Deliverable 5.1 developed reduced order and transient dynamic models for three GEOFIT demonstration sites, i.e. San Cugat in Spain (Section 1), Bordeaux in France (Section 2) and Galway in Ireland (Section 3). The development of these models is part of the approach to select, design and integrate the GEOFIT Enhanced Geothermal Systems / Ground-Source Heat Pumps into the building according to its characteristics. The work presented here shows the capabilities of reduced order and transient models in building performance prediction and optimisation, as well as their flexibility to be used in building retrofit.
Structural Monitoring (SM) has a central role within GEOFIT. On one side, its results are expected to verify that the installation of a geothermal plant is painless for the target existing building. On the other side, going in depth in the governing mechanical model, one demands to structural monitoring: the knowledge of the excitation source, the verification of the soil propagation pattern and the building signature. All these aspects require the availability of pilot sites.
The Sant Cugat pilot site cover the “Els Pins del Vallès” School. At the end of July of 2020, there was a gathering in Sant Cugat of some GEOFIT partners: the pilot study responsible, the drilling
operator and the structural monitoring expertise.
This deliverable consists of two main chapters. In Chapter 2, the activity of the week of joint operations is reported. The pre-drilling data collection is well separated from that carried out the last day when the drilling machine was operative.
In chapter 3, one distinguishes three main parts. The characterization of the drilling machine, the vibration propagation along the soil and the identification of the frequencies aggressing
one of the buildings of the educational complex of constructions.
The focus is on the comparison between the signals recorded in the pre-drilling stage and in the drilling phase.
The intent of WP6 is to carry out an assessment of the different scenarios and to demonstrate the economic feasibility of the GEOFIT developments thanks to structural and HEX/EGS retrofitting. These goals shall be reached out through the implementation of a so called GEOBIM platform. Taking advantage of its capabilities regarding the data integration and visualization, the GEOBIM platform
provides the following functionalities:
• the tracking of the construction processes
• the related costs of the construction (retrofitting) projects,
• the energy demand/production (from estimations and simulations data),
• the efficiency & sustainability of the new systems installed
• and the Assets Management/Maintenance
Moreover, through this tool, this WP will allow all necessary stakeholders within the GEOFIT project to take part in the decision-making, development, and assessment in a user-friendly, easy, and efficient way thanks to the use of open format and cloud applications.
This deliverable D6.5 defines the first stage of implementation of the GEOBIM platform by applying BIM methodology following open standards such as IFC (Industry Foundation Classes) and in accordance with European BIM standard-specification organisation such as the OGC, BuildingSmart, etc.
This report provides description of the thermal comfort effects of the proposed low-temperature heating (LTH) and high-temperature cooling (HTC) systems in the pilot sites of Aran Islands and Sant Cugat. The pilot sites, the studied heating and cooling systems and the used modelling software are described. Suggested LTH and HTC systems are simulated and the results are compared with a baseline scenario. The results are presented and discussed. The simulations show that in the case of Aran Islands, the suggested hybrid heating system could potentially improve the thermal comfort of the occupants significantly while reducing the required supply temperature. In the case of Sant
Cugat, the results show that installing either of the studied types of cooling systems would clearly improve the thermal comfort of the occupants, with the radiant cooling system slightly outperforming an all-air system. Real-life performance evaluations will be included after the studied system being installed in pilots in the next version of the deliverable.
The goal of WP3 is to develop an integrated design framework for novel ground (slinky/earth basket) type shallow heat exchangers. This design framework, based on existing and new models of heat transfer and on experimental data, will be implemented in a design- and engineering calculation tool to support the implementation of these new technologies in the market.
This deliverable provides a description of the engineering tool developed in WP3. The purpose of the engineering tool is to provide a consolidated methodology for the design of different ground heat exchangers. The engineering tool provides:
- Calculation of the temperature response of different types of ground heat exchangers to an energy load.
- Methods for sizing of different types of ground heat exchangers.
- Calculation of pressure drop in the ground heat exchanger.
- User interface to select and define the ground heat exchanger and associated parameters, present results of the design calculations and a framework for project / design management.
The engineering tool has been developed in the python programming language. The tool has been validated by comparison with other calculation methods and by comparing with data collected in the Geofit project by partner AIT.
The design framework (deliverable D3.2) defined the goals of the (thermal and hydraulic) design (especially sizing) of the ground source heat exchanger, as a function of different boundary conditions (building energy demand, soil thermal parameters, required system performance etc.). The engineering tool provides the calculation methods for the overall system design and will support the engineer in the choices of heat exchanger technology (vertical, horizontal or earth basket/slinky) and other design parameterizations.
This deliverable describes the engineering tool developed in WP3, this version (October 2020) provides background information on the core of the engineering tool, specifically the different calculation modules as well as a first draft of the design project relational database and graphical user interface.
It is the first implementation of a tool that allows all different types of ground heat exchangers to be evaluated in one consolidated environment.
This document is the updated version of previous Deliverable D8.1. It includes the analysis of the applicable standardization landscape. It provides useful information for the development of the
project and its work packages, by identifying the existing standards and technologies and the ongoing developments (at European and international levels) in the fields related with GEOFIT.
This analysis of the standardization landscape includes the identification of the related standardization committees and organizations involved.
Additionally, it includes a strategy for GEOFIT’s contribution to standardization and a description of the types of standard documents which could be implemented.
GEOFIT website was uploaded at www.geofit-project.eu on Wednesday, June 27, 2018, according to the DoA, the website was to be published on month 6, so it was published on month 2, with an advance of 4 months. A draft version was ready for the KoM so partners could properly provide feedback to have an operative public version as soon as possible. The effort was motivated for establishing the brand and identity of the project as early as possible to attract interest and focus the consortium on its key messages. This also allowed us to have the website up and running for the Sustainable Places conference, where a GEOFIT poster was presented. The first version of the project website contains the fundamental aspects of the project and enables the newsletter and email communication channels. This document resumes the implementation of the website and details the process to report changes.
Structural Monitoring (SM) is widely recognized as the basis for any sort of diagnostics in assessing the operating conditions of structures and infrastructures. Through the continuous technological development of data collection and processing tools, SM allows one to evaluate the structural characteristics and the level of damage of any structural system, giving the technicians the ability to predict the structural response deterioration along time.
In principle, attention is focused on the possibility of rapidly acquiring data from different instruments in a nearly simultaneous way, the target being the realization of a reliable control map. Care is devoted to those emerging technologies capable of monitoring the structure remotely and without contact.
Monitoring the health status of a structure (SHM) means to generate the potential for increasing its level of safety in its various life stages. By monitoring an existing facility, by carrying out surveys and tests, one obtains a sequence of structural responses to external excitations. Comparing one with the other, one can detect damage-induced modifications of the response. Within the GEOFIT project, the source of the potential damage to be detected is related to the drilling activity necessary for the installation of the designed geothermal plant.
Shallow geothermal energy (SGE) technology is an emerging market and is poised to sustain growth based on its feasibility around the globe irrespective of terrain. This can be duly attributed to awareness of public towards climate change and need to switch to renewables in addition to long term objectives of government policies for decarbonizing residential energy consumption with special focus on heating and cooling.
The deliverable aims at a public understanding of the latest trends in the SGE market at global, European, and selected national scales. This report sets a platform for strategizing future business model development and supporting the exploitation activities. The reports also address the key issues that is set to influence the GEOFIT acceptance which starts with an overview of SGE systems and current trends in worldwide canvas and European perspective with special focus on four identified pilot countries. This report further analysis the barriers, the value chain and the importance of synergy between different stakeholders that will ease the adoption/acceptance of GEOFIT in SGE or the heating and cooling market. The preliminary market potential assessment sets a foundation to further assess the pilot site countries under a business case format in subsequent months of the project. The GSHP competitor analysis was carried out based on functionality of well-known GSHP brands available in the European market.
The scope of this deliverable is a general overview of SGE-related topics that serves as a foundation to map the market analysis and market watch activities within GEOFIT to exploitation planning by going deeper into each key exploitable result as a distinctive market to be explored.
