FAÇADE2014

The energy consumption needed to operate buildings can be significantly reduced with energy efficient building envelopes. Today’s facades are mostly passive systems and are largely exhausted from an energetic point of view.

They can neither adapt to changing environmental conditions related to daily and annual cycles nor to changing user requirements.

On the path toward more energy efficient buildings, multifunctional, adaptive and dynamic facades can be considered the next big milestone in facade technology.

PREFACE

Adaptive building envelopes are able to interact with the environment and the user by reacting to external influences and adapting their behaviour and functionality accordingly: the building envelope insulates only when necessary, it produces energy when possible, it shades or ventilates when the indoor comfort so demands.

In spite of numerous already realised projects the development and realisation of adaptive building envelopes is

still in the initial stage. In addition to new technologies

able testing methods must be developed, and existing

that enable adaptive behaviour, simulation tools and suitnorms and regulations must be adapted. Another step is to integrate such facades in the overall building system which requires a holistic view due to the many interfaces with other subcontracts such as building services, for example.

Currently, European research in the field of adaptive building envelopes is coined by numerous nationally funded projects and a lack of knowledge transfer between the individual research institutes amongst each other and the industry. To counteract this situation, the European Facade Network (EFN) with its partner universities TU Delft, University Ostwestfalen-Lippe (Detmold), University of Bath, University of the Basque Country and the Lucerne School of Engineering and Architecture has initiated COST Action TU1403M – Adaptive Facades Network.

FAÇADE2014

The main aim of the Action with more than 22 participating European countries is to harmonise, share and disseminate technological knowledge on adaptive facades at a European level and to generate ideas for new innovative technologies and solutions. This shall lead to: 1 increased knowledge sharing between the various European research centres and between these centres and the industry; 2 the development of novel concepts and technologies and/or new combinations of existing technologies for adaptive facades; 3 the development of new knowledge such as effective evaluation tools / methods for adaptive facades; 4 the start of new collaborations and research projects in the area of adaptive facades technologies.

COST Action was kicked off at the end of October 2014; planned to run for a period of four years. The target audience of the Action are researchers, manufacturers, the facade industry, professional associations, practicing engineers and architects, educational and standards bodies.

In parallel with this conference, a one-week workshop was held together with master and bachelor students from our partner universities of the EFN (TU Delft (NL), University Ost-Westfalen-Lippe in Detmold (D), Universidad del Pais Vasco (E), University of Bath (UK). This year’s challenge was to build a small prototype of an adaptive façade including an intelligent control system.

I would like to thank our organising partner and sponsors Swiss MetalUnion (SMU), JANSEN Building System, Wicona Hydro Building Systems AG, Sika Schweiz AG and Glas Trösch Holding AG for their generous donation of staff time, materials and/or funding. Thanks also to the partners of the European Facade Network.

My very special thanks go to Mr. Ueli Zihlmann, scientific assistant of the Competence Center Facade and Metal Engineering (CCFM) at the Lucerne School of Engineering and Architecture, for the professional organisation of the third edition of the conference FAÇADE 2014 – Adaptive Building Envelopes.
