In zunehmendem Maße werden in Europa Dach- und Außenwandkonstruktionen aus Sandwichelementen mit metallischen Deckschichten und Dämmstoffkernen aus Polyurethan-Hartschaum oder Mineralwolle geplant und ausgeführt. Diese Konstruktionen sind im Bereich der metallenen Deckschichten absolut...

This study reports ventilation measurement and occupant questionnaire results from newly built 102 Finnish detached houses. The results show that ventilation units were used constantly and the fan speed setting was changed very seldom. There was as light tendency to use higher speed in the summer than in winter. Ventilation units provide...

If you are asked now about us fully enumerate those standards that we would have to consider if we wanted to start building a house tomorrow, no one would probably report - and this despite the fact attend this conference loud construction experts. Even the most self-conscious would we probably initially only...

Bei der Herstellung kleinster Strukturen, z.B. in der Produktion von Mikroprozessoren, oder im klinischen Bereich, z.B. in Operationssälen, können sich folgenschwere Probleme durch Verunreinigungen in der Luft ergeben. Unter diesen Verunreinigungen ist nicht nur Hausstaub zu verstehen, sondern eine Vielzahl...

Low-energy buildings up to the passive house level slowly become generally accepted also in Tschechien, which is naturally connected with suitable ventilation strategies. The contribution presents the most frequently used technical systems and discusses those properties and acceptance. The number of built very...

Die Thermografie ist ein hilfreiches Mittel bei der Sichtbarmachung von Leckagen an der Wind- und Luftdichtheitsebene. Jedoch sind einerseits nicht immer die theoretisch notwendigen physikalischen Randbedingungen vorhanden und andererseits ermöglicht der Bauablauf nicht immer die optimale Gebäudepräparation...

The test results of BlowerDoor test and thermographic inspection at a nursing home, an administration building and a sports-hall are presented. The nursing home was revised thermically. The external walls were provided with a compound insulation system. Nevertheless the expected energy savings effect did not arise...

The airtightness of buildings gains in importance ever more for the planning of buildings. The regulations for the securing of the energy-saving thermal protection demand beyond that a durably air-impermeable building envelope, in order to avoid unnecessary thermal losses and building damages. This has effects on...

The investigation of the QHA (quality community timber construction and development, registered association) compare and evaluate by the example of a built reference house the energetic and economic efficiency of current building services systems with dwelling ventilation. As basis serve gas condensing boiler...

Manufacturing and development processes in the electrical industry (microchips), the technology for smallest elements with high precision, the medical research and the food technology as well as operating theatres require laboratories and/or areas with particularly unsoiled air. The clean-room technology dedicates itself to the...
