A conceptual model for evaluation
The key features of the Design Quality Indicator (DQI) satisfy the required criteria for developing a conceptual model. It suggests that the DQI is suitable for being adapted for the design of a new tool that can be used for the post-occupancy evaluation of small-scale public transportable buildings. The evaluation indicators should be reasonable and appropriate, which means that they present the key features of transportable buildings, and they are concerned with the building's functional performance, but no other performance, including energy costs and temperature measurement. The function-finance-timescale-aesthetics (FFTA) tool assists a transportable building's management team in defining and checking the evolution of functional performance quality at the post-occupancy evaluation stage. The FFTA questionnaire is a coherent, straightforward, non-technical set of statements that collect opinions from all stakeholders by looking at the function, finance, timescale and aesthetics of small-scale public transportable buildings. The FFTA conceptual tool has been developed for the post-occupancy evaluation of small-scale public-use transportable buildings.
