Hi,
There is two methods of transport for the Cement I use for concrete in my project; It is coming by water to the port from an approximate distance of 2100 Km and then shipped by truck for 148 km to the concrete manufacture then to the project for another 25 km.
Can I Count the Cement as regional material for this case?
Your feedback is appreciated.

Hi Rezkar,
Which rating system are you using?
In the meantime you can use the LEED Reference Guide for Green Building Design and Construction with Global ACPs (Alternative Compliance Path) located here: http://www.usgbc.org/resources/leed-reference-guide-green-building-desig...
There is a formula which you can use to calculate the regional distance based on the mode of transport. Hope this helps.

Rezkar – The MRc5 Global Alternative Compliance Path that Amit cited has officially been incorporated into LEED-2009.
An Addendum issued in July 2012 added compliance OPTION 2. As noted in the “Birds-Eye View” at the top of this webpage, “This new option allows you to do a prorated calculation based on the lower relative impact of shipping materials by rail or water.” This option allows you to divide the distance shipped by sea by 15. Therefore, since
(2100km/15) + 148km + 25km = 313km < 800km (500mi),
you should be able to treat the cement as “regional” if it was shipped by sea.

Thanks for your Feedback. I am using LEED NC 2009, CAGBC. Is this calculation acceptable under Canadian LEED too?

I believe that LEED Canada has always had a distance calculation of its own that is similar but a bit different in the specifics—I would use that.

Rezkar - Just remember that, if you use the options that Amit & I sent, distances shipped by sea calculate differently than those by inland waterway. The calculation shown above assumes sea travel. If your cement travels 2100km via rivers & canals, rather than by sea, you may be out of luck.
Just curious…Does CAGBC treat the Great Lakes as seas or inland waterways?
