While the DB4 option seems to be the most adequate project to be erected. After the choice is
made, some other interchangeable attachments should be chosen by the user to adequate the
project to some immediate needs. This stage finish when the project is delivered to the user and
erected on site, in that moment the project DB4 shift its name to DC. It is also observed that the
area is amplified without increasing the dwelling footprint.

Post occupancy modifications
This stage cannot be tested in this study due to its intuitive nature and the user’s mandatory participation. (Fig. 25).

Conclusions
The methodology presented in this study, not only tackle the home energy qualities, it also contributes to the modularisation and standardisation of the home components in order to achieve
lower costs. It is also presented as a practical way to assess the users and designer to choose and
design the most energy efficient option. This method follows different stages giving specific role
to the designer and user in order to streamline the process. The EST plays an important role during
the energy “efficiency upgrade” stage helping the designer to generate different design options.
Then, the comparison made in the “select the accurate choice” stage is fundamental to realise
the efficiency and potential of this method. Finally, the author concludes that the methodology
