3 Why Energy Auditing in Finland? The international climate protocols oblige Finland to reduce emissions Finland s National Climate Strategy lists the means to reach the targets Finnish Energy Strategy and Energy Conservation Programme support the Climate strategy Voluntary Agreements and Energy Audits are important elements Improving energy efficiency and increasing the amount of renewable energy sources will cover about 50% of the emission reduction targets 3

5 Brief history 1 Energy audit subsidy scheme by Ministry of Trade and Industry : Motiva established Responsible for creating an energy audit program 1994: Program level activity started 1995: Full scale monitoring system established 1997: Energy audits integrated into voluntary agreements (Industry, Public and Private service sectors) 5

6 Brief history : Three new audit models introduced Energy intensive process industry included 1999: Systematic quality control process developed 2000: New version of calculation tool Motiwatti introduced 2001: The ninth energy audit model put into force 2002: 1000th auditor authorized 2003: Renewables integrated into audits and energy audit program updated 6

7 Connections of the Energy Audit Programme The Voluntary Agreement Scheme launched in 1997 a significant carrier for energy audits organizations within the VA scheme are obliged to implement energy audits high coverage The Condition Assessment Scheme for residential sector Other activities environmental and energy management systems commercial audits (compressed air systems etc) 7

8 Total consumptions, energy costs, saving potentials and investments of 3655 energy audits in the service sectors (96,4 milj. rm 3 ) reported during the period Present consumption SERVICE SECTOR 3655 Savings potential Heat MWh/a MWh/a 16,7 % /a /a 16,0 % Electricity MWh/a MWh/a 6,8 % /a /a 8,4 % Water m3/a m3/a 7,5 % /a /a 7,5 % Total consumptions Total savings Investments /a /a 11,4 %

9 Total consumptions, energy costs, saving potentials and investments of 388 energy audits in the industry sector with total energy consumption less than 10 GWh/a during the period Present consumption INDUSTRY, Energy consumption < 10 GWh/a 388 Savings potential Heat Electricity Water MWh/a MWh/a 23,7 % /a /a 23,9 % MWh/a MWh/a 7,1 % /a /a 8,6 % m 3 /a m 3 /a 14,9 % /a /a 14,8 % Total consumptions Total savings Investments /a /a 14,3 %

10 Total consumptions, energy costs, saving potentials and investments of 123 energy audits in the industry sector with total energy consumption of GWh/a during the period Present consumption INDUSTRY, Energy consumption GWh/a 123 Savings potential Heat Electricity Water MWh/a MWh/a 22,5 % /a /a 21,2 % MWh/a MWh/a 6,6 % /a /a 7,5 % m 3 /a m 3 /a 10,2 % /a /a 11,2 % Total consumptions Total savings Investments /a /a 12,8 %

11 Average saving potential Service sector Heat 16 % Electricity 7 % Water 8 % SME s with energy use below 70 GWh/a Heat 22 % Electricity 7 % Water 10 % Average saving in energy and water costs 15 % Total payback time for the saving measures is about 2 years 1/3 of the saving potential can be reached by implementing the no cost measures Client questionnaires show that about 2/3 of this potential is implemented in about 2 years after the audit 11

12 Summary figures 1 ( ) Total amount of subsidies 17,3 million service sector 7,5 million non process industry 5,4 million process industry 3,2 million energy sector 0,98 million Number of audits 4800 Coverage Industry: 69 % of electricity use in industry, slightly less in heat and fuels Service sector: 116 million m 3, 48 % of the public building stock of municipalities, 25 % of the building stock in private service sector 12

13 Summary figures 2 ( ) By the end of year 2003 the estimated annual savings in energy and water costs achieved by audits in the service and industry sectors (excluding process industry) is estimated to be some 36 million euros. The corresponding savings in energy use is little over 1 TWh per year. 80 % of the savings come from the industry sector. The cumulative savings during the whole period are approx. 300 million EUR and approximately 8 TWh. The savings in process industry are followed up with the reporting in the energy conservation agreement system. By the end of year 2003 the energy analysis funded by the Ministry of Trade and Industry in process industry have produced annual savings of approximately 0,5 TWh annually and over 2 TWh a year cumulatively. 13

15 Why different Energy Audit Models? An energy audit analyses the present energy use and points out profitable saving measures, but energy is used for different purposes (e.g. heating or process) the scale of energy consumption varies (e.g. school or power plant) the site can be at various stages of its life cycle (e.g. new) the size of the site varies (e.g. petrol station or city hospital) the scope of the energy audit varies (walk through / thorough analysis, system specific / wide scope ) 15 Different needs for amount of work audit phases reporting

16 Energy Audit Models in Finland 1 Service sector Building Energy Audit the basic model for service sector buildings, includes two categories of buildings: simple (schools, offices, etc) and complicated (swimming halls, ice arenas, etc) Energy Inspection the model for small buildings, light reporting Post acceptance Energy Audit the model for new and renovated buildings, tuning the energy use to optimal level Follow up Energy Audit the model to update the previous energy audit In these models the audit cost (and subsidy) are related to the building volume 16

17 Energy Audit Models in Finland 2 Industry Energy Inspection can be applied for extra small SME s Industrial Energy Audit the model for sites with low energy intensive production process, looks at the energy use of the building and the process supply systems Industrial Energy Analysis the heavier model for sites with medium energy intensive production process, includes the process analysis Process Industry Energy Analysis the two phase model for energy intensive process industry, the first step scans the needs for following Industrial Energy Audits and Analyses These models can be used as Follow up Audits also 17 In these models the audit cost (and subsidy) are related to yearly energy and water cost

18 Energy Audit Models in Finland 3 Energy sector District Heating Audit the model for district heating plants and heat distribution networks Power Plant Energy Analysis the model for power plants In these models the audit cost (and subsidy) are related to yearly energy production A model for apartment buildings has been developed, it is in the piloting phase 18
