Most campuses use the Campus Carbon Calculator
Scope 1, 2 and 3 emissions, including components of each such as air travel and commuting are to be reportedMethods
Size and setting classification (residential nature)
Land-grant institutionData from other sources
Small data set with all of above information (n=52)
Principal factor analysis to tease out most significant factors
Population showed a lot of colinearity, as did square footage although to a lesser extent
HDD and CDD explained less of the variance than the other independent variablesData analysis
S12 = Scope 1 and 2 emissions
GSF = Gross square feet
CDD = total cooling degree days/yr
HDD = total heating degree days/yr
log (S123) = -1.25 + 0.92 log (GSF)
p<0.0001; R2=0.795Scope 1 and 2 vs. Gross Emissions
CE = calculated greenhouse gas emissions from commuting to campus (metric tons CO2-e)
M = medical school (0=no; 1=yes)
FTE = full-time equivalent enrollment as calculated by the institutionGross emissions model n=135
The parameter estimate for LSF is more than 10X than for ONSF in both models and the parameter estimate for RSF is at least 2X ONSF. This shows a greater influence on emissions from these types of uses.
Smaller schools less influenced by student population and building space than larger schools.Conclusions
Conduct an in-depth examination of the institutional factors that influence emissions.Conclusions
Do we need multiple and/or large offices for faculty and staff, especially when we can telecommute?
Is space fully utilized for intended function?
Is it necessary that the institution support activities such as facility- (and energy-) intensive research?
Has vacated space been fully decommissioned and how can it be renovated and reassigned?Beyond technical solutions
