This webinar is a follow-up to our December 6, 2022, presentation – watch video from the first webinar on this project.

Bayview Tower multi-family apartments offers low-income housing to the elderly and disabled in a 100-unit affordable senior apartment building operated by the Seattle Housing Authority in Belltown.

With an eye towards environmental stewardship, the Bonneville Power Administration (BPA) and Ecotope, Inc. worked together on a pilot with support from Sky Centrics and Seattle City Light (among others) to undertake the retrofit pilot project: replacing the electric resistance water heaters with an ultra-efficient CO2 commercial heat pump water heating system. The new system, which operates at an annual COP between 2.4 and 3.2, has reduced the building’s domestic hot water energy use by nearly 60%. Assembled as a skid in a factory, delivered onsite by truck, and lifted onto the building’s roof via a crane, the installation was achieved in a single afternoon, with minimal disruption for residents.

This webinar is the second for the Bayview Towers series. It will include the load shift analysis of winter data, a few lessons learned items, future looking BPA efforts on CHPWH pilots and programs, and more! Come in ready to engage our presenters and panelists and ask questions.

Learn and ask questions about the story behind this project, the strategies used to have various systems communicate, load shifting, shedding, and other strategies for efficiency, best practices, and forward-looking trends!
