[Bldg-sim] carbon footprinting of building materials

Take a look at GEMIS: http://www.oeko.de/service/gemis/en/index.htm

 

I used it not too long ago and was almost overwhelmed by what's in it.
It takes a little time to learn, but it seems like a very powerful
resource.  From the website:

 

The GEMIS database offers information on: 

*	fossil fuels (hard coal, lignite, natural gas, oil), renewables,
nuclear, biomass (residuals, and wood from short-rotation forestry,
miscanthus, rape oil etc) and hydrogen (including fuel composition, and
upstream data)
*	processes for electricity and heat (various powerplants,
cogenerators, fuel cells, etc.)
*	materials: raw and base materials, and especially those for
construction, and auxiliaries (including upstream processes)
*	transports: airplanes, bicycles, buses, cars, pipelines, ships,
trains, trucks (for diesel, gasoline, electricity, and biofuels).

GEMIS includes the total life-cycle in its calculation of impacts - i.e.
fuel delivery, materials used for construction, waste treatment, and
transports/auxiliaries.

The GEMIS database covers for each process 

*	efficiency, power, capacity factor, lifetime 
*	direct air pollutants (SO2, NOx, halogens, particulates, CO,
NMVOC)
*	greenhouse-gas emissions (CO2, CH4, N2O, SF6, all other Kioto
gases)
*	solid wastes (ashes, overburden, FGD residuals, process wastes)
*	liquid pollutants (AOX, BOD5, COD, N, P, inorganic salts)
*	land use.

Dear all,

>From all those out there who are basing their building material and
specifications decisions on Lifecycle Analysis/carbon footprinting, I'm
curious to know what tools you have been using and the challenges you
have faced.

I'm also interested in references of consultants who can aid in such an
effort.

Thanks,
