Hi All,
We're reviewing energy cost and consumption data in our new, LEED-Silver certified residence hall and finding quite low numbers. Do you have similar energy consumption in your building?
The building is a 54,519 square foot residence hall that opened in January 2009. It uses ground source heat pumps for cooling and heating the building (the heat pumps also heat the hot water). We're located in New Jersey.
Building Consumption (BTU/yr): 735,324,256
BTU/sqft/day: 37
BTU/sqft/yr: 13,487
Energy Intensity (MMBTU/sqft/yr): 36,952
Much appreciated!

If you mean that the building used 1,100 BTU's per square foot for the year that number is way too low...just doesn't make sense unless I don't understand the context. and .95KWH/sq ft....same thing. What are the totals you're working with?
The comparison is hard because the numbers are missing time units.
A rough calculation for energy consumption using the numbers given above would be something like:
Total # of BTU's consumed per sq. ft. per year = (Total BTUs consumed in the year) / { (total square footage) * (# of operational days) }
X = 836,483,600.00 BTUs/ (54000 sq. ft.) * (number of days the building was active per year)
Once the time units are included in the calculation, it might be easier for you to compare with other buildings elsewhere.
Hope this is helpful.
