Home energy auditing is a focused inspection service in the building industry that seeks to identify and motivate investments in energy efficiency improvements. In many cases, the audit process does not translate into actions by homeowners (Palmer 2013). Barriers to action by homeowners include a lack of information, financial concerns, and a lack of trust between auditors and homeowners (2009 CEQ Report). The goal of this research is to characterize the trust relationships among home audit processes, the accumulation of trust, and the intention to take action based on auditor interaction with homeowners. The relationships between trust attributes and implementation of energy improvements are presented as performance metrics to measure value exchange during the audit process. The designs of a classification framework and the questionnaire instrument to evaluate trust-value exchange are also presented. The instruments are used for multiple audit delivery processes to characterize the relationships between the trust-value exchange during audits and the intention to invest in home improvement projects. To assess this exchange, typical value-adding processes that take place during audits are characterized based on observation of audits under various circumstances. The contributions of this study to the enhancement of business development and building characterization processes are discussed.
