10 SimStadt Heating demand Q h heating demand Q w hot water heating demand Q s solar gains Q i internal gains H T transmission heat loss H V ventilation losses 10

11 Used data sets: City of Ludwigsburg 3D City Modell LOD2 Building geometry (abstraction) Building function Census data set Micro census 2011 Building and building unit level 84% of all heated buildings Local weather data INSEL database Monthly temperature and irradiance 11

12 Data availability for residential buildings: 96% of residential buildings, But only 10% non-residential Relevant data sets for our analysis Year of construction (10 year categories) Number of building units / appartments (interval) Building function (again) Available data sets, but not useful for us Heated area (too large categories) heating type: no information on gas / oil / etc. 12

13 Buidling function (3D city model) Building units (census) Building height (3D city model) Ratio external walls (3D city model) Building type Year of construction (census) Deutsche Gebäudetypologie (aus IWU) 13

14 Deutsche Gebäudetypologie (2005) Bauphysikalische Details von jede Gebäudetypologie (Baujahr / Gebäudetyp) Empfohlene spezifische Sanierungsmaßnahmen 14
