SIART and IDSGEORADAR perform structural monitoring at Sant Cugat pilot

From 27th to 31st July, SIART and IDSGEORADAR were at Sant Cugat pilot for structural monitoring, during the same week drilling works started. The goal was to perform structural monitoring before and during drilling, and see any impact in the school buildings.

IDSGEORADAR installed a Hydra-G system which monitored real-time measurements of sub-millimetric displacements in the administrative building and in the primary school. This system provides the high-accuracy and resolution radar technology. The system was accompanied by an optical and infrared HD camera providing real- time visual inspection of monitored area, draping radar data on a 3D model of the scene created using the radar system.

On the other hand, SIART installed several accelerometers in both buildings, administrative and primary school, to monitor vibrations before and during the first drilling carried out on 31st July. The goal of monitoring before drilling works is to know the building frequency, and see, once the drilling starts, if it has changed due to the vibrations propagation throughout the terrain. Once data has been captured, SIART will analyze them and present some results.

Drilling works have started at the Sant Cugat pilot site

On 31st July, Catalana De Perforacions (CDP) started the drilling works at the Sant Cugat demo site. The design of the geothermal field consists of 12 boreholes up to 120m deep and one Horizontal Directional Drilling (HDD).

While drilling the first well, some problems with the ground material, mainly clays, and the groundwater level at depths beyond around 60 meters were faced. The borehole heat exchangers are double U PERC 100 SDR 11 PN16, with a diameter of 32mm.

On the other hand, on 3rd of August, the works related to the horizontal connection between the collection chamber and the plant room where the Ground Source Heat Pump (GSHP) will be installed, also started.

These works, including the geothermal field and the horizontal connection between the chamber and the plant room, should be completed on 31st August according to schedule.

Fourth Assembly in Bordeaux

Bienvenue a Bordeaux! The most elegant city in France! Last week we were at the Geofit 4th General Assembly where we had the chance to share all the advances achieved since the last meeting.

We managed to get into intense planning and discussing agenda, mostly related to very important issues regarding the implementation of the pilots and how the technical solutions and legal issues could be approached. 

We found out, for example, of an interesting opportunity involving the different types of soils in the five different pilot sites. Drilling on different soils are options that can be explored and harnessed for the project interests.

The assembly also dealt with technical issues that will affect the activities scheduled for the next six months.

 

 

We also visited the demo site in Talence, in the very same building where we carried out the meeting. Our host (SAED) kindly showed the space where the future Geofit installation will be placed. It was almost as being on a living lab! Technical discussions and problem solving for the heat pump installation were part of the second day too.

 

 

 

 

The weather wasn’t very inspiring but we managed to get a very clear path for the next six months and everyone left with a positive feeling facing the new work roadmap. Merci la France!

 

 

 

Geofit Presentation Video

Here is the first video of Geofit, a video that presents the project and launches, with its premiere, the Geofit video series, which will include interviews, updates on demo sites, and will last until the end of the project.

This video presentation of motion graphics explains the context from which the European project Geofit arises: the environmental problem and the barriers and difficulties it faces, as well as the effective and integral solutions provided by the project to overcome them. It also describes the characteristics of our geothermal retrofitting systems and our innovative tools, methods and technologies.

Finally, the video presents the pilot sites where the Geofit systems will be installed to demonstrate the results and all the countries that make up our consortium.

The video is uploaded to Geofit’s YouTube channel, so that everyone can share and help us spread the word about it!

Remember that very soon our first newsletter will be published, with more news.

GEOFIT WORKSHOPS: Galway & Aran Islands

At the end of January we held two workshops in Ireland linked to two of our pilot sites, one located in Galway and the other in the Aran Islands. These pilot sites have different characteristics and represent different challenges for the demonstration of our project. In this post we will talk about the development of the workshops, as well as these two pilot sites, so that they can be better known.

Geothermal Energy in Ireland & the GEOFIT solution

On January 24th was held at National University of Ireland, Galway, a CPD Event open to the public on Geothermal Energy in Ireland and the solution of the GEOFIT project. The presentation was led by Ric Pasquali, President of the Irish Geothermal Association, and followed by talks on the GEOFIT project by Thomas Messervey from R2M and Gisela Soley from COMSA.

On Forecasting Energy Demand in Buildings

Article by Eurecat

Building Energy Demand Forecast Methodology (EDCE)

For the optimal sizing and determination of the HVAC system in a building, the precise calculation of the energy demand is an essential task, especially in cases of geothermal installations, due to the fact that the effort and the costs of any afterwards modification are high. Thus, the initial calculation and dimensioning of the installation are crucial to guarantee that the expected system’s performance is achieved.

Nowadays, the dimensioning of a building’s installation can be made in 3 different ways: i) The use of empirical methods based on energy demand estimations, ii) use of real operation energy consumption profiles (acquired by the building’s SCADA system), or iii) use of detailed building energy simulations to accurately characterize the energy requirement of the building.

Workshop in Perugia

From November 21 to December 6, 2018, a workshop was held at the Perugia demonstration site with the following objectives: to establish a channel of communication with local stakeholders, define their needs and requirements, include them in the design and finally gather information on the existing building. The workshop was conducted mainly with people who are directly involved in the building.
