Net Zero Energy Strategies and Planning Support Tools for Campuses and Residential Neighborhoods in Germany

摘要

Reducing CO_2 emissions by improving energy efficiency and integrating renewables while offering a high quality of living and working in neighborhoods and campuses, is the declared aim of the three German case studies described in this paper. The focus is to assess and analyze the different phases of an energetic retrofitting: planning, construction and operation. Planning tools using 3D geometry of buildings are applied to model efficiency scenarios and the potential contribution of local renewable generation. By means of a holistic approach including all relevant stakeholders, this paper describes the current experiences on very low carbon neighborhoods in Germany.
