Extensive geothermal heat survey steers Helsinki towards its carbon neutrality goals<\/h2>\n

Helsinki is preparing a new underground master plan to steer the planning of large rock spaces and tunnels. The plan will also contribute to planning a denser urban structure, as underground and rock spaces can be utilised in a versatile manner and functions can be transferred underground.<\/p>\n

When it was time to update the underground master plan, Sweco\u2019s experts carried out a geothermal heat survey to support the process. \u201cThe plan proposal is expected to be completed at the turn of the year,\u201d says\u00a0Eija Kivilaakso<\/strong>\u00a0from the City of Helsinki\u2019s City Planning Department, who is responsible for the plan.<\/p>\n

Geothermal heat is expected to be the solution to both the increasing population numbers and the City\u2019s climate goals. The City of Helsinki aims to achieve carbon neutrality by 2035. One solution worth considering is geothermal heat. \u201cCarrying out a survey on the potential of geothermal heat became necessary while we were preparing the planning principles of the new underground master plan,\u201d says Project Manager\u00a0Pekka Leivo<\/strong>\u00a0from the City of Helsinki\u2019s Technical and Economic Planning Unit.<\/p>\n

Sweco\u2019s experts surveyed whether the underground resources are sufficient for building both geothermal wells and new underground spaces, as well as facilities such as traffic tunnels and water management plants, in different areas. \u201cWe also assessed how much of the city\u2019s total heating needs could be covered with geothermal heat,\u201d states land use specialist, Architect Maritta Heinil\u00e4<\/strong> from Sweco.<\/p>\n

Dense urban construction poses a challenge to geothermal heat<\/h3>\n

Helsinki\u2019s underground master plan in 2011 was the first of its kind. The geothermal heat survey by Sweco was also the most extensive one ever carried out in Finland. One part of the survey focused on land use planning, involving environmental impact assessments and geographic information surveys.<\/p>\n

\u201cWe also sought solutions to legal questions, as equal treatment of landowners is highly important in the planning process and thus in the planning of geothermal heating,\u201d Heinil\u00e4 emphasises.<\/p>\n

Another area was the planning of geothermal heat and energy systems. \u201cWe assessed the City\u2019s total heating needs and simulated geothermal heat fields exceptionally one area at a time. The conventional way is to carry out the simulations building by building,\u201d says geothermal heating system specialist\u00a0Mika Penttinen.<\/p>\n

It was important to the City of Helsinki that matters were examined from several different perspectives. \u201cSweco has very broad subject matter expertise in regard to land use and technical planning,\u201d Leivo says.<\/p>\n

Combining building services data with geographic information revealed where there was space for geothermal heat. \u201cDensely placed and tall buildings are often at odds with the spatial requirements of geothermal heat systems. The greatest potential lies in single-family house areas,\u201d says Sweco\u2019s Lifecycle Design Project Manager\u00a0Niina Laasonen<\/strong>.<\/p>\n

The survey provided the City with information for further planning. \u201cWe now know the potential of geothermal heat and that geothermal heat does not work as a property-specific system in efficiently built areas,\u201d Leivo says. \u201cWith that in mind, we should turn our attention to regional geothermal heat systems. That will enable us to utilise the potential of geothermal heat in the best possible way.\u201d<\/p>\n

Construction of geothermal wells must begin this year<\/h3>\n

The survey indicates that geothermal heat can be used to ensure the achievement of Helsinki\u2019s carbon neutrality goal and produce, according to a theoretical calculation, 14\u201318% of the City\u2019s total heating need in 2035.<\/p>\n

The geothermal heat capacity will only be sufficient if the City\u2019s heating needs remain at their current level. \u201cHarnessing the potential of geothermal heat requires immediate action, such as energy renovations by housing companies and space reservations for regional energy solutions,\u201d Laaksonen says.<\/p>\n

The City is ready for the next steps. \u201cIf we adopt geothermal heat as part of normal land use and public utility planning, it will facilitate the implementation of regional geothermal heat systems outside block areas as well,\u201d Leivo concludes.<\/p>\n
