EAp2 requires that 50% (by power rating) of new equipment and appliances purchase for the LEED-CI scope of work be Energy Star labeled. Projects that go beyond the 50% requirement can achieve up to four additional points under EAc1.4 by specifying 70%, 77%, 84%, or 90% Energy Star equipment.
Completing the rated powerRated power is the nameplate power on a piece of equipment. It represents the capacity of the unit and is the maximum that it will draw. listing for each appliance and piece of equipment is the most time-consuming part of this credit. The LEED documentation requires not just checking a box to confirm that equipment is Energy Star; you will also need to assign a rated power to each model of appliance, computer, monitors, etc., which sometimes requires pulling the specification sheet or looking on the device’s nameplate.
In the past GBCI has allowed a shortcut: you could use standard rated power values from Table 2 in the LEED Reference Guide, but LEEDuser has found that this is no longer allowed.
Rated power is not the amount of power a piece of equipment will actually use, but simply the “nameplate power.” It represents the capacity of the unit and is the maximum that it will draw. The actual power used by equipment or appliances is often less than half the rated power. Rated power is what you have to use for the calculations for this credit.
Calculations for achieving this credit have to include all of the following, provided they are available in an Energy Star labeled model and are in your project's scope of work to purchase or install new:
If an entire product type is not Energy Star labeled, that equipment is excluded from your calculations. Conversely, equipment outside the four categories that is Energy Star labeled must be included in your calculations. HVAC, lighting, and building envelope products are excluded from calculations for this credit.
Any categories added to the Energy Star list as the program grows may be used in the project team’s calculation. You can check out the Energy Star website for updates to product categories.
When LEED 2009 was released in June 2009, the LEED Reference Guide described this credit as referring to all equipment used on the project, whether new or existing. However, as clarified in the April 2010 LEED addenda from USGBC, the credit is only applicable to equipment installed or purchased new for the scope of work covered by the LEED-CI project. This clarification, which also applies to EAp2 means that project teams have neither an incentive or a disincentive to replace older equipment. Teams may choose to purchase newer, more efficient equipment, or preserve older equipment that still has useful life.
Projects still may include used equipment in their credit documentation, but if they do, they must include all the older equipment being used, not just some of it.
For all questions related to qualifying Energy Star equipment, please refer to the Energy Star website products section.
Details for each qualifying product are given in specifications on the Energy Star website under each product category. If your equipment type is not eligible for Energy Star, you should be able to exclude it from your calculations. However, make sure the product type is actually not eligible if you are excluding it from the calculations. If there just aren’t enough models on the market yet, but the product is eligible, you have to include it in your calculations.
First identify which appliances and equipment are eligible for an Energy Star rating in your project. Check the Energy Star website for up-to-date listings of products and appliances that are available as Energy Star-labeled and create a project-specific list of these items. At minimum, the equipment list will include office equipment such as computers, fax machines, printers, scanners, multi-function devices, and monitors, as well as appliances such as refrigerators, dishwashers, washers and dryers, etc. (See the LEED Reference Guide EAc1.4, Table 2 for the minimum category of appliances to be included.)
Your list has to include only equipment that is installed new or purchased within the LEED-CI project scope; existing equipment may be excluded (note that this is a change from the original 2009 release of the rating system—see the Bird's Eye View for more detail).
HVAC, lighting, and building envelope products are excluded from calculations for this credit.
There are new equipment types earning the Energy Star label on a regular basis. Any equipment type that fits into the LEED categories for equipment addressed by the credit should be included in credit calculations.
Be sure to refer to the Energy Star website on a regular basis as the website is updated several times a year.
Add the rated power of all equipment and the rated power of Energy Star labeled equipment for your project to your equipment list. The rated power is usually imprinted on the equipment (in watts or kilowatts, i.e., kW) or you can use the standard values in the LEED Reference Guide, EAc1.4 Table 2 for equipment and appliances listed there.
The rated power can also be derived from listed ratings in volts and amps, which you multiply to obtain watts. Use the equation Watts = Amps x Volts.
Sum the two columns and calculate the percentage of rated power that comes from Energy Star labeled equipment. It has to be at least 50% of total project equipment rated power to achieve the prerequisite, and 70%, 77%, 84%, and 90% for 1-4 points.
If an Energy Star product is purchased as a replacement for older, less efficient equipment, you can assign it the higher rated power of the original product for the purposes of your calculation. Doing that gives these replacement products more weight in the calculations. The replacement must be purchased between project registration and when the project is submitted for certification.
Identify and prioritize the equipment with the highest rated power, because those are the items that will help you most. Your credit calculations will be based on the rated power of the equipment, not the number of individual Energy Star labeled machines. For example, the rated power of a copier is much higher than a laptop. If you buy only one of each, an Energy Star labeled copier will contribute more to the overall Energy Star labeled power percentage.
Performing your calculations early on will tell you if the project owner needs to specify more Energy Star labeled equipment for the new spaces.
In most product categories there is a wide range of Energy Star labeled products to choose from. Energy Star sets a minimum performance level, but some options are more efficient than others. As much as possible, choose the most efficient equipment. If doing that means getting equipment with a lower power rating, use the power rating from the LEED Reference Guide or from older equipment you are replacing to avoid being penalized in the credit calculation.
If used equipment was labeled Energy Star at the time it was purchased, but is not in the current list anymore, it can be listed as an Energy Star product. However, all new products purchased at the time of construction should be Energy Star labeled.
Most Energy Star office computers and equipment carry little or no cost premium, and bring operational cost savings.
Involve the facilities manager, operations personnel or procurement staff in conversations about energy-efficient equipment. They should be able to provide a list of specified and existing equipment to help with your calculations.
You can get a bonus by claiming the original power consumption of the piece of equipment that is being upgraded to more efficient Energy Star equipment.
It is no longer required to track existing reused equipment. Refer to the following LEED Addendum posted on 4/16/10. “Only new appliances and equipment purchased as part of the scope of work for the project need to be included in the credit for EA Credit 1.4. Equipment and appliances must meet the Energy Star criteria current at the time of purchase. Any items that are purchased after the item's category has become ENERGY STAR eligible must meet the Energy Star rating. Any items already covered by the ENERGY STAR program that are purchased after new criteria have been issued must meet the new criteria. Items purchased before the category is ENERGY STAR eligible do not need to meet the ENERGY STAR rating; similarly, items purchased before new criteria are issued do not need to meet the new criteria.”
Energy Star labels are not permanent, and Energy Star criteria get stricter over time. If your piece of equipment no longer has an Energy Star label, but you can prove that it did when you bought it, you can still count it.
Make sure to update your Energy Star list with all known appliances and equipment included in the project, with associated rated power for each and indicate whether it is Energy Star labeled. Sum the rated power of your equipment list, including Energy Star labeled equipment.
Not all products need to be Energy Star labeled to get the credit, you just need to reach your chosen threshold of Energy Star labeled equipment for your project: 70%, 77%, 84%, or 90% for 1-4 points.
Check the Energy Star website to update your list of appliances and equipment that must be Energy Star labeled to make sure that all have been accounted for.
To meet the next point threshold, identify power-hungry appliances that are in need of replacement within the next year, like copiers, printers, and refrigerators and target them for replacement or efficiency upgrade before project completion.
Note that Energy Star rates the power usage of “sleep,” “standby,” and “hibernate” modes for computers, which may be lower than the computer’s power rating. Use the rated power for the active mode and be consistent in your documentation.
Establish an Energy Star purchasing policy for all future equipment. Although a purchasing policy is not required to earn this credit, it can help ensure that the project continues efforts to achieve cost-effective energy conservation.
Once the construction documents are complete, update your equipment list to track any changes and confirm that specified equipment is included in final construction documents.
Complete your documentation on LEED Online. List each piece of equipment, with its rated power, and indicate if it is Energy Star labeled. The calculator built in to LEED Online automatically sums up the eligible wattage to confirm compliance and points achieved. If you prefer, you can upload your list, as long as it is in spreadsheet form and calculates the Energy Star labeled power percentage properly.
Purchase new equipment and appliances that are Energy Star labeled, to the greatest extent possible.
See the Operations and Maintenance section of the Reference Guide or LEED-EBOM for guidance on continued purchasing and replacement of Energy Star equipment after initial project specification. Work this guidance into procurement policies for future purchases.

Complete documentation for achievement of EAc1.4 on a LEED-CI 2009 project.
We are going to purchase a new Energy Star-Labeled TV for the office. We can find TVs available as Energy Star-qualified in the categories shown in the Energy Star website. However, the Energy Star program of Japan only approves the equipment related to PCs such as computers, monitors, printers and like that. It seems that TVs are outside the scope of the target products in Japan.
We are not sure whether or not we can include it in the calculation under such conditions. Even if choosing to purchase a Energy Star one, are we not able to earn points under EAc1.4 (as well as EAp2), not complying with the local regulation?
Thank you in advance.
Good question. While I'm a commercial kitchen equipment person not TV, the way I've seen it work is regardless of whether E/S is recognized or to what degree, in another country, the 'intent' is to meet or exceed the Energy Star published baselines for the appliance. The E/S standards do have power consumption limits based on various modes of operation, so it seems to me that a TV that meets/exceeds should count in the rated powerRated power is the nameplate power on a piece of equipment. It represents the capacity of the unit and is the maximum that it will draw. calcs. Here is a link to the Version 6.0 DRAFT version, and underneath info on Ver. 4 & 5. Noticed that there is also a "most efficient" distinction coming around too. Hope it helps.
Thank you very much for giving us helpful advice. I am sorry if my understanding is wrong, but is it acceptable to choose energy efficient products (not Energy Star labeled ones) as long as they meet or exceed the Energy Star published baselines and prove to be equivalent to the baselines or more?
Thank you in advance again.
I have two questions regarding the inclusion of UPS in the 'Energy Star' calculation for EAc1.4 in LEED v2009.
Q1. To Include UPS or not for Energy Star calculation?
I understand that ENERGY STAR rated appliances purchased prior to the publication of the current ‘criteria’ and complying with the previous criteria can meet the intent and requirements of LEED-CI EAc1.4… and that all equipment purchased after the new ‘criteria’ have been issued need to meet the new specification.
For example, Refrigerator was a ‘category’ in Energy Star when LEEDv2009 was released… and new ‘criteria’ has been published in Energy Star.
However, my question is regarding the language on p180 that states… "Any new ‘categories’ added to the Energy Star list in future may (not MUST) be used in the project team’s calculation’.
Since UPS was NOT a ‘category’ listed in Energy Star when LEEDv2009 was released... I would assume that the project team can choose to include the UPS or not based on the guidance given in the sentence above.
Is that correct?
Note, we've NOT included UPS in recent submissions and have never been queried in the Review!?
Q2. What is the ‘Rated Power’ for a UPS?
Notwithstanding the above... IF it is required to include the UPS in the Energy Star calculation... then what is the correct 'Rated Power' for inclusion in the LEED Online table?
The UPS mostly stands idle... but (potentially) has a huge 'Output Rated Power' say 200,000 Watts for a short period of time from the battery back-up power… while the maximum power drawn by the UPS is a much lower number... say 2,000 Watts!
My understanding is that we would use the maximum 'draw power' of the UPS rather than the maximum 'power output' of the UPS for input to the Energy Star calculation.
Is that correct?
Thanks in advance... Any advice is much appreciated.
Q1: I think that "category" is not referring to a specific product. UPS is a product under the Office Equipment category so I do not think the sentence you quote applies. The Reference Guide clearly states on page 180 as well that "The credit applies to all installed equipment and appliances listed by the Energy Star program."
In these situations the general practice is to require project teams to follow the guidance in place when the project was registered. So if your project was registered before this product was included in ES then I would say you do not have to include it. Also note that previous reviews do not establish precedence.
Q2: That would make sense to me.
Are CPU's also need to qualify Energy Star rating? In my case, monitors have Energy Star label.
Yes computers are Energy Star rated.
Hi Marcus, in your above response, by computers do you mean monitors and CPUs have to separately Energy Star rated?
Yes they are rated separately.
Do domestic hot water heaters fall into this category? They aren't listed in the reference manual, nor can I find mention of them on this site. Energy Star does have a bunch of rated models, but only for gas or propane. The few electric models they have rated are only 50 gallons or larger. Can hot water heaters be excluded from these calcs altogether, and furthermore do they belong in calcs for EAc1.3 instead?
This credit specifically excludes hot water heaters because they fall under "regulated," even though there is an Energy Star rating and most Energy Star appliances are 'process.' The key with Energy Star is not to look for the actual listing but the STANDARD, then compare the standard against what you are specifying. Does that help? Here's a link to the standard. http://www.energystar.gov/index.cfm?c=water_heat.pr_crit_water_heaters
If the answer is "yes, they are excluded," then yes, thank you!
I do see the distinction between regulated and process load in table 1, but it wasn't clear to me elsewhere in the section where the distinction was made, and the only CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide I could find on the topic was from way back in 2009 before water heaters were even rated in Energy Star. Do you have a source for this answer? Thanks!
What is the difference between regulated loads within offices and unregulated process loads ?
Regulated loads are ones covered by 90.1 (envelope, lighting, motors, HVAC, hot water, etc.). Unregulated process loads are items not covered by 90.1.
Of note, under LEED V4, process loads have more impact in all tracks as opposed to only Retail/Hospitality/ID&C. Simplest way to help clients understand this is that the "process" is case-specific and normally doesn't run 24/7, like commercial cooking & warewashing equipment, as well as office equipment. But if the building was a frozen food warehouse, process loads would likely be the largest impact on the project. However, in the case of commercial ware washing, water usage of that piece can affect the (regulated) hot water heater sizing since it has to supply incoming water at usually 110 degrees & up. Here is a link to the specifics about hot water heaters and Energy Star standards.
Would anyone know if production lighting (for video conferencing spaces) would have to be included under this credit (EAc1.4 - OEP equipment and appliances)? Or should it be considered under the lighting credits? They would only be used sporadically.
Under the lighting credits. It's possible that this type of lighting would be exempt from the lighting power density calculations. See section 126.96.36.199 Interior Lighting Power in ASHRAE 90.1-2007.
Has anyone ever used local equivalents instead of the Energy Star rating?
ID#1492 states that we can use local equivalents.
The EU energy rating is the local standard here whereby equipments are rated by A++, A+, A, B, C ... How can we determine which rating would GBCI deem equivalent to Energy Star?
I don't know, but perhaps this might help: Energy Star aims to capture about 20% of the market in a certain product area. If more than 50% of the market starts to be compliant with Energy Star, the program raises the bar. Perhaps this rough benchmark of the Energy Star mission, along with specifications on specific equipment that you are looking at, could be helpful.
Hi, in relation to the point discussed above I have a query. We are doing a project in India and most of the products available there are BEE Star Rated, an energy efficiency rating standard implemented by the Indian government. Wanted to know how can BEE star rating be compared with the Energy Star rating and how to document these products?
I would create a table that contains the Energy Star, BEE Star and actual kWhA kilowatt-hour is a unit of work or energy, measured as 1 kilowatt (1,000 watts) of power expended for 1 hour. One kWh is equivalent to 3,412 Btu./year value for each applicable item to enable a comparison. I would also reach out to the BEE Star folks to see if they could help you with a comparison.
Consortium for Energy Efficiency has Energy Star & standards information. PLEASE keep in mind that for some products, PART of Energy Star pertains to water usage too, since you are paying to heat or cool water with some appliances. Therefore, you may find what you need here:
You didn't say what the product category is, but if it is commercial kitchen equipment, Kim Erickson is a wonderful resource there. Also if commercial kitchen equipment, go to fishnick.com and look for the .xls LEED Prescriptive Measures. Hope it helps.
Hi, Would you clarify if routers and switches should be included in the list?
My understanding is no. The best place to check is on the Energy Star.gov website under Business and Commercial products. If you click on the category and then on the small hyperlink "For Partners" you get the definition document. Make sure you scroll all the way down to Item 2 to see what is excluded before you examine the Item 1 definitions. Sometimes lots is actually excluded.
Good morning Susan,
F.Y.I. The small network equipment category was added under the "For Your Home" tab with an effective date on September 3, 2013. The small network equipment category includes routers, switches and other equipment. I am not sure if this is applicable to commercial project but thought I would share what I found. See link below for additional information:
We are compiling the equipment for a multi-floor office renovation. Dow e need to include A/V Equipment? Including ceiling speakers, projectors, projection screens, microphones, etc?
We've done several projects with AV equipment. Per the Energy Star programming document for AV, the display elements are the focus of the eligible equipment, i.e., the monitors and TVs. And of course any CPUs that are running things.
Explicity excluded are projectors, battery powered portables, video conferencing, wireless microphones, and whole house audio or video and media servers.
Just a brief addition to Michelle's note- BKSK be sure the AV consultant/vendor is aware that the ENERGY STAR evaluation (and specs to include ENERGY STAR whenever possible) applies to the following in addition to displays (TV screens):
MP3 speaker docks
Blu-ray Disc players
Does anyone know what the rated powerRated power is the nameplate power on a piece of equipment. It represents the capacity of the unit and is the maximum that it will draw. is for vending machines?
Check out the Energy Star website to download the spreadsheet to find the model # and corresponding rated powerRated power is the nameplate power on a piece of equipment. It represents the capacity of the unit and is the maximum that it will draw.
A great spreadsheet to have on hand is this one, which is the LEED Prescriptive Baselines for water and energy because it shows qualifying equipment with standards other than Energy Star. As commercial kitchen equipment plays a more important role, it has gotten a lot bigger. LEED for Retail has an excerpt from this and Richard Young at Fisher Nickel is on the committee.
For context, the ENERGY STAR website indicates that this category currently only applies to new and rebuilt refrigerated beverage machines. So, exclude food/snack machines from your evaluation.
Generally the rated powerRated power is the nameplate power on a piece of equipment. It represents the capacity of the unit and is the maximum that it will draw. is considered the maximum electrical/energy "draw" an equipment item can use. You'll need to locate the specific vending machines data...either a cutsheet or perhaps webpage listing technical data- if the specified unit's wattage isn't listed, you can determine it using the following: (watts = amps x volts). Be sure the use the voltage specified for the electrical design....or you could use the highest allowable voltage configuration listed on the equipment cutsheet as a "worst case".
Where in the 2009 CI LEED reference guide does it state that only NEW Energy Star appliances are to be included in the calculations? I see you all note that new equpment only is what is supposed to be included in the paragraph above and in comments, but I seem to be missing it in the LEED reference guide.
For example ... I have a client who is relocating all of their printers, monitors, laptops and desktops. Therefore the only new equipment are appliances and TVs. So all I would include are the appliances and TVs?
Please confirm. I just want to make sure I am understanding correctly.
Yes, Energy Star only applies to "new" and "eligible" pieces of equipment. Relocated equipment is excluded, so yes only include TVs and appliances and makes sure you explain in Special Circumstances that the office equipment is relocated.
Look at the 4/16/2010 addendum to see where this is stated. It's very difficult to keep up with all the ever changing requirements. You'll need to watch quarterly addenda in addition to CIRs and on-line credit forms to capture all the nuances. Unfortunately, you cannot rely on the reference manual to contain everything anymore. It's a continuing lament.
Thank you so much! This is exaclty what I needed and was searching everywhere for. Looks like I need to catch up on my addenda ...
We run into this all the time with commercial kitchen equipment. Schools take very good care of their equipment, as an example, so there's potentially a lot of "existing, relocate'. But the consequences real world can be wicked if the actuals are far from the models. And they could be with dishwashers and ice makers because the water and energy has dropped so drastically. Utilities often give rebates on both so an energy audit factoring that in might be prudent. Then, use the template to calculate.
I hate to be dense but ours is a small office remodel, and there are only three pieces of equipment bought FOR the remodel a refrigerator, a TV, and a dishwasher all energy star compliant therefore we are 100% compliant four points! & an EP! - but that hardly seems right. What am I missing?
I say FOR the remodel, because it's been going on for a year and some new PC's have been bought that would have been needed anyway; I could include them I guess, but it doesn't change the strange total compliance.
Yes, it is what you buy, not what you use. But if I recall correctly, if the PC's used are within a year old, they count. Don't forget copiers, printers, monitors, routers, servers, various phone systems, & modems. Since smaller offices often use "residential" products, the "oh yeah" list can be found here, & USGBC statement below that, which is good since while there are Energy Star light strips, air conditioners, etc., they don't apply here. Hope it helps!
I am trying to determine if we need to include " No-break (UPS - Uninterruptible Power Supplies) " in our Energy Star documentation for this credit.
Hi Vitorio- Any luck on this?
I thought I recalled an GBCI issued addenda that stated new categories were to be included in the same general categories already required for evaluation (Office equipment, food service, etc) but cannot locate it....may be falsely remembering that. UPS and Enterprise servers are both new categories under "Computers" in the ENERGY STAR website, which is part of a broad classification of "Office Equipment" so I would expect they need to be included in LEED calcs. They can represent a LOT of wattage so best to catch them and ensure they are ENERGY STAR rated in the planning/specifications stages of a project.
I am not sure if this is still a question or condfusion in LEED User but it does crop up on current projects.
Making reference to LEED Reference Guide for Green Interior Design and Construction with Global ACPs p30 in the table under "The following equipment is included in the scope and must be accounted for in the credit calculation:" UPS is not listed under Computers and Electronics!
I assume the logic is that a UPS conditions power supply, and only energy consumed is the energy associated with losses. E.g. a 100 kVA @ 0.8 pf iand 95% efficient consumes only 4 kW, not 80 kW.
John, I can't find your reference above. Page 30 in the ID+C Reference Guide falls within SSc1. Page 30 in the ID+C Rating System is MRc2. In any case I do not think that because it is not on a list means that it is not included.
UPS falls under office equipment within Energy Star and the Reference Guide and Rating System documents clearly state that all Energy Star eligible equipment is included within EAp2 and EAc1.4.
My client is thinking of renting a vending machine for his office pursuing LEED-CI certification. Would we have to include the vending machine in the calculations even though vending machines don't fall under any of the Energy Star categories specified for this credit (appliances, office equipment, electronics, commercial food service equipment)?
Also, I don´t know if the fact that the vending machine is being rented makes a any difference? Technically, it is not being purchased or installed new within the LEED-CI project scope.
Thanks for your help!
Yes, you are obliged to include all eligible equipment in this credit. Vending machines are eligible for Energy Star rating. The "new" part is an issue but not with respect to leasing, only with respect to re-using. In other words, leased equipment is included as if it's newly purchased. Only eligible equipment moved from another location for reuse can be excluded.
I concur with Michelle, as I've always included vending machines whenever they're within the project scope whether purchased or leased. The following is a link to more information about Energy Star for vending machines:
The following is a link to a listing of all ES qualified vending machines:
Hope that helps. If your client hasn't already rented the machine, they can always make Energy Star a requirement of the rental agreement - just a thought.
Just one more question: According to the document "Vending Machines Program Requirements Version 3.0" developed by Energy Star, only products that meet the definition of a Refrigerated Beverage Vending Machine as specified in such document are eligible for ENERGY STAR qualification.
Does this mean that if my client is leasing a vending machine for snacks (i.e. non-refrigerated, non-‘‘sealed beverage’’ merchandise), it does not have to be included in the calculations for this credit?
Yes, your vending machine would be excluded from the refigerated beverage requirements. You should plan to explain that in the Special Circumstances so the reviewers know you didn't miss it or fail to include it as eligible.
As we all know, our Energy Star requirement is based on the eligibility of the equipment for rating and that eligibility is defined by Energy Star not by the USGBC. If a general category is not rated, like microwaves or ranges, things are fairly straightforward.
If the definition found in the Program Requirements document clearly excludes the equipment, like monitors over 65" or combi ovens with steam, then things remain straightforward. However, plan on uploading your excluded equipment cutsheet and definition to confirm this for the reviewer.
We recently, however, saw a piece of equipment that couldn't be easily excluded based on the program definition. These electric Panini grills seemed to meet the definition for griddles, i.e., two platens, grooved or smooth, contact cooking, thermostat, etc. When we reviewed the products that were rated, however, we noted that the scale of the equipment rated was very different than our equipment. Asking the manufacturer often results in the answer that best suits their sale of the equipment, so we went to Energy Star.
I am posting this because when I made contact with Energy Star to ask the simple question were these grills eligible, the answer was very tough to get. The first line of response was "this equipment isn't rated because the manufacturer hasn't partnered with us". I clarified that I knew they weren't rated but were they eligible. The next response was that "it's up to the manufacturer to determine that". Obviously that would be a fox and henhouse scenario for this kind of situation.
Ultimately, I had to track down the third party company that is doing the responses for Energy Star and call them on the phone. Once I was able to make clear what I needed to know, I got a rather reluctant response from a tech person via email that "the intent of the program definition" was in fact larger, free standing equipment vs. the countertop device I am looking at.
This may sound ridiculous but these 2 electric Panini grills drew so much power, compared to the more efficient larger equipment, that they took a 100% Energy Star result worth 5 pts down to 54% or barely making the Prereq.
We have excluded this equipment based on the "intent" of the program definition as the USBGC has always recognized intent. However, I was personally disheartened at how hard it was to get this answer and how hard it was to explain what I was asking. There are certainly pros and cons to LEED piggybacking on other organization's standards.
Very interesting, Michelle.
I am in the food service industry. An Energy Star partner manufacturer agrees to provide E/S with shipment data per sku each year as only the top 20% of appliances are supposed to make the list. Sometimes that criteria is a bit odd, such as a reach in refrigerator being judged with door closed when it opens 50 times/day. But manufacturer partners agree on how it should be judged. Like a swimsuit competition where contestants agree it's all one piece.
A panini is not a "griddle" or grill. In fact, it doesn't typically go under a hood unless one is actually "grilling" grease-laden product, and panini's are most frequently considered/called "sandwich presses," where speed is favored and some are self-serve. Plus, when called a "press", it takes them out of the grill/griddle/hood-requiring category. Yep, they use a lot of energy, as do the merchandisers ice cream novelty providers give for free, where there is no E/S category. BUT, where the whole griddle/panini kind of blows up is that there are ventilation/capture-containment, heat gain elements that are NOT considered! In many cases, those are the big get. Griddle is on all day, as is the ventilation and other equipment used to maintain cooling in the kitchen. I have never heard of a gas panini, either. Cooking equipment is generally production-related, however, and Panini's are generally not volume. Hope this helps.
Besides the energy requirement for ES requirements are also made on the consumption of water (Standard Sized Models: equal or less 4.25 gpc).
For a European project I want to show equivalency for a European (not Energy Star qualified) dishwasher. For the intent of this credit do I have to show equivalency for both, energy and water consumption? Or only for energy consumption.
This is an energy credit, not a water credit.
For this credit just energy.
If it is a Commercial Interiors project, EAc1.4 has the Energy Star component. Energy Star for Commercial Warewashers includes water usage. Since the more water that is used, the more primary water heat (hot water TO the dishwasher) water consumption does affect energy.
All our projects are in Sweden and we are constantly struggling with the Energy Star products, especially dishwashers, refrigerators, and commercial equipment. In July the USGBC has come out with an Global ACP guidance that explains even more information (water factor, energy factor, volume of water per cycle,etc.) that would be required of a product to prove equivalency with Energy Star. The catch of course it retrieving this information from the manufacture and establishing it that it is even better or equivalent to Energy Star. The latter part is still unclear from the USGBC.
Although this is a CI forum, the Europe ACP LEED EBOMEBOM is an acronym for Existing Buildings: Operations & Maintenance, one of the LEED 2009 rating sytems. guide credit MRc2 actually addresses other certification labels that are approved for electric powered equipment; Blue Angel, EU Energy Star, TCO. Why this was not included in CI, no clue.
Maybe you could write a CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide. Hope this helps.
(I will send a link to the Global ACP, when the USGBC website is back up and running next week)
Have you had any replies on this?
I have pushed the question further on another forum in EBOMEBOM is an acronym for Existing Buildings: Operations & Maintenance, one of the LEED 2009 rating sytems., MRc2. Message titled "Dishwasher - Water Consumption"
We have still not submitted anything to the USGBC to date. But are aiming to within one of our projects within 6 months.
Here is the link to the Global ACPs:
I can update hopefully in the near future.
We have a number of ice machines on our project that are Energy Star certified. The manufacturer will only provide us power usage in the form of kWhA kilowatt-hour is a unit of work or energy, measured as 1 kilowatt (1,000 watts) of power expended for 1 hour. One kWh is equivalent to 3,412 Btu./100 lbs of ice (which is the Energy Star criteria). From the spec sheet, we know that the maximum output is 390 lbs. over a 24 hour period. Is it acceptable to use this information, and calculate the watts by using the formula:
P(w) = 1000 x E(kWh) / t(hr)
For example, the machine uses 5.79kWh/100 lbs of ice. Multiply that by 390 lbs per 24 hours equals 22.581kWh per day. Using the formula above, this would translate to 952.125 watts.
Can we use this as our rated powerRated power is the nameplate power on a piece of equipment. It represents the capacity of the unit and is the maximum that it will draw. given that the manufacturer will only provide power use in kWh/100 lbs ice?
We also often have difficulty getting the rated powerRated power is the nameplate power on a piece of equipment. It represents the capacity of the unit and is the maximum that it will draw. of pieces of equipment. It's hard to get from manufacturers and finding a nameplate is unrealistic. We make our calculations with Volts x Amps to get kWhA kilowatt-hour is a unit of work or energy, measured as 1 kilowatt (1,000 watts) of power expended for 1 hour. One kWh is equivalent to 3,412 Btu. rated power. The ice machines I have seen cut sheets for do supply that info. We have been doing this consistently on our projects with no challenges.
kWhA kilowatt-hour is a unit of work or energy, measured as 1 kilowatt (1,000 watts) of power expended for 1 hour. One kWh is equivalent to 3,412 Btu. per 100 lbs. of ice is one of the most effective way to determine how much ice will be used. Same goes for warewashing in determining dishwasher run time. A kitchen designer will design for a meal count, and it is very easy to determine how much ice is needed to feed X number of people. A fast food figure is considered .9 lbs./guest; a hotel, 3-5 lbs./room, 10 lbs./patient bed., 1.7 lbs. sit down restaurant guest, etc. A salad bar using ice uses 30 lbs./sq. foot. So the really easy part is to factor the guests, and where else ice is used. A cold plate on a beverage dispenser is capacity of dispenser plus 40%. I love ice because it is very simple to figure out how much you need. Something else to consider is that numbers are based on 90 degree air, 70 degree water temperature, so climate has a big impact. If you want a chart of usage per guest depending on function, contact me and I will give it to you.
Hi, I have a question regarding the Energy Star Rated Ovens. I´m working with a LEED CI 2009 project in Argentina and I´m having trouble finding an ES Rated Oven. For LEED CI I have to document that at least 50% of my energy use for appliances and equipment comes from ES certified products. The project is mainly a kitchen and a dining room. I have a doubt with the ES Steam Ovens and want to verify that "Qualifying Products: Any commercial steam cooker that meets the definition in Section 1A is eligible
for the ENERGY STAR. For purposes of this Version 1.0 specification, only 3-, 4-, 5-, and 6-pan capacity units may qualify for ENERGY STAR."
This is taken from the document "Energy Star - Steam_Cooker_V1 0_FINAL_spec.pdf" from the Energy Star webpage.....
I want to verify that a 10 or a 20-pan oven is indeed excluded from the ES Rating so far.
As far as I can tell all steam cookers over 2 pans must comply. The document you cite appears to be from 2005 and could be out-of-date. The product criteria on the commercial steam cooker page indicates it applies to 3, 4, 5 and 6 pan or larger steam cookers.
I´m working in a project in Argentina which is up for LEED CI. The project is mainly a new commercial kitchen and dining area for 250 persons. The rest of the space has some offices for 50 persons, bathrooms, storage, etc. The main purpose for this addition is to serve other company areas that have been already certified under LEED CI.
The problem is that most of the kitchen equipment has an Energy Star equivalent but we have not been able to acquire / buy said equipment. There are very strict importing restrictions in the country and ES commercial kitchen equipment is not sold here. Any comments? Right now I do not even get to the 50% EAp2 prerequisite requirement.
I´m thinking of indicating that "Special circumstances preclude documentation of credit compliance with the submittal requirements outlined in this form"... I would send a thorough narrative and a letter from the owner stating they are committed to buy the rest of the equipment as ES... But do not know if this will suffice.... Any thoughts? Inputs?
I think you would need to demonstrate Energy Star equivalency related to the equipment you did buy to earn the credit. You are asking to be exempt which I do not think would be accepted. In my opinion there is not a real difference between not being willing to buy the ES equipment and not being able to do so. Your best bet would be to try and demonstrate that you have purchased energy efficient kitchen equipment in alignment with the credit intent.
Thanks Marcus. I´m still trying to figure out how the new Kitchen Equipment compares to the ES Standard.... Will see and let you know!
I cannot get the nameplate power from an Energy Star residential refrigerator used for a commercial project. I called the manufacturer, checked the manuals, etc. no luck. Can I calculate the rated powerRated power is the nameplate power on a piece of equipment. It represents the capacity of the unit and is the maximum that it will draw. in wattage from the published voltages times the amps? Really, it makes little difference - we have 100% energy star appliances whatever the number here is.
Bigger question - shouldn't this credit be determined by predicted kWhA kilowatt-hour is a unit of work or energy, measured as 1 kilowatt (1,000 watts) of power expended for 1 hour. One kWh is equivalent to 3,412 Btu. / year and not rated power? Annual expected usage is what Energy Star uses to rate products and what makes sense given the intent of the credit.
Same big question for lighting - actual predicted usage (with controls, etc) is what should count - not LPDLighting power density (LPD) is the amount of electric lighting, usually measured in watts per square foot, being used to illuminate a given space..
The idea is to isolate the scheduled run time from the overall power. Power is a design issue, energy use is an operational issue. Since schedules vary considerably it is more difficult to do comparisons.
sorry, not sure I agree with you Marcus. Designing a low energy building is all about understanding operational issues and offering effective options for occupants to be able to lower their energy use.
but on to more LEED nitty gritty - can you or anyone out there tell me whether LEED CI EAp2 and EAc1.4 still exempts existing equipment from being Energy Star rated? A review just back holds the prereq and credit pending with only the following comment:
'Please revise the Energy Star rated calculations to include all installed eligible equipment and appliances'
I was not stating my opinion on one vs the other, I was stating why I thought it is the way it is from a comparative perspective. This is a design based credit in a design based rating system. At this point there are no occupants to offer operational solutions. Design professionals understand W/sf but not kWhA kilowatt-hour is a unit of work or energy, measured as 1 kilowatt (1,000 watts) of power expended for 1 hour. One kWh is equivalent to 3,412 Btu./sf. So that is why it is the way it is in my opinion.
You make a good point about understanding operational issues related to energy use. Not sure how much influence these calculations have since they are just a prediction and the real bottom line is in the actual operation. Just like an energy model the true value of making a prediction is when you compare it to the actual data and learn from it. Just making the prediction has very limited value in my expereince.
It is my understanding that only newly purchased equipment counts. This was a change awhile back. I have argued in the past that all the existing equipment should count. Operationally the organization should have already been purchasing Energy Star equipment. To let a project buy one new copier and exempt the rest of what they are going to use makes no sense to me.
Agreed, the equipment actually USED is what is vital. In the case of commercial kitchens, it's a shame that old equipment can be re-used and the job isn't penalized, particularly when it comes to dishwashers, where the water usage has dropped dramatically. Example, over 300 gallons/hour down to 112-126. E/S standard is based on gallons per rack, one rack, 2.5 people approx. and idle energy, which is like "breaktime" for a dishwasher, because it isn't running. Dishwashers are frequently leased from chemical companies, however, and end up NIC, but their water and power are generally listed in the job.
I have a large CI project where the client will be moving to a new facility, bringing with them a lot of office equipment they currently are using. Would these credits still be achievable? Thanks!

EAp2 requires that 50% of the total eligible power rating be from Energy Star appliances. EAc1.4 grants points for going beyond 70%.
If a project is pursuing the energy modeling compliance path, then you can benefit from the reduced plug loads associated with Energy Star labeled products.
