How can climate change affect housing construction?

alternative energy: Alternative climate protection

In 2017, twice as much was invested in renewable electricity generation than in fossil fuel. Currently 54 percent of the world's 1,013 gigawatts of installed power is from wind and 46 percent from solar energy. 97 percent of wind energy comes from the mainland. Forecasts assume that solar and wind will reach the next trillion watts in 2023 and that solar energy will have a larger share. Europe is lagging behind. A large part of the service is installed in Asia and therefore also an industrial advantage.

More competitiveness

"Europe needs the energy transition not only because of environmental protection, it is about added value and competitiveness. Industry needs a signal and European partners in order to advance the energy transition," said Maringer. "Germany and Denmark show how it works. Of course, representatives of the highly subsidized fossil fuel economy slow down and block."

The global turn to renewable energies creates an opportunity for technologically advanced countries like Austria. "During the EU Council Presidency there is the possibility to use this. Austria is not only responsible for a new design of outdated fossil electricity markets. It is also sitting at the table for a long-term EU budget, climate and energy plans up to 2050 and must have plans and a present new energy law. The latter must ensure that the goal of 100 percent renewable electricity generation will be achieved by 2030 and that Austria will participate in the global trend. "

Clever planning shows that the sun, wind and the storage capacity of building materials can make an important contribution to climate protection. In the Mühlgrundgasse in Vienna, the non-profit housing developer "Neues Leben" is building a complex with 155 apartments in cooperation with the real estate developer "M2plus Immobilien GmbH". The special thing about it: Here, for the first time, thermal component activation is used for heating and cooling with wind energy in social housing. The technology is simple: the concrete is activated via built-in pipe systems in which hot or cold water flows as required.

"The apartments are heated with geothermal energy and also cooled in summer, the heat pump is operated with excess wind power. For a 70 to 80 square meter apartment, the annual bill for heating, cooling and hot water should be less than 300 euros, such low energy costs support affordable living . This project will by no means remain an isolated case, "says Johann Gruber, chairman of the property developer" Neues Leben ", with conviction.

Project partner and project developer Norbert Mayr, managing director of "M2plus", had the idea of ​​storing excess wind energy in concrete and made contact with energy planner Harald Kuster. Kuster, recently awarded the Energy Globe 2018 Salzburg for services relating to component activation, is responsible for planning the system with his company "FIN - Future is now": "The MGG22 project helps ensure that we have the necessary existing concrete components of a building With a simple solution, we can use it sensibly as storage mass. In addition, we use renewable energy when it is 'abundant'. " There are prime examples of buildings with alternative energy sources - such as the new TU Wien building on Getreidemarkt.
