The main purpose is the design and development of an integral system for the energy inspection and energy evaluation for buildings with high energy-saving potential, which will make possible the proposal of effective rehabilitation actions towards the reduction of the CO2 footprint and the conversion of those buildings into zero-consumption buildings. First of all, all the typologies of buildings have been studied to choose which one is the ideal model. A multidisciplinary approach has been applied to deal with this task, including the design of an indoor unit mounted on a trolley and a UAV drone unit for the complete, geometric and thermographic, measurement of the building’s envelope. All processed data have been compiled in Building Information Models (BIM) containing also all the information required for the energy evaluation of the building. These models were made with all the data georeferenced so they could be automatically incorporated into the energy analysis software. Several of this energy analysis software were used to evaluate the model and the results have been compared, focusing on the complexity and the percentage deviation of results. A methodology for evaluating the energy generated by buildings has been developed, and it also includes the creation and evaluation of innovative building solutions that would lead us to reduce energy consumption. These solutions have been gathered in a manual for use in several similar buildings.
