we are a Sri Lankan company and we are planning on going for LEEDS EB OM certification. As we are a foreign entity we are facing problems on how to establish the Energy use base line.Further if we are to follow according to the Case 2, Option 2 of the reference guide we have a problem as we don’t have complete Energy data of the factory for past consecutive 3 years. The reason is that we purchased the factory couple of years back and the previous owners do not have any record of the energy use. Of course we can provide the Electricity use data of past 3 years but our problem lies in the energy data related to the Steam energy (Boiler) and Generator usage. We only have comprehensive data of about a year (Energy data representing all energy loads).
Please give us your opinion on how to proceed....

As I understand it, the EBOM certification is usually a 1-2 year process. Get the building ready (e.g. install the needed meters, etc.) and then start the "performance period" meaning start measuring and recording into Energy Star Portfolio Manager.
Your building is broken down into space types in the Portfolio Manager. These space types have their own "baseline". The Portfolio Manager then calculates the "baseline" for your whole building from these space types and geographic (i.e. weather normilized) data.
This is how I understand it, but I have no EBOM experience first hand yet, so double check me.
Regards,
Jean.

Thanks for the information.
In the mean time do you know in calculating the fuel usage, whether the manual recorded fuel usage data is sufficient? Because at the moment our fuel usage is recorded manually by tracking the fuel inventory records. Do we have to use meters to the equipments in measuring as we can determine the monthly usage in the current method that we are following..

Rashid,
This is a bit of a tricky situation, since factory facilities generally really rely on showing improvement over the three-year historic baseline. Is it the type of factory for which you might be able to compare yourself to other facilities (e.g., are there other factories in the area that produce similar goods)?
Given your situation, manual recordings of fuel usage seems like it should be acceptable, but you may want to send in a CIR at some point to get explicit clearance for this. Also, submetering specific equipment wouldn't be necessary, as long as you have a way to account for all of the energy used in the facility.
