FAQs about EAp2 :

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

How should I treat vacant space on Portfolio Manager?

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?

EBOM-2009 EAp2:Minimum Energy Efficiency Performance

Further normalized EUI

Hi there, in our efforts to achieve LEED EBOM certification for a production facility (garment washing plant) in Dhaka, we have implemented energy conservation measures. However, the source EUI has increased beyond historical average, since our production also got increased by 60%, due to market demand. Now we have further normalized the weather-normalized EUI based on production level, as suggested by normalization procedures in “Guidance for Normalizing Environmental Performance Results”, published by Environmental protect agency (Refer page no 9 of 25).. We have used following formula: 1) Production Normalizing factor = production in current year ÷ production in baseline year 2) Production normalized EUI = Weather normalized EUI ÷ Production Normalizing factor. Though we have followed the guidelines, still not sure whether we are on right course for GBCI acceptance.. Or is there any other complicated calculations involved? Is there any other guidebooks accepted by GBCI? Thanks in anticipation..

Your methodology looks sound and we are currently using a similar normalization approach with a manufacturing facility, though the project has not gone through the review process yet. See a relevant LEED Interpretation here that provides confirmation that normalizing for production, in addition to weather and size, can be an acceptable. https://www.usgbc.org/leedinterpretations/LIDetails.aspx?liaccessid=5184
