Annual exhibition 2021

Faculty of Architecture

Due to the ongoing Corona pandemic, the JAA is appearing in a new format this year: the exhibition is spread throughout Aachen's urban space this year, with the main exhibition venue in the Stadtsaal. Both teaching work and students' everyday lives have changed fundamentally in the wake of the pandemic. Like all areas of life, architecture is also undergoing a change towards greater digitalisation and new challenges are arising. With this year's theme of perspective, we make use of the ambiguity of the term by reflecting on diverse spatial perspectives, points of view and future prospects in the architecture faculty at RWTH Aachen University. The exhibition will open on 6.10.2021 at 17:00 in the Stadtsaal.

Online PowerSKIN Conference 2021 - Simplicity vs. Performance?

The biennial PowerSKIN conference addresses the gap between science and practice and between the different disciplines of architects, engineers and scientists.

The conference addresses the role of the building envelope in achieving a carbon-neutral building stock. The focus of the 2021 edition, "Simplicity vs. Performance?", addressed the question of whether simplicity and robustness are at odds with good building envelope performance or whether they are even complementary.

The contributions presented current scientific research results and developments as well as projects on the topic of building envelopes from the perspectives of materials, technology and design. The contribution of Recycled Building focuses on the digital design fabrication of earthen projects and presents the state of research on this topic. The related technical article was written with TU Berlin, TU Braunschweig and TU Darmstadt and is published in the Facades Journal of TU Delft.

The conference was very inspiring and contained stimulating impulses. We are already looking forward to the 4th edition in 2023!

Conference contribution at 'Crossing Boundaries'

The conference "CROSSING BOUNDARIES, Towards a circular, sustainable and vital built environment" aims to create a platform where knowledge on the topic of 'circular and energy efficient building' can be exchanged on a scientific level to investigate the environmental and economic impact and share experiences on the latest developments in circular building.

The Parkstad region in the south of the Netherlands is facing a steady population decline and therefore has a large housing surplus, making it an interesting test area for the practice of circular building.

In keeping with these developments, the goal of this conference is to take the next step in enabling the circular economy in the built environment. The goal is to hold a scientific conference on circular economy in the built environment. The conference will result in the publication of a selection of the best papers and aims to provide guidance for a circular built environment.

The conference is a collaboration between Zuyd University of Applied Sciences, IBA Parkstad and the City Region of Parkstad organization.

Kim Tran presents a scientific paper from the institute.

The recordings of the conference sessions can be found online.

Keynote speech CRAVEzero

23 June 2020 (online workshop)

Alina Kretschmer will give the keynote speech at the end of the CRAVEzero funding project, in which the results on climate-friendly and cost-optimised almost zero-energy buildings will be presented in a practical way for municipal representatives. The lecture "circular and resource-efficient building" will provide impulses for a paradigm shift in the construction sector.

The research project CRAVEzero deals with the challenge of minimum energy consumption and cost optimisation of buildings on a municipal level. The knowledge gained is intended to support municipalities in creating affordable housing with the lowest possible energy consumption. The participants will gain insight into which measures can influence resource consumption in the individual planning and construction phases and how municipalities can keep cost control. In addition, the topics of energy efficiency in neighbourhood planning and the design of flexible living are involved.

Kick off event

Resource-efficient and recyclable construction in the Rhenish mining district

Postponed on the 22.06.2020 in Düren

As part of the launch event of ReNeReb and ReBau, we invite you to play an active role in shaping the future development of the Rhenish mining area with a focus on the construction industry.

The two projects bring together partners for resource efficiency and recycling-friendly construction in the region. One project goal is the initiation of a competence centre (within the framework of ReBau) in which various activities come together, such as the creation of databases (within the framework of ReNeReb). In this way, measures that have already been implemented and that make sense will become more visible and future steps will be further developed in the right direction. Together with you, the Rhenish mining district will thus become a nationwide pilot region for the resource turnaround in construction.

Harry Lehmann (UBA) will provide an impulse on the relevance of resource conservation and closed-loop construction as an integral part of any climate protection strategy and will rank various activities according to their urgency.

The event is aimed at political representatives, construction professionals, and interested parties.

The event is free of charge. Please send a registration form to info@aachenbuildingexperts.de
by 1 March 2020 is required.
