Sustainability In Building Industry

In the building industry, sustainability is a measure to determine the harm of a structure to the environment. A sustainable building always takes certain procedures to minimize and limit its damage to its surrounding. Nowadays every architect has something to say over this topic but their ideas are mainly focused on energy aspect and innovative materials.
One of the best ways to evaluate sustainability of a building is by using life cycle assessment model (LCA).A LCA model investigates the environmental impacts of each stage, in the life cycle of a building(Crowther, 2001, p. 3). This model can also be used to determine in which sector, buildings have the most negative impact. As it shown in Figure 2, electricity consumption and waste output have the greatest impact(Bayer, Gamble, Gentry, & Joshi, 2010, p. 43). Therefore it can be concluded that by minimizing the building waste and energy consumption, this industry can be more sustainable.

To get a better perspective of this issue, it is important to analyze the approach of other industries. In comparison to other industries, building sector has products with bigger scale. However, they give barley attention to recycling and reuse.
With the ever growing of world population, the demand for natural material is increasing more and more. Over the next 50 years, the material usage will increase with a 300% factor. The building sector is responsible for 50% of it. In addition, 40% of waste production is also from this sector (Durmisevic, 2009, p. 14). Most of the building waste is generated by demolition and renovation interventions. To minimize this waste production, an alter...

• Reduction of construction waste
• Possibility of reuse of a component in new structure
• Efficient use of natural resources
• Possibility of transportation of the whole building
• Reduce energy consumption and CO2 emission
• Extending the life span of a building by giving a possibility for renovation and modification.
• Increase the value of the building and its components when the structure is required for a short time.
• Make the structure more flexible.
• Disassembly is faster than demolition therefore, lower labor cost.
In the previous sections, different aspects of DFDD were analyzed. This section is dedicated to various possible strategies and principles that can be used in a DFDD based design. what can be done? Michael Pulaski answered this question in very explicit way
