Adaptive reuse of inner-city buildings: methods for minimising waste and stimulating the economy

There is a growing number of aged and obsolete buildings all over the world due to the rapid restructure of the economy. Even though ageing buildings experience physical, functional, technological and economic obsolescence, demolition can be a premature decision. The aim of this research is to identify methods of adaptive reuse of buildings to minimise waste generation and stimulate the economy using the Central Business District (CBD) of Adelaide as a case study. The results showed that adaptive reuse of buildings provides substantial amount of social, economic and environmental benefits. Key factors affecting the decision of reusing buildings include: financial, technical, functional, cultural/historical and legal. Cost analysis showed that conversion and refurbishment costs can be increased due to technical risks. Similarly, it is necessary to consider the functional and cultural values in adaptive reuse of buildings. However, there are some restrictions in the Australian National Construction Code and other legislation in relation to adaptive reuse of existing buildings especially in fire and safety requirements, earthquake resistance, hazardous substances, disability access and environmental protection. Despite benefits of providing flexibility in using them in existing buildings, there are practical impediments associated with compliance with these legislation and standards.
