In 2011, Calgary, Alberta based Borealis Geopower bought the geothermal rights to the Canoe Reach arm of Kinbasket Lake, near Valemount, British Columbia. New to Canada, a pilot project of a 2 megawatt geothermal power facility will begin within the next five years. The project is a positive addition to the area, as it is a non-polluting energy source with an effluent of clean hot water. This thesis proposes a maximization of this energy source by combining the power facility with an education center and bathing facility. Included in this bathing experience are ancillary cabins and paths to promote the users’ interaction and enjoyment of the project and landscape. Finally, this thesis develops a material strategy, choreographing the visitors’ experience of the geothermal resource within the site’s mountainous topography.

This thesis presents an experiment and an analysis that evaluates some of the long-standing assumptions in deep vertical borehole ground heat exchanger (GHX) theory. These assumptions neglect ground heterogeneity and depth variations in GHX output and the ground temperature response (GTR). This thesis describes an apparatus and an experiment that measured the GTR at several depths, times, and at two different horizontal distances from a GHX both during and immediately after its operation. This thesis also reports the temperature response data, which may not be available from other sources in such detail. The experiment showed that the GTR can be highly depth dependant. The analysis involved a parametric study to characterize the GTR by developing an effective computer simulation of the experiment. The analysis showed that ground heterogeneity significantly affected the GTR and the GHX output in this study. Furthermore, this GHX output showed depth and time, dependence.

In this thesis proposals for different designs of a borehole thermal energy storage (BTES) have been developed for the building DN-huset in Stockholm, Sweden. To build a BTES results in savings in energy costs by approximately 44 %, i.e. 2 million Swedish crowns annually. Furthermore, a BTES would reduce the annual environmental impact with roughly 75-157 tonnes of CO2 equivalents per year, depending on how the electricity consumption’s environmental impact is estimated. The payback period is about 11 years, including the warm-up period that is necessary before commissioning the BTES. The savings in environmental impact and operating costs are a result of energy being reused. During the summer heat is stored in the bedrock beneath the building for retrieval about half a year later in the winter, when there is a heating demand. In addition to developing proposals for different BTES designs the thesis also examines the influence of certain design parameters, conservative choices and operating conditions.

Im Freistaat Sachsen werden 7.500 Gebäude mit Erdwärme klimatisiert. Genutzt wird die Wärme aus der Tiefe vor allem bei Ein- und Mehrfamilienhäusern zur Heizung und Warmwasserbereitung. Bei Planung und Bau von Erdwärmeanlagen sind Aspekte der Qualitätssicherung und rechtliche Vorgaben zu beachten. Interessierten Bürgern, Planern und Bohrfirmen werden u. a. folgende Fragen beantwortet: - Welche Nutzungsformen der Erdwärme gibt es? - Welche Qualitätsanforderungen, Richtlinien und Gesetze sind einzuhalten? - Wie wird eine Anlage richtig geplant? - Wo und wie werden Bohrungen bei Behörden beantragt? Die Informationsbroschüre erscheint in 3. Auflage und ersetzt den Leitfaden für Erdwärmesonden.

Η γεωθερμική ενέργεια είναι μία ήπια, εναλλακτική και ανανεώσιμη πηγή ενέργειας. Η παρούσα εργασία έχει ως αντικείμενο μελέτης τα δύο από τα πέντε γεωθερμικά πεδία του Νομού Ξάνθης, αυτά της Νέας Κεσσάνης και του Νέου Ερασμίου-Μαγγάνων. Στόχος της εργασίας είναι να χαρακτηριστούν τα γεωθερμικά πεδία αυτά και να προταθούν πιθανοί τρόποι αξιοποίησής τους. / Geothermal energy is a clean and renewable source of energy. This project has to do with two out of five geothermal fields of Xanthi, those of Nea Kessani and Neo Erasmio-Maggana. The purpose of this project is for those geothermal fields to be characterized and to propose possible ways to be exploited.
