1. ZERO NET ENERGY
@ SFUSD

2. THE CASE FOR ZNE
The planet needs bold action.
Our buildings are not getting more efficient quickly enough. Energy usage has
been mainly dictated by weather, not sustainability efforts.
Jurisdictions all over the world are stepping up.
San Francisco, CA, US, Germany, Europe, UN
Other districts have similar plans.
Boulder Valley has a goal to reach ZNE by 2050. San Diego is right behind.
Schools across the country are going ZNE. There are
examples in Seattle, New York, LA, Arizona, Texas, and even Kentucky.

27. DISTRICT STRATEGY
NEW SCHOOLS
 ZNE Required
MODERNIZATION
 ZNE-Ready
RENEWABLES
 On-Site Solar

28. WHY STOP THERE?
Effective Immediately
- New buildings will be ZNE
- No new gas heating systems
BY 2020, SFUSD will
- Fuel its buses with renewable diesel
- Reduce its energy & water usage by 30%
BY 2030
- All vehicles owned by the District will be emissions-free
- The District will reduce its natural gas and water usage by 50%
By 2040
The District will no longer burn fossil fuels for heat or transportation.
