anything like in Austin, it will mean that about 10% of homes sold will undergo an energy upgrade; perhaps a conservative assumption is that, in any given year, 1% of rental units leased will undergo an energy upgrade. This equals 15,000 homes receiving energy efficiency retrofits each year.
Conclusions The model proposed in this paper presents a new, improved way to implement disclosure of residential energy performance and a rating approach that offers a comprehensive and more easily understood picture of residential energy performance. The access to more complete information provided by a well-designed strategy for residential energy labeling can transform the way stakeholders seek residential energy efficiency. In the proposed model, building owners are provided with clear information on their building’s performance, through a platform that enables them to understand retrofit needs, more easily connect to retrofit opportunities, and share information with third-party organizations and applications. For prospective tenants and homeowners, this model provides easily accessible and comparable information on the energy performance of a potential new home, enabling more informed decisions and the use of energy efficiency as a decision factor. As a result, tenants and homebuyers collectively can create a market signal for more efficient homes. Cities, states, and utilities all benefit from this approach, with up-todate, detailed information available on the performance and needs of housing stock. The result is a wellinformed housing market, enabled by transparency to seek out and catalyze residential energy efficiency.
