Objectives

The main objectives of the Annex are:

  • Establish common calculation methods for SPF using a generalised and transparent approach. The focus is on a fair comparison between different heat pump types, but also for comparison between different competing technologies, such as pellet boilers and gas boilers
  • Establish comprehensive test methods based on further development of existing test standards will be evaluated. The test standards should include test conditions needed for the future SPF calculations.

Project manager and participating countries

Austria, Finland, France, Germany, Japan, The Netherlands, South Korea, Sweden (Operating Agent), Switzerland, and the United States.

Activities

In order to achieve the objectives of the Annex, the following task-sharing activities
have been planned:

Task 1
Survey and Evaluation of existing testing methods and calculation methods for SPF

Task 2
Matrix definition of need for testing and calculation methods

Task 3

New calculation method for SPF/commonly accepted definitions on how SPF is   calculated

Task 4

Identify improvents to existing test procedures

Task 5 

Validation of SPF method

Task 6 
Development of an alternative method to evaluate heat pump performance

Task 7
Communications and stakeholders
