Decarb Cities Forum 16 Mai 2018, Vienna, Austria The Building stock modelling (BSM) An instrument for spatial urban energy planning in the City of Zurich Tool to assist authorities, urban energy planners and utilities Dr. Martin Jakob, TEP Energy
Challenge: Ambitious goals, how to achieve?
Countries, regions, cities, and communities…
… lack a tool that allows linking goals to implementation
Policy Urban Energy
maker Planner
Solution: Building stock modelling
The building stock model (BSM) allows describing the status quo,
modelling development pathways and monitoring their progress on them.
Policy Urban Energy
maker Planner
Approach
In 4 distinct steps
1. Step: Analyse current situation:
establish energy and GHG emission balance
2000 2017
2. Step: Goal setting and strategic approach:
Measures and their impact at city scale
2005 2010 2015 2020 2025 2030 2035 2040 2045 2050
2017 2050
3. Step: Integral assessment of demand,
efficiency and renewable by zone/district
4. Step: Data for Energy planning at high
spatial resolution (hectare, block,
area or building scale)
