David’s Corner is a demonstration project carried out within the framework of the guidance research project “Gründerzeit mit Zukunft” aimed at improving the current refurbishment standards and energy efficiency of buildings constructed during the period of rapid industrial expansion (period buildings). The project demonstrates a novel integrated approach to improve the energy efficiency of such buildings by incorporating an innovative technical concept during the refurbishment of an ensemble of three neighbouring period buildings in a non-lucrative location (total cost of refurbishment approx. 5m Euros). By utilising an innovative system consisting of retrofitting a central ventilation system with heat recovery in combination with a centralized heat supply that integrates renewable energy sources, the heating demand of the ensemble is reduced by a factor of 5, from 120 to 24 kWh/m2a.
The main aim of this project is the development of a future-oriented integrated solution for the refurbishment of period buildings that is economically viable under the given municipal funding conditions for the refurbishment of residential buildings. The technical solutions applied in this project are developed mainly from the findings of a feasibility study carried out in the sub project SP 2 “Grundlagen und Machbarkeitsstudien” (fundamentals and feasibility studies) as part of the previously mentioned guidance project.
