Climate change mitigation in housing describes possible actions to change the building stock in an aim to reduce greenhouse gas emissions.
Scope
What are probable actions to change the building stock in an aim to reduce greenhouse gas emissions?
Definition
Data
- Climate change policy assessment
- Energy efficiency of buildings in Finland
- Heating systems in buildings in Finland
- Housing data sources
- Public health impacts of GHG emission reduction strategies in household energy use

| No change to recent trends. | Effort described by most stakeholders as achievable. | Effort needing significant change - hard but deliverable. | Heroic effort, but does not break any laws of physics. | |
| Average temperature of homes | 1 Average room temperature increases to 20 C (a 2.5 C increase on 2007) | 2 Average room temperature increases to 18 C (a 0.5 C increase on 2007) | 3 Average room temperature decreases to 17 C (a 0.5 C decrease on 2007) | 4 Average room temperature decreases to 16 C (a 1.5 C decrease on 2007) |

| Home heating electrification | A The proportion of domestic heat supplied using electricity is 0-10 %, as today. | B The proportion of domestic heat supplied using electricity is 20 %. | C The proportion of domestic heat supplied using electricity is 30-60 %. | D The proportion of domestic heat supplied using electricity is 80-100 %. |
| Home heating that isn't electric | A The dominant non-electric heat source is gas (biogas if available). | B The dominant non-electric heat source is coal (biomass if available). | C The dominant non-electric heat source is waste heat from power stations. | D A mixture of gas/biogas; coal/biomass; and heat from power stations. |
| Home light & appliance demand | 1 Energy demand for domestic lights and appliances increases by 20 % (relative to 2007). | 2 Energy demand for domestic lights and appliances is stable. | 3 Energy demand for domestic lights and appliances decreases by 40 %. | 4 Energy demand for domestic lights and appliances decreases by 60 %. |
| Home light & appliance technology | A Energy used for domestic cooking remains at 63 % electricity and 37 % gas. | B 100 electric. | C As for B. | D As for B. |
