LowEx symposium: interim results for low-exergy projects

Abstract

Date: 28-29 October 2009

Location: Kassel

The LowEx consortium, which is supported by the German Federal Ministry of Economics and Technology as part of the EnOB research initiative, takes stock: a symposium on low-exergy systems and the LowEx projects is being held on 28-29 October 2009. The event is organised by the Fraunhofer Institute for Building Physics (IBP) in conjunction with the Fraunhofer Institute for Solar Energy Systems (ISE) and the E.ON Research Center at RWTH Aachen University.

More details

In recent years the LowEx consortium has been working to develop new and innovative heating and cooling systems for buildings which feature higher efficiency and the capability of using more renewable and natural energy sources. The consortium aims to develop and investigate new systems that can better utilise the quality of energy – the exergy.

Introduction

• Strategies for increasing energy efficiency and the increased use of renewable energy sources for heating and cooling buildings, Prof. Gerd Hauser (Fraunhofer IBP)
• Aims of the Federal Ministry of Economics and Technology’s thematic LowEx consortium project, Jürgen Gehrmann (Project Management Jülich)
• Exergy and economy – optimisation strategies for energy systems, Prof. Georgios Tsatsaronis (TU Berlin)

Development and application of exergetic evaluation methods

• Static exergetic evaluation methods, Herena Torio (Fraunhofer IBP)
• Dynamic exergetic evaluation methods, Dr. Joachim Seifert (TU Dresden), Alexander Hoh (ERC, RWTH Aachen University)
• Exergy analysis of solar cooling, Dr. Hans-Martin Henning (Fraunhofer ISE)
