Process of assessment
The assessment comprises three stages:
. Stage 1 <Assessment purposes>: to determine the weighting factors.
. Stage 2 <Individual assessment>: to assess all relevant individual
performance indicators.
. Stage 3 <Overall assessment>: to compute the overall performance based
on the weighting scheme determined in stage 1 and the value of individual
performance indicators determined in stage 2.
This is illustrated in the following figure.
The five performance indicators are influenced by the five building features. Their interactions are considered in the Matrix Tool.
Each of the performance indicators has a value ranging from 0 to 5, with 5 indicating the best and 0 indicating the worst. Once these individual performance indicators are assessed against the relevant building features, the overall performance is computed as below:
where:
are the value of individual performance indicators:
Built Environment, Responsiveness, Functionality, Economic and Suitability
respectively.
are respectively the weighting factors for
individual performance indicators .
And:
The value of IQ specifies the "intelligence" of a building under the "Matool".
The maximum value of IQ is 125. The rating of the intelligent building is
accordingly specified as follows:
. Bad: <50
. Good: 50 ~80
. Very Good: 80 ~100
. Excellent: 100~125
