The latest in a series of Lessons Learned: Peer Exchange Call “greatest hits” summarizes top marketing and outreach takeaways from the Energy Department’s Better Buildings Residential Network members during spring 2015 Peer Exchange Calls:
- Effective marketing of multifamily upgrades depends on whether the decision maker is a tenant or building owner. Tenants are more concerned with issues, such as reduced noise, enhanced comfort, and lower energy bills. Owners are more concerned with enhanced marketability of a unit (e.g., the aesthetics of installing new window treatments).
- Stand-alone outreach events, such as workshops, can have difficulty attracting people to a venue just for that event. Instead, focus on leveraging pre-existing events and community groups to educate people.

Successful residential energy efficiency programs use data collection, transfer, and storage systems to effectively implement activities and track program metrics. While systems based on simple spreadsheets can be easy to develop, such systems might not be suitable as program scale increases. Programs across the country have found immense value from investing the time and resources required to create an information technology (IT) system to regularly monitor progress and automate time-intensive manual processes. From customized data management systems to mobile-friendly systems that allow data entry and access from the field, programs have found ways to use data more efficiently and drive upgrades and program progress.
