researcher Sheila Conejos, several architects, developers and building stakeholders were asked about their opinion on the social implications of adaptive reuse of existing buildings. It was observed that most respondents thought that adaptive reuse is important to the society because old buildings are critical to the image and history of a society. They agreed that historical buildings add to the aesthetics of a townscape and should be preserved and reused. Environmental considerations Buildings consume high amounts of energy during their life-cycle. New construction requires new building materials and other resources which possess high embodied energy (throughout their extraction, manufacture, transportation, packaging and assembly phases). Additionally, they also cause high environmental damage such as global warming, eutrophication, ocean acidification, ozone layer depletion, carbon emission which in turn harms human health and quality of life. From this standpoint, there are several environmental benefits associated with building recycling or adaptive reuse. Water efficiency Water is an important component in building construction. Water is needed at every stage of a building's life, from building material extraction to manufacture, on-site construction processes such as concrete mixing, cleaning, etc., operational phase in the form of plumbing for human use and landscaping and fire safety, and at the end of its life for recycling building materials or disposing them. Selecting adaptive reuse over brand new construction can help relieve the planet of such water loads. Energy conservation Just as water is needed in every stage of a building's life, so is energy. This energy is conventionally obtained from non-renewable sources and causes high carbon emission. Minimizing fossil fuel depletion and carbon emission can be huge contributing factors to reducing global warming and mitigating climate change. Choosing to demolish an existing built asset and then constructing a brand-new building in its place can lead to high energy requirement for the demolition, building material waste management, new material procurement, construction and operation. On the other hand, sustainably retrofitting an existing built asset only requires a fraction of this energy. It is important to keep in mind that many of the old building may not have the best of operational energy use efficiency. Therefore, to achieve a successful adaptive reuse project, the designers must keep the building's energy use intensity at utmost importance. Materials and resources Building materials are generally procured from the Earth's strata or are end products of processed natural components. These resources are limited. Irresponsible extraction of
