[Equest-users] In Appendix G comparisons are air side economizers required in IDF/Electrical Rooms

[Jansen, Connor]

Hello All,

 

When performing a 90.1 2007 Appendix G energy model, the baseline system
for the building appears to call for a packaged single zone air handler
and an airside economizer for individual IDF and Electrical rooms. The
proposed systems are designed as FCUs. Although not addressed in
Appendix G, section 6.5.1, would appear to exempt the airside
economizers in rooms requiring a low cooling capacity. 

 

With that said, is it correct to reference other parts of ASHRAE 90.1
(prescriptive path Sec 6.5) when performing a performance based Appendix
G energy cost comparison?

 

Your help and clarification would be much appreciated. I apologize if
this is not the correct forum for this post and would be greatly obliged
if you were to direct me to the correct forum.

 

Regards,

 

Connor
