"Smart Shelter Check List"

(an intemediate level program form for natural building)

 

The following is a check list indicating several concepts used in sutainable building. It is intended to be used as a source for ideas which may be applicable to your building project and at the same time deter the overuse of our resources in your efforts to provide safe, less-toxic, affordable, owner buildable structures which work efficiently for many years in this climate (western Colorado). It is by no means complete in terms of listing all concepts used in sustainable building. If you know of more please contact us to have yours included here. Through community we grow to a better world.

PRINCIPLES FOR SUSTAINABLE BUILDING

* Prostainability- look for systems that give back more than they consume

* Disposal costs- take into account how, where and at what cost the

the structure will be disposed of after the end of it's life.

*Life cycle costing- in making system and materials choices as well as

building size(space efficiency), compare costs and benifits for

the entire life of the unit, not just its initial cost.

*Retirement Investment- consider life impact for retirement living if you

use renewable on site energy sources, reduced home size

(don't forget property taxes) heating costs/ insulation systems,

etc.....money is hard to invest in something that will return

the savings that a good house will.

*Embodied Energy- consider before you buy where the product came from, how much petroleum it took to transport it, the energy it

took to produce it.

 

a few things to think about:

 

* More energy goes into the construction of a house than it will use

in its lifetime.

*500 manmade chemicals are present in our bodies that did not

exist before 1920. (Theo Colburn)

*80,000 new chemicals have been registered in the U.S.

in the last 50 years. Only 1,000 have been tested for their effect

on the human nervous system. Only 100 are regulated for use.

250,000 violations of those regulations are recorded annually.(EPA)

*Germany has not allowed the use of formaldehyde in building

materials for 15 years.

*The total human labor invested in the average American home is

1.7 years.

*Colorado population has grown 297% since 1954. (Colorado

Population Coalition).

*Despite recycling, the rate of forest tree cutting has increased in

recent years. (Yale School of Forestry)

*The average American, in a lifetime, consumes 540 tons of construction

materials. (Population Reference Bureau)

*30% of U.S. citizens contain sufficient pollutants to create BRI-

Building Related Illness. (World Health Organization)

*Over 80% of the average American's life is spent indoors.

*Buildings in America consume 30% of our energy output, 60% of

our electricity and financial resources and 26% of our landfill

volume. (Rocky Mountain Institute)

*Enough straw is burned each year in the U.S. to build 4 million

2,000 sq. ft. strawbale houses.(USDA)

*10% of the old growth forests of the Pacific Northwest are still

standing. (ZPG Magazine)

* 70% of Americans rate the U.S. environmental problems as serious.

50% say those problems are now affecting their lives.( Gallup Poll)

* Coloradoans now rate problems with our environment as their #2 concern

(second only to growth)....three priorities higher than crime

(Norwest Bank Public Policy Research Program, l997)

* American environmental consciousesness is now at an all-time high.

Corporate, industrial and governmental response to that is at an all-time low.
