Minimum Energy Performance

Hello, To your first question, it sounds like you would enter the gas consumption on Portfolio Manager that was used to generate electricity on-site . As you mentioned, since the facility is off the grid, there wouldn't need to be an electric meter, if all of the energy consumed by the building was covered by the gas consumption/meter. To your second question, it is expected that facilities such as yours normalize annual energy use based on changes to the operations over time. For example, if your facility produces a product, you might normalize the annual energy use from the historic years based on increasing or decreasing production compared to the performance period year. When going that route, be sure to be able to show that there is a statistically significant relationship between the variable that you choose to normalize with and the facility energy consumption.

I concur with Ben. To add to Ben's expert response: LEED Interpretation #10220 provides guidance: http://www.usgbc.org/node/1731052?view=interpretations&return=/credits/existing-buildings/v2009 GBCI may require the normalization to include raw product. (e.g. btu per pound a raw material) Hope this helps.
