What are the benefits of Designing to Disassemble?

Designing a building to later disassemble it may sound like more work and hassle than it's worth, but with resources worldwide diminishing we all need to plan for the future and make the best use of what we have available now. Aside from the obvious benefits to our environments, costs to repair parts of a building would be decreased. Instead of having to perform extensive repairs and replace large sections, a small panel or portion might just need to be changed. The needs of buildings often change sometimes requiring involved renovations to fit the new occupancy's needs. With designing to disassemble techniques a contractor could implement the new design by unbolting and changing the current panels and components of the building to rearrange and suit the new use.
