5.1 Energy consumption per square meter

Convert site energy figures to megawatt-hours (MWh) using the STARS energy calculator or an equivalent resource.

Performance year for energy use:
2023

Peer group:
Baccalaureate colleges and boarding schools

Gross floor area of building space:
183,997 Square meters

Electricity
Electricity generated by on-site renewable systems:
99.60 Megawatt-hours

Description of the on-site renewable systems:

We have a 100 kw solar array (294 panels altogether) on the top of the science center which generates roughly 3% of the Science Center's use. In 2023 it generated 99.6 mWh of renewable generated electricity.

 

 


On-site renewable electricity exported:
0 Megawatt-hours

Electricity from off-site sources:
11,644 Megawatt-hours

Stationary fuels

Include all liquid, solid, and gaseous fuel products sourced during the performance year for the purpose of producing electricity and/or thermal energy, irrespective of whether they were used or not. Transportation fuels are excluded.

Natural gas:
64,175 Megawatt-hours

Propane/LPG:
145 Megawatt-hours

Heating oil:
272 Megawatt-hours

Coal/coke:
0 Megawatt-hours

Bioenergy products:
0 Megawatt-hours

Other stationary fuels:

Heating and cooling from off-site sources

Include all district heating and cooling products sourced during the performance year from a utility or municipal facility.

Steam from off-site sources:
0 Megawatt-hours

Hot water from off-site sources:
0 Megawatt-hours

Chilled water from off-site sources:
0 Megawatt-hours

The Reporting Tool will automatically calculate the following six figures:

Total electricity consumption:
11,743.60 Megawatt-hours

Total stationary fuel consumption:
64,592 Megawatt-hours

Total heating and cooling from off-site sources:
0 Megawatt-hours

Total annual energy consumption:
76,335.60 Megawatt-hours

Annual energy consumption per unit of floor area:
414.87 Kilowatt-hours per square meter

Points earned for indicator OP 5.1:
0.93

5.2 Energy consumption per person

Full-time equivalent student enrollment:
2,141

Full-time equivalent of employees:
1,065

The Reporting Tool will automatically calculate the following three figures:

Full-time equivalent students and employees:
3,206

Annual energy consumption per person:
23,810.23 Kilowatt-hours

Points earned for indicator OP 5.2:
0.76

5.3 Percentage of energy from renewable sources

Each MWh may only be counted once, i.e., in no more than one of the documentation fields provided. Note that electricity generated by on-site renewable systems is reported above for indicator 5.1. Energy attribute certificates (EACs) include RECs, GOs, and I-RECs.

Contractual instruments for renewable electricity
Energy attribute certificates (EACs) sold or not owned by the institution:
0 Megawatt-hours

Electricity from certified off-site renewable sources:
0 Megawatt-hours

Description of the certified off-site renewable sources of electricity:
---

Electricity from uncertified off-site renewable sources:
2,911 Megawatt-hours

Description of the uncertified off-site renewable sources of electricity:

The compliance RECs from Constellation represent all of the renewable energy that Constellation retires on our behalf, and therefore can be claimed by Amherst. The percentage for Class I and CES compliance RECs was 24% in calendar year 2022 and 26% in calendar year 2023. 

25% of 11,644 mwh (total purchased electricity) = 2,911 mwh

We used data provided by Constellation Energy to calculate the proportion of electricity sourced from renewable sources. From 7/1/2022 to 6/30/2023, 41.1% of energy supplied to customers came from renewable sources, but we are only claiming the Class I and CES complaince RECS in our reporting.

source percent renewable
coal 0.2  
natural gas 43.2  
oil 5.3  
system mix 10.1  
hydro large 13.7 x
municipal trash 3 x
nuclear 6.9 x
other renewable 2.8 x
solar 9 x
wind 5.7 x

 

 

 


Certified unbundled EACs:
7,180 Megawatt-hours

Description of the certified unbundled EACs:

Amherst purchased 3,834 Green-e RECs from Sterling Planet the first half of FY23 and then purchased an additional 3,346 2023 Green-e RECs from 3 Degrees Group the second half of FY23. So 7,180 Green-e RECS total for FY23.


Renewable stationary fuels

Convert all units to MWh using the STARS energy calculator or an equivalent resource. Include products sourced during the performance year for the purpose of producing electricity and/or thermal energy, irrespective of whether they were used or not.
