Multifamily housing with CO2 neutral electricity consumption
The project includes concept development and guidelines for establishment of combi PV/ battery storage systems in multifamily buildings. Consumption by residents and building operation will be managed and made visible through a communication platform providing intelligent interaction with power system. Measurements will show effect on user habits.
In project 346-048, an Excel-based design tool has been developed. The tool will, based on data on the building roof area, orientation, total electricity consumption, solar cell and battery storage prices, cost of buying and selling electricity, financing conditions etc., identify the best combination of solar panel area and battery storage capacity, that provides the most beneficial economic operation of the hybrid system for the residents. In addition, PV-BAT can calculate the financial consequences for residents when the battery storage is used dynamically in an intelligent interaction with the electricity network's need for flexibility.
PV-BAT has been tested in 12 different social housing units and has thus provided a basis for establishing a number of demonstration projects financially supported by the social housing fund.
Some of the partners involved in this project have subsequently received project support to further develop PV-BAT to also calculate the impact of more complex energy supply systems for single family homes and business purposes. PV-BAT is available in a Danish version as open source, which can be downloaded from ELFORSK's website at www.elforsk.dk from project number 346-048.
