FAQs about EAc1 :

Our building includes a large laboratory space. Can our project benchmark under the Labs21 program?

We have an international project and the space type is eligible for an Energy Star rating. Can we pursue Case 1 to demonstrate compliance given the recently released alternative compliance paths for international projects?

We have a number of buildings on a single campus that we would like to certify at the same time. Is it possible to benchmark the buildings at the campus level?

I have a mixed-use building and am wondering if it is possible to pursue the prerequisite through Case 1. How do we proceed?

We have a building that consists of two attached structures and it’s unclear if we have to consider it a single building or if it should be certified as two separate buildings and benchmarked accordingly. How should we proceed?

How long is an Energy Star label valid to use with a streamlined approach for Case 1?

Our building includes heavy process loads that significantly increase the overall energy use in the building. If we submeter these loads, can we exclude this energy use for benchmarking purposes?

We have installed submeters on our building but the utility bill includes energy use from several other buildings located on the same campus. How do we reconcile this during the LEED review process?

When is it possible to exclude up to 10% of the building from EAp2?

What do I do if the number of building occupants, operating hours, or vacant space changes during the performance period?

If you pursue the streamlined path for an Energy Star label, should the performance period for EAc6 match the 12-month time frame of the label?

How do I account for computers with multiple monitors on Portfolio Manager?

How should I treat vacant space on Portfolio Manager?

EBOM-2009 EAc1:Optimize Energy Performance

Protfolio Manager Analysis

We are working on projects for LEED EBO&M and have some doubts related to the credits EApre1& EAc1. The Portfolio Manager Analysis is unable to classify the energy consumption of the plant within the standards of buildings. Thus, the use of a spreadsheet according to LEED is also unable to classify the energy consumption. Therefore we have some questions to ask you: 1 - Is it possible not to consider energy spent for the industrial process and utilities, considering only energy spent for building´s systems (HVAC, elevators etc)? 2 - If option one (1) is not possible, can we consider the energy consumption per unit of production (for example, kWh / kg produced rather than kWh/m2)? 3 - We would also like to know if is it acceptable to use Energy Star Index for industrial plants?

Hi Paola, not sure how much my reply will help you but seems like your issue right now is "pre-LEED". I would start with Energy Star as it has pretty strong support when it comes to industrial facilities. I would reach out to buildings@energystar.gov directly on best practices and strategies how to correctly benchmark. Once you have cleared that up, visit this LEED user area again and check out the offline calculator in the documentation toolkit section. You may end up having to use this if the facility cannot earn an Energy Star score.
