Adaptive reuse refers to the process of reusing an existing building for a purpose other than which it was originally built or designed for. It is also known as recycling and conversion. Adaptive reuse is an effective strategy for optimising the operational and commercial performance of built assets. Adaptive reuse of buildings can be an attractive alternative to new construction in terms of sustainability and a circular economy. It has prevented thousands of buildings’ demolition and has allowed them to become critical components of urban regeneration. Not every old building can qualify for adaptive reuse. Architects, developers, builders and entrepreneurs who wish to become involved in rejuvenating and reconstructing a building must first make sure that the finished product will serve the need of the market, that it will be completely useful for its new purpose, and that it will be competitively priced.The AECROS Re-Use-A Block system is engineered especially for temporary structures. Thanks to our re-useable modular units MBU-R (aka REUSABLE BLOCKS), low cost reconfigurable buildings will become the future standard for industrial construction worldwide. The MBU is non differentiated on the block exchange, but in the field can either be designated MBU-P (Permanent), or MBU-R (Reusable) for reconfigurable structures. Due to its unique engineering features the MBU-R can accommodate a far greater insulative value for use in extreme climates. The MBU-R has a much higher “strength to weight ratio” for building without concrete. The MBU-R is lighter for transport and installation in remote locations. It might also be noted that these units will be particularly suitable for the movie industry and also temporary public venues. Presently the movie industry has a relatively poor track record regarding wasted materials. It’s time for a positive change.
