eTEACHER concept consists of encouraging and enabling energy behaviour change of building users by means of continuous interventions displayed through a set of empower tools to drive informed decisions in order to save energy and optimise indoor environment quality. These empower tools are a set of ICT solutions that ensures friendly connection in between end-users and building systems, implement continuous behavioral change interventions and provide tailored advice. The tools can be classified into BACS (Building Automation and Control Systems) add-ons and end-user friendly solutions. The BACS add-ons (What-if-Analysis, data processing and universal BACS/monitoring system interface) are responsible for collecting information from the building, pre-processing data to focus on relevant metrics related to the use of energy and indoor environmental quality, exploring potential energy conservation measures (ECMs) and post-processing data in order to present it in a way that can have more impact on users behavior.The user friendly solutions are energy efficiency and comfort advisor apps for end-users devices (mobiles, smartTV, smartwatch, dashboarding). These apps show the ECMs identified by BACS-addons and integrates ICT-based behavioural change techniques such as gamification (games, challenges, bonus system, energy literacy, energy visibility, etc.) according to different roles (visitors, facility managers, owner, etc.) as building users and according to cultural and demographic indicators. An important feature of the advisor apps is that they collect feedback from end-users regarding comfort and satisfaction that are used to customise ECMs and engagement techniques. The project is demonstrated in 12 real buildings located h 3 different climate conditions. The pilots located in Spain are 2 residential buildings, 2 schools and 2 health care centres. The pilots located in UK are an office building and a school. The Romania pilots are 4 residential buildings.

NewTREND seeks to improve the energy efficiency of the existing European building stock and to improve the current renovation rate by developing a new participatory integrated design methodology targeted to the energy retrofit of buildings and neighbourhoods, establishing energy performance as a key component of refurbishments. The methodology will foster collaboration among stakeholders in the value chain, engaging occupants and building users and supporting all the refurbishment phases through the whole life cycle of the renovation. The methodology will be supported by an online platform to ease collaborative design, which will play the role of exchanging information and facilitating dialogue between the different stakeholders involved in the retrofit process. It will store all the information useful to the design of the retrofit intervention in a cloud based interoperable data exchange server, i.e. the District Information Model server, which has the ability to and export multiple file formats thanks to semantic web technologies. A Data Manager tool will be developed to guide the designers in the data collection phase, which might be a complex task for retrofit projects where information and drawings are scattered or even not available. The NewTREND platform will be a tool for collaborative design allowing evaluation of different design options at both building and district level through dynamic simulations via a Simulation & Design Hub. Design options, including district schemes and shared renewables will be presented to the design team, together with available financing schemes and applicable business models, in a library which will build on lessons from past and ongoing R&D projects. The NewTREND methodology and tools will be validated in three real refurbishment projects in Hungary, Finland and Spain where the involvement of all the stakeholders in the design .process, will be evaluated and specific activities will be dedicated to inhabitants and users
