriers that make homeowners less likely to implement energy improvements: (1) lack of information, (2) financial concerns, (3) lack of available workforce to implement improvements, and (4) conflicts of interest between auditors and homeowners. The goal of this research is to develop methods to measure value-trust exchange in home energy audits in a quantitative way and assess the impacts of trust attributes on homeowner’s intention to take action. Additionally, this research seeks to improve the efficiency and effectiveness of home energy audits. Literature review and industry practice are used to identify types of value-trust exchanges in the home energy audit process. These value attributes are used to examine value-adding interactions leading to information delivery and trust relationships between homeowners and auditors. Models are developed to evaluate 90-minute home audits and evaluate the types and efficiency of value-trust exchanges that take place during in-home energy audits. Forty-eight surveys and thirty in-house audit recordings were collected to develop statistical models of trust attributes, constraints on energy improvements and homeowners’ personal characteristics. The contributions to this research are (1) the systematic identification of value-trust exchanges which take place during home energy audits, (2) a systematic measurement of value-trust exchange in home energy audits, and (3) identification of practical activities related to critical trust attributes that may be utilized to improve the accumulation of trust during audit process planning and design.
