The ultimate outcome of this project is the reinforcement of the robust prediction of energy use in buildings, allowing the correct estimation of short and long term measurements as well as the determination of strategies and technologies to be used. The main objectives are: develop a new methodology for energy use analysis, which would make it possible to study the effects of the main influencing factors demonstrate how these data can be used to provide meaningful indicators of energy performance of buildings (e.g. energy consumption typically encountered in different types of buildings) develop a methodology for predicting the performance of energy saving policies and technologies that include the influence of a number of factors develop a methodology and technology for long-term monitoring of energy use in buildings.
