Fraunhofer - IBP


Fraunhofer research activities are application- and results-oriented. The organisation pursues the implementation of innovative research findings in industrial and social applications. Its work is based on a dynamic balance between applied basic research and innovative development projects. The Fraunhofer Institute of Building Physics is one of over 50 research institutes of the Fraunhofer-Gesellschaft and deals with research, development, testing, demonstration and consulting in the fields of building physics, including indoor climate and preservation of building structures. The Department of Heat Technology focuses on energy conservation strategies such as energy-efficient building components and building service systems including renewable technologies.

The non-profit research institution, founded in 1949, is recognized as an organisation guaranteed by the Federal Republic of Germany. As it stands today, the Fraunhofer- Gesellschaft has attained a size (more than 10000 employees, turnover more than 1 billion Euro/year) and influence that makes it an undisputedly vital element in Germany’s industrial and scientific landscape. The turnover of the Institute for Building Physics in 2008 was 17.3 million Euro, generated by 136 regular employees.

The Department of Heat Technology is doing research and development in the field of energy-efficient buildings and community systems. Our scientists design, supervise and assess low-energy buildings, low-entropy buildings, 3-liter-houses, zero- heating energy houses and surplus energy houses and entire housing estates. They prepare energy-efficient renovation concepts for existing buildings and implement these into practical construction solutions. The working groups develop and investigate façade, heating, ventilation, solar, hybrid, storage, low-entropy and energy supply systems, designed for practical use in buildings.

Moreover, the department calculates total energy balances, including the life cycle analysis of buildings and heat supply systems, and analyses and assesses energy saving potentials. A focus is also on air flow and on the temperature performance of buildings in summer. Our scientists compute and measure lighting and the daylighting supply in buildings and are engaged in the assessment of mould growth. The department of Heat Technology develops and maintains computer-aided planning tools and information systems, in addition to integrated national and international demonstration and standardisation projects, as well as guideline panels.

The Department participated and still participates in leading positions in the following indicative projects:

The main activities of the department focus on:

Some key publications to which the department contributed are:

  1. The Energy Concept Adviser—A tool to improve energy efficiency in educational buildings. (
  2. Airtightness requirements for high performance buildings. (
  3. Executive summary report on the interim conclusions of the Concerted Action supporting transposition and implementation of the Directive 2002/91/EC.

Fraunhofer IBP is a founding member of INIVE and has joined this network of
excellence for the exchange of information on red-hot research outcomes and for working together with other leading organisations in high-level international projects and supporting activities.
