Even though the software we developed is quite good and complete, there are something that can be done in order to have a more sophisticated tool:

• Since embodied energy is at a research level, in the future an advanced database can be integrated in the program

• Also in the future figures about the transportation and the disposal part of the embodied energy may be available, so these can also be integrated

• Links with other M&T programs will be welcome

• Probably a better user interface can be developed, preferably in a computer language form (i.e. C++)

• Further research should be done with the indices we have developed, in order to become credible.
