50 best sustainable building materials
In recent years there has been a growing concern for the sustainability and more environmentally friendly focus in all sectors especially building construction. Architects such as ourselves are always trying to put forward alternative sustainable building solutions, not because it's a trend, but because there is a responsibility we have as designers to ensure that clients who are concerned about such green matters are aware of the alternatives out there. It brings us pride that we can help clients reach their green and sustainability goals.
In order to determine our top 50 sustainable building materials, let’s get to the core of our concern and really understand what the word sustainability is and what factors constitute something as ‘sustainable’.
What makes a building material sustainable?
A quick google search will tell us that the definition of sustainability is:
“The avoidance of the depletion of natural resources in order to maintain an ecological balance.”
But there are several factors that make a sustainable building material. We will use these metrics as a method of scoring our materials to determine which is best for sustainability for building construction for the location of the site/
For a building material to be truly sustainable it must meet the following criteria:
a) Vernacular
If a building material is close by, it’s a common sense option to use it. Vernacular architecture is a proven method of sustainability, in both environmental, economic and social aspects.
b) Resource Efficient
The efficient use of resources throughout the product’s life cycle, from extraction throughout manufacture, use and disposal is important to take into account when making this assessment. A cradle to cradle approach is important to consider to ensure that there is little to no waste and the resource is maximised.
c) Renewable
Can this product be replaced easily or regrown quickly to account for the rate of harvest or excavation? This is important for sustainability to ensure the material can replenish naturally over time or manage sustainably.
d) Socially Responsible
Fair trade and community well-being is an important human right factor that should be included within the manufacture and production of the material, to ensure the safety of workers and its consumers. Not to mention the by-product waste of the material must not adversely affect the environment. This is essential to the sustainability philosophy.
e) Economic Viability
Full lifecycle costs and including maintenance expenses should be assessed to ensure that this material is even financially viable in the long term. It’s no use if a material is sustainable if the client will have to keep replacing it. Sustainable building materials need to make sense financially, as well as environmentally.
