Buildings today need to be designed while keeping the future in mind. Changing needs of society, scarcity of material and environmental impact of producing and demolishing buildings are significant considerations for the designers throughout the world.

Buildings today need to be perceived as impermanent and as material banks for the future. By adopting the outlook of impermanence, a building can be designed to reduce waste and use materials efficiently at all stages (construction, operation and end of life) as it addresses possible changes in circumstances. An impermanent outlook to architecture compels us to think of resource minimization, optimization and management.

Obsolescence is inevitable, but its effects can be softened by designing buildings that are flexible and that consider the end of life. Such buildings are not only beneficial to the environment and future generations but also the purse of the present user.

The dissertation states that sustainability lies in considering the embodied energy and operational energy of the building and its components. The building uses lesser resources throughout its lifespan by designing an efficient structure, climate efficient design, flexible planning to address change, detachable and reusable components, and reducing maintenance by separating different functional spaces and components of the building. After reduce, a building should be designed with the objectives of reuse and recycle in mind. Here material selection and joining become of paramount importance. The design focuses on using and detailing materials that can easily be reused or recycled at the end of the building's or components life to ensure a reduction in waste and optimization of resources for future generations. For this aspect vast research of various materials and their life cycle impact was studied and applied.
