This assessment was used for training in Decision analysis and risk management 2015 course. To see student contributions, see a previous version.

Scope

Question

What is the energy need of buildings in Helsinki and the related greenhouse gas emissions and health impacts? How can these be affected by renovation of buildings and fuel changes in district heating?

Intended use and users

A problem in the climate policy practices in the City of Helsinki is that there is not enough information about different costs and impacts of different climate change mitigation measures, especially in the long term. This is slowing down the decision-making process. The results of this course will be used at the City of Helsinki Environment Centre to assess the outcomes of different ways to reduce GHG emissions. The results will help in identifying the most favourable ways to cut GHG emissions.

Participants

Boundaries

  • Time: 2010-2040
  • Spatial: the city of Helainki

Decisions and scenarios

  • Renovate 1 or 2 % of buildings per year.
  • Change the district heating fuel from 100 % fossil to 50 % fossil, 50 % wood-based fuel.

Timing

The data will be collected before the end of the Decision analysis and risk management 2015 course (12th May, 2015). The model runs will be finalised soon after that. Results will be available before September 2015.

Discussions

These are some resolutions of discussions within the assessment.

  • City level climate change mitigation is not useless although international treaties are important for success.D↷
  • Climate change adaptation is not more important than mitigation on city level.R↻
  • Citizens may have a key role in implementing city climate policies.D↷
  • Food issues are underrepresented in climate discussions although food is a major emission source.R↻
  • The role of district heating by nuclear energy in Helsinki is unclear.D↷
  • There may be large uncertainty in CO2 emission factors of biofuels.D↷

Analyses

Indices

The data will be classified according to these indices:

  • Building: Residential, Public, Industrial, Other. For separating different use purposes of buildings.
  • Constructed: Years of construction of the buildings in the format 1990-1999, 2000-2009, 2010-2013.
  • Heating: District, Electricity, Geothermal, Oil, Wood,

The results of each ovariable will be measuring these things:

  • buildings: total floor area in m2.
