The workplan is composed by 9 Workpackages (WP) including specific tasks that will be performed along the 36 months project duration. WP1, 2, 3, 4, 6 and 7 include Research anad Technological Development (RTD) activities, WP5 includes DEMO activities, WP8 OTHER activities, while WP9 Management (MGT) activities.

WP1 (Value Chain) is aimed at the definition of the Gas Absorption Heat Pump (GAHP) system’s engineering requirements for each “homogeneous area” within Europe, enabling the identification of the main issues, stakeholders and limitations to be overcome in the relevant geographical valuechains. Such activities are supporting the optimal integration of GAHP technology into building retrofitting industry. This WP is also aimed to develop a building retrofitting valuechain, investigating the roles and framework for the different suppliers, integrating the added value associated to the implementation of the GAHP System as well as to identify the appropriate GAHP System business requirements for an optimal diffusion of the technology. Starting from the engineering requirements defined in WP1, an Appliance will be developed in WP2, capable to achieve stability in efficiency across entire modulation rangebased on a pre-existing thermodynamic know how and sealed circuit technology developed by Robur. This WP will also address the technological barriers which prevent GAHP equipment from becoming the most suitable heating technology for retrofitting in residential applications and also the resistance factors to installation of outdoor equipment in residential areas by achieving appropriate level of thermal insulation and acoustic quietness. The control features that enable GAHP technology to flexibly adapt to different application environments will be also developed.

WP3 will be dedicated to the System development. This task will aim to guarantee, through a holistic approach considering emission, storage, distribution, control and integration with other energy sources) that the GAHP System will maximize efficient use of the energy within the overall building. Further to this, WP4 will aim at the Lab Performance Verification trough testing of GAHP Appliances and Systems according to European international and national standards at the lab scale, performance characterization under simulated load patterns, characteristic for the different typical conditions in the framework of the real application fields. Existing test protocols specific for GAHP will be reviewed and improved, in order to define a solid background of norms and standards for the future deployment of the new generation of GAHP Systems. Performances of GAHP Systems strongly depend on their practical implementation (selection of application, planning, control, hydraulics, enduser behavior, etc.).

Therefore, in WP5 (Demonstration and Field Testing), testing in real field applications will be performed to deliver:
(i) Validation of GAHP technology in a variety of retrofitted applications that represent of a large portion of retrofitted buildings typology.
(ii) Validation of GAHP performance in real applications;
(iii) third party recognized data for standardization and regulation activities (WP4);
(iv) experimental data for validation of the Decision Support System (WP6);
(v) Feedback for overall GAHP System optimization (control logic, schematics, end-user interface, installer instructions, integration into building, etc.).

WP6 is aimed at the development of a decision support system tool, capable to assess the degree of compatibility of GAHP with the proposed heating applications and to provide performance figures in terms of environmental, energy and economic benefits.

WP7 will be then dedicated: to perform a Life Cycle Cost Analysis to evaluate the cost effectiveness of the proposed heating and DHW system compared with competing technologies, to evaluate any possible environmental, technical and social risks associated with the operation of the system in line of current legislation and Directives; to identify sources of risks and the potential overall impacts on living beings associated to the whole production, installation, operation and maintenance operations; to analyse the cradle-tograve cycle, and when possible cradle-to-cradle cycle of the whole GAHP system, of its appliances and of its performances with respect to the macro-system in which operates, and to compare results with environmental impacts caused by competing technologies. Along the project duration, dissemination activities will ensure visibility and increased awareness on the project concept, thus facilitating the use of foreground and the exploitation of the project results (WP8).

A Business Model, taking into account players, stakeholders and partners involved at different levels within the Value Chain will be also developed. Management activities will ensure transparency and effectiveness in the communication among the partners by linking together the project components and supporting the circulation of relevant information (WP9).
