Valladolid, Spain

Building description: Constructed in 2021 this is a single family dwelling, 2 people family living there all year long. The building has two floors with a total extension of around 165 m2. Building has a category A on EPC.

Heating & Cooling system: Air-to-water heat pump connected to a radiant floor H&C distribution, also providing DHW. The building has a PV-roof facility. Thermal energy demand: 1.3 MWh/y for heating, 1.8 MWh/y for cooling, 2.1 MWh/y for DHW. Digital programmable thermostats are installed in all rooms (one per room). The thermostat acts on the thermostatic head of the radiant floor circuit, so the temperature in each room can be controlled independently.

Demonstration action:

• Hardware: Installation of the sorTES with a target capacity of 100 kWh, to support heating and cooling provision. The sorTES will be charged by integrated PtH solution to exploit onsite PV rooftop renewables as well as electricity from the grid, to increase the operation flexibility. Installation of a FractLES for heating/DHW and one for cooling both with a target capacity of 9 kWh. These short-duration storages will support the long-duration sorTES and will also balance the daily demand of the building. The ALGOW BEMS will be deployed as well
• Software: the WECoMP thermo-economic tool will be applied in the design phase of the validation.
