Summarize multiple table with dax

Hi , chrisyan_manalu 

According to your description, you want to get the table like this:

But in the 'FactChiller' table it has five 'hc001' in it. I am not fully understand your logic to get this table. And how the [Year] is determined?(In your expeted table , you have only three rows.)Can you explain your logic to get this table?

Secondly, you have 4 tables, can you provide the relationship established between the following 4 tables?

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI! 

Best Regards,

Aniya Zhang
