    "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...
     

    Fun in a passive house pool

    The monitoring shows that the thermal heat and electricity consumption can be reduced even further during ongoing operation if the building is well-regulated, optimised and continually monitored. The public swimming pool complex in Bamberg consumes over 50 per cent less heat than comparable leisure pool facilities. A thermally high-quality building envelope allows indoor air humidities of up to 64 per cent. This reduces the pool water's evaporation rate and the necessary air change rate for providing dehumidification. This therefore also reduces the electricity and heating requirements.  more...
     

    Efficiently heating & cooling non-residential buildings

    The use of environmental energy to cool or, in combination with heat pumps, to heat non-residential buildings via thermo-active building systems (TABS) has established itself in recent years. The objective of such building and system concepts is not only to consume as little energy as possible in quantitative terms (low energy), but also to achieve the most optimal energy conversion in thermodynamic terms that takes the quality of the energy used into account (low exergy, „LowEx“).  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...
     

    Heating buildings via their exterior walls

    Surface heating systems facilitate the integration of renewable energy sources and reduce energy costs. However, since the retrofitting of underfloor heating is very expensive, thermally activated walls provide an option in existing buildings. For the first time scientists at Saarland University are testing the use of capillary tube mats in exterior wall heating.  more...
     

    “Rethinking collectors from a construction industry perspective”

    The trend towards zero-energy and energy-plus buildings has also increased the importance of using roofs and facades for the generation of renewable energy. The TABSOLAR research project has resulted in the development of new thermo-active building systems that are suitable for industrial prefabrication and can be used in a wide range of applications.  more...
