Challenge / Goal
Through the GrowSmarter project, several new energy technologies have been implemented in the Mülheim district including charging stations, battery storage, renewable energy generation, and smart home systems, Hence, the goal was to have a smart energy management system which increases teh degree of self sufficiency of the buildings with respect to energy demands along with facilitating the use of more renewables.
Siedlungsmanagement is an intelligent management system to optimise energy and heat consumption. It interconnects internal (photovoltaic, heat pumps, battery storage) and external (district heat) energy producers.
Based on information gathered from meters installed throughout the building, Siedlungsmanagement can measure what energy is currently being used within each apartment and can predict future energy consumption. It uses this information to optimise the energy production and consumption in order to reduce the need for external energy from the grid. The Siedlungsmanagement software optimises the operation of the systems
based on the load forecast which is calculated using consumption and
production data. The electricity from photovoltaic panels is used mainly to supply the heat pumps. Any excess electricity will feed into the tenants’ own power supply (Mieterstrom).
Once local electricity demand has been satisfied, any residual current will be fed into the grid and remunerated through the German renewable energy act EEG.
Official meetings with tenants hels to explain the plan. The tenants were given the opportunity to switch to buildings not involved in the project.
