Building Green had a discussion of Zero Energy definitions
in a recent Environmental Building News article:

Getting to Zero: The Frontier of Low-Energy Buildings
Environmental Building News October 2005
http://www.buildinggreen.com/articles/


NREL has also recently published a series of performance
metrics definitions:

Is there a clear "official" definition of Net Zero, for homes, and/or
separately for commercial or other larger buildings?  The term is being
applied to some larger projects than just homes.  For taller buildings, the
roof area gets to be too small to meet the energy needs of the building
just with PV, and wind is problematic in urban settings.  Can bio-diesel,
wood pellets, or other "renewable" fuels from off-site used in on-site
generation, and/or combined heat and power, be considered part of a "net
zero" project?
