NC-2009 EAp2:Minimum Energy Performance

Hi all,

I am working on a certification for a factory having less than 5 percent conditioned area. My process load is also high upto 75 percent. Can any one suggest me how to get savings in optimize energy performance. is there any exceptional methods to show savings. Thanks.

Sounds like you will need to show process energy savings. To do so you will need to perform exceptional calculations. The method will vary depending on the energy saving measure. Often the hardest part is establishing the baseline for comparison. What kind of factory is it? What are the biggest process energy users?

Thanks for your reply Marcus. It is a garment factory with all kind of sewing and cutting machines having accounting the most process energy. All working areas except office is mechanically ventilated with blower fans. Can you help with what kind of savings can I claim.

I am not familiar with energy saving strategies related to that equipment. I would talk to the manufacturers of the equipment to see if they had any ideas. Your baseline will be what is standard practice in this area when building a new factory. Then you will need to identify strategies to exceed it.
