Schema

The schema is a .json file containing key-value pairs that define the parameters to use in constructing a citylearn.citylearn.CityLearnEnv object (environment). The aim of the schema is to provide an interface that is analogous to the .idf used to define an EnergyPlus model.

Schema Definition

The key-value pairs in the schema are summarized in the table:

Key	Definition
root_directory	Absolute path to directory that contains the data files including the schema. Can be null if schema is supplied to citylearn.citylearn.CityLearnEnv constructor as a filepath.
central_agent	Set to true for centralized control architecture else false.
simulation_start_time_step	Time step in the data files to start the simulation from.
simulation_end_time_step	Time step in the data files to end the simulation at.
episodes	The number of episodes/epochs to simulate.
seconds_per_time_step	Used to define the time resolution of the data files.
observations	Used to define the observation space.
observations:<observation>:active	Set to true if named <observation> should be added to the observation space and provided to the agent else false.
observations:<observation>:shared_in_central_agent	Set to true if if named <observation> values will be common in all buildings.
actions	Used to define the action space.
actions:<action>:active	Set to true if agent will provide named <action> to environment.
agent	Used tp define control algorithm to use in simulation.
agent:type	Control algorithm class in citylearn.agents or user-defined algorithm class path.
agent:attributes	Used to define attributes/hyperparameters that are used to construct control algorithm class specified in agent:type.
agent:attributes:<attribute>	Value to set named <attribute> to in control algorithm.
reward_function	Used to define reward function to use in simulation.
reward_function:type	Reward function class in citylearn.reward_function or user-defined reward function class path.
reward_function:attributes	Used to define attributes/hyperparameters that are used to construct reward function class specified in reward_function:type.
reward_function:attributes:<attribute>	Value to set named <attribute> to in reward function.
buildings	Used tp define buildings to use in simulation.
buildings:<building_name>	Used to define the attributes of a building uniquely named <building_name>.
buildings:<building_name>:include	Set to true if <building_name> should be included in simulation.
buildings:<building_name>:energy_simulation	Filename of building data file for <building_name>. This file must be located in root_directory.
buildings:<building_name>:weather	Filename of weather data file for <building_name>. This file must be located in root_directory.
buildings:<building_name>:carbon_intensity	Filename of carbon intensity data file for <building_name>. This file must be located in root_directory.
buildings:<building_name>:pricing	Filename of electricity pricing data file for <building_name>. This file must be located in root_directory.
buildings:<building_name>:inactive_observations	List of building-specific inactive observations that overrides observations:<observation>:active.
buildings:<building_name>:inactive_actions	List of building-specific inactive actions that overrides actions:<action>:active.
buildings:<building_name>:<device>	Used to define a <device> for <building_name>. <device> can be cooling_device, heating_device, dhw_device, cooling_storage, heating_storage, dhw_storage, electrical_storage or pv.
buildings:<building_name>:<device>:type	<device> class in citylearn.energy_model or user-defined device class path.
buildings:<building_name>:<device>:autosize	Set to true if the <device> should be autosized for <building_name> else false.
buildings:<building_name>:<device>:autosize_attributes	Used to define attributes that are used to autosize <device> class specified in buildings:<building_name>:<device>:type.
buildings:<building_name>:<device>:autosize_attributes:<attribute>	Value to set named <attribute> to autosize <device> class specified in buildings:<building_name>:<device>:type.
buildings:<building_name>:<device>:attributes	Used to define attributes that are used to construct <device> class specified in buildings:<building_name>:<device>:type.
buildings:<building_name>:<device>:attributes:<attribute>	Value to set named <attribute> of <device> class specified in buildings:<building_name>:<device>:type.
