Carbon Dioxide Intensity Factors
A Method of Evaluating the Upstream Global Warming Impact of Long-Life Building Materials Richard MacMath, Center for Maximum Potential Building Systems.

 
The Kyoto Protocol and the U. S. delegation’s agreement (in principle) to a 7% reduction of total GHG emissions (a 30% reduction over projected 2015 emissions) focused the nation’s attention on climate change and global warming. The most significant Greenhouse Gas emitted in the U.S. is carbon dioxide (CO2) - 82-84% of all U.S. emissions. The industrial sector accounts for one-third of national CO2 emissions with manufacturing activities accounting for the largest share of the sector. The top-ranked manufacturing industry in terms of the total impact of CO2 emissions is the building industry. The upstream phase of processing and manufacturing building materials and products causes enormous off-site impacts prior to the building's use. Minimizing the upstream impacts of building materials must be a part of a global and national GHG reduction strategy.

To derive a CO2 intensity factor for long-life building materials, the following methodology was used:
· Upstream CO2 emissions data related to the building industry are collected and interpreted.
· A life cycle analysis of each long-life building material to be examined is performed. The method relies on an accurate portrayal of two industrial processes occurring during the upstream life cycle stages of each material: the embodied energy used (i.e., fossil fuel consumption) and the physical and/or chemical processes utilized to transform materials. 
· The upstream CO2 emissions per unit weight of a material or product are calculated.
· The carbon sink potential of the material, if any, is identified.
· A comparison of CO2 upstream emissions to the carbon content of a material yields a net CO2 impact.
· Comparing the net CO2 impact to the end use weight of a material yields a useful ratio for evaluating global warming impact – a carbon dioxide intensity factor.
· Materials that are net upstream CO2 sources and net upstream CO2 sinks are identified.


Subsequent to assigning a carbon dioxide intensity factor to various materials, the net CO2 impact of building products and components made up of a number of different materials can be assessed. For example, the net CO2 impact of small building material assemblies - office furniture and partitions – can be estimated.

In addition, the net CO2 impact of a hypothetical small building can be assessed as an example of the methodology applied at a building scale. Finally, the tabulation of the CO2 balance potential of the schematic design of a new 250,000 sq. ft. office/academic building can be summarized and compared with a baseline building.

Program and directions:
6:00 - 7:00 Tour the CMPBS and get an orientation to the Advanced Green Building Demonstration Building 
7:00 Program begins Carbon Dioxide Intensity Factors
From downtown: Take MLK Blvd. heading east towards 183 
From the north or south: Take U.S. 183 (Ed Bluestein Blvd.) to MLK (exit and head east on MLK/FM 969) 
Go 1 mile east from U.S. 183/MLK intersection. The CMPBS will be on your left at the top of the hill immediately before the intersection of FM 3177 (Decker Lane) and FM 969. Look for 8604 on the mailbox. {If you go to the traffic light at FM 3177 (Decker Lane), you have gone too far!}  Park in front of the farmhouse by FM 969. Walk down the gravel driveway that heads west and turn right following the path to the Advanced Green Building Demonstration Building.

FOR SALE - Green Real Estate


You’ve done the environmentally sensitive thing, built a "green" house, but now you want to sell it.  Bill Christensen, Sustainable Sources, has developed a great new service.  Essentially, it's searchable classified ads for green-built properties.  You can list your own - just fill in an online form, and if you have a picture to add, just upload it or email it to them.  And the best thing about it is that any properties listed between now and September 1, 1999 are absolutely free.  So spread the word!

When they do start charging, it'll be a one-time fee.  Your listing can run until it sells - all you'll have to do is log in once a month and confirm that it's still on the market.  For full details, check it out at http://www.greenbuilder.com/realestate/.

We’re looking for a few good folks …



… to support and guide the SBC! Since the SBC’s inception 7 years ago, a very dedicated, small group of volunteers has been providing SBC members and guests with an information-filled newsletter, monthly speakers and programs on current sustainable topics, and an annual membership directory. To ease the load of these volunteers, the SBC is need of some fun loving, self-starters to help keep the SBC vibrant, current, and informative. Some of the potential areas for getting involved include:

* Facilities and equipment 
– room setup, equipment maintenance
* Speakers and programs
 – topics, ideas, coordinating, arranging
* Education and outreach   – establish connections with other groups to share and exchange
* Newsletter distribution 
– fold, stamp, and mail monthly newsletter
* Mailing list – data entry, organizing, updating
* Site visits   – ideas, organizing, coordinating
* Student liaison  – UT, ACC students willing to help promote the SBC on their campuses and increase student membership.
* Other  – If you have suggestions, ideas, etc. that you are willing to devote your time and effort to see come to fruition. 

If you’re interested in assisting in these or other areas, please call Shellie Reott at 444-0980 or send e-mail to earthly@io.com. We know you’re out there, so please step forward.

Cob Survey



Interest in developing knowledge and skills using "cob" (moist soil, sand and straw) to build walls, benches, ovens and dwellings is being expressed from many places to those of us who have been involved with cob. Thus, we are considering offering a sampling of cob building materials and techniques over a week-end this fall.  The survey is designed to determine the extent of local interest. Call Yvonne Hansen at 447-0459 geminideas@greenbuilder.com.

To respond via phone, state item number (1 through 4) then your answer, "Yes" or "No".  If you want to be on the mailing list, also give your name, phone
number, email address and or USPS address. Please respond by August 15. Thanks.

1. I am interested, but know nothing about cob.Y/N
2. I have some knowledge/experience with cob, and want more. Y/N
3. I would attend a week-end sampling of cob (evaluating and mixing soils; foundations and wall building; door/window bucks; finishing (possibly plasters, roofing, Y/N
4. I am willing to pay a modest fee for such a week-end ($100-$150). Y/N

Whole Life Expo October 8



SBC has been offered a most excellent gift: the opportunity to bring attention to the importance of improving architectural performance in the US to achieve the principles embodied in green building materials and process, permaculture, and related fields.  SBC's mission has been education, and WLE offers an opportunity to achieve this.

We are offered a "furnished" booth that will give us exposure to perhaps as many as 20,000 people. SBC will have a descriptive paragraph in the program guide which is anticipated to reach 500,00 people!  We will be mentioned in daily newspapers, radio and tv.  A presenter or our choice will have time to speak on a topic we believe is significant. This is a most excellent opportunity to tell others what is possible in terms of healthy living in non-toxic buildings in vibrant neighborhoods, to show what one person, a family, a group, can achieve by making a few informed decisions.

This is what is needed: a Planning Project team of 4-5 of you to design and execute our booth; decide on major themes and content (i.e., literature, graphic displays, etc.); volunteers to sign up for a few hours each at our booth; who knows what more?  The PP team, and you, will decide.  The SBC can contribute additional substance  to the international reputation Austin has for green building. Join us!  Call Yvonne Hansen, 447-0459 or geminideas@greenbuilder.com
