theoretical study some concepts such as : the total construction cost , delivery , future economical savings will not be analysed . However , some constructive aspects are presented to show how the standardisation and simplification process could lead to achieve a lower price production . Moreover , it is noticed that there is more potential living area in the simplified models than in the original one , which correspond with the necessity of more space .
The following table also make prognosis of each model ’ s annual energy cost , which was based on the 2013 AMPLA ’ s3 electrical cost of £ 0.10 for each kWh for dwellings that consume more than 220 kWh and £ 0.09 for the ones who consume less that 220 according to the ANEEL4 . Furthermore , the authors highlighted the options that seem to be as the best options according to the comparative analysis between the design options generated during the methodology ( Table 14 ).

In this study case DB3 and DB4 are showed as the most feasible models to fulfil the methodology goals in a long-term affordability . To clarify their differences the following resume table can be developed in order to observe the saving that can be done compared to the original project or against the other design option ( Table 15 ).
