Abstract
This thesis studies the environmental symbiosis technologies, which are applied to refurbishment and improvement of small-to-medium size old urban building stocks. The study was examined through the renewal project of a 36-year-old laboratory building of Kanto-Gakuin University. Part one explains the design concepts and the integration of various symbiosis technologies in this project. The unit devices of the symbiosis technologies are strategically placed on the building surface to realize architectural integration.
