With the portal https://energiewendedörfer.de the University of Kassel and the Georg-August-University Göttingen present first results from the joint project "Innovative concepts and business models for sustainable bioenergy villages - climate-friendly, democratic, close to the citizens". In particular, concepts for bioenergy or biogas plants are being developed that can enable continued economic operation following the previous 20-year EEG phase.

With recommendations for action in the areas of residual material use, alternative energy crops, optimisation of value creation through recycling management, future electricity marketing, efficient heating networks and sector coupling of bioenergy with other renewable energies, bioenergy villages and operators of energy plants are shown possible new business models. To this end, the researchers are working in so-called real laboratories with the bioenergy villages Krebeck/Wollbrandshausen and Altenmellrich/Anröchte in order to be able to examine the feasibility and economic viability of the new models under practical conditions.

The platform https://energiewendedörfer.de offers recommendations for action as well as information on biomass and residual material potentials and a GIS map that presents the bioenergy villages in Germany and their measures and technologies. Among other things, this enables a targeted search for the fuels or substrates used and the technologies applied. It is aimed at all interested parties who are committed to an energy and heat transition in their villages or communities.

The CO2-In addition, attractive funding programmes and the Building Energy Act support local authorities in switching to a renewable heat supply. Extensive information offers on energiewendedörfer.de as well as the guides, market overviews and other service offers of the Agency for Renewable Resources (Fachagentur Nachwachsende Rohstoffe e. V. - FNR) provide the necessary information. (FNR) provide the necessary support to advance the energy transition in municipalities.

The joint project "Innovative concepts and business models for sustainable bioenergy villages - climate-friendly, democratic, close to the people" is funded by the Federal Ministry of Food and Agriculture (BMEL) via the project management organisation FNR. Information on the project is available at https://energiewendedörfer.de and in the FNR project database at www.fnr.de under the funding codes "22405817" and "22405218" available.

Guidelines for the design of our living spaces: Code of Building Culture published

© penofoto.com - stock.adobe.com

Building culture is becoming a recognised goal in the real estate industry: with support from the real estate and housing industry, the Institute for Corporate Governance in the German Real Estate Industry (ICG) and the Federal Foundation for Building Culture initiated and developed the Code for building culturea voluntary commitment for the responsible performance of tasks by companies in the real estate industry.

In its role as project developer, planner, builder, owner, etc., the real estate industry bears particular responsibility for the design of our living spaces. At the same time, building culture values and social acceptance form the basis for economic success. The Codex for Building Culture now supports companies in the real estate industry in assuming social responsibility for the consequences of real estate business activities and for the built results on their own initiative and within the framework of self-regulation. The fact that building culture offers added value for the real estate industry has now entered people's minds - but is not always put into practice. In the survey of the participation process for the code, for example, 98% of the companies surveyed stated that the appreciation of historic properties is seen as relevant or at least relevant to a certain extent - only half of the respondents, however, stringently implement this in practice.

Building culture is always closely linked to process quality, which is why the initiators of the Code for Building Culture were keen to involve the players in the real estate industry in the drafting process. Since a personal discussion of the contents was not possible due to the Corona pandemic, companies in the real estate and housing industry were asked in the summer of 2020 to provide feedback on the draft of the Code for Building Culture by means of an online survey and were thus involved. Scientific support was provided by IREBS at the University of Regensburg.

Prof. Dr. Sven Bienert, Chairman of the Institute for Corporate Governance in the German Real Estate Industry /IREBS Institute at the University of Regensburg, is in favour of this code because: "In times of rising land prices and ever higher building densities, the issue of a "good building culture" is becoming increasingly important. This form of social responsibility will also increasingly concern the real estate industry in the future in the ever more important after-use and conversion - for example of churches that are increasingly coming onto the market."

"Our goal is to make the real estate industry fit for the future," says Karin Barthelmes-Wehr, Managing Director of the ICG. "This includes encouraging the players in the industry to deal with all the requirements of ESG (Environment Social Governance) and to forge new alliances in this regard. For this, the Code for Building Culture we have presented provides a very good basis in the field of planning, development and construction."

Reiner Nagel, Chairman of the Board of the Federal Foundation for Building Culture, emphasises: "The Code for Building Culture now focuses on the responsibility of real estate business activities for the spatial impact of the built environment on us and the resulting consequences, with which companies grow in their building culture competence. As a result, the quality of the built environment benefits from the Code for Building Culture that is now available."

The complete "Code forBuildingCulture" and documentation of the participation process can be found at on our website. It contains the following demands (abbreviated).

Attitude and Values:
- Holistic building culture
- Prudent action in new construction and portfolio development
- Appreciation of already existing building culture

Visions and goals:
- Use stocks
- go easy on resources
- Promoting diversity and mix

Processes and Means:
- life cycle assessment
- quality assurance
- Cooperative collaboration

Supporters of the Codex for Building Culture already include:

City of Cologne reintroduces municipal right of first refusal

City of Cologne reintroduces municipal right of first refusal

Housing to be created through more effective development of building sites

The City of Cologne has revoked its waiver of the exercise of the municipal right of first refusal with effect from 1 February 2018 and announced it in the Official Gazette of the City of Cologne. At the same time, the City of Cologne informed the Cologne Land Registry, the Cologne Chamber of Notaries and the Federal Chamber of Notaries of the revocation of its general waiver. The City of Cologne has thus cleared the way for an important legal instrument to secure its urban planning. The aim of the municipal right of first refusal is the more effective development of building areas, which in particular serves the creation of affordable housing in the still tight housing market in Cologne.

The right of first refusal is available to the city according to the legal requirements, for example, for the purchase of land

  • in the area of application of a development plan, insofar as it concerns areas for which a use for public purposes has been determined in accordance with the development plan,
  • in a reallocation area,
  • in a formally designated redevelopment area,
  • in the area of application of a land use plan, insofar as it concerns undeveloped areas in the outer area, for which a use as residential building land or residential area is shown according to the land use plan, or
  • in planned or unplanned areas that can be built on primarily with residential buildings, insofar as the properties are undeveloped.

The City of Cologne can thus designate by statute areas in which it has a right of first refusal in areas where it is considering urban development measures in order to ensure orderly urban development.

Insofar as the legal requirements for exercising the municipal right of first refusal are not met or the city does not intend to exercise its right of first refusal, it will issue corresponding certificates to the parties involved. Fees ranging from 61.69 euros to 89.11 euros will be charged for this. The contracting parties or notaries are now required to submit purchase agreements on real estate transactions in the Cologne city area to the responsible Office for Real Estate, Cadastre and Surveying for examination of the right of first refusal. The City of Cologne has a period of two months from the submission of complete documents in which to check the existence of the pre-emptive right and to execute its possible exercise.

On 18 May 2017, the Council of the City of Cologne decided by a majority to reintroduce the right of first refusal after the city had waived it since 1995.

New solar roof register in Bonn goes online today

New solar roof register in Bonn goes online today

Roofscape with solar panels

BN - Is the roof of my house or company building suitable for a photovoltaic system or a solar thermal system? This question can now be answered quickly and conveniently online with the help of the new solar roof cadastre of the city of Bonn. In a building-specific map display, a coloured marker indicates whether and to what extent a roof is suitable for energy generation by means of solar power. Step by step, further information, for example on the economic efficiency, can be retrieved via a yield calculator.

The suitability of the roofs of all 129,000 buildings in the city for solar energy generation was recalculated using the latest, improved data. For this purpose, elevation grid data was used, which was determined by the district government of Cologne by means of laser scanning in spring 2016. Compared to the previous version from 2010, the new Bonn solar roof cadastre features, among other things, a fourfold higher resolution and a more differentiated designation of the roof areas.

The suitability of the roof surfaces for electricity generation via photovoltaic systems as well as for domestic water heating and, for the first time, also for supporting building heating via solar thermal collectors was calculated. The calculations also took into account the current changes in the framework conditions with regard to feed-in tariffs and self-consumption of generated solar power.

How the application works

In the city map, the installable system size and many additional data such as yields and savings potentials can be displayed for each building. In a newly developed yield calculator, costs and yields can be calculated and compared by entering additional user-specific information such as electricity consumption or household size. In this way, every owner can quickly gain an overview of the suitability of his or her building for the use of solar energy. Detailed instructions are available at www.bonn.de/...solardachkataster.php.

The City of Bonn points out that the information from the solar roof cadastre is an initial non-binding assessment. Essential prerequisites for a decision to build a system, such as the condition of the roof or the static suitability, can only be clarified by suitable specialist companies or qualified consulting organisations. Information on this can be found on the website of the solar roof register.

Bonn roofs have potential

According to the potential analysis of the solar roof cadastre, 6,800,000 square metres in Bonn are suitable for solar power generation. This corresponds to about the size of 950 football fields. Approximately 800,000 megawatt hours of electricity could be generated on this area. This could cover about 50 percent of the total electricity consumption in Bonn. For solar thermal energy, the result of the potential analysis shows 88,461 buildings in Bonn that could be used for this form of energy generation. This corresponds to about 70 percent of the buildings in Bonn.
