Category Value

Category values represent properties of a Function, related to categories. Category values are different from Function values in that they are always set in relation to a specific Category.

A Function, and by extension a Building always belongs to one or more categories. The value of a Category Value for a Function or Building is calculated by a weighted average, where the Category weight (Category Value) is used for the weights. The attribute name of a particular Category value is obtained by prepending the Category name to the Category value. For example, the demand for parking lots for offices is obtained using the attribute OFFICE_PARKING_LOTS_DEMAND_PER_M2.

Construction

Name	Attribute	Unit	Range	Description
Category weight	CATEGORY_WEIGHT	decimal	4.9E-324 to 1.7976931348623157E308	How much of a building of this function is classified under the specified category.
Unit size	UNIT_SIZE_M2	m²/unit	0 to 1.7976931348623157E308	How large a single housing unit within this Building is. This is only relevant for residential categories.

Financial

Name	Attribute	Unit	Range	Description
Buyout cost	BUYOUT_COST_M2	currency/m²	0 to 1.7976931348623157E308	How much it costs, in addition to the demolition costs, to demolish this Building during a session, when the Building is not vacant. These costs are due to eviction or buyout of existing tenants.
Construction cost	CONSTRUCTION_COST_M2	currency/m²	0 to 1.7976931348623157E308	How much it costs to create a new building, when using this function as an action during a session.
Demolition cost	DEMOLISH_COST_M2	currency/m²	0 to 1.7976931348623157E308	How much it costs to demolish this Building during a session. If the building is not vacant, the buyout costs are applicable as well, in addition to the demolition costs.
Sell price	SELL_PRICE_M2	currency/m²	0 to 1.7976931348623157E308	How much revenue is generated for the owner, when a building of this function is created during a session. The income is only generated once, when the construction of the building has completed.

Network

Name	Attribute	Unit	Range	Description
Heat flow change per year	HEAT_FLOW_M2_CHANGE_PER_YEAR	m²/year	-1.7976931348623157E308 to 1.7976931348623157E308	For any net load connected to an address part of a Building of this function, the amount of resources (FLOW) requested in addition to those in the starting year during every subsequent year. The amount of resources requested starts at HEAT_FLOW_M2_START_VALUE in the start year, and is then increased by this value every year until the building's year of creation, and finally multiplied by the size of the address(es) the net load is associated with to get a default FLOW value for the net load.
Heat flow formula start year	HEAT_FLOW_M2_START_YEAR	year	0 to 3000	For any net load connected to an Address part of a Building of this function, the start year for the calculation of the amount of resources (FLOW) requested. The amount of resources requests starts at HEAT_FLOW_M2_START_VALUE in this year, and is then increased by HEAT_FLOW_M2_CHANGE_PER_YEAR every year until the building's year of creation, and finally multiplied by the size of the address(es) the net load is associated with to get a default FLOW value for the net load.
Heat flow to power multiplier	HEAT_POWER_TO_FLOW_MULTIPLIER	factor	-1.7976931348623157E308 to 1.7976931348623157E308	For any net load connected to an address part of a building of this function, the divisor used to convert the automatically calculated FLOW to an automatically calculated POWER attribute. The automatically calculated FLOW divided by this value is the automatically calculated POWER. Note that an explicitly defined FLOW attribute is not used in this calculation.
Heat flow value at start year	HEAT_FLOW_M2_START_VALUE	m²	-100 to 100	For any net load connected to an address part of a Building of this function, the amount of resources (FLOW) requested by the net load in the defined starting year. This value is increased with the HEAT_FLOW_M2_CHANGE_PER_YEAR, until the building's year of Building, and finally multiplied by the size of the address(es) the net load is associated with to get a default FLOW value for the net load.

Parking

Name	Attribute	Unit	Range	Description
Parking lots	PARKING_LOTS_PER_M2	parking lot/m²	0 to 1	How many parking lots are available per m² of this building.
Parking lots demand	PARKING_LOTS_DEMAND_PER_M2	parking lot/m²	0 to 2	How many parking lots are required per m² of this building.
