The proposed method was used to optimize a single room
model, considering the building envelope parameters as decision
variables and the building energy demands as the cost functions.
However, it is expected to apply the method to a more complex
building system, aiming not only to bring down the whole building
energy use, but also to optimize other important terms of the
building performance such as the thermal comfort, the environmental
impacts, the embodied energy, and the investment costs.
Therefore, more design parameters may be considered if the goal
is extended to cover these objectives in future studies. In addition,
robust multi-attributes decision-making methods, such as LINMAP,
TOPSIS, and Fuzzy approaches may be used to investigate
the performance of the methods
