9 TRAINING OF EXPERTS FOR ENERGY RETROFIT AT THE FRAUNHOFER CENTRE FOR THE ENERGY-SAVING RENOVATION OF OLD BUILDINGS AND THE PRESERVATION OF MONUMENTS AT BENEDIKTBEUERN KILIAN, R.; KRUS, M. KILIAN, R.: Fraunhofer Institute for Building Physics IBP, Stuttgart - Germany. ralf.kilian@ibp.fraunhofer.de KRUS, M.: Fraunhofer Institute for Building Physics IBP, Stuttgart - Germany ABSTRACT In times of rising energy prices, growing ecological consciousness and climate change the saving of energy is becoming more and more important. But how can we save energy in historical buildings without detriment to their historical value? What possibilities are there for applying environmentally friendly measures under these special conditions? The Fraunhofer Centre for the Energy-saving Renovation of Old Buildings and the Preservation of Monuments at Benediktbeuern was founded with the idea of providing answers to these important questions. As an information centre providing expert advice it will deal with topics related to the renovation and preservation of historic buildings and monuments. In particular, the problems of energy efficiency and related structural damage as well as the application of sustainable materials and technology with regard to cost-efficiency will be addressed in research-cooperation with renowned European partners. The various problems, their possible solutions and applications will thus be demonstrated directly on the historic building Alte Schäfflerei itself; different heating systems and internal wall insulation will be realized and compared; regular exhibitions and guided tours are taking place on site. The scope of activities of the Fraunhofer Centre includes not only the model renovation of a significant historical building, but also micro-climate measurements, research on building services and materials as well as independent counselling on preservation and energy-efficient retrofitting. The most important aspect of the Fraunhofer Centre is the close interaction of craftsmanship, science and monument preservation as well as the use of new, innovative materials and technologies for historical buildings. For the first time, knowledge in building physics and experience in the fields of building maintenance and monument preservation are combined in a public information and counselling centre accommodated itself in a historical building. Architects, monument conservators, craftsmen, builders and stakeholders have a chance to obtain information and advice on energy-efficient renovation and monument preservation. Also a course on energy retrofit of historic buildings is offered in cooperation with the Bavarian State Office for the Preservation of Historical Monuments (BLfD). Furthermore the Fraunhofer Centre Benediktbeuern was involved in the development of a curriculum for training of energy consultants in the field of monument preservation. Our scientists are also teaching in courses offered by German Architects Associations and other training institutions.

In times of rising energy prices, growing ecological consciousness and climate change the saving of energy is becoming more and more important. How can we save energy in historical buildings without detriment to their historical value? What possibilities are there for applying environmentally friendly measures under these conditions? The Fraunhofer Centre Benediktbeuern was founded with the idea of providing answers to these important questions. As an information centre providing expert advice it will deal with topics related to the renovation and preservation of historical buildings and monuments. In particular, the problems of energy efficiency and related structural damage as well as the application of sustainable materials and of procedures with regard to cost-efficiency will be addressed. In response to the current demands of the European construction industry new research is needed, underlining the importance of such a demonstration centre on a European level Image 1: Front view of the Alte Schäfflerei before renovation, showing the main building in the middle, the northern building on the left. Benediktbeuern is one of the oldest monasteries in upper Bavaria, its roots going back to 8th century AD. After the 1803 secularisation, the researcher, inventor and entrepreneur Joseph von Fraunhofer (*1787, 1826) was working here in a glass workshop, where he also did his most important research on the so called Fraunhofer lines in the solar spectrum. Fraunhofer gave his name to the Fraunhofer Gesellschaft, which was only founded in Since 1930 the cloister is run by the Salesians of Don Bosco. The building Schäfflerei dates in the second half of the 18th century and belongs to the former craftsmen court of the monastery. At the Alte Schäfflerei or old cooperage barrels were made in the former times for the nearby brewery, which has become a youth hostel today. Many of the typical problems of an old building and all the related questions of restoration and refurbishment can be found here. It is therefore the ideal place for such a centre. The various questions and applications will be demonstrated directly at a real historic building. All works are done in close collaboration with the Bavarian State Office for the Preservation of Historical Monuments (BLfD). Currently different heating systems and interior insulation are More contents on

11 International Conference installed and compared. The scope of activities of the Competence Centre includes not only the model renovation of a significant historical building, but also micro-climate measurements, research on building services and materials as well as independent counselling on preservation and energy-efficient retrofitting. The most important aspect of the new Competence Centre is the close interaction of craftsmanship, science and monument preservation as well as the use of new, innovative materials and technologies for historical buildings. For the first time, knowledge in building physics and experience in the fields of building maintenance and monument preservation will be combined in a public centre for information and counselling accommodated itself in a historical building Image 2: View of the attic of the Alte Schäfflerei during roof renovation with a historic lift that is still in place. At the main building all historic tiles were recovered and reused. View of the upper floor where research on internal wall insulation is carried out. Architects, monument conservators, craftsmen, builders and stakeholders have a chance to obtain information and advice on energy-efficient renovation and monument preservation. The Fraunhofer Centre in Benediktbeuern will be facing the world wide challenge of energy efficiency in historic buildings by offering innovative solutions suitable in cooperation with renowned European partners. 2. Research and demonstration for Monument Preservation The Fraunhofer Centre in Benediktbeuern is aiming to answer amongst others the following questions concerning renovation and restoration measures: - Which historical and modern materials can be used? - How can historic walls be renovated? - Which aspects of monument preservation must be considered for energy retrofit? - What factors cause mould growth? - How can damage be avoided by adequate heating and ventilation?

12 - What kind of heating has a positive effect on the existing indoor climate? - When is thermal insulation reasonable and possible? - Which costs occur due to renovation measures? - What kind of financial support is available? 2.1. Areas of research and demonstration The interested public cannot only visit the demonstration and exhibition areas but will also get counselling and receive information material. Also training and further education in the fields of the above-mentioned topics (see also Table 1) are organized by the centre. Table 1: Topics of research and demonstration at the Fraunhofer Centre Benediktbeuern: Topics Thermal Building Envelope Temperature control / heating / HVAC Systems Ventilation Building constructions Structural moisture barriers / drainage Plasters Coats / Coatings Windows Specific Solutions - Internal / external wall insulation - Innovative materials (Vacuum insulation, Aerogel, etc.) - Renewable materials (Typha, etc.) - Reversible solutions - Heat storage capacity - Calculation methods (Glaser/ WUFI / DIN 18599) - Life Cycle Assessment - Wall heating - Temperierung wall heating - Radiators - Radiant panel heating - Air heating - Humidification / dehumidification - Control strategies - Energy production (Solar, geothermal, wood, etc.) - Air quality measurements - Controlled ventilation - Attic construction - Historic floor structures - Horizontal barrier / drainage - Vertical shoring - Injection methods - Clay sealing - Exotic solutions: ventilation capillary tubes, Electro-osmosis - Preservation of historical plasters - Cement and lime plasters - Restoration plaster - Thermal insulation plaster - Historical ones and their properties - Modern ones and their properties - Water uptake vs. diffusion - Preservation of historical windows - Improvement of thermal insulation More contents on

13 Constructive protection Noise control / room acoustics - Canopies - Constructive details (Window sills, drain pipes,etc.) - modular absorbers (separated or integrated) - Noise control of HVAC systems 2.2. Current research and demonstration projects at Benediktbeuern The various questions and applications will thus be demonstrated directly on a real historic building. All works are done in close collaboration with the Bavarian State Office for the Preservation of Historical Monuments (BLfD). Current demonstration projects include the thermal insulation of the attic floor, with a monitoring of temperature, relative humidity and heat fluxes inside the construction with sensor technology, funded by the Deutsche Bundesstiftung Umwelt (DBU). Also two large national research project funded by the German Ministry of Economy and Technology are situated at the Fraunhofer Centre Benediktbeuern looking at Innovative Wall Heating Systems and at Reversible solutions for Internal Wall Insulation. In the northern building four different heating systems are monitored and compared in questions of indoor comfort, prevention of moisture related damages and energy use Image 3: Application of an aerogel insulation plaster by machine. The upper plaster layers are separated from the original building surface by a protective, reversible layer On the first floor of the main building different internal wall insulations are applied. For this project, a reversible solution for energy retrofit is being developed (see image 3), transferring and using technologies from mural paintings conservation for the first time for the application of internal wall insulation. The focus of the project lies on thin, innovative systems, on mineral, capillary active insulations and on materials made from renewables like cattail (Typha). This area of the building will also have heating and an innovative climate control system, to obtain a certain moisture load during winter time that will allow us to assess risk from moisture in the historic building construction by monitoring. It will be possible to reach an indoor climate close to a museum climate in the Alte Schäfflerei and at the same time to assess the consequences this More contents on

14 has for a historic building in a climatic zone with harsh winters. At Benediktbeuern temperatures can drop as low as -20 C in winter time. High relative humidity indoors can lead to condensation on cold building elements. Especially wooden beams are susceptible to damages from high moisture caused by use of the buildings. At the main building almost all historic wooden beams had to be restored during the last major refurbishment in 2010 and Different, innovative and standard solutions were applied here that are now monitored closely. It is planned to open the building to the public in 2015 after 5 years of construction works that were accompanied by research projects. From 2015 on further research and demonstration activities are planned. This includes the restoration and preservation of historic windows, establishing a warm roof in the northern building by different options of attic insulation, innovative external wall insulation with aerogel plasters and other thin materials on one façade of the northern building, and more. Regular exhibitions and guided tours will take place on site. 3. Training of energy consultants for HISTORIC buildings In heritage buildings it is not easy to find the best fitting solutions for energy retrofit, because often measures for improving energy efficiency will change the appearance of the building and can have quite a severe impact on the historical building fabric, building surfaces or even on its construction. Especially questions of durability, reversibility and prevention of damages related to energy retrofit measures have to be addressed. All historic buildings have certain individual characteristics and specific heritage values, which have to be taken into account when planning restoration measures of any kind. Also general energy retrofit target as they are defined for nonlisted buildings cannot be applied here. Therefore the aim of the heritage authorities and other relevant institutions in Germany was to establish a specialized training course for Energy Consultants for Historic Buildings. This new training for experts should help to establish a high quality of monument preservation in the area of energy retrofit. The guidelines for the training of energy consultants for historic buildings [1] were developed and published by a large consortium of German institutions. Involved were the Bayerische Ingenieurekammer-Bau, Arbeitskreis Denkmalpflege und Bauen im Bestand, the Deutsche Bundesstiftung Umwelt (DBU), the Deutsches Nationalkomitee für Denkmalschutz (DNK), the Fraunhofer-Institut für Bauphysik IBP, Zentrum für energetische Altbausanierung und Denkmalpflege, Benediktbeuern, the Vereinigung der Landesdenkmalpfleger in der Bundesrepublik Deutschland (VdL), the Wissenschaftlich-Technische Arbeitsgemeinschaft für Bauwerkserhaltung und Denkmalpflege e. V., Regionalgruppe Deutschland (WTA-D), the Architektenkammer Hessen and the Zentralverband des Handwerks. This way all the relevant professions, trades and institutions architects, engineers, craftsmen, heritage authorities and building researchers that are involved in the restoration of an historic building as well as in energy retrofit measures were brought together to develop the guidelines. The course gives an overview of all the relevant topics that have to be addressed when restoring a historic building. It consists of 72 teaching units à 45 minutes (see Table 2). One major part of the course is the introduction to special issues related to the preservation of listed and other valuable traditional buildings, like basics of monument preservation laws, basics of practical monument preservation, special ways and methods of refurbishment, building analysis from monument preservation point of view, historic building techniques and historic building styles as well as the characterization of especially valuable historic structures. Also possibilities for funding and laws and regulations are addressed. Another important focus lies on the correct assessment of historic structures from a building physics point of view. Here materials, building construction and technical systems of historic buildings are discussed, moisture management and moisture More contents on

15 prevention, air exchange and infiltration, building damages and their causes as well as implications of user needs and user behavior. The course is concluded by four large blocks on development of concepts that are in accordance with heritage preservation, the consideration of holistic approaches, specific planning and the application of refurbishment measures on site.

Today more than 850 Energy Consultants for Historic Buildings are listed in Germany in an online list ( The integration of these specialists for all relevant restoration works in historic buildings is strongly recommended by the State Heritage Authorities. This way, specialized counselling is now available for communities and heritage building owners REFERENCES Koordinierungsstelle Energieberater für Baudenkmale. (2014).
