Advanced homebuilding technologies are not used as frequently as the more standard construction technologies described in previous chapters, which involve the use of masonry, wood and concrete. However, as with other innovations, it is hoped that over time these new technologies will gain greater acceptance. For the purposes of the World Encyclopedia of Housing, advanced technologies include seismic isolation and passive energy dissipation devices. To date, the WHE database contains three reports describing advanced technology applications: two describe China's baseline isolation systems (WHE Report 9) and Kyrgyzstan (WHE Report 76), and the third report describes the use of a system of seismic protection developed in the former Soviet Union, known as "unlinking reserve elements" (WHE Report 77, Russian Federation). The first application of advanced technologies in housing construction dates back to the 1970s. For example, the sliding belt insulation system was developed in Russia around 1975, with its first application in Kyrgyzstan in 1982. The decoupling reserve elements (DRE) were developed in Russia in 1970 and were first applied in 1972 The first code dealing with this type of construction was issued in 1981. In China, the widespread use of basic insulation for housing has only been used since 1990, with the first code addressing this technology published in 2000.
