In the past the evaluation system is rather simple which implies a simply solution when the dilapidated house need to be regenerated. An intact marking system need to be introduced instead of the simply classified the architecture with qualities. For instance, in the ORPHCC, preservation are only for traditional courtyard houses which marked as heritage. What about the rest dilapidated houses which are not listed as the heritage? They are not architecture in good condition for sure, but are they of no value at all? When we give the assessment for the inner city, here at least 5 dimensions should be examined to answer this question(Fig. 17):
(1) Historical: this means the architectures with great importance and authentic as historical heritage.
(2) Culture value: this represents a important aspect of culture and the spaces that support it.
(3) Scientific and technique value: this means that architecture could represent a build technology of a certain time period, or material, structure of the time.
(4) Usage value: this represents the possibility to transformation on the function into others
(5) Environmental value: this is the condition on the energy consumption point of view.
