• The first activities in M1 of the Project dealt with the setting up of the fundamental requirements and the preliminary analysis of the Thermoss project demo sites.
• A dedicated check-list of the already installed equipment for HVAC, including sensors, actuators and BMS as well as a technical description of the building has been completed.
• The extra sensors needed have been defined. For these sensors, a detailed deployment plan has been defined to coordinate the installation work performed by the local installers.

• The requirements for data protection considering potential sensitive data of the involved households have been defined.
• In the second part of the first year, a library of state-of-art technologies for heating and cooling has been prepared that best suit for different geo-clustered building typologies.
• The preparation of the building and district-level modelling and simulation environment started in M6. The existing simulation environment DIMOSIM was adapted to the solutions deployed in the THERMOSS project. The DIMOSIM simulation tool allows the transient calculation of energy flows in a district with local or centralised (e.g. district heating) energy solutions, including waste heat.
• A sizing toolbox to determine the retrofitting package parameters and solutions has been developed. The toolbox considers the building typology as well as the climate, the building thermal needs and the type of technological package chosen.
• A preliminary assessment of primary energy savings for the 6 demo sites has been estimated from 14% to 72%, with non-renovated envelope of the buildings. The expected average of the energy savings is 27% which show that the THERMOSS objective of 20-30% energy savings may be reached in most demo sites provided the hardware heating system is complemented with suitable envelope renovation and on-demand heating control.
• The preparation, delivery and installation work for prototypes testing at CEA INES have been completed by Bosch and CEA. The Solar and Air source Heat Pump (SHP) and Heat Interface Unit (HIU) tests are completed.

• Specifications of 2-way-substations systems have been defined, with the selection of 3 possible architectures. One architecture has been chosen for further model and design tasks. The 2-way-substation progress may lead to the development and industrial manufacturing of one prototype.
• During the last 18 months the involved partners of WP4 have focused on the organisation of the open and multiscale platform for data collection, monitoring and management, through the development and the integration of optimization algorithms.
• In cooperation with WP5, data from the installed sensors are being collected in the database in real time. Data transmission through VPN connection is set for UK and Spanish demosites. Dedicated access using username and password has been granted to the involved THERMOSS Partners. Moreover, historical data from existing databases are being integrated in the database.
• Demosites in UK, Spain and Riga are now preparing the upgrade phase in all details (technical, financial, legal, etc.).
