    Transparent Facade Constructions: A Comparison between Conventional Insulation Glass and Vacuum Glazing

    No full text
    (no german version) In recent years, contemporary architectural design has been influenced by new technical opportunities offered by the glass industry. Large glass panels and even structurally active glass elements can be found in many recent building designs. Moreover, building envelopes in many cases include large glass panels. Needless to say, the use of glass as an envelope material comes with advantages and disadvantages, and a good architectural design has to consider these aspects. Advantages, amongst others, encompass the increased solar penetration and solar gains in the cold season, the increased daylight availability, and the "clean" appearance of buildings; Disadvantages include, amongst others, the overheating risk in summer, thermal discomfort as a result of radiant temperature asymmetries, and increased heat loss. The last two aspects are directly linked to the rather high heat flow through conventional glazing systems compared to well-insulated opaque building components. There are numerous examples of buildings, where prevailing performance problems can - in one way or the other - be linked to inadequate planning of the transparent building envelope. Generally speaking, the transparent parts of building envelopes can be distinguished in elements that are operable (windows, doors), and elements, which are fixed. The former are characterized by highly complex opening mechanisms and seals and thus rather high cost. The latter regularly are less complex, but their design needs to consider other aspects (durability, structural stability, etc.). This contribution illustrates the results of a number of numeric thermal bridge simulations focusing on transparent façade constructions with fixed glazing. Thereby, the key performance indicators of different construction scenarios are derived and compared. These indicators include thermal coupling coefficient, surface temperature, and condensation risk. The scenarios are based on typically applied transparent façade constructions, which are simulated with insulation glass and, alternatively, with vacuum glazing. As transparent constructions with fixed glazing regularly have higher life-time expectancies than openable windows (given the reduced complexity), such constructions might be promising in terms of vacuum glass application and a thus improved thermal building performance. Moreover, the reduced weight of vacuum glazing panels in comparison to highly-insulating double and triple glazing might allow for more efficient building construction (structural elements, etc). The present contribution illustrates the construction principle of different elements, the simulated scenarios, and the results of the simulation runs.In recent years, contemporary architectural design has been influenced by new technical opportunities offered by the glass industry.

    "Abschließend beschäftigt sich Ulrich Pont mit innovativen Technologien, die eingesetzt werden können, um den Gebäudebestand „klima t“ zu machen. Dabei steht der sensible Altbaubestand im Mittelpunkt, dessen Erhaltung als kulturelles Erbe für das Erscheinungsbild von Altstädten eine wichtige Rolle spielt. Allerdings besteht ein Zielkon ikt zwischen Bestandsschutz bzw. der Erhaltung des gebauten kulturellen Erbes und den Zielen der Energiee zienz. Pont stellt einige innovative Technologien vor, wie zum Beispiel die Optimierung von Kastenfenstern, die den Altbestand auf ein hohes Level energetischer Performance entsprechend den heutigen Erfordernissen der Nutzer:innen bringen.

    Performance Enquiries Regarding Traditional and Contemporary Indonesian Architecture: A Holistic Approach

    No full text
    (no german version) This contribution sheds light on recent research efforts that pertain to the built environment in Indonesia. Within the rich diversity of cultures in the Nusantara archipelago interesting examples can be found that illustrate the adaptation to the challenging environmental conditions. Through this research the possibilities for sophisticated solutions for future are investigated, focusing on the building performance. Architecture and planning tasks in Indonesia have to consider the following preconditions: (i) The prevailing hot and humid climate, which will be strongly influenced by the climate change in the future; (ii) the country´s geography, which consists of a number of wide-spread islands; (iii) the rich and diverse historical development, including a very diverse architectural heritage; (iv) the location within the "Pacific Ring of Fire", causing recurring natural disasters (e.g. volcano eruptions, earthquakes); (v) a currently ongoing rapid change in socioeconomic key data (economic growth rate, population growth, digitalization); (vi) a strong tendency to urbanization. Whereas these facts are known, as well as the need for energy efficient buildings, the level of knowledge about the performance of buildings in different regions of Indonesia is rather limited. Specifically, regional building traditions are often treated only in historical discourse. Thus, an interdisciplinary research effort that aims to examine Indonesian architecture in a comprehensive and holistic way has been undertaken in the past years, based on works dating back to 2005. In this paper we present parts of these efforts, namely (i) the assessment of a contemporary art museum in the city of Yogyakarta using monitored indoor conditions, and conception of potential future improvement; (ii) Further data collection efforts currently performed on a number of traditional residential buildings, (iii) a review of current, exemplary re-development efforts including the utilization and adaptation of traditional architectural concepts in Indonesia, and (iv) the details of the recently started incentive on interdisciplinary research on Indonesian architecture.This contribution sheds light on recent research efforts that pertain to the built environment in Indonesia.

    The Potential of Descriptive Building Specifications as an Alternative to Detailed Normative Calculations

    No full text
    (no german version) Energy performance calculations are stipulated by law in most European countries. Thereby, different calculation schemes have been developed in the past years in different countries. The physical processes in buildings were simplified in terms of normative calculation routines in most of these schemes. A major idea behind these simplifications was to enable different stakeholders (practitioners, engineers, and architects) to issue energy certificates without being simulation experts. Moreover, the simplifications needed to be described thoroughly in corresponding guidelines to ensure and facilitate the comparability of the energy performance of different buildings. However, neither of these objectives can be considered to be fully met. Regarding the former, the normative calculation procedures increased in complexity in the past years, so that the issuing of energy certificates requires not only the stakeholder´s expertise but also a comprehensive knowledge of the standards that form the calculation method. Regarding the latter, recent research efforts revealed that many guidelines do not fully cover every aspect of the calculation procedures and the assumptions regarding required input data. Thus, the comparability of energy certificates has to be strongly questioned, as a number of relevant calculation parameters are dependent on the interpretation of the corresponding issuer.Given this background, alternative approaches to building performance evaluation would be of interest. Previous approaches by different researchers suggested so called prescriptive indicators, which can be derived by basic building data (for instance, geometry and thermal quality of the building envelope components). This contribution is based on this concept. In the framework of a master thesis, a number of prescriptive indicators were considered. These indicators were derived for a set of sample buildings. In a parallel effort, energy certificates (encompassing Key Performance Indicators KPIs) were calculated for the sample buildings. It is clear that the prescriptive indicators cannot act as a 1:1 replacement for KPIs in terms of a numeric value. However, their usefulness can be expressed by the relation of the prescriptive indicator and the corresponding KPIs of a building. Thus, the results of the described calculation efforts were ranked. Subsequently, the lists of buildings ranked by the different indicators were compared in order to identify prescriptive indicators, which result in the same or at least similar ranking as the normative key performance indicators. Within this contribution, the suggested prescriptive indicators, the sample buildings, and the results of the analysis are presented and discussed.Energy performance calculations are stipulated by law in most European countries.
