Background
• Climate change mitigation is a global challenge, in which Russia has a very important position– Vast natural resources– Enabled the ratification of Kyoto Protocol
• Very large emission reduction potential in the entire energy chain– Production: boiler efficiency, fuel conversion– Distribution: electricity, district heat – Use: industry, housing
• This case study is a part of a larger research project ’Reduction of Greenhouse Gas Emissions in North-West Russia - Finnish Business Opportunities’

Triple Dividend in Greenhouse Gas Emission Reduction in Energy Use in Housing in Russia?
• Economic benefit– Reduced fossil fuel consumption– Emission Reduction Units with existing market value
• Environmental benefit– Reduced greenhouse gas emissions
• Soci(et)al benefit– Better quality of everyday living conditions– Improved infrastructure (district heating systems)

Technical Means to Achieve Savings in Energy Consumption in Private and Public Buildings
• Heat measurement systems will be installed for each consumer and in future payments are based on real consumption
• Connection schemas (space heating) that are based on direct connection are replaced with indirect connections (heat exchanger) and building-level automation systems will be installed
• Hot domestic water should be produced with heat exchanger by district heat (nowadays it is supplied directly from the district heating network)
• Piping systems inside the buildings are replaced with two-pipe system connected in parallel
• Radiators are equipped with heat risers• Repairing construction
