Konrad Fischer (architect)

from Wikipedia, the free encyclopedia

Konrad Fischer (born October 28, 1955 in Würzburg ; † October 22, 2018 in Lichtenfels ) was a German architect , monument conservator and author.

Life

Fischer grew up as the first of three children of the Franconian architect Herbert Fischer (1919–1979) and his wife from Transylvania , the Evangelical Lutheran church musician Eva Fischer, née Möckesch (1923–1999). In 1957, the family moved to Schwürbitz in Upper Franconia , where the father had his own architecture office with a focus on sacred buildings and monument preservation. After primary school, he attended the Meranier-Gymnasium Lichtenfels from 1966 to 1975 . After completing his military service, Fischer studied architecture at the Technical University of Munich from 1976 to 1981 - like his father decades before - and graduated with the academic degree Dipl.-Ing. from. From 1982 to 1984 he completed a scientific traineeship at the Bavarian State Office for Monument Preservation , among others with Tilmann Breuer , Sixtus Lampl and Gert Mader . In 1984 he became a member of the Bavarian Chamber of Architects and in 1987 he moved his residence and office to Hochstadt am Main in a historic mill building of the Cistercian monastery. In 1988 he married the teacher Petra Bothe. The couple had three daughters and one son.

Award-winning half-timbered house in Eggenbach for Fischer's successful renovation

In 1979, while still a student, he took over the office from his deceased father and since then has overseen more than 450 renovations of old buildings and monument repairs in East and West Germany. In 2006 he advised the actor Nicolas Cage on the purchase of Schloss Neidstein . In 1991 the Bavarian State Ministry of Food, Agriculture and Forestry awarded him the “Medal for Services to Culture and Tradition in the Country” for a half-timbered house renovation in Eggenbach , after the renovation object had already been awarded the Medal for the Protection of Monuments from the Bavarian State Ministry for Science and Art in 1990 was.

Since 1988, Fischer has been speaking at home and abroad as a speaker and seminar leader, particularly in the field of the renovation of historic solid and half-timbered buildings. He has also written a number of articles in this field for professional journals. From 1996 to 2006 he was an honorary chairman of the “Advisory Board for Monument Preservation” in the German Castle Association . In addition, he was a member of other associations, including the Federation of Nature Conservation in Bavaria , the Bavarian National Association for Homeland Care , the Franconian Federation , the Hennebergisch-Franconian History Association , the International Working Group for House Research (AHV), the Farmhouse Interest Group , the South Tyrolean Castle Institute and in the National Anti- EEG Movement / Electricity Consumer Protection (NAEB).

Fischer died in 2018 at the age of almost 63 after a brief, serious illness of cancer.

Controversy

From around 1996 Konrad Fischer made a name for himself as "Dämmketzer" or as "one of the most dazzling opponents of insulation in Germany" by taking many thermal insulation measures , in particular conventional thermal insulation composite systems on exterior facades, as "costly bad investments" and as "Klimbim of the insulation industry" condemned.

He essentially took over the theses of the architect Claus Meier , "with a more radiation-intensive heating, the room air temperature can be reduced significantly compared to the convection-optimized heating - the energy savings are therefore enormous" . Because the humidity of the indoor air (source: breathing, evaporation, drying, plants, etc.) should be removed from living spaces by air exchange , more energy would be lost with the air exchange with convection heating (in which the room air is heated) than with body or traveling warming Radiant heater. Thus (according to Fischer) heating systems based on thermal radiation, even with leaky windows, would be more efficient than those with convection heating and thermal insulation. Failure to change the air in the pleasantly warm air would often lead to condensation of moisture in the interior and as a result, in connection with organic nutrients (from binders, paint, wallpaper adhesives, paper wallpaper) to serious black mold pollution (moisture in external thermal insulation systems, on the other hand, is caused by capillary action or penetration into joints Condensation or other forms of precipitation ; see more detailed information on moisture # Moisture in building components ). With radiant heating, however (according to Fischer) the “building envelope surfaces” would always be warmer than the air due to the absorption of thermal radiation, the air would never be cooled below the dew point there , the interior plaster would not be wet and mold would not grow; With convection heating, the air would always be warmer than a wall, which means that the dew point could be undershot on one wall.

In order  to avoid the risk of liability , he recommended to planners to examine the profitability of every insulation measure by calculating the possible amortization of the insulation costs of a component including the costs of maintenance and disposal, based on a reasonable period of usually ten years. In the cases of undue hardship to be uncovered by such cost-benefit analyzes , which, in Fischer's opinion, occur more frequently than is commonly assumed, planners and builders should use the option of exemption from the requirements of the Energy Saving Ordinance and the Renewable Energy Heat Act .

In 2013, the journalist Roland Stimpel from the Deutsches Architektenblatt criticized the style of Fischer's lectures, in which there had been Holocaust comparisons, as "free of taste and piety".
