Among other things, Schellnhuber calls for "timely action to achieve the two-degree target, primarily by switching from fossil to renewable energy sources and replacing finite building materials with wood and renewable raw materials."
With the Sustainable Small House Building (BNK) quality seal, there is now a standard for detached and semi-detached houses that you can use, for example, to optimise the conditions for insurance and financing of your own home. At the first official award ceremony, our "Room for Healthy Ideas" was also awarded the top grade of 1.4.
The exhibition marking the halfway point of the IBA Heidelberg has opened: A rich accompanying programme attracted almost 1000 visitors from Thursday to Saturday, many of whom were visiting the exhibition venue, the Mark Twain Center in Heidelberg's Südstadt, for the first time.
The IBA SUMMIT, the biennial meeting of mayors, university rectors and urban planners from international "Knowledge Pearls" in Heidelberg, heralded the opening days of the IBA interim presentation on 26 April. Prof. Dr Eckart Würzner, Lord Mayor of the City of Heidelberg welcomed the guests from Stanford, Cambridge, Lund and Leuven with an introduction to the IBA: "The IBA Heidelberg is on an excellent path. It demonstrates how various strengths of our city can be interwoven. These include, for example, promoting education, developing environmentally friendly mobility, creating new living space and promoting climate-neutral urban development. The IBA has made a significant contribution to the sense of a new beginning in Heidelberg.
The vernissage of the exhibition took place at the Mark Twain Center on the evening of 27 April. Gunther Adler, State Secretary for Building, Housing and Urban Development in the Federal Ministry of the Interior spoke on the occasion about the "IBA" format from the federal government's point of view. According to Adler, the IBA is an important piece of German building culture that enjoys international renown and is worth every effort to pursue its claim to excellence. The IBA tradition encompasses many aspects: International relevance, next-practice projects, sustainable impact on the region and building culture standards. For the IBAs currently underway, it is sometimes difficult to fully meet these claims to excellence under the given framework conditions. "Nevertheless, we are seeing overwhelming results, which encourage us as a federal government to continue the quality offensive together - also within the framework of the IBA Heidelberg," the State Secretary emphasised. "We need the IBA to show us how we can find answers to relevant questions of current urban development using new and unusual methods and means - this is more urgent today than ever. The IBA's courage to experiment and to go beyond existing boundaries is important to address the quality of living, working and living in our cities in the future."
Jürgen Odszuck, First Mayor of the City of HeidelbergThe IBA's interim presentation provides an excellent overview of what it is doing in Heidelberg: it gives important new impulses on how we can further develop Heidelberg as the knowledge city of tomorrow. It promotes excellent building projects in our city. And it offers innovative approaches on how we can design processes more effectively and lead to even better results."
Michael Braum, Managing Director of the IBA Heidelberg, was pleased about the great response to the exhibition opening and welcomed the guests: "Innovation in the knowledge society uses its intellectual and creative resources. This changes the value system of the industrial society, in which diligence stood above creativity. Today, in the knowledge society, creativity may be more important than diligence. This also has implications for the city. Our cities will change more dynamically in the 21st century than they did in the course of industrialisation. This requires a new way of thinking in urban planning and architecture. The IBA would like to make a contribution to this, which can now be seen in this exhibition."
Carl Zillich, Curatorial Director of the IBA Heidelbergexplained the exhibition concept: "Before we present realised building projects for the knowledge city of tomorrow in 2022, we have focused at the halfway point on the actors, processes and ideas of the first five years. Together with the exhibition makers from 'Stiftung Freizeit', we have developed analogue and at the same time interactive forms of presentation. Thus, for different interests, individual glimpses behind the scenes of the IBA, the urban development of international science cities, but also Heidelberg institutions and initiatives are on offer. Numerous architectural models, pictures and plans have already aroused curiosity about the construction sites, which are now marked all over the city."
The opening days closed on Saturday, 28 April with a colourful programme, during which many young families in particular got an impression of the exhibition and the IBA projects.
The exhibition of the IBA interim presentation is now open until 8 July daily from Tuesdays to Sundays from 15.00 - 20.00, including public holidays.

Mission 2020 is a global campaign, blending radical collaboration and relentless optimism to put emissions on a downward path by 2020. When it comes to our climate, timing is everything, and we have a game-changing opportunity to make the big changes now. Let's not be late for this turning point, so future generations can live in a climate safe world.

There is a shortage of housing in Europe's conurbations; Germany alone lacks about 1.5 million residential units (WE). For this reason, the federal government has decided to build 400,000 WE annually. At the same time, the federal government's climate protection plan foresees a significant decrease in building emissions from 209 million to 67 million tonnes of CO2-equivalents by 2030, which would correspond to an emission reduction of 68 % since 1990. Other European countries have also committed to implementing far-reaching climate protection targets. Against this background, many of those involved in construction are increasingly relying on wood as a renewable building material, in addition to energy-efficient construction and the use of renewable energies.
The Construction cost study on large timber housing estates and quarters in Europe (short Wooden housing study), financed from funds of the funding programme FUTURE CONSTRUCTION of the Federal Ministry of Transport, Building and Urban Affairs (BMWSB) and based at the Rottenburg University of Applied Sciences (HFR), systematically researches and records those projects in timber and timber hybrid construction that have already been realised or are currently in planning. In the process, the construction costs of the buildings are analysed as well as the motives of the investors and clients to build with wood. Another goal is to show how timber construction methods can be further established in the segment of housing estates and urban districts in order to expand the range of large-volume housing projects with an environmentally and climate-friendly variant.
