THERMOSS proposes an industry-focused, innovation-intensive approach to ease and foster the introduction of cutting-edge heating and cooling technologies for building energy retrofitting at European level, targeting residential buildings and buildings connected to District Heating and Cooling (DHC) networks.


Work Packages

THERMOSS is structured into 8 work packages that will lead to an effective performance and development of the project

Definition of user requirements and result of validation strategy, and collection of data, deployment of critical sensors

Develop a geo-clustered building typology suitable for a variety heating and cooling technologies; develop, adapt and test a building and district level energy/thermal modelling platform; deliver a computerized tool suitable for energy simulations and assessments; ensure that the developed platforms and toolkits are interoperable with existing languages (such as gbXML, or IFC) and with existing tools; deliver a complete solution for building and district retrofitting.

Deliver tailored heating and cooling technology packages for DHC assessment and retrofit:

Hardware, Software connectivity interface, DHC integration parameter definition, and Technology Packaging Guidelines.

Develop the management algorithms at building and district level; Implement the communication strategy at building and district level; develop and validate the associated hardware

Deploy measurements instruments in selected buildings on test sites; collect the data for energy baseline assessment; deploy defined solutions on test sites for validation; collect the energy data after the deployment of the defined solutions


Develop a comprehensive energy assessment methodology suitable for the proposed technologies and wider applications in the target sectors; assess operational and functional efficiency of the developed technologies and carry a detailed energy audit; analyse the monitoring results and provide robust and technically feasible solutions to further improve efficiency and reach project targets; carry a financial impact assessment study and set up short, medium and long-term strategies that can maximise the economic impact, locally and globally.

Dissemination and business-oriented exploitation strategy.


Development Process

THERMOSS will follow a development process, composed of five main steps.

In order to promote the wide acceptance of new efficient heating/cooling production systems, it is proposed, through an open database, to publish available technologies, classified by building typologies and by European climates. The creation and the maintenance of such a database will rely on available technology catalogues in addition to the knowledge of technological experts and installers.

Given a typical building connected either to a gas distribution network or to a district heating network in addition to an electricity distribution grid, the figure shows that solutions for the improvement of global gas savings that still satisfy the building heating and/or cooling demand (including DHW production) rely on the energy efficiency in the grid and the presence of heat recovery from solar, ambient air or waste water at building level.

The proposed THERMOSS technology packages are defined according to European climates and building technologies. The sizing toolbox will allow, through an optimisation process, to define the solutions characteristics while taking into account European and national regulations and directives.
