klima:aktiv • Active climate protection initiative• Launched in 2004 by the Federal Ministry of Agriculture, Forestry, Environment and Water Management

• Emissions must be reduced from 78.9 million tonnes CO2 equivalent (base year: 1990) to 68.7 million tonnes by the period of 2008-2012

klima:aktiv goals• Lower carbon dioxide emissions through higher energy efficiency• Increased use of renewable energy sources in all climate relevant areas of life• Meeting the Kyoto targets• Stimulating the climate protection markets• Creating a strong home market• New jobs are created and secured in the climate relevant industries• Strengthening Austria’s position as a business location in the long term

12

Main technical deficiencies• The heat demand of the consumers is over estimated• Over estimated reserve capacity stored in the heating plant• The pipeline grid system is over dimensioned• Size of the fuel silo is bigger than required• Low utilisation ratio of the wood boiler• Fuel quality does not meet the quality requirements for the installed firing• Faults in the hydraulic and in the control system lead to high operation costs

could have been avoided with professional planning !

Also professional management in organisation, finance, marketing are essential.

15

The objective of the tool „QA Wood Combustion“ is to ensure, that plants are built with• High technical and operational performance• High utilisation ratio• Low emission• Low investment costs• Low operation costs

qm heizwerke - goals• Optimized design engineering process• More efficient biomass district heating plants• Know-How exchange• CO2 – Reduction• Feedback for subsidising authorities.• International co-operations for more dissemination of biomass district heating plants

16

Assurance of the Technical Quality

Q-Guideline (Q-Leitfaden)

• 45 single requirements are defined

The requirements define the best available technologyin the areas:

• Analysis of initial situation• Heat production• Heat supply• Documentation• Acceptance procedure• Optimisation of the plant operation• Final verification

17

some criteria• network heat utilisation ratio [kWh/m] at least 900, target > 1.200• network heat losses < 20 % • temperature differential feed / return [C] at least > 30°, target > 40°• boiler full load operating hours [hr]• specific electricity consumption [kWhel / MWhth]• specific invest costs heating network [€/MWh a]• specific invest costs heat plant [€/kW]• . . .

• boiler house equipment• minimum requirement of measurement instrumentation

18

• The “Q-Plan” is a tool to stipulate the quality for each specific plant.• After commissioning the functionality and the recorded operation data must be verified by analysis.

Assurance of the Technical Quality

“Q-Plan” - Quality Control Plan

19

• Summarizes operation data after the end of the qm process

• The same versionfor all federal states of Austria

• Upload via XML-Format• Benchmarking is made possible.

Definition, Characteristics

energy service, aims to improve the efficiency in energy production (and energy consumption)

Contracting ist eine intelligente Lösung für die Energieversorgung Ihrer Gebäude.

Contractorplanning, financing, construction and operation

of the plant to supply energy to buildings & processes (z.B. wood chip plant, pellets plant, …)

Energy-supply-contracting

energy supply can include: heat, cold, steam, electricity, compressed air

planning, financing, construction and operationis done by the contractor

the contractor hires the room or lot of landhe needs to build the plant from the customer

the customer does not buy the plant (technical equipment),but he draws the energy he needs from the contractor.

the contractor is owner of the plant (technical equipment)

jointly the details of the agreement are defined in the energy supply contract

the total price for the energy supply consists of a basic rate [€/month], an energy rate [€/kWh], and an meter charge [€/yr]
