good news for you is a platform that focuses on positive solutions. This includes everything that makes up each of us - starting with our own personality to relationships with others to societal, social, political processes.

Violet, green, blue and yellow - inside the innovative battery storage systems now available in the Climate quarter of the municipal utility company, will be colourful in the future. The electrolyte, which can store up to ten kilowatt hours of self-produced solar power, changes color depending on the state of charge.
Each of the new storage tanks holds 500 litres of the storage liquid. Redox-flow batteries in the cellars of the seven houses. The developers of the Dortmund-based manufacturer Volterion, a spin-off of the Fraunhofer Institute UMSICHT, installed and filled them themselves in Herne. This is because the climate district is an interesting technical demonstration object for them: Up to now, they have only installed battery storage systems in large-scale projects. In the single-family homes in Sodingen, the battery is only about the size of a two-door wardrobe.
Compared to conventional rechargeable batteries Redox-flow batteries are characterized by high operational reliability and extreme durability. Even a complete discharge does not harm them.
"With the battery, our energy concept of solar system and heat pump is now complete," explains Stephan Becker, project manager at the developer Stadtwerke Herne. "The climate quarter is now entering the home stretch." The final inspection with the future residents is scheduled to take place in about two weeks.
In April of last year, the municipal utility company began construction of the seven modern plus-energy houses. The small car-free model settlement combines the latest storage technology with renewable energy generation. The supply concept varies in individual details. With scientific support, the most efficient combination is to be found after the residents have moved in.
4,996 single- and multi-family houses in timber construction were approved in Bavaria in 2015. This early indicator from the State Statistical Office sets a new record in the readiness for timber construction. In terms of building permits, the timber construction rate is thus already at 19.6 percent. In the last 30 years, never before have so many residential buildings made of wood been planned in Bavaria and the above-mentioned value exceeds the construction completions of 2015 by nine percent or 429 residential buildings.
Wuppertal is making waves when it comes to sustainable and modern transport systems. It is not only the 100-year-old suspension railway that has long symbolised the city as an innovative mode of transport. The new northern railway line for cyclists and pedestrians above the rooftops of the city has brought great recognition nationwide. A modern urban cable car is planned as a new mode of transport and is hotly debated.
And now the renowned Wuppertal Institute for Climate, Environment and Energy has presented the study "Car-free city centre Wuppertal Elberfeld", which provides further impetus for the mobility turnaround in Wuppertal and builds on a changed mobility culture.
Sustainable development in Germany is inconceivable without a resource-efficient construction industry. The new expert recommendation VDI-EE 4802 Sheet 1 explains in a practical way how to apply the concept of resource efficiency in the life cycle of buildings. To this end, it breaks down the tasks and scope for action of the individual players in the construction process. Using examples of increased material, energy and space efficiency, the expert recommendation supports the entire planning process towards a resource-efficient building.
Modern construction must be sustainable, and keep the many different aspects in mind: the use as well as the costs, the consumption of resources and the cultural background. The energy used for new buildings and facilities must be planned precisely, and the subsequent energy requirements must also be calculated in such a way that they can be met with as little input as possible. Last but not least, the construction processes themselves should also be resource-efficient. In Germany, the Resource Efficiency Program (ProgRess) exists for this purpose.
Aim of the expert recommendation VDI-EE 4802 Sheet 1 is to enable those involved in construction to design their building projects in a resource-efficient manner, and in particular to minimise the use of fossil energy raw materials and the emission of greenhouse gases. The aim is to achieve an optimal, contemporary compromise between economic efficiency and sustainability.
Resource efficiency can be planned and measured. The VDI has developed the VDI 4800 series of guidelines which contains basic principles and methodology, strategies and evaluation procedures. The new VDI expert recommendation VDI-EE 4802 Sheet 1 fleshes out the contents of the directive and helps with its application in practice. The expert recommendation is aimed at those responsible in the construction and real estate industry, politics and administration.
VDI-EE 4802 Sheet 1 provides guidance on the determination of resource efficiency, which results from the determination of the quantitative use of resources. In this sheet, the spatial level of a building is considered, primarily for residential and non-residential buildings, as well as temporary buildings. Further sheets of the expert recommendation will deal with resource efficiency in neighbourhoods or cities.
Publisher of the VDI expert recommendation VDI-EE 4802 Sheet 1 "Resource Efficiency in Construction - Buildings" is the VDI Society for Construction and Building Technology (GBG). The expert recommendation was published in March 2021 and can be ordered at a price starting at EUR 110.90 from Beuth Verlag. Online orders can be placed at www.vdi.de/4802 or www.beuth.de possible. VDI members receive a 10 percent discount on all VDI guidelines. VDI guidelines can be ordered in many public display free of charge.
