A modular, integrated energy system model is being developed to help municipalities and urban planners implement climate protection measures. The modular planning instruments will analyse the electricity, heating and mobility sectors, the expected energy and CO2 flows, and the various energy saving potential. The EN-Easy software tool, which will be made available on completion of the project, can be used for any balancing area – whether a neighbourhood, district or city – and is intended for use by city planning departments, district managers and also in participation processes.

The aim is to develop a planning tool that will help municipalities and urban planners implement climate protection measures. Here the “buildings” and “transport” areas will be linked via a holistic energy system model. This enables simultaneous consideration of the electricity and heating market as well as the connection with the mobility sector. The interactions between the electricity, heating and mobility sub-markets can therefore be recorded.

Karajan Ingenieure is responsible for developing the demand side for the transport sector. To this end, the transport structure for the complex Sustainable City Information Model (SCIM) will be mapped and measures in the transport sector developed and integrated into the simplified EN-Easy tool. Drees & Sommer is providing demand-side structural data for the SCIM with the help of building simulation models and is developing the quantification of climate protection measures in the residential and non-residential sector for the EN-Easy tool. Institute of Energy Economics and Rational Energy Use at the University of Stuttgart (IER) is further developing the energy system model (TIMES Local), linking the aforementioned modules and investigating the interactions between the electricity, heating and mobility sub-markets for different balancing areas. For the En-Easy tool, the IER is developing climate protection measures that are not part of the building or transport sector.

 

Milestones and successes

The applicability of the planning tool for variable balancing areas has been investigated by means of two case studies – in a sample district in Metzingen and in a development area in Berlin-Tegel.

Application

The planning tool supplies the target values and also serves as a monitoring tool. Its modular design enables it to be easily adapted to area sizes, objectives and local conditions. The intention is to demonstrate this using case studies. The EN-Easy tool will take into account both the use of prepared statistical data for Germany as well as the additional input of local and GIS data by the later users in the municipalities. The aim is to facilitate its use by urban planners for implementing climate protection concepts, while at the same time enabling them to map complex user requirements. The EN-Easy planning tool therefore enables an integrated analysis of the expected energy and CO2 flows of any balancing area and at the same time provides indications for possible energy efficiency measures and their respective energy-saving potential. An economic consideration of the measures for residential and non-residential buildings and transport is also being carried out.
