    Gas engine heat pump supplies renovated residential complex

    The energy efficient renovation of apartment buildings from the post-war years was aimed at achieving a CO2-neutral energy supply in conjunction with the use of renewable energies. The core element of the new heating system is a gas engine heat pump that uses groundwater as the heat source. This not only supplies the low-temperature space heating but simultaneously heats the domestic hot water efficiently.  more...
     

    School: Refurbished from Plattenbau to Passive House

    The school building belonging to Max Steenbeck Secondary School in Cottbus was old and the extent of the building damage made it impossible to carry out renovation work during the school's ongoing operation. This meant that the school had to move. To this end, an old system-built “Plattenbau” school with an auditorium and gymnasium had to be first of all comprehensively modernised. The City of Cottbus placed high demands in terms of the energy consumption, comfort and operating costs.  more...
     

    Web portal for energy-optimised buildings and districts

    The website of the ENERGIEWENDEBAUEN research initiative is now online. The German Federal Ministry for Economic Affairs and Energy is bundling its long-standing subsidy measures entitled Energy Optimized Building, Energy-Efficient City and Energy-Efficient Heating and Cooling Networks, and also research on thermal energy storage and low-temperature solar thermal energy systems in the redesigned research initiative. They are being brought together under one umbrella initiative.  more...
     

    "We have to increase our efforts!"

    The first ENERGIEWENDEBAUEN conference took place in Berlin from 30 - 31 January, 2017. Some 350 participants from research, academia, architecture and planning offices, politics, energy suppliers, cities and municipalities as well as the real estate industry discussed how the energy supply of buildings and districts could be made future-proof. The aim of the German federal government is to create a climate-neutral building stock by 2050. This will not be easy to achieve.  more...
     

    Fresh air without mechanical ventilation

    Ventilating non-residential buildings naturally but in a controlled manner saves primary energy and requires lower investment and operating costs than mechanical ventilation systems. Scientists from Stuttgart University have therefore developed a ventilation concept that ensures a good indoor environment and reduces the electricity consumption for operating the ventilation system.  more...

    Refurbishment roadmaps for districts

    So far, the rate of refurbishment of the building stock has been around one per cent. How could the annual refurbishment rate be increased significantly – to about three per cent? Together with municipalities, researchers are looking into obstacles while developing refurbishment plans for differently structured model districts. As planning instruments, these plans are intended to help municipalities tap into previously unused refurbishment potentials.  more...

    Learning and working in an energy-plus school

    Uhland School in Stuttgart, which dates back to the 1950s, no longer accorded with today's structural and energetic standards. The renovation work is now almost complete and the City of Stuttgart is getting its first energy-plus school. A photovoltaic system on the roof and façade of the building covers the electricity requirement.  more...
     

    Energy-efficient use of university buildings

    Using the Ludwig Maximilian University of Munich as an example, researchers want to show how efficiency improvements can pave the way for a climate-neutral university campus. In the project HoEff-CIM, the buildings are reproduced and evaluated in a model with the aim of developing appropriate refurbishment strategies and an energy management system for building operation.  more...

    Calculating and comparing refurbishment costs

    Maintaining and refurbishing municipal properties to improve their energy efficiency costs money that in many cases is lacking. A new software program now makes it possible to calculate different refurbishment scenarios for existing municipal buildings and to compare them in detail. This helps to strategically plan the investment in cities and local communities.  more...

    Excellent climate for ancient manuscripts

    The new Central Library combines the book collections that were previously spread across several locations. Luitpoldhaus, which is located in a listed ensemble of buildings in Nuremberg’s old town, has been rebuilt and expanded. The project aim of undercutting the requirements of EnEV 2007 for new-build schemes by at least 30% has been exceeded. However, the high demands placed on the indoor environment for archiving and exhibiting medieval manuscripts made the task extremely tricky.  more...
