This 2007 document has been developed by the International Energy Agency Renewable Energy Technology Deployment (IEA-RETD). The paper wants to provide a tool â the Standard Methods tool - for policy-makers in order to assist them in determining the adequate level of support in the design of instruments aimed to increase the deployment of renewable heat. The Standard Methods tool focuses in particular on subsidy-based incentive schemes. A calculation methodology has been established to indicate the cost gap between conventional fuel heating technologies and solar thermal heating technologies.
The calculation methodology includes investment costs and running costs. The tool compiles national data among nine countries by which the cost gap of heat generation costs between active solar thermal heating and conventional heating technologies is estimated.
