The concept of life cycle analysis evolved since the concept was initially considered in the 1970s and 1980s, [3] when life cycle studies focused on the quantifying the energy and raw resources used by a building, and the load on the sewerage and sanitation systems imposed by waste generated in the building, during the operational life of the structure.
The concept stage, in fact, is one of the major steps in a project life cycle, as it has the largest impact on cost and performance. [27] In designing environmentally optimal buildings, the objective is to minimize the total environmental impact associated with all life-cycle stages of the building project.
This is quantified through life cycle analysis that measures the impact of a material over its lifetime, which stretches into the "D phase" that includes end-of-life waste after the building is demolished. [14] [15] Waste transportation adds costs to both construction and building maintenance. Designing refurbishments that reduce waste, and ...
The "building life cycle" is an approach to design that considers environmental impacts such as pollution and energy consumption over the life of the building. This theory evolved into the idea of cradle-to-cradle design, which adds the notion that at the end of a building's life, it should be disposed of without environment impact. The Triple ...
Since 1994, much progress to sustainable construction has been made all over the world. According to a 2015 Green Building Economic Impact Study released by U.S. Green Building Council (USGBC), the green building industry contributes more than $134.3 billion in labor income to working Americans. The study also found that green construction's ...
An illustration of the allocation of avoided burden and recycling benefits across life cycles. Avoided burden (also known as the 0:100 method or end-of-life method) is an allocation approach used in life-cycle assessment (LCA) to assess the environmental impacts of recycled and reused materials, components, products, or buildings.
Life cycle inventory analysis is followed by a life cycle impact assessment (LCIA). This phase of LCA is aimed at evaluating the potential environmental and human health impacts resulting from the elementary flows determined in the LCI. The ISO 14040 and 14044 standards require the following mandatory steps for completing an LCIA: [52] [53] [54]
This includes material selection, recycling, reuse, renewability, toxicity, and durability. Section 505 requires a minimum of 55 percent of the material used in a project to be either used, recycled, recyclable, bio-based, or indigenous, unless a whole building life cycle analysis is conducted in accordance with Section 303.
