 In 2008, urban planning competitions were held for the ‘Wohnen an der Promenade’ residential area along with the special use & science area ‘Campus II’, where dormitories, educational facilities and research-intensive companies were to be located. These two areas constitute the core of the first construction phase at the Bahnstadt (Figure 1); a residents' survey was carried out here, and the results are presented below. Construction of the first residential projects began in 2011, and the first plot was finished in 2012. Marketing of the residential units was very dynamic right from the start. Buyers had very positive views of the Passive House Standard and other sustainability concepts in the Bahnstadt, which were decisive for many of the buyers. In 2008, urban planning competitions were held for the ‘Wohnen an der Promenade’ residential area along with the special use & science area ‘Campus II’, where dormitories, educational facilities and research-intensive companies were to be located.

 As an area to be redeveloped and because of its central location, the Bahnstadt is an excellent location for sustainable urban development. In accordance with the city of Heidelberg’s climate protection and sustainability goals, professional concepts for various environmental aspects were worked out. As an area to be redeveloped and because of its central location, the Bahnstadt is an excellent location for sustainable urban development.

 Together with the engineering office ebök, an energy concept was developed for the Bahnstadt [ebök 2007]. Various building standards and heat supply variants for the building structures as envisaged in the master plan were assessed in terms of CO2 emissions and costs to be used as a basis for decisions. On this basis, Heidelberg’s city council decided to make the Passive House Standard compulsory for the entire district, which would also be supplied with district heat from renewable energy. To encourage the sensible use of electricity, a power-saving concept was also worked out [Stadt Heidelberg 2012]. Together with the engineering office ebök, an energy concept was developed for the Bahnstadt [ebök 2007].

-The energy concept was specified as a development goal for the Bahnstadt and was made binding using other legal and contractual instruments. Intensive PR work and sophisticated quality assurance in the planning and construction phases were decisive for compliance with the Passive House standard. The legal instruments and the quality assurance were presented in detail at the 2013 International Passive House Conference [Bermich 2013] [Persch 2013]. The first assessments of heat consumption in the Bahnstadt projects confirmed the successful implementation of the Passive House standard and <fc #98fb98>were</fc> presented in detail at the 20th International Passive House Conference by Peper and Persch [Peper 2016].+The energy concept was specified as a development goal for the Bahnstadt and was made binding using other legal and contractual instruments.

 When asked about why they chose a Passive House home, 22 % of those surveyed said they did so “out of personal conviction / for sustainability reasons”, which is a very high value for an energy/environmental criterion (Figure 2). Reports from Sparkasse Heidelberg Immobilien also indicate that the Passive House standard was one of the most important criteria in sales and rental discussions. It can be assumed that the energy standard, which is an important image factor for the Bahnstadt, also played a role in the other answers. When asked about why they chose a Passive House home, 22 % of those surveyed said they did so “out of personal conviction / for sustainability reasons”, which is a very high value for an energy/environmental criterion (Figure 2).

 Figures 3 and 4 show answers to the question about satisfaction with living in a Passive House building. On average, 76 % of residents are satisfied or very satisfied, which is a positive result. Figures 3 and 4 show answers to the question about satisfaction with living in a Passive House building.

 The question about satisfaction combined with information about special features of the Passive House homes reveals that residents who were informed in advance were much more satisfied (Figure 5). This finding shows how important it is to inform buyers and tenants. The question about satisfaction combined with information about special features of the Passive House homes reveals that residents who were informed in advance were much more satisfied (Figure 5).

 In the past, we were often confronted with concerns that ventilation systems would be too complicated for residents. The answer to the question of whether using the ventilation unit was easy or complicated shows a clear result (Figure 6). In the past, we were often confronted with concerns that ventilation systems would be too complicated for residents.

 But regardless of whether the assessment of temperature as too high was a specific result for the Passive House standard or whether other construction standards face the same, if not more, criticism, there is a need to take greater account of the summer climate in residential buildings in the future. But regardless of whether the assessment of temperature as too high was a specific result for the Passive House standard or whether other construction standards face the same, if not more, criticism, there is a need to take greater account of the summer climate in residential buildings in the future.
