Building thermal and electrical energy hourly time series

The results reported are the hourly thermal and electrical energy use for one year of a renovated five-floor small Multi-Family house with ten dwellings in different EU climates.

A simulation-based database organized in Excel files (one per each climate) collects the hourly thermal and electrical energy use in the considered reference building (a small Multi-Family house) in three EU climates: Nordic, EU Continental, and Mediterranean considering the HVAC system solution with room booster heat pumps (HPs) developed within Horizon 2020 HAPPENING project and two reference systems. 

The building, HVAC and on-site renewable energy production systems are modeled and simulated using TRNSYS as dynamic simulation software. 

The fact that this simulation work is performed in different EU climates allows to extrapolate indications about how the HVAC system solutions work in different EU climatic contexts.

Regarding the building, a small Multi-Family house is considered as it represents the target building for the HP-base solutions developed within the HAPPENING project. The building has five floors with two dwellings per floor with a floor area of 50 m2 each, for a total floor area of 500 m2. In terms of thermal envelope performance, a renovated building has been considered, with a yearly space heating thermal demand in the range of 70 kWh/m2/y in the Nordic and EU Continental climates.

Regarding the HVAC system solutions, the dataset reports the results obtained considering the cascade HP-based solution with room booster HPs developed in the project HAPPENING. In addition to that, a typical (reference) air-water HP system, and a gas boiler system are used as reference systems to assess and compare the HAPPENING system solution performance.

Regarding the on-site renewable energy production system, a PV plant has been considered. The presence of an electric battery is also accounted for to allow a more complete assessment of the interactions between on-site renewable production and HVAC system consumption, highlighting the effects, advantages, and disadvantages of having also an electric storage. The PV and battery system is considered in all HVAC system solutions (HAPPENING solution, reference air-water HP system, gas boiler system) to highlight the differences in the interactions between different HVAC system solutions with PV and battery.

The project deliverable D2.7, available in the material, reports more details about all the quantities included in the dataset, as well as a series of system performance analyses, both over representative weeks and on a yearly basis.

The research leading to these results has received funding from the European Community's Horizon 2020 Programme (H2020) under grant agreement n° 957007.
