At ifeu, a range of state-of-the-art modelling tools are available for the quantification of technology and societal developments, environmental impacts, course of action, and impacts of policy or social interventions.
TREMOD is a data and computing program used to generate high-resolution models of energy consumption, greenhouse gas and exhaust emissions from motorised traffic. TREMOD is used to model all forms of passenger transport (cars, motorcycles, buses, trains, aircraft) and goods transport (trucks, light commercial vehicles and tractors, railways, inland waterway vessels, aircraft).
VEHMOD, the vehicle simulation model developed by ifeu, makes it possible to calculate the energy consumption of road vehicles powered by electric drive in any driving cycles. Specific vehicles can be mapped on the basis of certain parameters to show the operating statuses of the components depending on the driving situation. Important environmental conditions such as the outside temperature can also be adjusted.
eLCAr depicts the environmental effects of motor vehicles with conventional and alternative powertrains throughout their entire life cycle. This is based on a hierarchical material flow model which contains the life cycle stations of vehicle manufacture, usage phase, vehicle maintenance, and vehicle disposal, including their respective upstream material and energy chains.
The spatial component plays a pivotal role in the assessment of heat supply options in the building stock. Key research questions on existing potentials can only be answered with a fine-scale spatio-temporal calibration of the long-term heat demand trajectory against local heat sources. For this purpose, ifeu collaborates with the Geomer GmbH and the GEF Ingenieur AG to develop and maintain the heat map, a bottom-up model of the energy classification and spatial distribution of all residential and non-residential buildings in the Federal Republic of Germany.
Domestic electricity model (EMOD)
The domestic energy model EMOD may be used to explore efficiency and sufficiency potentials from domestic electricity consumption, and to model domestic electricity consumption profiles with high temporal resolution. For the heat supply from heat pumps, tax strategies promoting electricity supply with a high proportion of self-generated electricity may be modelled and evaluated. Moreover, the modelling and evaluation of electricity supply for electric vehicles derived from photovoltaics or combined heat and power is possible.
The ifeu models for the production and processing of raw materials, semi-finished products and energy carriers allow a comprehensive characterisation of basic industrial processes and their associated environmental impacts. The wide range of input parameters renders the models highly versatile and applicable to many different situations. Thus, a diverse spectrum of questions may be answered.
