Embodied CO2 accouting in Revit

Here's my project: Using Revit to measure the embodied energy, in terms of CO2, of a building. Although my firm usually analyzes a building's operational energy, we haven't yet studied the embodied energy of a building's materials.

The Revit prep work--creating some shared parameters for materials, organizing schedules and material takeoffs--is straight forward. But what source do we use for our material data? I realize that measuring energy/carbon flows is a nebulous, complex thing, which means this can only be a rough estimate. So far, I've found these sites:

Sourcemap http://www.sourcemap.org/
EC LCA Tools http://lca.jrc.ec.europa.eu/lcainfoh...tCategories.vm
BFRL’s BEES Software http://www.bfrl.nist.gov/oae/software/bees/bees.html
Pharos Project (in development) http://www.pharosproject.net/
BLDG 2.0 (in development) http://www.case-inc.com/content/bldg...gy-performance

Has anyone done research on this? Any advice is appreciated!

Do you think Autodesk would include this sort of material information in future releases?

Would this from Bath university be of use? Different for transport energy etc depending on where in the world you are of course...

This may be too late for you, but we have produced a system for calculating the embodied carbon of construction, civils and refurbishment projects.

The application sits on top of our carbon data platform which includes the entire Bath university ICE database as mentioned by Elrond.
