Climate change, air quality and housing – future challenges to public health (CLAIH)
Contents
Scope
Purpose
The purpose of the assessment is to evaluate the health impacts and costs in Finland in the future if different housing policies are undertaken.
More specifically:
- What would be the health impacts and costs in Finland in 2030 if the society preferred different residential building heating systems and building energy efficiency solutions and fuels and forms for district heat production?
- What would be optimal combinations of residential building heating systems, building energy efficiency and fuels and forms of district heating?
- What would be the amount of societal subsidies needed to ensure the transition to the preferred heating systems and energy efficiency in housing?
Preferences for different decisions on residential building heating and energy efficiency solutions are assessed from the perspective of a citizen. Total health impacts and all other societal costs (total costs to all citizens, costs from CO2emissions etc.) from different decision options are assessed from the perspective of the whole Finnish society, and the optimal distribution of societal subsidies for different heating system and energy efficiency solutions are evaluated based on the total costs.
Boundaries
- Population: Finland
- Assessment time frame: 2010-2030
- Evaluated activity: heat production and consumption in residential building stock (detached houses, row houses, apartment buildings)
- Evaluated exposures:
- Fine particles (PM2.5)
- Outdoor concentrations
- Indoor concentrations from domestic wood combustion
- Personal exposure
- Indoor dampness and mold
- Indoor Radon
- Indoor air temperatures?
- Fine particles (PM2.5)
- Evaluated health impacts:
- Mortality and morbidity due to long term exposure to PM2.5
- Asthma incidence due to long term exposure to PM2.5
- Asthma due to indoor mold and dampness
- Lung cancer due to indoor radon
- Other evaluated emissions: CO2
- Evaluated costs:
- Costs fron health impacts
- Costs from building stock heat production and consumption
- Costs from building stock heating system/energy efficiency renovations
- Costs from energy infrastructure changes (District heat production development)
- Costs from CO2 emissions
- Decisions to be evaluated relate to:
- Fuel options for district heating (for both large existing CHP plants and small scale district heat production)
- Form of district heat production (should there be more small scale district heat production?)
- Household heating system options
- Building energy efficiency improvement options
- Building air filtering
Underlying scenarios
- Climate change (temperature) scenarios based on IPCC
- A2 (heterogeneous world, rising population, slow technological change)
- A1B (rapid growth of world economy and population, advent new and more efficient technologies, balanced use of fossil and renewable energy sources)
- B1 (rapid development towards environmentally friendly technologies)
- Greenhouse gas emission reduction scenarios
Intended users
- Ministry of Employment and the Economy
- Ministry of Social Affairs and Health
- Ministry of the Environment
- Any interested party
Participants
- FMI
- University of Oulu
- THL
- Anyone interested
