DESIGNING BUILDINGS FOR DISASSEMBLY KONSTATINOS KOUKOULOPOUSLOS
The following is an excerpt from Konstantinos Koukoulopoulos’ master thesis: ”Designing Buildings for Disassembly - Challenges, Guidelines and Environmental Performances”, DTU. Supervised by lektor Morten Birkved and lektor Lotte Bjerregaard Jensen. “4 Results 4.1 Rules of Thumb In this chapter, the "Rules of Thumb (RoT)" regarding implementation of DfD in buildings is presented. In the next sub-chapters the general guidelines, a range of guidelines for common structural frames and installations, and the existing assessment tools regard-
Similar to Crowther (2001), the contribution of a guideline to the EoL scenarios was assessed to be: - “Highly relevant “. When the guideline is mandatory (“Don’t use hazardous materials” for “Material recycling”) or makes critical difference for a specific EoL scenario (“Manageable weight and
