6: Sustainability and Environmental Analysis a. Carbon Footprint In the past, the choice of materials when creating a building was not an issue. Now, the Green house gasses emitted from the buildings is 38% of our total GHG (20% Residential, 18% Commercial). Due to the rise in GHG over the last decade, we have now been looking at different materials and building options with a much lower carbon footprint impact. Some of the future projects are based entirely on the material and building choices which are the most environmentally friendly.
b. Embodied Energy Embodied energy is the key aspect which decides whether the product contributes or mitigates global warming “Embodied Energy is the sum of all the energy required to produce any goods or services, considered as if that energy was incorporated or 'embodied' in the product itself.” (En.wikipedia.org, 2011) This concept is used to tell us how effective an energy producing or energy saving product is.
c. Recyclability Recyclability is a concept based on the choice of materials used to construct a design, and the way these materials were used. It is the process of extracting useful materials from a constructed design and reusing them. “Construction waste recycling is the separation and recycling of recoverable waste materials generated during construction and remodeling.” (Constructionwaste.sustainablesources.com, 2013) The recyclability of a building is a more sustainable form than demolishing the building as it leaves room for re-use of these materials instead of extracting raw materials from the environment, thus leaving a smaller carbon footprint behind.
7: Economical Implication of Design The materials used in the MSLE buidlings include: -Structural Concrete -Stainless Steel: Relatively strong compared to Aluminium and other steels. It is affordable (considered quite expensive compared to non-stainless steel) and it has a good lifespan. It won’t rust easily and is strong against heat.
