as CFD or other simulation software. If accurate results are required, each
evaluation can be time consuming, and thus the complete computational process
becomes extremely unattractive.
• GAINN is one of the techniques to deal with this problem by approximating the
system under study by an ANN whose results are then used within the GA.
3 Conclusion
In face of a large set of choices for retrofitting a building, the main issue is to
identify those that prove to be the most effective in the long term. When choosing
among a variety of proposed measures, the DM (the building expert) has to rec-
oncile environmental, energy, financial, legal regulation, and social factors to
reach the best possible compromise solution to satisfy the final occupant needs.
Therefore, MCDA and MOP models are essential tools to assist the DM in
rationalizing the comparison between non-dominated solutions and assess the
trade-offs at stake between those distinct evaluations aspects.
Thus, there is a need for further development of decision-aid systems based on
MCDA and MOP to support building experts in the application of their expertise
and assist less-experienced decision makers (DM), while taking into account the
continuous development of technological advances in energy-efficient solutions.
