“…The largely validated Type 1b was used for modelling flat plate solar thermal collectors (Banister et al 2014). Type 668 was used to model the water/water heat pump through interpolation of user-defined data, based on performance curves provided by manufacturers (Dott et al 2013). Type 557 was used to model the geothermal field (Hellstrom 1989;Ruiz-Calvo et al 2017;Li et al 2023) with the boreholes of diameter 40 mm and water flow rate of 0.483 l/s.…”

The integrated use of multiple renewable energy sources to increase the efficiency of heat pump systems, such as in Solar Assisted Geothermal Heat Pumps (SAGHP), may lead to significant benefits in terms of increased efficiency and overall system performance especially in extreme climate contexts, but requires careful integrated optimization of the different system components. In particular, thermal storages take a fundamental role in optimizing the integration of renewable energy sources and the system operation. This work investigates the potential design optimization of a SAGHP system in a mountain site by exploring many different alternatives to optimize the mutual relationship between the solar field, the geothermal field and the water thermal storages. This is done through an original simulation-based multi-objective optimization framework considering energy efficiency and economic feasibility, which allows appraising the impact of the different design alternatives on the overall system performance and on the dynamics of the different system components. Results identify a set of optimized system configurations that optimize the integrated exploitation of the different thermal sources showing a potential increase of the overall system performance leading to 34% lower global cost compared to the initial design. High robustness of the optimal design solutions is reported with respect to the current context of high economic uncertainty.

“…Simulations within the project TheBat (Thür et al, , 2017a are done for a single family house (based on the IEA SHC Task44 reference building; (Dott et al, 2012;Dott et al, 2013)) designed as low energy standard (RES45: 45 kWh/m 2 a space heating consumption, SH) at Innsbruck climate with thermal active mass by floor heating. The reference floor area is 140 m 2 , the room temperature is controlled to 21°C ± 0.5K and the domestic hot water (DHW) consumption at 45°C tap temperature is 2,175 kWh per year.…”
