This publication summarizes lessons learned from Peer Exchange Calls about how energy efficiency programs and partners can leverage timing to engage homeowners.

The multifamily sector can be hard to reach when it comes to energy efficiency programs. Besides being diverse and complex, the sector presents a unique set of challenges to efficiency investments. The result is that multifamily customers are often underserved by energy efficiency programs. Drawing on data requests and interviews with program administrators, this report summarizes the challenges to program participation and identifies best practices that programs can use to reach and retain large numbers of multifamily participants.

The lack of documented value of retrofit measures is a barrier to many homeowners doing upgrades - as most appraisals do not include energy improvements in their comparables, and the homeÕs future sale can prevent the homeowner from earning a return on their investment via lower energy costs. Once the industry develops a process for valuing the energy improvements, it can unlock the significant potential for retrofit work through market pricing signals (energy efficient homes are worth more) and enhanced access to capital for those purchasing a more efficient home (energy efficient homes improve borrowersÕ cashflow because they cost less to operate).

This paper explores ways in which program administrators are using social norms to spur behavior change and, as a result, curb energy use. In recent years, home energy reports (HER) programs have applied the concept of social norms to the energy efficiency context. These feedback programs inform customers of how their energy consumption compares to their neighbors' and provide other information about their usage, with the goal of enticing customers to change their energy use behavior to improve their relative neighborhood ranking.
