Difu report: Major differences in sustainability in German municipalities

The new National Progress Report on the Implementation of the New Urban Agenda shows the state of sustainability in urban development in German municipalities. The report was prepared by the German Institute of Urban Affairs on behalf of the Federal Institute for Research on Building, Urban Affairs and Spatial Development (BBSR).

Fraunhofer ISE short study: Increased construction of large rooftop PV systems with small tilt angles

In a recently written short study, scientists from the Department of Energy System Analysis at the Fraunhofer Institute for Solar Energy Systems ISE prepared an evaluation of the Market Master Data Register (MaStR) and the EEG system master data for photovoltaics (PV). Important findings of the analyses were that with 38 percent of the newly installed capacity, the increase in capacity in Germany is increasingly taking place in the segment of rooftop systems larger than 100 kW, 22 percent of the newly built PV systems are erected in a west, east or east-west direction and 19 percent of these systems have tilt angles smaller than 20 degrees.

Use calamity wood constructively

"The raw material wood is precious. It is therefore important to use it responsibly and in a way that conserves resources," warns Peter Aicher, Chairman of Holzbau Deutschland. Even if wood is affected by environmental influences or the bark beetle, it does not represent an inferior raw material, but has almost identical properties to conventional construction timber. "If the so-called 'calamity wood' has the same structural quality in terms of load-bearing capacity as conventional sawn timber, it can be used without restrictions," explains Aicher. In addition, the wood retains its important function as a CO2 sink, regardless of external impairments.

DGNB study: No additional costs for sustainable construction

A new study from Denmark takes a look at the costs of sustainable building construction and shows that more sustainable does not automatically mean more expensive. On the contrary. The study by Buus Consult on behalf of the DGNB system partner from Denmark, the Green Building Council Denmark, now provides clarity. In the study, it takes a close look at 37 DGNB-certified buildings.

"A quarter of a century ago, Bernd Janes looked for like-minded comrades-in-arms and founded an ecologically oriented housing estate on the outskirts of Kohlhof. At first, the new neighbors were eyed critically by the surrounding community. No wonder, because the houses were built in wood, four families shared one house and the gardens were not separated from each other by fences, but merged seamlessly into each other."

Book review "Wohnquartier in Holz - Mustersiedlung in München" DBU Bauband 4

The ecological model settlement on a former barracks site in Munich sets new standards in timber construction. Various timber construction methods and building types up to seven storeys are being tested side by side in eight building projects with the aim of a final scientific evaluation. Timber frame, timber frame and timber hybrid construction methods are being used.

Berlin tenant power project with 500 kWp

Wohnungsbaugenossenschaft Neues Berlin and Berliner Stadtwerke have agreed on another joint tenant power project. Six solar power systems with an output of around 500 kilowatts are being built in the Mühlengrund housing estate in Hohenschönhausen. Tenants of more than 1,100 apartments will soon be able to benefit from green electricity from their own roofs.

Wuppertal Institute study presents key points for 1.5 degree target

Glaciers are melting, sea levels are rising, heat waves and heavy rainfall are increasing: The consequences of climate change are visible and tangible worldwide, and the window of opportunity to act is shrinking. In order to significantly limit the global effects of climate change, the emission of greenhouse gases on earth must be drastically reduced. The agreement reached by the international community in Paris in 2015 sets the goal of limiting global warming to well below 2 degrees Celsius, but preferably to 1.5 degrees Celsius. Now, the Wuppertal Institute presented a study with possible cornerstones that can help to achieve the 1.5 degree target by 2035. The study shows that a climate-neutral energy system by 2035 is very ambitious, but in principle feasible, provided that all possible strategies from today's perspective are bundled. This requires, above all, bringing forward and intensifying measures that are described in many studies as necessary to achieve greenhouse gas neutrality by 2050.

BBSR publication "Social Mix and Good Neighbourhoods in Newly Developed Neighbourhoods".

Cover: BBSR, 2020The Institute for Urban Planning and Social Research WEEBER+PARTNER (Stuttgart) examined 16 case studies and interviewed responsible persons in municipal, cooperative and private housing companies. The projects are characterized by a wide range of planning and construction approaches. According to the study, social diversity requires structural diversity: Rental, social and owner-occupied apartments of different sizes and with diverse layouts were created in the new housing quarters. They are socially mixed - even within buildings - with the respective proportions in the neighbourhood being derived from local requirements. The new quarters also offer space for communal forms of living, for example for older people and those in need of care. And they are characterised by an attractively designed and green residential environment. Concept awards promote the planning and implementation of such projects: Through them, plots of land are not allocated according to the highest price, but for the best concept.

BBSR publication on concept awards in neighbourhoods

Cover image: BBSR, BMIConceptual procedures are increasingly establishing themselves as a further instrument of municipal land policy for locations with development potential. Here, the property is not allocated according to the highest price, but according to the concept that promises the most sustainable approaches to the further development of the neighbourhood. In this way, the procedures offer municipalities approaches to solving two current and urgent problems: the need for high-quality urban development and affordable housing.

Climate change: Aquatic ecosystem research societies from around the world call for immediate action

Deutsche Wohnen's push to finance building refurbishments

Climate protection is important to over 80 percent of Germans - but this should not be reflected in higher rental costs. In order to increase the acceptance of energy-efficient renovations, Deutsche Wohnen has developed a model of how climate protection and social compatibility can come together. The "Concept for Socially Compatible Climate Protection in the Building Sector" aims to significantly increase the rate of refurbishment in existing buildings in order to achieve national climate protection targets. At the same time, an economic stimulus package worth billions is being initiated.

Bundestag passes new building energy law

On 18 June 2020, the German Bundestag passed the Building Energy Act (GEG) in its third reading. With this law, the federal government is combining the existing requirements of the Energy Saving Ordinance (EnEV), the Renewable Energies Heat Act (EEWärmeG) and the Energy Saving Act (EnEG). For the information programme Zukunft Altbau (Future of Old Buildings), which is supported by the Baden-Württemberg Ministry of the Environment, the specifications of the new law are not ambitious enough. To bring climate-friendly building and renovation nationwide on the way is not possible in the future. "The legislator has missed it to introduce more demanding standards," says Frank Hettler of Zukunft Altbau. "For a sustainable building stock in Germany, however, these are urgently needed to achieve the climate targets." The GEG will now be forwarded to the Bundesrat, which, however, does not require approval, and is expected to come into force by the end of the year.

State parliament wants compulsory solar energy in Bremen

The parliament of Bremen wants to oblige the use of solar energy on all new and existing buildings in Bremen and Bremerhaven. Whenever the roof surface is completely renewed, they are to be equipped with a solar system in the future. This is photovoltaics and, if necessary, also solar thermal energy. The Senate is currently examining the latter.

Up to 100,000 euros for facade greening in Hamburg

To ensure that significantly more houses in Hamburg are greened with plants on roofs and facades, the environmental authority is making €500,000 in funding available from 1 June. A maximum of € 100,000 and up to 40 % of the costs, applicants can receive in future in grants. Applications can be made from construction costs of €1,000. Funding will be provided for ground and wall-based greening of new and existing buildings, preparatory work, climbing aids, plants, planting measures, irrigation systems, completion maintenance and the ancillary costs for professional planning and supervision.

With building culture through the Corona crisis: planning and building industry proposes four-point plan

The Federal Chamber of Architects (BAK) and the Federal Foundation for Building Culture, on behalf of the planning and building industry, today presented their proposal for an "Innovation Programme for Building Culture" to politicians in Berlin.

Anne Katrin Bohle, State Secretary in the Federal Ministry of the Interior, for Construction and Home Affairs, accepted the four-point plan. In it, the authors suggest measures to overcome the Corona crisis that will have a sustainable economic and social impact.

"Climate neutrality in urban neighbourhoods" in the issue "Ökologisches Wirtschaften 3/2019".

Research has identified neighbourhoods as an important level of action for climate protection. For this reason, the BMBF, BMU and Federal Ministries of Construction and Transport have funded several research projects on sustainable neighbourhoods, which are now being processed. The consensus of the research projects presented and the funding bodies is that "it is important to economically research neighbourhood concepts for a climate-friendly heat and power supply as well as an environmentally friendly mobility offer" and "to sensibly link the individual elements in the sense of a functioning sector coupling.

The focus articles of the issue "Ökologisches Wirtschaften 3/2019" show on the one hand the potentials of the neighbourhood approach for the implementation of climate protection measures, but also present best practice examples and discuss the feasibility in practice.

KfW presents SDG mapping of its new commitments in 2019

  • Over EUR 28 billion for "climate protection measures": KfW is one of the most important supporters of the Paris climate goals
  • Promotional bank is a global pioneer with its standardised SDG mapping
  • Strong international interest in KfW SDG mapping

KfW is today publishing the results of the SDG mapping of new commitments throughout the Group in 2019. In order to clarify the individual contribution made by KfW's new commitments to achieving the UN Sustainable Development Goals, KfW has developed a standardised procedure: 1,500 indicators are used each year to determine to which SDGs KfW's new commitments can be assigned. This makes the contribution transparent at both group and business sector level.

Economists call for more public housing

The federal government can give new impetus to public housing construction in Germany in the short term and thus help to ease the acute housing shortage in many major cities. The key to this is three federally owned companies that provide flexible support to Länder and municipalities in the development of construction projects and the construction of new housing: First, a consulting company that provides planning capacity to cities and municipalities. Second, a land fund that provides financial and conceptual assistance to municipalities nationwide in acquiring building land and financing infrastructure. Third, an investment company that strengthens the equity of municipal housing companies through financial participation. This is shown by Prof. Dr. Sebastian Dullien, Scientific Director of the Macroeconomic Policy Institute (IMK) of the Hans Böckler Foundation and Prof. Dr. Tom Krebs of the University of Mannheim in a new concept for a federal initiative "Future Housing".

France focuses on timber construction and eco-neighborhoods

From 2022, all new public buildings must consist of at least 50 percent wood or other sustainable building material. For buildings with more than eight storeys, the supporting structure must even be made entirely of wood.

It was also decided that 90 ecological neighbourhoods and 100 urban farms should be created in Paris.

Launch of the Housing.2050 initiative

Climate protection has long been one of the most urgent topics for the housing industry. In order to achieve a climate-neutral building stock by 2050, the 24 founding companies of the Wohnen.2050 initiative met in Berlin on 28 January 2020 to found the association. The nationwide association was initiated by the Nassauische Heimstätte | Wohnstadt group of companies.

"Don't just talk about climate change, act" - under this motto, the Nassauische Heimstätte | Wohnstadt Group invited founding partners from all over Germany to found the Initiative Wohnen.2050 (IW2050) association. The overarching objective is a climate policy alliance, which, in addition to strategic cooperation and a technical and content-related comparison, primarily focuses on economic and financial concerns to achieve the targets.

A prize that the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) and the Federal Environment Agency (UBA) have been offering since today provides the appropriate topic for discussion: With the new "Federal Award for Environment and Building", which will be awarded for the first time in 2020, the initiators want to distinguish projects with exemplary character in terms of sustainability - not only in the classic areas of existing buildings and new buildings, but also in five other categories. All players in the building sector can apply. The deadline for entries is 15 April 2020.

Further promotion of timber construction in Munich

The Munich City Council's Committee for Urban Planning and Building Regulations has decided to promote the construction of new, contemporary timber construction projects. This year, the city council will develop another grant programme for construction using wood and other renewable raw materials.

The subsidy programme is suitable both for individual projects and for larger housing estates and neighbourhoods. The aim of the city administration is to ensure that around 50 percent of the buildings on municipal land are constructed using timber.

The heat turnaround begins in the district

One of the Herculean tasks to achieve the climate targets is to radically reduce CO2 emissions from the heat supply. A group of researchers led by the Institute for Ecological Economy Research (IÖW) shows how cities can turn away from coal, oil and gas in a socially acceptable way. The project "Urban Heat Turnaround" investigated possible contributions from renewable energies and local heat sources in Berlin's urban neighbourhoods. "Waste heat from businesses, heat from waste water or geothermal energy have hardly been used so far.

Hamburg's new climate plan and new climate protection law

Senate adopts concrete measures for the next ten years and sets new CO2-targets for 2030 and 2050

December 3, 2019. Today, the Senate has set two decisive courses to achieve Hamburg's climate goals with an update of its climate plan and a new climate protection law. CO2 emissions are to fall by 55 percent by 2030, and Hamburg is to become climate-neutral by 2050. The climate plan describes the responsibility and the respective CO2 reduction targets in the sectors "transport", "private households", "trade, services, commerce" and "industry". It contains a large number of concrete measures which are to lead to the necessary reduction of CO2 emissions by 2030. The draft of the new climate protection law creates a binding legal framework for this.
