Three different residential buildings served as case studies. First, we documented and analyzed the existing collaboration through documents and interviews. Based on this, we defined planning, management and communication tasks and processes. Additionally, we developed and implemented stakeholder-specific communication strategies and measures on topics such as heating, ventilation, washing and drying. Three approaches were considered very effective: push information for tenants and raising their awareness about energy-saving opportunities, as well as building a community through the training “energy mentors” who advise their neighbors.
On this basis, we developed a management model for collaboration and communication for the energy-optimized operation of residential buildings (ZUMOD). This model enables owners and management to better understand the needs of residents and use this knowledge for energy-saving, cost-efficient building operation.
