The GEOBIM Platform

In the GEOFIT project, heating and cooling components design and integration are developed for the different layouts and demo-sites and comprise a detailed design and description of the different subsystems or components to form a complete system. Key elements and components, as well as their specifications, are being developed and inventoried as part of the GEOFIT project activities. As in previous work, the deployment of low-invasive risk assessment, site-inspection, and worksite-building monitoring techniques extend its use as a monitoring tool for geothermal based retrofitting operations and deploy novel tools enabling the view of assets in a cartographic or a geographical environment and comparing with the information stored into GIS collectors and the Web Map Services (WMS). A common data environment containing GIS/BIM models/sensor data allows users to locate, map, update and share objects and subsurface utility information simultaneously, contributing to the realization of a new “GEOBIM platform”. The objective of the GEOBIM platform is to assess and verify the integration of the GEOFIT solutions in specific cases developing the respective different BIM models over a geographical information layer, aiming at replication and modularity of the solutions, outputs for exploitation, impact assessment, and dissemination of the results. The implementation of the previously defined system is addressed for buildings with different typologies and energy demands. Then, integration of the conditions and the building’s engineering specifications are defined within the GEOBIM platform.

The GEOBIM platform considers the scalability and flexibility of the data integration and analysis tools development to support interoperability among the elements installed. The design inputs come from:

    1. Boreholes and ground excavations information
    2. Geothermal heat exchangers designs
    3. Ground source heat pumps designs
    4. Heat pumps designs
    5. Heating and cooling systems designs
    6. Sensors information
    7. Simulations data

By covering the 7 dimensions of the #BIM approach, the GEOBIM platform implements the following functions:

  • Project visualization
  • Data management
  • Demo-site analysis functions
  • Geothermal performance
  • Heating/Cooling performance
  • GEOFIT assets management
  • CAPEX
  • The lifecycle of systems and assets

Within the GEOBIM platform development (understood as a common data environment), model-based cooperation is the advanced portrayal of the general GEOFIT development process. This portrayal is made in collaboration with the different partners involved in the design, modeling, construction/fabrication, installation, and commissioning, who utilize different CAD-based tools. The Common Data Environment (CDE) is characterized as a typical advanced task space, which gives very much characterized collaborative territory to the undertaking partners joined with clear status definitions and a strong work process portrayal for sharing and endorsement forms and objects data.

Abstract: This paper presents a novel Reduced Order grey box Model (ROM) methodology, based on a Resistor-Capacitor (RC) network, which supports the creation of the baseline energy consumption and the estimation of energy savings due to Energy Conservation Measures (ECMs) under the Measurement and Verification protocol. Within this scope, a description of the RC network, including a calculation of the parameters’ needed to execute the ROM, are presented. This ROM methodology is demonstrated on an educational building located in Sant Cugat, Spain as part of the H2020 GEOFIT project. The results presented in this paper demonstrate that the ROM is sufficiently accurate for the creation of the baseline energy consumption and for estimating the energy savings of different ECMs.

Abstract: The Italian building stock consists of buildings mainly constructed until the mid-20th century using pre-industrial construction techniques. These buildings require energy refurbishment that takes into account the preservation of their architectural heritage. In this view, this work studies an innovative integrated modelling and simulation framework consisting of the implementation of Historical Building Information Modeling (HBIM) for the energy retrofit of historical buildings with renewable geothermal HVAC system. To this aim, the field case study is part of a medieval complex in Central Italy (Perugia), as representative ancient rural offshore architecture in the European countryside. The system involves of a ground source heat pump, a water tank for thermal-energy storage connected to a low-temperature radiant system, and an air-handling unit. The building heating energy performance, typically influenced by thermal inertia in historical buildings, when coupled to the novel HVAC system, is comparatively assessed against a traditional scenario implementing a natural-gas boiler, and made inter-operative within the HBIM ad hoc platform. Results show that the innovative renewable energy system provides relevant benefits while preserving minor visual and architectural impact within the historical complex, and also in terms of both energy saving, CO2 emissions offset, and operation costs compared to the traditional existing system. The integrated HBIM approach may effectively drive the path toward regeneration and re-functioning of heritage in Europe.

Abstract: Italian cities are mainly constituted by buildings constructed until the mid-20th century by pre-industrial construction techniques. A HVAC system for the energy retrofit of historical buildings is evaluated when applied in the case study of Sant’Apollinare. It consists of a ground source heat pump a water tank for thermal energy storage connected to a low-temperature radiant system and air handling unit. The building thermal-energy behavior, typically influenced by thermal inertia in historical buildings, and the novel HVAC system performance interactions are comparatively assessed together with more traditional scenarios. Energy demand decreases by about one third compared to the pre-retrofit situation.

Thermally driven heat pump development and testing

By CNR – ITAE

Within GEOFIT project, a novel heat pump will be developed, able to efficiently exploit geothermal energy to provide heat under several climates and conditions. To this aim, a hybrid configuration for a reversible heat pump is being developed: it consists in the coupling of a gas-driven adsorption cycle with a vapour compression cycle. In this way, the temperature lift on the vapour compression cycle that is commonly employed is reduced and the energy consumption of the component is lower. The proposed solution, that is modular and based on commercial components, is suitable for both new installations and retrofitting applications, allowing a high flexibility.
