Experimental Investigation of the Impact of PCM Containment on Indoor Temperature Variations

In view of growing concerns on climate change and temperature extremes, there is a need to explore novel methods that provide thermal comfort in architecture. Latent heat thermal energy storage with phase change materials (PCM) has been widely researched in last decades in the field of energy technology and proved beneficial for reduction and shifting of the thermal loads and improving the overall thermal storage capacity of building components. Although a variety of PCM containments have been investigated for indoor cooling applications, the examples of exposed, design-oriented macro-encapsulations are rare. This paper presents a study of visible, suspended ceiling encapsulations for passive cooling, made of glass and novel bio-based PCM. The aim is to provide an overview of correlations between basic containment geometries and their thermal behavior that serves as a base for the further design of custom-made PCM macro-encapsulations. An experimental set-up of test boxes is developed for thermal cycling and a comparative analysis of the thermal performance of varied PCM encapsulation geometries. The study concludes that the containments with the large exchange surface and the small thickness offer an optimal material distribution for the temperature reduction in the box. Based on experimental results, suggestions are made on further formal strategies for the design of cooling elements for local thermal regulation

Computational Design Modelling : Proceedings of the Design Modelling Symposium

This book publishes the peer-reviewed proceeding of the third Design Modeling Symposium Berlin . The conference constitutes a platform for dialogue on experimental practice and research within the field of computationally informed architectural design. More than 60 leading experts the computational processes within the field of computationally informed architectural design to develop a broader and less exotic building practice that bears more subtle but powerful traces of the complex tool set and approaches we have developed and studied over recent years. The outcome are new strategies for a reasonable and innovative implementation of digital potential in truly innovative and radical design guided by both responsibility towards processes and the consequences they initiate

Design-Based Research

Zugleich gedruckt erschienen im Universitätsverlag der TU Berlin unter der ISBN 978-3-7983-2652-1Heute sind die Entwurfsdisziplinen Landschaftsarchitektur und Architektur an den Universitäten aufgefordert, wissenschaftliche Forschung zu betreiben, die sich an den Forschungsformaten der Natur- oder Geisteswissenschaft orientieren sollen. Ist das sinnvoll? Ist das möglich? Wie ist das möglich? Welche eigenständigen Methoden können die Entwurfsdisziplinen anwenden? Kann es der Methode der Entwurfsbasierten Forschung gelingen, „individuelles Können” erfahrener Entwerfer mit „wissenschaftlich abgesichertem” Wissen zusammenzuführen? Führt dieser Brückenschlag zu einer besonderen Art des Entwurfswissens, das in stärkerer Weise durch Entwurfshaltung und Entwurfsprozess geprägt ist? Unter den drei Rubriken Entwerfen und Wissenschaft, Atmosphären entwerfen, Entwerfen und Konstruieren finden sich Antworten von Entwerfern und Theoretikern wie Wolfgang Jonas, Wolfgang Schäffner, Achim Hahn, Günther Vogt, André Kempe, Wolfgang Palz, Mike Schlaich, Volker Schmid und Jürgen Weidinger, die sich diesen Fragen aus individueller Perspektive nähern. Beiträge von Promovierenden und Nachwuchsentwerfern suchen und untersuchen Forschungsfragen, die neue Wechselwirkungen von Entwurf und Wissenschaft ausloten.Today design disciplines at universities like landscape architecture and architecture are asked to conduct research using methods which respond to research in the natural sciences and humanities. Is that reasonable? Is that possible? Which independent approach could design disciplines follow? Will the method of design-based research succeed in connecting “individual knowledge” of experienced designers to “scientifically verified knowledge”? Could this integral approach lead to a type of designerly knowledge that is influenced by the design process and the individual attitude of the designer? Under the three captions Design and Science, Designing Atmospheres, Design and Construction, initial answers are given from the individual perspectives of designers and researchers, architecture critics, well-known landscape architects and architects. PhD candidates and young designers investigate potential research questions that explore interactions between design and science. The authors manage an intense walk from theory to practice. Norbert Palz, for example, who teaches Experimental Design an University of Arts Berlin, describes how digitally contolled material properties support innovative architecture. Young researcher Guo Yong, inspired through analysing design theories, develops a design concept for an unautorized landfill near Beijing. Architect André Kempe from Dutch Atelier Kempe Thill explains, how building typologies promote architectural experimentation. Graphics and photos illustrate fields of research and applications
