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). Image 1: location of the 12 boreholes. While drilling the first well, some
The stakeholders in a building retrofit project often are unfamiliar with shallow geothermal energy (SGE) technology and potentially have conflicting requirements [MUSE, 2019]. The following table shows the influence and interest of (in)directly involved stakeholders of typical SGE for building retrofit projects, in the framework of suggested management principles. Building
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
Article by Henrikki Pieskä (KTH) and Qian Wang (Uponor) A heat emission system is an integral part of a building’s HVAC-system. Heat emission system is the interface between the heat source and the building user, so a proper design is essential both for energy efficiency and user comfort. The objective
By IDS GeoRadar Geothermal based building retrofitting involve complex operations, such as drilling and digging, which must be considered as risky activities both for the excavation crews and the buildings close to the work area; managing these risks is one of the key objectives for GEOFIT. In fact, digging up
By Sergio Velásquez – IDP GEOFIT project represents a challenge and an opportunity for a geothermal based retrofitting of existing buildings. It covers several disciplines in terms of the processes developed and the data provisions at architectural, physical, geographical, technological, contractual, economical and life cycle levels. In general terms, physical
By Fahrenheit In the field of adsorption heat pumps, there are currently few studies on the combination with compression heat pumps and gas condensing boilers. Compared to conventional compression heat pumps, this concept offers a better EER and COP and makes it possible to use the optimum ratio between electrical
by Montse Vilaseca, EURECAT Drilling is a key technology enabling heat exchangers installation and plays an important role in the building industry, both in sedimentary as well as in rock drilling. Tools employed in drilling are known as drill bits, and are the responsible for mechanically penetrating and crushing the
From the 7th to the 9th of May the GEOFIT consortium gathered in Vienna to hold their third general assembly. The meeting was organised by AIT (Austrian Institute of Technology) in their premises located in Giefinggasse, which also put together a traditional Austrian dinner in the city centre for all
By Adriaan Brebels, i.LECO NV, Belgium For the different demo sites in the Geofit project a one-year pre-retrofit data-monitoring plan has been implemented. The data to be collected comes from different instruments and different sources. Locally, we measure the internal and external climate parameters (temperature, humidity, CO2, wind speed…) and
This project has received funding from the European Union’s H2020 programme under Grant Agreement No. 792210.
