    Smart Green Tower becomes an energy producer

    The Smart Green Tower is being built in the city of Freiburg. The 51-metre-high building will provide living, residential and working space. Depending on the solar radiation, a building envelope made of photovoltaic modules generates more energy via the photovoltaic system than can be consumed directly. In order to utilise the surplus electricity, the designers are using a flexible internal energy storage system with lithium-ion batteries.  more...

    Optimising heat pumps for multi-family homes

    Solutions for the application of low-exergy systems are being developed to supply heat to existing multi-family homes. This building services equipment includes electric and gas heat pumps as well as heat transfer and ventilation systems. Different system concepts are assigned to different building types and refurbishment processes and then evaluated. The aim is to realise and evaluate the developed heat pump systems and components in exemplary refurbishment projects.  more...

    From air base to residential neighbourhood

    A new residential district is being built on the site of a former air base in Oldenburg. In addition to new buildings, some of the former barracks buildings will be preserved and converted into residential buildings. A new infrastructure concept is planned that will couple the electricity, heating/cooling and electromobility sectors and integrate them into a cross-sectoral supply network. In addition, the project partners are developing a digital service platform to provide intelligent load and procurement management at the district level.  more...

    Monitoring verifies energy savings

    Systems with integrated phase change materials (PCMs) offer considerable potential for heating and cooling buildings more efficiently. However, so far there has been very little practical experience that has been underpinned by reliable measurement and monitoring data. In the PCM-Demo II research project, eight partners from research and industry are investigating and assessing PCM systems in various applications in the building sector. The preliminary results are now available.  more...
     

    Modern living in an historic urban district

    The Margaretenau residential district in Regensburg is being modernised to improve its energy efficiency. The designers are developing a solar-active and -adaptive exterior render system as a replacement for conventional thermal insulation for the facades. This should increase the solar yields and improve the thermal comfort inside the buildings. The energy supply will be provided by a new and efficient hybrid heating system consisting of cogeneration and heat pump technology.  more...

    Software assesses lifecycle costs

    Building projects often specify components that are the cheapest to buy – which in the long run is not always the most cost-effective and efficient solution. Together with Dresden scientists, software provider Hottgenroth has developed a program module that helps to determine and optimise the lifecycle costs of components and system technology. It is now available as a module integrated into existing energy consulting and planning software.  more...
     

    Ten outstanding concepts awarded

    On 6 December 2017, ten outstanding and innovative concepts were awarded prize money totalling 280,000 euros at the German Federal Ministry for Economic Affairs and Energy in Berlin. The respective juries awarded five winners in both the “Concepts for Future-oriented Buildings and Districts” category and in the “Ideas for an International Energy Competition” category in the ideas competition held by the EnEff.Gebäude.2050 funding initiative.  more...

    Profitability of energyoptimised buildings

    “Does that really pay off?” – this is something you often hear when people are talking about energyoptimised new buildings or refurbishment projects. Germany’s Energy Saving Act also formulates a requirement for cost-effectiveness. It is not easy to answer this question. For this reason, the terms ‘economic viability’ and ‘economically advantageous’ will first be defined.  more...
     

    Differentiated assessment of economic benefits

    Nowadays, it is relatively easy from an engineering viewpoint to construct buildings with extremely low energy requirements. However, is it also possible to achieve this energy level, which is ambitious in terms of planning, building technology and commercial considerations, with existing buildings on a large scale? And is this advantageous from a financial point of view? In the BINE interview, Professor Thomas Lützkendorf from the Centre for Real Estate at the Karlsruhe Institute of Technology (KIT) discusses the statutory framework conditions, calculation methods and data bases for transparently determining the economic benefits of energy-optimised buildings.  more...
     

    On-roof insulation made of cattail plants in development

    Energy-saving in the production, pressure-resistant and compostable: Researchers at the Fraunhofer Institute for Building Physics have high expectations for the insulation boards made from the leaves of the Typha plant. Together with industrial partner Saint Gobain Isover, they are now further developing a board for insulating rafters and preparing its series production.  more...
