ABSTRACT
This chapter presents details of the design approach. It needs to reduce energy demand by improving building energy efficiency. The needs to consider the efficiency of various systems and various renewable energy options that are suitable and feasible for the building we are designing. Methods that are used to investigate building performance in response to much larger timescales of monthly changing conditions or on the basis of one calculation per year are not dynamic simulation models (DSMs) and cannot be used as design tools. There are many well-established numerical methods for dealing with this kind of problem of multidimensional optimisation, and one of the most efficient of these methods is based on evolutionary computation, namely on genetic algorithms. The need to run building simulation with different values of design variables and to find optimum building performance from a combination of number of alternative values of parameters has created a new range of tools, or new functionality within existing simulation tools.
