Work done

Creation of the idea, the concept of operation and the computer application of a tool that, by means of a fast data entry (it should not exceed 10 minutes) and a simple interpretation of results (it should be understandable by people without experience in the subject), allows the home user to obtain a diagnosis of their own case compared to a standard or reference situation.

This analysis of household energy and water consumption should also provide practical information on how to reduce them through three levels of intensity of user intervention: changes in their use patterns, light modification of the facilities and reforms of the construction systems, air conditioning, lighting, toilets, etc. The project included the research on the statistical data used by the tool both to determine the energy and water consumption of the reference model and to estimate the ones of the house to be analysed, as well as their interpretation in order to carry out a comparative evaluation. the writing of the improvement tips that are offered along with the diagnosis.



The tool offers, quickly and easily, an approximate evaluation of the efficiency with which the main resources (energy and water) are consumed in each home. It can be used by anyone from the Internet and, in addition to the information that appears in the following screens, automatically performs a comparative diagnosis and lists some improvement actions that the user receives in his e-mail in the form of a pdf document.
