EBOM-2009 EAc1: Optimize Energy Performance
I am working on a facility that cannot obtain an Energy Star score due to building type. I wish to use the Case 2 Option 2C using a set of comparable buildings. However, since the facility is new, I do not have 3 years of historical data to use. It seems that if I cannot fill out option 2B details (historical data), I am not allowed to obtain a score using comparable buildings.
is there a way out? The building has very good energy efficiency and I am stuck with just passing the pre-req.

Our building includes a large laboratory space. Can our project benchmark under the Labs21 program?
How long is an Energy Star label valid to use with a streamlined approach for Case 1?
When is it possible to exclude up to 10% of the building from EAp2?
How do I account for computers with multiple monitors on Portfolio Manager?

Hi Magda,
Do you have at least one year of data and do you have energy data for a set of comparable buildings? If so, I wonder if GBCI might allow you to enter a single annual energy value for each of the historic years. That way, the historic comparison would be neutral and you would demonstrate compliance via improved performance over the comparable building set. I don't know if GBCI would accept this approach but it seems like a possibility. I wouldn't attempt it without getting in touch with GBCI first.

(1) Kindly can you give me a example with rough calculation regarding normalization ( energy consumption per unit of product )
How The 'total annual energy consumption / total annual units produced' must be compared against the baseline because the baseline power consumption is lower then performance year due to increase in number of machines ?
(2) Yes baseline will be of three years but as per leed reference guide we will calculate average of these three years then compare it with performance year.
(3) there is also confusion on leedonline form which make addition of all three baseline years value and compare the result to the performance year instead of calculating average and then comparing average to performance year.
why addition of all three years because through this results shows large saving ?
