This report describes the designed methodology for the activities plan to be developed at the Living Labs. All these activities will be consecutively executed. First of all, the validation framework is defined by specifying the Living Lab sites, the validation scenarios, collecting end-user requirements and analyzing the current state and performance of the buildings with an ex-ante evaluation. Following, the first intervention actions will take place in the roll-out phase, with the installation of the required equipment, the calibration of the models and the realization of a first trial in order to evaluate, optimize and re-calibrate the models and develop a second improved trial phase. After this, the results will be validated, and an analysis of the impact and cost-benefit will be done.
