- •
An alternative performance indicator for evaluating Net Zero Energy Buildings is presented.
- •
The overall renewable energy fraction (OREF) accounts for on-site and off-site renewable energy.
- •
OREF is as an indicator of the independency from fossil fuels energy carriers.
- •
Three approaches for crediting exported energy are discussed: no credit, payback and avoided burden.
- •
The more consistent approach is not crediting the exported energy.
