efnMOBILE Efficient Envelope

International student workshops

The workshop program „efnMOBILE - Emerging Envelopes“ 2013-2016 powered by Alcoa Foundation is a cooperation of the TU Delft in the Netherlands - Faculty of Architecture; Prof Dr. Ing Ulrich Knaack and Hochschule Ost Westfalen-Lippe (Germany) Detmolder Schule für Architektur und Innenarchitektur; Prof. Dr. Ing. Uta Pottgiesser. The program will be a traveling workshop during the years 2013 till 2016 –  being active in several locations in Europe and provide the facility to experiment, build and evaluate building envelope constructions.

Workshop program "efnMOBILE 2.0 Efficient Envelope" 2016-2017.

Workshop 2017 – Delft

Interacting with the facade

Interacting with the facade: Lessons from everyday life in office buildings

The workshop centred around the general topic of user interaction with the building envelope, focusing on selected aspects of façade design and operation from users’ perspective.  Commonly, architects and façade designers are present during design and construction stages of the façade development process, without mayor involvement during the operation phase.  Hence, they usually miss the chance to evaluate how their designs perform in reality, preventing the use of valuable feedback for future projects. 

Therefore, the efnMOBILE workshop sought to position students in the operation phase of building envelopes, learning from the daily experience of users from real office buildings from TU Delft campus.  Office buildings consider extra challenges compared to residential buildings, due to the higher technical complexity of façade systems and unclear user profiles, which results on a need for standardisation that not always matches users’ comfort and control needs.

The workshop was structured around the assessment of real office buildings, focusing on three key aspects to promote a discussion about the role of the building façade during the operation phase, and the identification of existing possibilities for user interaction: comfort, automation, and maintenance. The assessment took the form of a simplified post-occupancy evaluation of the buildings, based on surveys and interviews with users and managers, besides direct observation on-site.

In total, 9 students from the University of Applied Sciences Ostwestfalen-Lippe and Delft University of Technology participated in the workshop which was held at TU Delft from June 19th to 21st. The main deliverables were the assessment of 4 buildings within TU Delft campus, along with conceptual designs to improve the main identified problems of each case.

The workshop was coordinated by Alejandro Prieto (TU Delft) with the assistance of Tommaso Venturini (TU Delft).  Prof.dr. Philomena Bluyssen, Dr. Natalia Romero, Dr. Stella Boess, and Juan Azcarate participated as guest speakers, giving inspiring lectures on the key selected aspects in which the assessment was based.  The workshop was also supported by TU Delft’s Facility Management & Real Estate, facilitating the participation of building managers and unrestricted access to the selected cases.  The results of the workshop were presented and discussed in front of a committee of façade experts from the European Façade Network (efn).

Workshop 2017 - Antwerp

Textile Building Skin

(Smart) textile structures and façades have a long tradition in architecture due to their lightweight properties, geometrical flexibility and resource efficiency. With new developments by combination of different materials within textiles various requirements in the façade can be addressed more decentralized and individually to user needs and/or environmental impact.

The efnMOBILE workshop addressed this potential and aimed to develop new concepts for textile building skins or textile façade components. Therefore teaching, research and practice from different fields was brought together at the workshop to trigger new concepts to be investigated by architecture, façade design, engineering and textile design students.

In total 24 students from the Master of Integrated Architecture focusing on façade construction at University of Applied Sciences Ostwestfalen-Lippe and from Textile and Surface Design at Kunsthochschule Berlin Weißensee participated in the workshop which was held at University of Antwerp from May 10th to 13th. Supported by Paul Denz (Priedemann/Facade-Lab) and Agata Kycia (Kunsthochschule Berlin), also by tutors from University of Antwerp and PJC Consulting.

Based on the case study building Green Tower at the Schüco campus in Bielefeld, Germany, six student teams developed façade solutions focusing on four main topics: Sun-Shading, Energy Generation, Ventilation and Acoustics.

With the help of textile materials and special geometries the students developed several solutions working with upscaling, deformation and material integration. For example the usage of dielectric elastomer fibers for energy generation, deforming sun-shading sails according to the sun-angle and floor-height woven waffle bindings. The workshop therefore not only showed the potential of textile building skins but also the successful interdisciplinary collaboration of such different fields of studies and industry.

Workshop 2016 - Düsseldorf

Form Finding Fabrication

From September 20th to 23rd the European Facade Network (efn) in cooperation with the Detmold School of Architecture and Interior Architecture (HS OWL) and the TU Delft have hosted the workshop ‚Form Finding Fabrication‘ and the Symposium ‚Digital Methods‘ at the glasstec 2016 trade fair in Düsseldorf. 

Workshop and symposium have been the semester kick-off for Detmold’s new master students and have been led by Prof.i.V. Hans Sachs and Dipl.-Ing. David Lemberski. More than 80 students in the field of architecture (Master Integrated Architectural Design - MIAD) and interior architecture (Master Innenarchitektur-Raumkunst – MIAR) developed  a huge variety of digital and physical prototype wall and roof structures in an interdisciplinary and interactive design and modeling process. The focus of this experimental workshop has been on the interconnection of analogue and digital modeling and fabrication techniques by using 3D printers, two CNC laser cutters, a CNC wirebender and cutting plotters. Within this interdisciplinary setup our international and national ‚newcomer students’ interconnected greatly at an early stage of their studies and immediately learned to use and integrate innovative modeling and prototyping techniques in the design development process. 

The symposium „Digital Methods“ which took place on September 21st at the EFN trade booth, eight expert speakers from various universities and companies presented their strategies, concepts and methods of design and development processes in a digital context. The symposium had a focus on future strategies, techniques and (working- and development-) methods that emerge from the application and interconnection of various kinds of arising digital tools. All speakers had a focus on digital techniques and working methods while coming from different disciplines such as architectural design, urban planning or from innovative digital (industrial) production processes (Industrie 4.0). Hereby a great variety of possible applications of digital tools and methods, not only in an architectural context but also at the intersection to other product related disciplines has been presented.

Workshop and symposium have been supported by the ALCOA Foundation through the project „efnMOBILE.Efficient Envelopes“, by the glasstec fair and by internal grants of HS OWL. Special thanks to Susann Kreplin and her team for design and organisation of the fair booth.
