Industrial or non-regular process load

Some of the guidance is concrete and some not so much. If you can point to some sort of standard it is clear - say boiler efficiency for a process boiler you can point to 90.1. This could apply to motors, chillers, etc. For specialty equipment the baseline is standard industry practice in that area. This gets harder to define. So you have to do the research to justify the baseline. There is just so many different specialize process equipment that it would be extremely difficult to create a baseline for each.These types of facilities need to do an exceptional calculation to show enough savings. I think that the documentation methods in that interpretation would still apply to v4.

Does anybody have news about interpetation update for v4 NC or other information how to deal with process load ?  We have high process energy loads (about 70% from total) in our industrial building project.

LI #10493 relaxes the percent reduction per LEED point for such facilities.  Recovery from air compressors, stack economizers, ultra-high efficient motors. Do not spec electric boilers. Spec gas equipment that is 90% efficient.  turn off / turn down equipment when not in use. (VFDs) Recover / Reclaim energy every chance you get. .....and Best of Luck with results from the eneryg model! most all my projects are international factories, above is the speech i give when kicking off the project.

Hi Everyone do we need to perform "exceptional Load Calculations"?  in case the simulation software such as HAP-V6 have an option to perform the "process load load calculations. LI-10291 rulling recomends to perform both calculation with Process load and with-out process load, it seems vague. 1-If yes, how can we earn the points? 2-Ashrae Regulated Loads fotors are based on 60Hz frequency, can we consider 50 Hz motors as Non-Regulated Load? 3- LI#10291 and LI# 10493 both are slighty different for process load points earning, is it true?

Hi  what is the procedure to claculate "Exceptional Process load" and Savings? 1--Some sfoftware such as HAP-V6 can calculate the process load with respect to schedules, so we still need to calcuate the "exceptional Load" separately? 2--Li# 10291 recomends to simulate both with process load and without proccess loads, i cant understand the interpretation and have the confusion, how to calculate the SAVING to earn points? 3--Li# 10493 recommends to earn points in Core n Shell catagory, as i understand. Simulate the project and claim the saving in category core n Shell(CS) instead on New Construction, it is correct understanding? 4--Ashrae table for motor mentioned 60 Hz motors, Can we consider 50 Hz motors as non-regulated load? I need to understand the rightway or the approperiate way to earn credits/points for an industrial project with "High-Process load.  

Process load savings follow the exceptional calculation method. Basically you do your models with baseline process loads identical to the proposed model. The proposed model for process loads should be an accurate reflection of the energy use of the proposed systems, especially those systems for which you will claim savings. You then provide a narrative explanation for how you are modeling or otherwise calculating the savings describing the systems in question. You then will need to provide a justification for a modified baseline to show the savings. The baseline should be based on common practice for that system in your particular area. This is often the hardest part for modelers to grasp but it is the most impiortant. You must justify your savings by justifying the baseline selected as being common practice so what you are doing in the proposed should be uncommon practice for those systems in your area. So exceptional calculations are easy to find baselines others are significantly more difficult. You whould look for standards documents like 90.1 or COMNET to help define some baselines. For others you might look to untility rebate programs in your area if they exist.  LI 10291 does not apply to LEED v4 projects. LI 10493 simply allows high process load facilities to use CS thresholds instead of the NC thresholds. The frequency of the motors does not matter. It is the use of the motors that determines if it is a process load or not.

Thanks Marcus can you give few TIPS to create a BASELINE for manufacturing process??? particulary, it is leather gloves manufacturing and so far no other Factory has LEED certified(one is in progress). so it is very hard to explore the baseline, however, standard practice is know but not documented.   We have more then 65% Prcoess load in SHAPE of Motors and 5% of that are Elecctric resisitan heating for Leather Embosing.  Let me correct, if the MOTORS are using for PROCESS load, we may consider it Non-Regulated Load?  HAP new version (V6 3D) can calcultae the process load with schedule, Do we still need to perform the exceptional calculations? if yes, it there any format/equitions/methods to perform? i have no clue , how to perform the calculation. Please guide  

Non-regulated loads are the same thing as a process load. Let me give you a simple baseline example. For the process motors if you use premium efficiency motors instand of standard efficiency motors you can claim savings. Standard efficiency motors are well documented and you can easily show the baseline. So if standard practice is known then it is up to you to convince the reviewer that you know what it is. Back up documentation is helpful but in very specific cases it is often not "documented". What are you doing in this particular factory that is more energy efficient than standard practice? Did you change anything about the manufacturing process to gain efficiency? In the case of specific manufacturing processes it is incumbent upon you to figure out how to do it and how to document it as each such manufacturing process is unique. Regarding calculations it requires engineering expertise. I can't give you that in a LEED User post. Such calculations are not aften found within energy modeling software and require the use of calculations outside the software. Again you will have to  demonstrate your calculations to the reviewer to justify the savings you are claiming.  I am getting the feeling that you are in over your head. There is no easy way to figure this out without having considerable experience in industrial engineering and how to calculate energy savings for a wide spectrum of energy efficiency measures.

Marcus your contibution is impressive, i have no words to appreciate and Thanks.  

Thank you so much Marcus
