Abstract

In this research, considering the decisions of retrofitting strategies for energy conservation, the planners undertake the interviews to examine. Eight cases are selected to be studied according to two common types of buildings and five common retrofitting strategies of building openings in Taiwan. Seven determining factors are clarified in research results: (1) capability of improving indoor thermal environment, (2) capability of resolving existing opening problem, (3) affordability of retrofitting cost, (4) constructability, (5) legality, (6) building appearance design and (7) affecting scope during the retrofit. Moreover, different combinations and importance of determining factors order affect decisions of retrofitting strategy as well.
