Further progress on building data

Hi everyone,

Just wanted to let you know that I added another column to our "Building Energy Use" spreadsheet.

The additional column is "MMBTU's / square foot" for electricity only.

Given what we all discussed, additional columns can be added for water, natural gas and steam once the meters are installed.

I figured it would be good to calculate the energy use (for electricity) per square foot using the GROSS sq. footage numbers, considering that would account for all the additional energy that's inadvertently used because of the gaps in the walls etc., although I'm also open to using the NET sq. footage numbers too.

(For those of you not familiar with the difference between GROSS and NET square feet, GROSS indicates the total square footage of the building footprint, whereas NET stands for all the usable space (excluding interior walls, gaps, voids etc.).

What do you think?
