Helsinki Publishes Energy and Climate Atlas on 3D City Model
The 3D atlas is a tool for implementing energy efficiency improvements in buildings
The City of Helsinki has compiled extensive energy-related data on the Helsinki building stock into Energy and Climate Atlas and makes the atlas available as open data. The atlas is executed and visualized on Helsinki’s 3D city information model, which allows easy utilization and further application of the data. The atlas is a part of the toolkit that helps Helsinki to cut carbon dioxide emissions and eventually to reach carbon neutrality.
The Helsinki Energy and Climate Atlas contains both real and calculated building-specific data. The information includes energy efficiency upgrades, performance classifications, and the energy sources used for heating – whether the building utilizes district heating, geothermal energy, electricity or other. The atlas also shows the estimated energy consumption of buildings as calculated by the Technical Research Centre of Finland VTT. Further, the atlas presents building-specific solar energy potential.
“The atlas is a tool for city planners and decision-makers to assess the potential and available resources for energy efficiency improvements. Property owners and managers can use the atlas to assess the property’s energy consumption,” says Environmental Planner Petteri Huuska of the City of Helsinki Environmental Services, in charge of the atlas development.
“Energy and Climate Atlas was executed with the CityGML city information model, which can be used for advanced city analyses and simulations. The atlas covers the entire city, so it enables an easy citywide energy survey, as well as assessments of specific buildings,” says Enni Airaksinen of Helsinki’s 3D city information modeling project.
In accordance with Helsinki’s principles concerning public data, all data presented on the 3D model including Energy and Climate Atlas is released as open data available freely for the development of new knowledge and applications.
The development of Energy and Climate Atlas on the 3D city information model continues. Plans for new datasets involve the renewable energy potential of buildings and data that could be used in measures to adapt to climate change, for example, in the management of flooding caused by heavy rainfall.
The 3D atlas is an important tool for Helsinki in achieving the city’s key strategic climate goal to cut greenhouse gas emissions by 80% and to become carbon neutral by 2035.
The atlas has been produced by the City of Helsinki 3D project and Environmental Services using energy data from public sources. The atlas is part of the mySMARTLife project, in which Helsinki develops smart commercial-scale solutions to cut urban carbon dioxide emissions together with other European cities.
