EnergyPlus Support,
Hi,
My name is Márcia, and I would like to ask somethings about E+.
 I have been working with this software and at this moment I need to do a lot of parametric variations. I don´t know if is possible to do all parametric variations using E+, I wouldn´t like to make the variations/changes one by one. Or whether, it is possible give to the program E + the desire instructions  about parametric variations and obtain all files with the changes (changes automatically generated by E +, not for me one by one). 
For example: 
  - I want change the number of air changes per hour in 0.5, 1, 2, 3 and 4 RPH in a file with basic geometry and other objects already defined. How can I make these changes or others that I want, without introducing or modifying the parameter one by one? 
Sorry if I was unable to explain my question clearly. 
Grateful for the attention. 
Best regards, 
Márcia T.
