“Beyond Zero Net Energy” with Marc Rosenbaum
November 14, 2017 @ 5:30 pm - 8:30 pm
Join Us at Two Roads Brewing Company
The next step “Beyond Zero Net Energy” is pushing to see how much energy used on site can be supplied by the PV system. In suntempered superinsulated housing, with PV system sized to zero out the annual consumption, only about 1/4 of the PV energy is used as it is generated. On-site battery storage makes it possible to drive this fraction up significantly. We’ll look at daily and seasonal residential energy use data from low energy homes, and how that compares to PV generation. Using an simulation tool that uses hourly inputs for energy use and PV generation, we’ll examine the effects of varying battery and PV array sizing, as well as load variation, on the degree of renewable self-consumption that can be achieved. We’ll draw some insights from all this and the implications for how we think about design.
- Upon completion, participants will be able to describe both daily and seasonal patterns of residential energy use in low load houses.
- Upon completion, participants will be able to draw and describe a basic PV plus battery storage system conceptual one line.
- Upon completion, participants will be able to describe how battery storage changes self-consumption fraction both daily and seasonally.
- Upon completion, participants will be able to describe how adding battery storage to PV systems on low load houses changes how we think about designing those houses.

Marc Rosenbaum, P.E. is a long-time student of making great buildings. He uses an integrated systems design approach to help people create buildings and communities connected to the natural world, supporting both personal and planetary health. Much of his recent work has been Zero Net Energy Buildings, Deep Energy Retrofits and Passive Houses. His work has been recognized nationally by ASHRAE, AIA, EEBA, and NESEA, but they didn’t see all the mistakes along the way.
