In order to accomplish the stated goal and objectives, the Participants carried out research in the framework of two Subtasks during the initial phase of the Task:

• Subtask A: Tool Evaluation
• Subtask B: Model Documentation

During a Task Extension Phase, the Participants focused on two new Subtasks:

• Subtask C: Comparative Evaluation
• Subtask D: Empirical Validation

Subtask C: Comparative Evaluation

In Subtask C, the Participants worked to:

• Establish an overall building energy analysis tool diagnostic framework.
• Identify reasonable set of test cases.
• Prepare preliminary test case specifications.
• Apply building energy analysis tools to test cases.
• Revise/finalize test case specifications.
• Iterate with building energy analysis tools as appropriate and required to obtain valid results.
• Finalize results.
• Prepare documentation of test cases/results. Þ
• Place test specifications and results on IEA SHC web site.

Subtask D: Empirical Validation

In Subtask D, the Participants worked to:

• Establish an overall experimental framework.
• Identify reasonable set of experiments to evaluate the modeling capability and accuracy of building energy analysis tools.
• Conduct experiments.
• Apply building energy analysis tools to model experimental conditions.
• Revise experimental conditions to obtain necessary quality of data.
• Iterate as necessary between modeling and experiments to obtain valid empirical tests.
• Prepare documentation of experiments and results.
• Place data and results on IEA SHC web site.
