Adaptive reuse is the reuse (or conversion) of an existing building for a purpose other than that for which it was originally built or designed. The adaptive reuse of buildings can be a viable alternative to new construction in terms of costs, aesthetics, and sustainability among other benefits.
== Definition == Adaptive reuse is defined as the aesthetic process that adapts buildings for new uses while retaining their historic features. Using an adaptive reuse model can prolong a building's life, from cradle-to-grave, by retaining all or most of the building system, including the structure, the shell and even the interior materials. This type of revitalization is not restricted to buildings of historic significance and can be a strategy adopted in the case of obsolete buildings.
== Advantages of adaptive reuse == Typically categorised under economic, social, cultural and historical, and environmental benefits. The most significant benefits of adaptive reuse of existing buildings include increased economic opportunities, urban regeneration, preserved cultural and historical heritage values, reduced landfill demolition waste, increased energy efficiency, extended building usefulness, and cost-effectiveness, enhanced property value, improved life quality, reduced carbon emissions, and lesser energy consumption. Some urban planners see adaptive reuse as an effective way of reducing urban sprawl and environmental impact. According to Yung and Chan, "adaptive reuse is a new kind of maintainable rebirth of city, as it covers the building's lifetime and evades destruction waste, encourages recycles of the embodied dynamism and also delivers substantial social and economic profits to the world". Revitalizing the existing built fabric by finding a new use or purpose for obsolete buildings can be a wonderful resource to a community by "keeping neighborhoods occupied and vital". The reuse of older vacant buildings for other purposes forms a very important aspect of any urban regeneration scheme. Adopting the adaptive reuse approach for the redevelopment of older vacant buildings provides added benefits to the regeneration of an urban area in a sustainable way, through transforming these buildings into usable and accessible units. The adaptive reuse strategy would also enable the local authority and owners of older vacant buildings in urban areas to minimize their economic, social and environmental costs, in a quest for a continued urban expansion and development. Built heritage conservation through adaptive reuse could therefore be used to promote sustainable historical and cultural development of urban areas. Parameters to prioritise historical buildings for adaptive reuse and the characterisation of adaptive reuse stakeholders are also noted.
Architectural beauty and cultural heritage: According to Zaitzevsky and Bunnell, old buildings physically link us to our past and become a part of our cultural heritage; they should be preserved because of their "architectural beauty" and the "character and scale they add to the built environment." A majority of historical buildings provide physical links and the progression of cultural evidence to the past. Cost savings on building material: Adaptive reuse involves the refurbishment of existing building members, which tends to be a relatively labor-intensive process and relies less on purchasing and installing many new building materials. Cost savings on demolition: Demolition costs may range from 5% to 10% of the total cost of new construction. This expense is often overlooked by many building owners. Some urban areas have strict building safety regulations and may not allow the usage of a swinging ball and other more efficient demolition techniques. Under these circumstances or a desire to reuse and recycle materials from the existing structure, buildings must be demolished piece by piece, which might be more expensive and often is more time-consuming. Saves time: The total time required to renovate an existing building is generally less than the time required to construct a comparable amount of floor space in an entirely new building. A major advantage of renovating an existing building is that a refurbished portion of the building becomes suitable for occupancy before completion of the whole project. This provides as a notable advantage for those worried about cash inflow or space shortages while the rest of the project undergoes construction. Decreased public and social costs: Urbanization and urban sprawl cause several harms to our planet and the society. Lack of adaptive reuse of existing built assets can lead to dislocation of residents, economic decline and disruption of community life, eventually leading to abandoned and obsolete neighborhoods. Buildings and the development around them soon become the heart of a community upon which people's life depends. Regular maintenance and reuse of existing structures can help communities avoid the trauma caused by dilapidation, abandonment and clearance. This can help reduce the dislocation of residents, economic decline and disruption of community life, eventually leading to abandoned and obsolete neighborhoods. Old buildings are often found in fully developed neighborhoods where public amenities like sewers, water lines, roads, etc. have already been established. Adaptive reuse means that governments and municipalities have less infrastructure to build and maintain. In a survey conducted by researcher Sheila Conejos, several architects, developers and building stakeholders were asked about their opinion on the social implications of adaptive reuse of existing buildings. 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 benefits: Modern building systems have high life-cycle costs and operational energy costs associated with them whereas traditional masonry and stone buildings are more climate-responsive. A significant environmental benefit of reusing built assets is the retention of the original buildings "embodied energy" in the building materials. The adaptive reuse of existing buildings can be adopted to facilitate climate change mitigation and is generally considered the most sustainable approach to developing and using a building.
