== Challenges == Typically categorised under building regulatory requirements and governance, financial, management, and complexities and uncertainties challenges. The most significant challenges of adaptive reuse of existing buildings include structural integrity issues, compliance with building code regulations, government anti-adaptive reuse policies, lack of awareness, high maintenance cost, uncertainties surrounding existing building information, lack of incentives, and lack of decision-making tools and stakeholder participation.
== Predicting successful reuse == According to Chusid's "urban ore" concept, existing buildings that are fast approaching dilapidation or disuse are a "mine of raw materials for new projects". Shen and Langston built upon Chusid's idea and said that "an even more effective solution than raw material recovery is adaptive reuse". They studied that "a huge focus on economic factors alone has led to the destruction of buildings well short of their physical lives". Shen and Langston developed an integrated model for the assessment of adaptive reuse potential (ARP model) in 2008 by comparing case studies of one urban and one non-urban setting. The basis of this model lies in that "opportunity rises and falls within the confines of a negative exponential decay function linked to a building's physical life expectancy". According to their study, a building reaches its maximum potential for adaptive reuse at a point when the building's age and its useful life merge or meet. At this point, the building's adaptive reuse potential is either an upward curve or a downward curve which can determine whether the potential is high, medium or low. The adaptive reuse potential calculator establishes a "predicted useful life" of a building by considering a series of physical, economic, functional, technological, social, legal and political characteristics. These characteristics are used to derive an "annual obsolescence rate" and "environmental obsolescence". These outcomes are necessary to determine an optimum point at which adaptive reuse intervention should occur. An algorithm based on a standard decay (negative exponential) curve produces an index of reuse potential (known as the ARP score) and is expressed as a percentage. This decay curve in buildings can be used to establish an ARP score, which is expressed in percentage. Cities can rank their existing buildings as per their adaptive reuse potential and this data can be used by government authorities at any point in time. An adaptive reuse score of 50% or above is considered high. A low ARP score is anything below 20%. Anything between that range is considered moderate. Shen and Langston devised this concept of ARP as "rising from zero to its maximum score at the point of its useful life, and then falling back to zero as it approaches physical life". AdaptSTAR is a 2013 model to facilitate adaptive reuse projects and has also been shown to be a good predictor of a successful project along with the ARP model. A 2023 literature review identified some key factors for whether an adaptive reuse project would be a success. Architectural factors include whether the project minimizes intervention in the character of the structure, that new elements are compatible with the building without trying to pretend to be old, whether the interventions can be easily modified or reversed, maintain aesthetics such as the beauty of aging characteristics of a building, embraces creativity in the use of space while remaining functional. Structural factors emphasize the importance of extending the lifespan of the building among other practical factors. Cultural factors focus on the ability of the building to contribute to a sense of place and community pride, attracting the interest of the community in participating in its new phase of life, while improving the quality of life of its users. Economic indicators of success include whether land values have increased as a result of the project, shortening the construction period, saving on material costs, and helping develop local craftsmen and restorers, any boosts for tourism, and whether the tangible and intangible benefits outweigh the costs. In addition to environmental and energy considerations, there are authenticity and historic factors, including being able to tell the story of important events, maintain the congruity of a historic streetscape, and identifying and prioritizing the preservation of the features with the most heritage value.
== Methodology == Adaptive reuse projects are, in many ways, different from conventional new construction projects and must be planned and managed differently.
=== Building condition assessment === Before starting an adaptive reuse project and even considering refurbishment, it is important that the condition of the existing building is thoroughly assessed. A condition assessment primarily inspects a building's structural integrity, roofing, masonry, plaster, wood-work, tiling and the mechanical, electrical and plumbing systems. The in-depth inspection of buildings can be expensive. Nevertheless, building condition assessment is critical to the success of an adaptive reuse project and must not be avoided at any cost because this expense is insignificant relative to the injury or loss of life that a building failure might cause. One logical reason, as explained by the American Society of Civil Engineers, is that even a very well constructed building could undergo serious deterioration and eventually failure, if proper maintenance is not performed in the operational phase of the building. The direct inspection of the structural system is required to a certain degree which is decided by the judgement of an experienced civil engineer. Sometimes, built assets cannot be considered suitable for adaptive reuse, simply because of the constraints of their built form or the condition that they are in. Former jails and mid-1900s low-rise apartments that have low floor area ratios (FAR) and which may be in some of the cities' prime locations have tended to be seen as less profitable for adaptive reuse. According to Bullen and Love, the buildings of the 1960s and 1970s in Perth were badly constructed, used ineffective thermal insulation materials and details and have low suitability for adaptive reuse, while the built form of the 1980s was deemed to be engineered to specifications and could accommodate an adaptive reuse model.
