Task 21 Template for documentation

3. Questions being answered
TASK XXI: Standardisation of Energy Savings Calculations
Questions being answered
Can we define terms in the same way and use the same language?
If this is possible then it will be easier to understand energy savings calculations and to simplify international comparison
Can we agree on how the different approaches for monitoring and verifications are defined and on the key elements that should be included in each approach?

4. Questions being answered (2)
TASK XXI: Standardisation of Energy Savings Calculations
Questions being answered (2)
Will it be possible to group baselines needed to calculate energy efficiency improvements in such a way that projects and governmental/utility programmes can be better compared?
Once we have all these elements, will it be possible to develop common reporting formats to make the verification process less costly?
