That sand is the rock of the year has probably not noticed very many. Why that is so, about it reports the contribution "Sand - the underestimated raw material" (28 min.) from 11.9.2016 on ZDF. Because experts warn: Our little-known sand hunger could become a global sand crisis in the future.
Because:
- Worldwide, 15 billion tons of the granules are consumed annually - and the trend is rising.
- Every German uses an average of 2.9 tons of sand per year. About 80 percent of this is used in houses, roads and bridges.
- 200 tons of sand stuck in a family home
- 30,000 tons of sand stuck in one kilometer of six-lane highway
Building material recycling of sand or mineral building materials is possible, but in practice it is mainly downcycling. For this reason, the substitution of mineral building materials with renewable building materials is favoured in concepts for ecological buildings. Numerous settlements and quarters show what this can look like in concrete terms:

Neues Berlin and Berliner Stadtwerke expand cooperation

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.
The solar plants, which together cover 4,000 m², are being erected on a total of 23 six-storey buildings between Falkenberger Chaussee, Rüdickenstraße and Am Breiten Luch, near the Hohenschönhausen S-Bahn station. They will enable around 420,000 kilowatt hours of green electricity to be harvested per year and around 235 tonnes of the greenhouse gas CO2 save.
"We are very pleased that Neues Berlin has already started the third project with us, which is also quite large by Berlin standards," says Dr. Kerstin Busch, Managing Director of Berliner Stadtwerke, who points out that there is further potential for expansion in the Mühlengrund residential complex. "Although we are calling for improvements in the current EEG draft - for example, with regard to the obligation to tender or the supply of tenant electricity to neighbouring buildings - we see that tenant electricity can currently still succeed under certain conditions and in close communication with the residents and the cooperative, even under difficult conditions."
"Together with Berliner Stadtwerke GmbH, we have implemented environmentally friendly supply projects based on renewable energies on our roofs in a very short time and without much effort. We are looking forward to further projects like the one in Mühlengrund to give even more tenants the opportunity to benefit from tenant electricity. During the cooperation, it quickly became apparent that both sides are pursuing the goal of making an ecological and social contribution to our city with the greatest interest," says Thomas Fleck, member of the board at Neues Berlin.
In 2019, Berliner Stadtwerke and the housing cooperative Wohnungsbaugenossenschaft Neues Berlin have already successfully implemented a tenant electricity project in the residential complex Malchow floodplain in Hohenschönhausen. Since then, around 640 households have been able to obtain cheap green electricity from their own roofs. To this end, a total of five solar power systems with a total capacity of 224 kilowatts were installed on four buildings belonging to the cooperative. This year, Berliner Stadtwerke added an existing solar power system on the Neues Berlin building Degnerbogen converted to an intelligent tenant power system - a smart model for owners of PV systems that will fall out of the EEG subsidy in the future.
For Berliner Stadtwerke, the implementation of local green electricity projects is an important milestone in enabling a climate-friendly and affordable supply for all residents. To this end, solar power systems are being installed in residential areas and on public buildings, among other things, in order to generate clean electricity where it can be consumed. In addition to this local system expansion, Berliner Stadtwerke offers a range of solar energy services with its berlinStrom tariff municipal green electricity throughout the city. Today, Berlin's only public energy supplier counts more than 19,000 green electricity households among its environmentally conscious customer base.

Now that almost all of the 570 apartments in Germany's largest timber housing estate in Prinz-Eugen-Park have been occupied, the Munich planning committee has recommended the implementation of the follow-up timber construction project "Kreativquartier" with 370 units.

The new housing development "Ludmilla Wohnpark" was built in Landshut with more than 180 residential units in plus-energy construction. Five single-family houses, two semi-detached houses, six terraced houses and eight multi-family houses with a total of 55 flats were built on a plot of around 7,300 square metres.
Researchers from Munich University of Applied Sciences and the Technical University of Dresden are evaluating the quarter and optimising the technology in operation. There is an initial report on this in the BINE-Info: www.bine.info/...plusenergie-konzept-in-siedlung-getestet
(the ESD info service was discontinued at the end of 2020)
