The Proforma assesses overall energy performance by aggregating estimates of the energy consumed across the embodied, operational, and transport dimensions -- over time, then subtracting the potential for renewable energy production resulting in a measure of the net present energy value for the neighborhood.

Operational energy :

Heating ; Cooling ; Lighting ; OtherUses

Transport energy :

Transportation energy per household

Embodied energy :

Residential Building ; Infrastructure

Renewable energy :

PV ; Wind

Fuel Sources

production potential of the neighborhood from solar (hot water and electricity) and wind sources.
Operational energy

Consumed in private residential units and in the use and maintenance of common facilities and spaces of the neighborhood. In all of the neighborhoods studied, the Proforma predicts operational energy to be the largest contributor to overall energy use, paralleling what was observed empirically.
Transportation energy

Consumed by those who live, work, and visit the site to undertake their daily activities of living.
Embodied energy

Consumed in the building and site construction (earth moving) of the neighborhood.
Renewable energy

production potential of the neighborhood from solar (hot water and electricity) and wind sources.
