What makes Building Materials “Green”?

            What exactly makes one building material green and another not? A selection process of course! A material to be considered green has to fall under the following criteria: resource efficiency, indoor air quality, energy efficiency, water conservation, and affordability. A product is considered to be green based on the impact that the product will have on the environment throughout its life.
            To assess the products before they are deemed to be green there is a product selection process, which involves research, evaluation, and selection. This process starts with the finding of different manufacturer’s products and information on them. This step also usually involves researching environmental and other issues that may arise in relation to the product.
 In the evaluation part of the process the product is tested and the manufacturer’s information is compared with the information that is found by the testing agency. A life cycle assessment (LCA) is also done, and looks at the product from the production process (and where the materials come from) to the expenses that will accumulate from the utilization of the product.
            The final step is the selection process. This part utilizes the scores that are established during the evaluation part of the selection process. The higher the score, the more environmentally friendly attributes it will have. This can also be done on a project-to-project basis so the right products will be utilized for the project.

  1. I never knew the criteria that building materials had to fall under to be considered green. I am always looking for greener options to replace certain items in my home. I want to do everything I can to be as environmentally friendly as I can.
