Der Verbrauch von Heizenergie in Bestandsgebäuden stellt einen großen Anteil am gesamten nationalen Energieverbrauch dar und trägt deshalb maßgeblich zur Produktion von klimaschädlichem CO2 bei. Um den Klimawandel aufzuhalten und einen substanziellen Beitrag zum Klimaschutz zu leisten, muss deshalb der Heizenergieverbrauch dringend reduziert werden. Dies geschieht am effektivsten durch den Erhalt und die energetische Sanierung von ungedämmten Gebäuden. Wärmedämmung ist und bleibt eine der wichtigsten Maßnahmen zur Senkung des Energiebedarfs im Gebäudebereich. Dabei gewinnt die Innendämmung in den letzten Jahren immer mehr an Bedeutung. Dies liegt daran, dass ein nennenswerter Teil des Gebäudebestands, der leicht von außen gedämmt werden kann, bereits saniert ist. Der Anteil der verbleibenden Gebäude, bei denen aus verschiedenen Gründen nur eine Innendämmung möglich oder auch vorteilhafter ist, wird im Gegenzug immer größer. Die Fläche der Außenwände nimmt beim Gesamtgebäude und damit beim energetischen Optimierungspotenzial einen großen Anteil ein. Um einen optimalen Sanierungserfolg zu erzielen, erfolgt die Konzepterstellung auf Grundlage des vorgefundenen Zustandes des Bestandsgebäudes.:1 Einleitung 1 2 Planungsphasen 2 3 Fassadensanierungskonzept 5 3.1 Denkmalstatus 5 3.2 Dokumentation des Fassadenzustandes 5 3.3 Generelle Maßnahmen an der Bestandskonstruktion 6 3.4 Hinweise zum Schlagregen- / Spritzwasserschutz 10 3.5 Maßnahmen bei Putzfassaden 15 3.6 Maßnahmen für Sichtmauerwerk 16 4 Erstellung eines Dämmkonzeptes 19 4.1 Festlegung des gewünschten Dämmstandards 19 4.2 Auswahl möglicher Dämmsysteme 20 4.3 Überblick über die wichtigsten Bewertungskriterien 28 4.4 Hygrothermisches Verhalten typischer Dämmsysteme 28 5 Dimensionierung und Nachweis 29 5.1 Nachweisfreie bzw. als erfüllt erachtete Konstruktionen gemäß DIN 4108-3 30 5.2 Vereinfachter Nachweis für Innendämmungen 30 5.3 Erweiterung des vereinfachten Nachweises - Klassifizierung diffusionsoffener kapillaraktiver Dämmsysteme 31 5.4 Nachweis durch hygrothermische Simulation 34 5.5 Simulationstabellen für typische Anwendungsbereiche / Freigaben durch Hersteller 36 6 Dimensionierung / Ausführung von Anschlussdetails 37 6.1 Allgemeine Dimensionierungsempfehlungen 37 6.2 Typische Anschlussdetails 39 6.3 Auswahlkriterien für die Detailbemessung 40 6.4 Konstruktive Hinweise bei Innendämmmaßnahmen 43 6.5 Hygrothermische Simulation von Anschlussdetails 46 7 Literaturverzeichnis 47 A Anhang 49 A I Beschreibung von Abdichtungssystemen 49 A II Untersuchte Dämmsysteme zum hygrothermischen Verhalten (aus EnEffID) 53 A III Erstellung eines vereinfachten Nachweises nach WTA-Merkblatt 6-4 57 A IV Randbedingungen für den vereinfachten Nachweis zur Klassifizierung diffusionsoffener, kapillaraktiver Dämmmaterialien 58 A V Auswertung der Klassifizierung diffusionsoffener, kapillaraktiver Dämmmaterialien 59 A VI Kennwerte, Randbedingungen und Bewertungskriterien für hygrothermische Simulationen 60 A VII Anwendungsbeispiel für eine eindimensionale hygrothermische Bemessung 63 A VIII Anwendungsbeispiele für die hygrothermische Bemessung von Anschlussdetails 67 A IX Typische Anschlussdetails 74 A X Ablaufschema Fassadensanierungskonzept 101 A XI Ablaufschema Dämmkonzept 102

The subject of this diploma thesis is to continue on the previous atelier work, which was focused on elaboration of a strategic urban-architectural study of the Kraví hora area and the BUT holding located there. A multifunctional facility, which would include activities that BUT still lacks, should be designed there. In any case, it should not be an extension of the teaching, research or accommodation capacities, since there have been built enough of these by BUT recently. At the same time, the proposed activities should not be controversial with the interests of the city. The BUT area at Kraví hora is one of the most valuable areas of the city of Brno. The city, which has tried to buy it from BUT several times, has an eminent interest in this area. However BUT considers it as its "family silver", because they realize its extraordinary value. Nevertheless, due to the binding regulatory conditions, construction possibilities are very limited. The aim of this study is to find such a use of this area, which would be a compromise corresponding to both the city's expectations and the needs of BUT. The intention of the previous project, which has been continued by this diploma thesis, was the removal of unsatisfactory buildings and the reduction of the garden colonies; despite to a study created by the City of Brno but partially kept, cultivated and reorganized; and rebuilding of the BUT area, which will be opened to the public and communicate with park. The public will obtain an access to nowadays inaccessible and impermeable areas by removing inappropriate buildings and fences, as well as by the modification of the public space and creating one major spine communication realized as an extension of the existing road and which will serve only for the supply, hikers and cyclists. The newly founded BUT complex with its strategic location on the top of Kraví hora hill and next to the observatory will invite large number of people not only from the surroundings but a

Bestärkt durch das gesellschaftliche und wirtschaftliche Interesse an nachhaltigen und ressourcenschonenden Formen des Bauens gewinnen Holzkonstruktionen wieder unverkennbar an Bedeutung. Mit dieser Entwicklung bilden sich neue Konstruktionsprinzipien und Materialkombinationen im Bauwesen heraus, zu deren ingenieurtechnischer Beurteilung zum Teil keine ausreichenden Erkenntnisse vorliegen. Verbundkonstruktionen aus Holz und Glas sind eine innovative Bauweise, die zu einer höheren Materialeffizienz in Fassaden beiträgt, deren Wirkungsweise aber noch nicht ausreichend hinterfragt wurde. Werden Holz und Glas durch eine tragende Klebung verbunden, lässt sich das vielfach ungenutzte Tragpotenzial ausschöpfen, das eine in Scheibenebene belastete Verglasung aufweist. Die Qualität der Klebung entscheidet dabei über die Eigenschaften und das Leistungsvermögen des Bauteils. Die üblicherweise an dieser Schnittstelle eingesetzten Silikonklebstoffe weisen eine hohe Nachgiebigkeit und eine vergleichsweise geringe Festigkeit auf. Wenn die Verbundelemente als Aussteifung mitwirken sollen, bleibt ihr Einsatz deswegen auf Gebäude mit höchstens zwei Geschossen limitiert. Die vorliegende Arbeit trägt entscheidend zur Erweiterung der baulichen Möglichkeiten bei, indem sie der Anwendbarkeit von hochfesten Klebstoffen, die für den Einsatz im Bauwesen nur wenig erforscht sind, auf vielschichtige Weise nachgeht. Im Fokus stehen aussteifende Holz-Glas-Verbundelemente für die Fassade. Weder die Bauart noch das Bauprodukt Klebstoff sind derzeit in Deutschland in einer Norm erfasst. Das Klären der baurechtlichen Rahmenbedingungen ist daher unerlässlich und erfolgt mit engem Bezug zum konstruktiven Glasbau. Zusätzlich zur wissenschaftlichen Interpretation wird dadurch eine praxisnahe Bewertung der Versuchsergebnisse möglich, was ein Alleinstellungsmerkmal dieser Arbeit darstellt. Das Verformungsvermögen des Klebstoffs spielt eine zentrale Rolle bei der Materialauswahl und Gestaltung der Holz-Glas-Verbundelemente. Der Einfluss der Klebstoffsteifigkeit auf das Tragverhalten eines Einzelelements und auf dessen Interaktion mit den anderen Bestandteilen des Tragwerks wird an einem Modellgebäude untersucht. Auf Basis dieser Parameterstudie lassen sich drei Steifigkeitsbereiche definieren, auf die sich die Klebstoffauswahl für die weiteren Untersuchungen stützt. Der experimentelle Teil der Arbeit beginnt mit der ausführlichen Charakterisierung von sieben Klebstoffen. Davon werden zwei höherfeste Klebstoffe als geeignet identifiziert. Ein Silikonklebstoff wird als Referenzmaterial zur aktuellen Anwendungspraxis festgelegt. Das Hauptaugenmerk der folgenden Experimente richtet sich auf Aspekte der Alterungsbeständigkeit und des zeitabhängigen Materialverhaltens unter langandauernder mechanischer Beanspruchung. In labormaßstäblichen Alterungsprüfungen werden die Klebstoffproben unterschiedlichen Schadeinwirkungen ausgesetzt, die im Glas- und Fassadenbau relevant sind. Darüber hinaus erfolgen Kriechversuche an kleinen und großen Scherprüfkörpern. Letztere stellen einen besonderen Mehrwert dar, da sie eine realistische Klebfugengeometrie aufweisen und die Ergebnisse dadurch dem tatsächlichen Bauteilverhalten nahekommen. Für diese Zeitstandversuche wurde eine bislang einzigartige Versuchsanlage aus sechs Prüfrahmen mit Gasdruckfederbelastung entwickelt. Im Ergebnis zeigt sich, dass mit den gewählten höherfesten Klebstoffen die Festigkeit der nicht gealterten Klebschichten erwartungsgemäß gesteigert werden kann. Der Bruch des Fügepartners Holz wird zum maßgebenden Versagenskriterium. Die Verformungen des Verbundelements reduzieren sich gegenüber einer Silikonklebung deutlich. Allerdings offenbaren sich in einzelnen Alterungsszenarien und unter langandauernder Belastung auch Schwachstellen dieser Klebstoffe. Ihre Verwendung kann daher nur mit konstruktiven Kompensationsmaßnahmen oder durch Abschirmen der kritischen Einwirkungsgrößen empfohlen werden. Entsprechende Vorschläge werden bei der abschließenden Bewertung der Ergebnisse unterbreitet. Verfahren und Beurteilungsmethoden, die in dieser Arbeit angewendet und entwickelt werden, erleichtern die zukünftige Bewertung weiterer aussichtsreicher Klebstoffe für den Holz-Glas-Verbund. / Wooden constructions are on the rise again – encouraged by a strong public and economic trend towards sustainable and resource efficient buildings. Spurred by this growing interest novel design principles and material assemblies in architecture and the building industry evolve. These developments require further research due to the absence of evaluation tools and insufficient knowledge about their design. Load-bearing timber-glass composite elements could contribute to a more efficient use of materials in façade constructions. In this case a linear adhesive bond connects the glass pane to the timber substructure. This enables an in-plane loading of the glass whose capacity is not used to its full potential in conventional façades as it is solely applied as an infill panel. The quality of the adhesive bond defines the characteristics and the performance of the whole structural component. Structural sealants such as silicones, which are typically used for the joint, provide a high flexibility and only a low load-bearing capacity. Considering such elements being part of a bracing system, the mentioned characteristics limit the application range to buildings with not more than two stories. This thesis widens the scope with an in-depth examination of high-modulus adhesives, which have not yet been evaluated for their use in building constructions. Timber-glass composite elements used as a bracing component in façades are the focus of this work. Neither the full structural component nor the adhesive have yet been included into German building standards. Hence it is essential to assess the general requirements of their application. The relevant aspects are clarified in the context of glass constructions. In addition to the scientific discussion of the results, this approach facilitates also a practical evaluation of the findings, which is a unique feature of this work. The deformability of the adhesive becomes a crucial criterion when selecting the individual materials and designing the timber-glass composite elements. A case study assesses the influence of the adhesive stiffness on the behavior of a single element and its interaction with other members of the structural system. Based on the results, three different stiffness classes are introduced to support the selection process of the adhesives to be examined in further investigations. The experimental part of this work is initiated by a comprehensive characterization of seven shortlisted adhesives. The results enable a further differentiation of suitable materials. Two adhesives qualified as suitable for the main experiments. A silicone adhesive complements the test series to serve as a reference material to the current practice. In the next phase attention is drawn to the ageing stability and on the time-dependent material behavior of the adhesives under long-term loading. Small-scale specimens made from adhesively joint timber and glass pieces are exposed to different ageing scenarios which relate to the impacts typically encountered in façades. Beyond that, creep tests are carried out on small and large shear specimen. The latter provide extra benefit as they comprise long linear adhesive joints resembling virtually the situation in a real-size element. A specific long-term test rig was developed for this purpose comprising a loading unit with gas pressurized springs. Based on the results it can be concluded that joints with adhesives of high and intermediate stiffness enable an increase of characteristic failure loads and a significant reduction of deformation. With the stiffer joint near-surface rupture of timber fibers becomes the prevailing failure mechanism. The timber strength limits further loading of the adhesive joint. However, ageing and creep testing reveal also shortcomings of the adhesives. Their application can only be recommended if redundant compensation measures are taken or the joint is protected against critical environmental impacts. Appropriate solutions are proposed with the final recommendations of this work. Methods and assessment tools that have been developed and tested for this work offer the possibility of a more straight-forward evaluation of further promising adhesives and their use in load-bearing timber-glass composites.
