With more than 900 projects in over 40 countries, every project that Zaha Hadid Architects designs and builds has an impact on the narrative of contemporary architecture. At ArchDaily, we know that each architectural project has a team of professionals behind it which makes it possible. In this edition of the ArchDaily Professionals Video Interviews, we talked to Johannes Schafelner, associate director at Zaha Hadid Architects, and Enrique Peiniger, founder of OVI-Office for Visual Interaction about their long-standing collaboration in projects merging design and lighting.

Solar Decathlon Europe: Sustainable Lighting Combines Engineering and Design

The motto of the Solar Decathlon Europe 21/22 was to convert and expand rather than to demolish and reconstruct. Recycling windows, using biodegradable materials for luminaires and connecting light with sensors represented just some innovative examples of the international university-level student competition in Wuppertal, Germany. For the first time, the competition presented an award for sustainable architectural lighting. This was a question of quality as much as quantity, and that applies equally to daylight and artificial light.
The Professionals Involved in the Best Projects of 2021

Every year, ArchDaily's curatorial team publishes thousands of new architectural projects. From this experience, we know that no one builds alone and that these projects would not have been possible without the collaboration of many other professionals that are as much involved as the architects and designers themselves.
Lighting Design in Architecture: A Conversation with Hervé Descottes and Steven Holl
ArchDaily Professionals is an initiative that focuses on all of the collaborators involved in architecture and construction, who participated and are credited in the projects we have carefully curated and published. This project aims to recognize and highlight the best collaborators responsible for delivering the best architecture, by delivering valuable knowledge related to the different disciplines within our community. Today, we are launching a series of video interviews between architects and collaborating professionals, to learn more about their work and to understand the importance of these relationships to deliver high-quality architectural projects.
For this first interview, ArchDaily’s Managing Editor, Christele Harrouk, met with lighting design firm L’Observatoire International’s founder, Hervé Descottes, and American architect Steven Holl. In this moderated talk, we had the chance to speak to Hervé and Steven about their collaboration in three cultural projects in the United States: the Institute for Contemporary Art at VCU, the Winter Visual Arts Building, and Nancy and Rich Kinder Museum. In this conversation, we learned more about what lighting in architecture means to them, how space and light should be conceived and why a close collaboration between architects and lighting designers is crucial to architecture projects.
ArchDaily Professionals: Highlighting the Best Collaborators Involved in the Best Architecture

After over a decade curating the best architecture, at ArchDaily we know that no one builds alone. Shaping our built environment demands close collaborations and partnerships between architects, designers, and hundreds of other professionals committed to each project. This is why it is time to recognize and highlight the best collaborators responsible for delivering the best architecture, while we continue delivering valuable knowledge related to the different disciplines within our community.
