This study presents and demonstrates a methodology for calculating the economic potential of photovoltaic installations in urban areas including the previously often disregarded potential on building façades. The analysis of a 2 km2 urban area has shown that building façades there provide almost triple the area of building roofs. However due to non...

In dieser Dissertation wird das akteursbasierte Wohngebäude- und Haushaltsmodell AWOHM zur Identifizierung und Konzipierung adäquater Bündel umweltpolitischer Instrumente im Themenfeld Wärmenutzung mit Fokus auf der energetischen Modernisierung entwickelt und auf die Bundesrepublik Deutschland angewandt. Dabei werden umweltpolitische Instrumentenbü...

In Germany the introduction of a feed-in tariff for renewable energies in the year 2000 led to a massive increase in newly constructed photovoltaic (PV) plants reaching a total installed capacity of 35 GW(p) as of November 30th, 2013. The distribution of these plants shows a large disparity between regions, which motivates investigations of regiona...

While BIM processes are established for new buildings, the majority of existing buildings is not maintained, refurbished or deconstructed with BIM yet. Promising benefits of efficient resource management motivate research to overcome uncertainties of building condition and deficient documentation prevalent in existing buildings. Due to rapid develo...

Results from CONCERTO initiative are presented.

This poster sums up different results from CONCERTO.

To compensate for seasonal price variations of bitumen for road asphalt, in addition to the usual approaches of forward-contracts and hot bitumen storage, innovative techniques for cold bitumen storage have emerged. As a case study, hot bitumen storage and additional integration of cold bitumen storage in the bitumen supply chain of the second larg...

The Energy Performance of Buildings Directive requires all new buildings to be nearly zero-energy buildings by 2020. In order to achieve this goal, energy efficiency measures have to be combined with on-site renewable energy production. Especially for high-rise buildings with large façade areas, the installation of a building-integrated photovoltai...

Construction and demolition (C&D) waste can be either directly disposed in landfills or processed in recycling plants as aggregates. Depending upon its physical properties, this recycled waste can be used in a variety of construction applications and also reduce dependence on natural aggregates. Since the recycling of C&D waste reduces landfill and...

Clean air policy faces not only the classical problems like multi-pollutant aspects but also complex consequences of instruments on production costs, competition and consumption. A new model can support clean air policy in Germany.
