Lectures and conferences


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.

Real Estate Day 2020

30 March in Düsseldorf

Prof. Dr. Linda Hildebrand will give a lecture at 15:00 on "resource-efficient and recyclable construction". Klaus Dosch, head of the Faktor X agency, will then speak about "Ecological building - house building of the future".

The BFW North Rhine-Westphalia organizes the annual Real Estate Day, where the real estate industry, politics, administration and science come together to discuss the megatrends in the industry and to network further.

Keynote speakers include Dr. Jan Heinisch, State Secretary in the Ministry of Homeland, Municipalities, Construction and Equality of the State of North Rhine-Westphalia, Prof. Dr. Dr. h.c. mult. Hans-Werner Sinn, economist and finance scientist, and Prof. Dr. Günther Schuh, engineer and chair of production systematics at RWTH Aachen University.


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.

Future Building Congress 2019 - Building in transition

December 3rd and 4th 2019 World Conference Center Bonn

The best way to predict the future is to invent it. (Alan Kay)

Prof. Linda Hildebrand und Prof. Sigrid Brell-Cokcan are speaking on the 3rd december at the congress in Bonn, organised by the Federal Ministry of the Interior, Building and Home Affairs (BMI) and the Federal Institute for Research on Building, Urban Affairs and Spatial Development (BBSR). During the Zukunft Bau Congress 2019, possibilities will be discussed for shaping the future differently.

Topics include building in climate change, circular building and sustainable use of resources, innovative construction methods, new constructions and materials, digital methods of planning and manufacturing, and building culture as a common theme for existing and new buildings. Further lecturers include architects, civil engineers and researchers who present innovative solutions and suitable strategies, discussing with participants of the building sector and present guests.

Registration until 15th november. Participation is free of charge!

Drive 0 - Symposium on circular renovation

24.10.2019 Brightlands Chamelot Campus

Alina Kretschmer will speak at the symposium about the status quo and perspectives of recycling-friendly construction in Germany.

The symposium is the kick-off event of the Drive 0 project, funded by the EU Horizon 2020, which is to investigate efficient renovation solutions with regard to energy, materials and costs within innovative, consumer-oriented circular renovation processes. The aim is the transition from a linear economy to a circular economy.

As refurbishments play a key role in the decarbonisation of our existing buildings, they must be attractive, environmentally friendly and cost-effective for consumers and investors.

Huygen Installatie Adviseurs, together with project partners ZUYD and Brightlands Chemelot Campus, will launch the Drive 0 Symposium at the Center Court Building on Thursday, October 24, 2019. The symposium will focus on the principles of recycling-friendly refurbishment, the market perspective and circular business models.


Conference on May 8 in Berlin

re!source Stiftung

Klaus Dosch talks about the legal conditions of the circular built environment and his work at Factor X Agency. Further trend-setting and current topics from politics, science, economy and law are the focus of the conference "Resource Change in the Construction Industry" 8 May 2019 in Berlin. Further information and the programme of the event.


*** Zirkuläre Wertschöpfung im Bauwesen ***

Kompetenznetzwerk Umweltwirtschaft.NRW

The consumption of resources in building construction represents a weak point in sustainable construction. Possible solutions: Serial construction or improved controlling, with which architects, planners, authorities, building owners and operators can evaluate and optimise the use of materials throughout the entire life cycle.
Recycling management in construction: Is this an illusion or a pragmatic possibility for more sustainability in commercial and public construction?

Linda Hildebrand will talk about this aspects within the event "Sustainable and intelligent buildings", organized by the Competence Network Environmental Economy NRW (KNUW) on the 6th of December 2018

Location: IHK Dortmund, Märkische Straße 120, 44141 Dortmund, Germany

PLEASE REGISTER BY 30 NOVEMBER 2018 via www.knuw.nrw or by e-mail info@knuw.nrw
