We attach to this credit the excel "OP 5-Energy Efficiency of Buildings" to explain and show how we consider our 4 campuses in the calculations.
PART 1:
1. Calculate the parameter* separately for each of the campuses
2. Obtain a single value of the parameter*, through an area weighted average for the 4 campuses (cell I22). This value is 91.66 Btu / GSM / Degree-day (°C).
3. We "search" for the value of the parameter "Total degree-day" that allows us to obtain the value calculated in point 2. The "Goal Seek" tool in excel is used to "find" the value of "Total degree-days" which gives us as a result the "Total energy consumption (site energy) per unit of EUI adjusted floor area per degree-day" calculated in cell I22. The total degree-days value found is: 4.028 (°C).
4. We divide the value calculated in point 3 ("total degree-days") by "cooling degree-days" plus "heating degree-days".
Parameter*: Total energy consumption (site energy) per unit of EUI-adjusted floor area per degree-day.
PART 2:
Since 95% of the electricity purchased at IESE comes from Europe, we consider a source ratio of 2.
Imported electricity by campus, performance year (kWh):
Barcelona: 3,953,789.34
Madrid: 2,072,878.00
Munich: 72,821.67
New York: 350,400
TOTAL: (3,953,789.34 + 2,072,878.00 + 72,821.67 + 350,400) = 6,449,889.01
Energy consumption in European countries: (6,449,889.01- 350,400)/ 6,449,889.01 = 95%.
For this reason, we consider a source ratio of 2.
