Life Cycle Assessments and Environmental Product Declarations – Green Labels for the Home

Product Life CycleJust about everyone who shops for groceries looks at the nutritional label on the product.  I believe that we have been conditional to do so and it’s probably a good thing.  We should want to know what ingredients are going into the prepared foods that we eat. We can control the amounts of fat, sugar, salt and preservatives that go into the food we eat but only if we can easily get the data.

In a similar way, the building industry is moving toward tools such as Life Cycle Assessments (LCA) and Environmental Product Declarations (EPD) to test and validate the “greenness” of their products. These are some of the best tools available to help consumers make the right choices when selecting products to purchase.  Would you think to ask your contactor for the Life Cycle Assessment for the siding you are putting on your home?  If you care about the space you create and the world you live in then maybe you should.

Manufacturers work with third-party certifiers to test and quantify the environmental impact of all the materials used to make the product.  Companies that are undertaking these assessments are ’walking the green talk’ because it is a long process to secure LCA’s and EPD’s.

Beware of GreenwashingAs the demand in the marketplace for environmentally friendly products increased, manufacturers created a form of spin in which green marketing was used to promote the perception that an organization’s products, aims and/or policies were environmentally friendly.  This “greenwashing” is still happening today.

That is why consumers need to be aware of the “nutrition” labels for products they are using to build or renovate their homes. The life and efficiency of your home is important.

Life Cycle Assessment Tells the True Green Vinyl Siding Story

In a previous blog, Who Says Vinyl Siding Can’t Be Green, I started to discuss the move to manufacturing vinyl siding products with recycled content making it a more sustainable product.  This began a quest to dispel the misconceptions about vinyl siding and the fact that vinyl is a more sustainable cladding solution than brick, stucco or even cedar.

Vinyl siding has long been viewed by some as a product assumed to not be environmentally friendly.  Well, I am here to tell you that following a very long and tedious process of conducting what is called a Life Cycle Assessment (LCA) on CertainTeed’s vinyl siding products that vinyl siding is GREEN!  Based on all the elements that go into the LCA such as raw materials, transportation, production, and installation vinyl siding clearly leads the way in sustainability. CertainTeed’s vinyl siding LCA has been accepted by the National Institute of Standards and Technology (NIST) through the Building for Economic and Environmental Sustainability (BEES) program which is a leader in the credentialing of LCAs.

The LCA provides full public transparency and ensures that manufactures are not engaging in green washing.

The LCA is an analytical tool used to quantify and interpret the flows to-and-from the environment over the entire life cycle of a product, process or service.  It is also referred to as cradle-to-grave analysis. The goal of the LCA is to compare the full range of environmental effects assignable to products and services in order to improve processes, support policy and provide a sound basis for informed decisions.

The term ‘life cycle’ refers to the notion that a fair, holistic assessment requires the assessment of raw material production, manufacture, distribution, use and disposal including all intervening transportation steps necessary or caused by the product’s existence.

Our first step was to create LCA’s for all of our vinyl siding lines.  In all cases, our vinyl siding outperforms alternative cladding products such as brick, stucco, Dryvit Outsulation and even cedar in all of the environmental impact calculations identified in the BEES methodology.

CertainTeed is committed to product stewardship and the LCA, as well as the entire process to complete the LCA because it provides us with information to continue to improve processes to reduce their environmental impact.

CertainTeed will continue the LCA process on all of our siding product lines as a firm commitment to our mission in sustainability.
