Criteria

Institution supports the development and use of clean and renewable energy sources, using any one or combination of the following options. 

                                    Option 1:                                                 

Generating electricity from clean and renewable energy sources on campus and retaining or retiring the rights to the environmental attributes of such electricity. (In other words, if the institution has sold Renewable Energy Credits for the clean and renewable energy it generated, it may not claim such energy here.) The on-site renewable energy generating devices may be owned and/or maintained by another party as long as the institution has contractual rights to the associated environmental attributes. 

Option 2:

Using renewable sources for non-electric, on-site energy generation, such as biomass for heating. 

Option 3:

Catalyzing the development of off-site clean and renewable energy sources (e.g. an off-campus wind farm that was designed and built to supply electricity to the institution) and retaining the environmental attributes of that energy.

Option 4:

Purchasing the environmental attributes of electricity in the form of Renewable Energy Certificates (RECs) or other similar renewable energy products that are either Green-e Energy certified or meet Green-e Energy’s technical requirements and are verified as such by a third party, or purchasing renewable electricity through the institution’s electric utility through a certified green power purchasing option. 

Since this credit is intended to recognize institutions that are actively supporting the development and use of clean and renewable energy, neither the electric grid mix for the region in which the institution is located nor the grid mix reported by the electric utility that serves the institution count for this credit. 

The following renewable systems are eligible for this credit: 

  • Concentrated solar thermal 
  • Geothermal systems that generate electricity 
  • Low-impact hydroelectric power 
  • Solar photovoltaic 
  • Wave and tidal power 
  • Wind 

Biofuels from the following sources are eligible: 

  • Agricultural crops 
  • Agricultural waste 
  • Animal waste 
  • Landfill gas 
  • Untreated wood waste 
  • Other organic waste 

Technologies that reduce the amount of energy used but do not generate renewable energy do not count for this credit. For example, daylighting, passive solar design, and ground-source heat pumps are not counted in this credit. The benefits of such strategies, as well as improved efficiencies achieved through using cogeneration technologies, are captured by OP 1: Greenhouse Gas Emissions and OP 8: Building Energy Consumption

Transportation fuels, which are covered by OP 1: Greenhouse Gas Emissions and OP 18: Campus Fleet, are not included in this credit. 


Applicability

This credit applies to all institutions. 


Scoring

Institutions earn the maximum of 4 points for this credit by obtaining energy from clean and/or renewable sources (Options 1-3) and/or by purchasing RECs or green power from the electric utility (Option 4) equivalent to 100 percent of total campus energy consumption. Incremental points are awarded based on the amount of clean and renewable energy generated or purchased compared to total campus energy consumption. For example, an institution that obtained an amount of energy from clean and renewable sources equivalent to half of its total energy consumption would earn 2 points (half of the points available for this credit). 

See scoring table and example in the STARS Technical Manual.


Measurement

Timeframe

Report the most recent data available. Institutions may choose the annual start and end dates that work best with the data they have (e.g. fiscal or calendar year), as long as data are reported from a consecutive 12-month period. 

Sampling and Data Standards

Report all on-site, stationary energy that was consumed by the institution (as the institution defines in the overall STARS institutional boundary). Reporting on a sample or subset of energy generation and consumption is not allowed for this credit. 

To aggregate energy consumption data from multiple sources, figures should be converted into MMBtu (one million British thermal units—a standard measure of energy) using the following equivalents: 

Energy Unit  MMBtu Equivalent 
1 kWh  0.003412 
1 MWh  3.412 
1 therm  0.1 
1 kBtu  0.001 
1 ton-hour  0.012 
1 MJ  0.000948
