Climate-neutral cultural centre Brotfabrik with 200 kW PV system

Development of a climate-neutral energy refurbishment concept for the Brotfabrik socio-cultural centre in Bonn Beuel with the following components:

  • Energetic refurbishment of the building envelope to a kfW70 standard
  • 200 kW PV system with 200 kWh electricity storage tank
  • Water-to-water heat pump 100 kW for heating and cooling purposes
  • Rapeseed oil peak load boiler 30 kW
  • Heat accumulator with 50 m³ volume

Construction with renewable or recycled building materials. In the course of the energy-efficient refurbishment of the building sample, barrier-free access to all public spaces is to be created. In addition, a concept is to be implemented to retain and infiltrate as much rainwater as possible on the site in the future, so that the connection to the public sewage system is no longer needed, the groundwater is enriched locally and the sewage system is relieved.

Implementation is scheduled to take place between 2024 and 2028.

Climate-neutral existing laboratory building with H2 storage (2023/2024)

The aim of the work is to develop an energy concept with which the laboratory building can be supplied with renewable energy as self-sufficiently and climate-neutrally as possible all year round. There are already projects in operation for similar commercial buildings and at neighbourhood level. However, these have so far been new buildings. The aim of this work is to simulate the possibility of a climate-neutral energy supply for a single energy-autonomous analytical laboratory in an existing building that is about 100 years old and to make recommendations for implementation.

Climate Landscapes Network - City and Countryside in Flux" (KlimNet) project

For three years, the partners in the project "Network Climate Landscapes - City and Countryside in Flux" (KlimNet) have been collecting examples and developing measures on how cities can arm themselves against the consequences of climate change through more greenery. In doing so, they collected ideas from citizens and worked closely with municipalities, initiatives, schools and other committed people. The most important experiences from the project are compiled in this guide.

Project "Sustainable industrial estates: Recommendations for municipalities

In cities, the resource "area" is a coveted commodity: companies need space to do business, citizens are looking for recreational and residential space, and urban planning must take precautions against heavy rainfall events. In this context, commercial areas can play an important role. WILA Bonn, together with the Technical University of Darmstadt, the University of Osnabrück and the Global Nature Fund, has tested how sustainable design of existing commercial areas can succeed in three cities: Remscheid, Marl and Frankfurt am Main. This brochure summarises how the tested measures can also be implemented in other cities.

Impulse event "Architecture and Eifel building culture

AXT-Architects-Weidingen

In four lectures, planning offices that are well-known beyond the Eifel region presented their contributions to building culture in the Eifel region, which have won competitions and awards. The winners of the Rhineland-Palatinate State Prize for Architecture and Housing 2013, the Eifel Building Culture Prize 2013, the North Rhine-Westphalia Timber Construction Prize 2014, the German Timber Construction Prize 2007 and the Rhineland-Palatinate Timber Construction Prize 2006 gave presentations.

Study "Life cycle assessment of settlements" (2002 I diploma thesis)

Diploma thesis by Holger Wolpensinger at the Faculty of Architecture of the University of Karlsruhe (TH) in 2002
First examiner: Prof. Dr. Niklaus Kohler ifib - Institute for Industrial Construction Production

Brief description
A housing development design with 140 flats (see www.sdg21.eu/db/autofreie-solarsiedlung-nancystrasse) for 420 inhabitants is examined for the relevant environmental impacts and their reduction potentials using the indicators GWP 100 (Global Warming Potential in 100 years) and primary energy in the standard/best-case and worst-case variants.

sdg21 web database of sustainable settlements and neighbourhoods (since 2000)

The web database sdg21 documents 232 settlements and 49 neighbourhoods, as well as 45 exemplary buildings (Σ = 326) with a total of 71,980 realised dwellings, which, with the exception of a few historical projects, have been realised under sustainable objectives in Germany and other European countries since 1980. A further 43,000 housing units are currently being built in sustainable neighbourhoods or eco-settlements. 5,579 photos, 211 photo galleries and 156 film references illustrate the projects that fulfil sustainable criteria in their implementation. A news blog with 846 contributions, including 75 announcements on the Sustainable Development Goals (SDG) 2030 and 136 announcements on funding and competitions, complement the project database. In 2021 and 2022, there were a total of 100,000 counted views each.
