All ISO37120 Indicators are a subclass of the GCI_Quantity. They then inherit all of the properties including placenames, populations, provenance, trust, etc.

Energy Indicators
http://ontology.eil.utoronto.ca/ISO37120.owl#7.1
Total residential electrical energy use per capita shall be calculated as the total residential electrical usage of a city in kilowatt hours (numerator) divided by the total population of the city (denominator). The result shall be expressed as the total residential electrical use per capita in kilowatt hours/year.
http://ontology.eil.utoronto.ca/ISO37120.owl#7.1
Total residential electrical energy use per capita (kWh/year) (core indicator)
http://ontology.eil.utoronto.ca/ISO37120.owl#7.2
The percentage of city population with authorized electrical service shall be calculated as the number of persons in the city with lawful connection to the electrical supply system (numerator) divided by the total population of the city (denominator). The result shall then be multiplied by 100 and expressed as a percentage.
The number of city households lawfully connected to the electricity grid shall be multiplied by the current average city household size to determine the number of city residents with lawful connection to the electricity supply system (the electricity grid).
NOTE Most electricity supply authorities distinguish billing accounts to residential and non residential establishments. Residential establishments in most cities equate to households (although in some condominiums, the body corporate holds the account for multiple households).

Percentage of city population with authorized electrical service (core indicator)
http://ontology.eil.utoronto.ca/ISO37120.owl#7.3
Energy consumption of public buildings shall be calculated per year as the total use of electricity at final consumption stage by public buildings (kWh) within a city (numerator) divided by total floor space of these buildings in square meters (m2) (denominator). The result shall be expressed as the total energy consumption of public buildings per year in kilowatt hours per square meter.
NOTE Public buildings are government owned buildings such as government offices, hospitals and schools.
http://ontology.eil.utoronto.ca/ISO37120.owl#7.3
Energy consumption of public buildings per year (kWh/m2) (core indicator)
http://ontology.eil.utoronto.ca/ISO37120.owl#7.4
The share of a city’s total energy consumption derived from renewable sources shall be calculated as the total consumption of electricity generated from renewable sources (numerator) divided by total energy consumption (denominator). The result shall then be multiplied by 100 and expressed as a percentage. Consumption of renewable sources should include geothermal, solar, wind, hydro, tide and wave energy, and combustibles, such as biomass.
http://ontology.eil.utoronto.ca/ISO37120.owl#7.4
The percentage of total energy derived from renewable sources, as a share of the city’s total energy consumption (core indicator)
http://ontology.eil.utoronto.ca/ISO37120.owl#7.5
Total electrical energy use per capita shall be calculated as the total electrical usage of a city in kilowatt hours including residential and non-residential use (numerator) divided by the total population of the city (denominator). The result shall be expressed as the total electrical use per capita in kilowatt hours/year.
http://ontology.eil.utoronto.ca/ISO37120.owl#7.5
Total electrical energy use per capita (kWh/year) (supporting indicator)
http://ontology.eil.utoronto.ca/ISO37120.owl#7.6
The average number of electrical interruptions per customer per year shall be calculated as the total number of customer interruptions (numerator) divided by the total number of customers served (denominator). The result shall be expressed as the average number of electrical interruptions per customer per year.
Electrical interruptions shall include both residential and non-residential.
It is normal to expect interruptions in service for a number of reasons including scheduled maintenance and equipment breakdown. To establish the opportunity to have a reasonable comparison between energy providers, major storms and weather events should be excluded due to their unpredictability and randomness since they are difficult to predict, prevent or mitigate against.
NOTE This indicator is affected by the age, standard of maintenance and reliability of the infrastructure that constitutes the electricity grid and the electricity transmission capacity that services the grid. The ability of both the grid and its electricity transmission capacity to provide supply on demand and to cope with peak loads is also an important consideration.

Average number of electrical interruptions per customer per year (supporting indicator)
http://ontology.eil.utoronto.ca/ISO37120.owl#7.7
The average length of electrical interruptions shall be calculated as the sum of the duration of all customer interruptions in hours (numerator) divided by the total number of customer interruptions (denominator). The result shall be expressed as the average length of electrical interruptions in hours.
Electrical interruptions shall include both residential and non-residential.
