Net Zero Energy‐ Most common use
Zero Net Energy‐ Used by DOE and State of CA‐ Grammatically correct
Zero Energy‐ More appealing to Owners?‐ The end‐goal?
Source or Site Energy?
PHnw 2017 Cowhorn Tasting Room
Offsetting Source Energy with Onsite Renewables
Site: ‐ Simpler metric‐ More applicable for Homes?
Source: ‐ More inclusive:
‐ Imported: gas/steam/biomass‐ Exported: charged EVs
‐ Very difficult to achieve
Cost:‐ Compromise between Site + Source‐ Used by ASHRAE 90.1
Time based (CA):‐ Minimizing peak demands and keeps “dirtiest” plants off grid

How Passive House Fits In
PHnw 2017 Cowhorn Tasting Room
‐ Maximizes reduction in peak loads‐ Reduces overall energy use dramatically‐ Additionally, PHI and PHIUS incentivize renewable
energy
PHI: Primary Energy Renewable (PER) factor‐ Accounts for different uses + fuels at different times of
source energy‐ Includes on and off‐site renewables‐
PHIUS: Source Energy Offset ‐ Includes Campus Certification‐ Includes on‐site renewables and battery storage
