“What if the renewal of Rinkeby-Kista, Stockholm, were to make it part ofa 2 kW Society?” Renewal of the city district’s 25 000 flats from the 1970s is dueand a network organisation, “Järva Boost” is established. A cross-disciplinary teamof KTH researchers develop a computerised model to simulate energy efficiencygains resulting from actors’ decisions. Inputs are measures that building owners,energy providers, residents, planners etc. might propose. They can be technicalinstitutional or socio-cultural. Outputs are energy use in kW/person and CO2emissions. To guide model development, an “ideal type” usage situation isoutlined. The energy system is modelled “upstream” from end use, to identify largerefficiency potentials. The model interface is designed to enable the “staging” ofactors’ negotiations: The manager influences the properties of the climate shell, theresidents the energy used for cooking, and the energy provider the primary energymix. The concepts of “Household Activities System” and “Energy Usage Systems”give theoretical framework for modelling. The former conceptualises residents’activities, the latter the technology providing services to the activity. Simulationsgive contrasting outcomes: “business as usual” vs. ”most favourable”.

Negotiated Outcomes – Actor-oriented Modelling of Energy Efficiency in a Stockholm City District Renewal
