The Helsinki Energy and Climate Atlas is a data model-based tool that already contains a wide variety of information related to the energy, which can be freely used by property owners, city planners and companies providing energy saving services, among others. The Helsinki Energy and Climate Atlas will be further developed to support the energy efficiency of the building stock, the use of renewable energy and, in the future, adaptation to climate change in a visual and informative form.
The Helsinki Energy and Climate Atlas contains the following information:
Solar Energy Potential
- The amount of solar radiation in buildings on a monthly and annual basis
Heating Demand Prediction
- Heating energy demand prediction and building renovation estimates for almost the entire Helsinki building stock from 2020 to 2050
Geoenergy Potential
- 150-m / 300-m / 1000-m deep well potentials, groundwater areas, bedrock (rock types and thermal conductivity, specific heat capacity, density parameters for geoenergy calculations) and soil data to support geoenergy well design work
Energy Data of Buildings
- Municipal register information (e.g. heating method of buildings, usage, volume, building material)
- Repairs and alterations
- Protected buildings (protection markings)
- Calculated energy consumption of buildings by age group (heat consumption, user electricity, building electricity)
- Potentials and costs for improving the energy efficiency of a typical 1970s-80s building in the Merihaka district
- Energy performance certificates and proposed improvement measures
- Measured consumption data of HEKA buildings for 2015 and 2016 (district heating, building electricity, water consumption)
Some of the Atlas input data can also be downloaded as open data from the HRI service. The main responsibility for the content of the data lies with the environmental services of the Helsinki Urban Environment Division, and the City’s Executive Office's project Helsinki 3D+ has been responsible for technical implementation and visualization. VTT, Heka Oy, Helsinki Building Control and HSY have participated in the production of the information. Some of the data has been produced as part of the mySMARTLife-EU project.
