    "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...

    Fuel cell generates electricity and heat for homes

    Highly efficient, low-emission and quiet: as small-scale combined-heat-and-power stations, new fuel cell heating units produce heat energy and electrical energy with an efficiency of over 90 per cent. They have proven themselves in extensive tests in single and two-family homes, and their operation and design have been improved incrementally. The first units are now on the market. They run on natural gas, and on hydrogen and methane produced using renewable energy or biomass. Decentralised fuel cells can generate demand-oriented electricity, and they can be used in a grid-friendly or grid-independent way.  more...

    Assessing solar houses in energy and economic terms

    With the German Energy Savings Ordinance 2016, the maximum value allowed for the annual primary energy requirement for new residential buildings has been reduced by a quarter. This is not a problem in solar houses: they require a maximum of 15 kWh/(m2p.a.) of primary energy for heating energy and auxiliary power and are therefore well below the requirements of passive houses. The cost of this good CO2 balance can be determined using a newly developed simulation method.  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...

    New lighting strategies for streets, footpaths and squares

    LED is the future of street lighting. The LED Walkway on the grounds of Berlin’s Technology Museum, which opened in March 2015, demonstrates potential applications. The lighting technology developed allows the lighting level and light conditions to be adapted to external factors such as weather conditions and traffic volume. Spaces can now be set to a defined brightness with minimum stray light. The “StEffi Street Lighting” research project, launched in May, aims to develop and evaluate concepts for space-specific lighting and increase the potential savings with LED technology.  more...
     

    Cooling with solar heat

    The cooling or air conditioning of buildings with solar heat has a particular appeal because the heat demand and supply are usually consistent with each another. Cold stores in southern climates and many process refrigeration systems also require considerable energy when the sun shines intensely. The use of solar cooling systems instead of electric chillers also eases the grid, particularly at peak load times.  more...
     

    Clean heating with wood

    Despite considerable advances in firing technology, harmful particulate matter is produced when wood is combusted. Electrostatic separators, however, filter up to 90 per cent of particulate emissions from biomass boilers. These therefore enable wood burners to use a wider range of fuel and still meet the tightened requirements of Germany‘s 1st Ordinance on the Implementation of the Federal Immission Control Act. The major advantage: Both new and old heating plants can benefit from the new system.  more...
