Figure 4: Energy efficiency upgrading stage diagram.
When the prototype DnB fulfils the energy requirements it will be named DnBx. This new prototype can be improved so it can continue flowing through the energy efficiency loop creating new eligible options DnB( x + 1). Therefore, x is a number given to identify the different options generated by the loop process. E. g. If a design prototype called“ D2B” its implemented to the energy efficiency loop and after some modifications it achieve the energy standards, it turns its name into“ D2B1” and continue improving it energy efficiency. After each modification the design progress should be recorded and named differently( D2B2, D2B3 …) for further affordability calculations. This process can be repeated as many times as wanted.
Selecting the accurate choice
This stage is characterised by the evaluation of the options resulted from the energy efficiency upgrading stage. Then, the different options are ranked in a comparative table to assess the user
