1. DESIGN FOR DECONSTRUCTION AND DISASSEMBLYINTRODUCTIONIn the building industry, sustainability is a measure of how much damage a structure causes to the environment. A sustainable building always requires certain procedures to minimize and limit damage to its environment. Nowadays, every architect has something to say on this topic, but their ideas mainly focus on the energy aspect and innovative materials. One of the best ways to assess the sustainability of a building is to use the Life Cycle Assessment (LCA) model. An LCA model studies the environmental impacts of each stage of a building's life cycle (Crowther, 2001, p. 3). This model can also be used to determine in which sector buildings have the most negative impact. As shown in Figure 2, electricity consumption and waste generation have the greatest impact (Bayer, Gamble, Gentry, & Joshi, 2010, p. 43). It can therefore be concluded that by minimizing construction waste and energy consumption, this industry can be more sustainable. FIGURE 2 CONTRIBUTIONS OF ENVIRONMENTAL IMPACT To get a better perspective on this issue, it is important to analyze the approach of other industries. Compared to other industries, the construction sector offers products on a larger scale. However, they pay special attention to the recycling and reuse of barley. With the constant growth of the world's population, the demand for natural materials is increasing more and more. Over the next 50 years, material use will increase by 300%. The construction sector is 50% responsible. In addition, 40% of waste production also comes from this sector (Durmisevic, 2009, p. 14). Most construction waste is generated by demolition and renovation interventions. To minimize this waste production, an alter...... middle of paper ......asidharan & Chani, 2011, pp. 35-36).TABLE 2 ADVANTAGES OF DFDD• Reduction of construction waste• Possibility of reuse of a component in a new structure• Efficient use of natural resources• Possibility of transporting the entire building• Reduce the consumption of energy and CO2 emissions• Extend the life of a building by providing the possibility of renovation and modification.• Increase the value of the building and its components when the structure is required for a short period. • Make the structure more flexible. • Dismantling is faster than demolition, so labor costs are reduced. STRATEGIES AND PRINCIPLES In the previous sections, different aspects of DFDD have been analyzed. This section is dedicated to various possible strategies and principles that can be used in a DFDD-based design. what can we do? Michael Pulaski answered this question very explicitly
