Topic 4

Redevelopment strategy and energy-efficient architecture of the HFT inner-city campus <<

Management: Prof. Dr. Jan Cremers

For the most relevant construction with the greatest leverage effect on the university campus, identified in topic 2, detailed redevelopment strategies on the component level will be compiled and documented. This will include the optimization of components with regard to summer and winter thermal protection; for instance, by means of insulation or by incorporating Phase Changing Material (PCM) components and the enhancement of daylight use.

An important aspect is the investigation into the redevelopment possibilities of façades architecturally deserving of preservation, or listed, in collaboration with the historic buildings protection authority. Up to three versions of energy redevelopment proposals will be drawn up per building. At the same time, an optimization of the redevelopment versions will take place in respect of climate neutrality in life-cycle assessment and requirements according to the criteria of the DGNB (German Association for Sustainable Building) for sustainable buildings and city neighbourhoods. Based on this information, a building component catalogue for typical redevelopment possibilities based on a sample building will be developed and a prioritising of the measures for the master energy plan undertaken. Furthermore, under this topic, additional construction measures for the integration of sustainable energies will be identified such as roofing over courtyards, altering the edges of the roofs and so on. In addition to this, an investigation will be made into the extent the planning and carrying-out of procedures for installing sustainable and necessary technical elements on the buildings’ exteriors will affect the typical townscape façades while still guaranteeing the best possible visually inconspicuous and harmonious integration of all elements. After considering the buildings’ exteriors and perhaps other building components, the passive and active measures will be consolidated into an overall concept together with feedback from additional work packages. Subsequently, the climate neutrality in operation will be evaluated in collaboration with the other participants and readjusted as necessary.
