Correct use of Thermodynamics starts with correct teaching of Thermodynamics. Unfortunately the word teaching is not well respected by people as experienced when technical papers that deal with teaching are rejected no matter what the content. As academicians, we have committed ourselves to teaching. Since Thermodynamics is such a fundamental topic, it must be taught precisely and practiced correctly."
This presentation addresses smart and efficient solutions for the future heating of buildings. The design of smart heating solutions is essential for the implementation of future sustainable energy systems for two reasons: First, savings in heat demands and heating infrastructures in the form of district heating have an important role to play in the task of increasing energy efficiency and thus making scarce resources meet future demands. And next, the heating sector carry one of the most important and least cost options of integrating fluctuating renewable energy sources into the overall system. To enable this, a holistic smart energy system must coordinate between a number of smart grid infrastructures for the different sectors in the energy system, which includes electricity grids, district heating and cooling grids, gas grids and different fuel infrastructures. As a case the presentation includes the results of the Heat Roadmap Europe studies, the first studies on the EU scale which combines geographical mapping of energy demand and supply in unprecedented detail with detailed energy system modelling. The results are recommendations for a redesign of the European heat supply to achieve the goals of the Energy Roadmap 2050 by the European Commission, but at a lower cost.
