“…On the other hand, the values of time lead and time lag for the building and the underground room have been calculated by matching temperature waves obtained starting from heat transfer of Equation 2 and multiyear experimental measures of internal temperature, with four sensors inside the wine cellar and two sensors below the building and beside the cellar (Tinti et al, 2015).…”

Ground temperature and hydrogeological conditions are key parameters for many engineering applications, such as the design of building basements and underground spaces and the assessment of shallow geothermal energy potential. Especially in urban areas, in the very shallow depths, it is diffi cult to fi nd natural undisturbed underground thermal conditions because of anthropic interventions. The assessment of underground behaviour in disturbed conditions will become more and more relevant because of increasing awareness to energy effi ciency and renewable energy topics. The purpose of this paper is to show a three-dimensional representation -based on models calibrated on experimental data -of the underground thermal behaviour aff ected by a building in a rural area in Italy. Temperature varies in space and time and it depends on ground, climate and building characteristics, and all these parameters are taken into account by the seasonal periodic modelling implemented. The results obtained in a context of low urbanization indirectly suggest the importance of these eff ects in dense urban areas; taking greater account of these aspects could lead to improvements in the design of underground spaces and geo-exchanger fi elds for geothermal energy exploitation. KeywordsThermal impact of buildings, ground temperature, shallow geothermal energy, heat transfer via the ground.

“…Die Sektproduktion nach der Jahrhunderte alten "Méthode traditionnelle" (Champagnermethode) ist geprägt durch die zweite Phase des Gärprozesses, die als Flaschengärung stattfindet. Im Anschluss an die alkoholische Gärung vom Traubenmost zum Grundwein wird dieser in Flaschen abgefüllt und nach der rund drei Wochen dauernden eigentlichen Gärphase für mindestens 15 Monate zur Reife "auf der Hefe" gelagert [2]. Ein wesentlicher Faktor für die optimale Lagerung während der Reifezeit ist die Lagertemperatur von rund 10 bis 12 °C.…”

Für den Neubau der Produktionsstätte eines Getränkeherstellers war es erforderlich, ein Lagervolumen für rund fünf Millionen Flaschen als gekühltes Rohsektlager bereitzustellen. Die maximalen Temperaturen durften aufgrund der Qualitätsanforderungen im Produktionsprozess 14 °C während der Sommermonate nicht überschreiten. Um möglichst hohe Energieeffizienz zu erzielen und eine ganzjährige Beheizung beziehungsweise Kühlung zu vermeiden, sollte das Lager natürlich konditioniert werden: Durch explizite Kopplung des Gärlagers mit dem angrenzenden Erdreich wurde dessen Pufferwirkung über ungedämmte erdberührte Wand‐ und Bodenbauteile aktiviert. Auch das Lagergut selbst wurde als thermische Speichermasse in der Auslegung berücksichtigt. Gleichzeitig wurde die verbliebene thermische Gebäudehülle dahingehend optimiert, dass die auftretenden Wärmegewinne und Wärmeverluste zur Außenluft auf ein Minimum reduziert sind. Der Nachweis der Gebrauchstauglichkeit erfolgte mittels gekoppelter transienter thermischer Gebäudesimulation. Es konnte gezeigt werden, dass – selbst unter Annahme erhöhter Außenluft‐ und Erdreichtemperaturen aufgrund des Klimawandels – bei Ausführung von Außenwänden und Dächern in höchster thermischer Qualität auf eine aktive Konditionierung des Lagers vollständig verzichtet werden kann.

Referring to the wine sector, in the Mediterranean area, most of the wine farms make use of unconditioned above-ground buildings constructed without a specific attention to temperature control, where indoor temperatures easily show trends in disagreement with correct wine-ageing and conservation. Moreover the suitable temperature ranges can differ from wine to wine, and are considerably different from ideal temperatures for human comfort. This study aimed at testing the effectiveness of different architectural elements in improving the thermal behaviour of unconditioned farm buildings, by means of energy simulations validated on an Italian case-study, comparing the data provided by the simulations with different temperature ranges. Results showed the building thermal performance depends on the chosen intervals, some solution played negative or positive role according to the analysed range and in general roof and wall interventions were more effective than orientation and solar shading, and the combination of more strategies allow to achieve improved results.
