EnergyPlus EpJSON Input Schemaο
The EnergyPlus input syntax is changing from IDD/IDF to epJSON. A schema is currently autogenerated from the IDD but will eventually become the fundamental input schema. The schema objects are described here.

SimulationControlο
Note that the following 3 fields are related to the Sizing:Zone, Sizing:System, and Sizing:Plant objects. Having these fields set to Yes but no corresponding Sizing object will not cause the sizing to be done. However, having any of these fields set to No, the corresponding Sizing object is ignored. Note also, if you want to do system sizing, you must also do zone sizing in the same run or an error will result.

EcoRoof model, plant layer plus soil layer Implemented by Portland State University (Sailor et al., January, 2007) only one material must be referenced per simulation though the same EcoRoof material could be used in multiple constructions. New moisture redistribution scheme (2010) requires higher number of timesteps per hour (minimum 12 recommended).

ZoneHVAC:HybridUnitaryHVACο
Hybrid Unitary HVAC. A black box model for multi-mode packaged forced air equipment. Independent variables include outdoor air conditions and indoor air conditions. Controlled inputs include operating mode, supply air flow rate, and outdoor air faction. Empirical lookup tables are required to map supply air temperature supply air humidity, electricity use, fuel uses, water use, fan electricity use, and external static pressure as a function of each independent variable and each controlled input. In each timestep the model will choose one or more combinations of settings for mode, supply air flow rate, outdoor air faction, and part runtime fraction so as to satisfy zone requests for sensible cooling, heating, ventilation, and/or dehumidification with the least resource consumption. Equipment in this class may consume electricity, water, and up to two additional fuel types.

List equipment in simulation order. Note that an ZoneHVAC:AirDistributionUnit object must be listed in this statement if there is a forced air system serving the zone from the air loop. Equipment is simulated in the order specified by Zone Equipment Cooling Sequence and Zone Equipment Heating or No-Load Sequence, depending on the thermostat request. For equipment of similar type, assign sequence 1 to the first system intended to serve that type of load. For situations where one or more equipment types has limited capacity or limited control, order the sequence so that the most controllable piece of equipment runs last. For example, with a dedicated outdoor air system (DOAS), the air terminal for the DOAS should be assigned Heating Sequence = 1 and Cooling Sequence = 1. Any other equipment should be assigned sequence 2 or higher so that it will see the net load after the DOAS air is added to the zone.

Coil:Heating:Desuperheaterο
Desuperheater air heating coil. The heating energy provided by this coil is reclaimed from the superheated refrigerant gas leaving a compressor and does not impact the performance of the compressor. If the coil is located directly in an air loop branch or outdoor air equipment list, then it is controlled on leaving air temperature and the Temperature Setpoint Node Name must be specified. If the coil is contained within another component such as a unitary system, then the coil is controlled by the parent component and the setpoint node name is not entered.

This object models a solid desiccant dehumidifier. The process air stream is the air which is dehumidified. The regeneration air stream is the air which is heated to regenerate the desiccant. This object determines the process air outlet conditions, the load on the regeneration heating coil, the electric power consumption for the wheel rotor motor, and the regeneration air fan mass flow rate. All other heat exchangers are modeled as separate objects connected to the inlet and outlet nodes of the dehumidifier. The solid desiccant dehumidifier is typically used in an AirLoopHVAC:OutdoorAirSystem, but can also be specified in any AirLoopHVAC.

ChillerHeaterPerformance:Electric:EIRο
This chiller model is a generic chiller-heater where the cooling mode performance is a function of condenser entering or leaving fluid temperature and the heating mode performance is typically a function of condenser leaving fluid temperature. Performance at off-reference conditions is modeled using three polynomial equations per mode. Six curve objects are required.

CoolingTower:VariableSpeedο
This open wet tower model is based on purely empirical algorithms derived from manufacturerβs performance data or field measurements. The user can select from two existing algorithms (CoolTools or YorkCalc), or they can enter their own correlation for approach temperature by using a variable speed tower model coefficient object. For a multi-cell tower, the capacity and air/water flow rate inputs are for the entire tower.

WaterUse:Equipmentο
A generalized object for simulating all water end uses. Hot and cold water uses are included, as well as controlled mixing of hot and cold water at the tap. The WaterUse:Equipment object can be used stand-alone, or coupled into a plant loop using the WaterUse:Connections object (see below). The WaterUse:Connections object allows water uses to be linked to WaterUse:Storage objects to store and draw reclaimed water. The object can also simulate drainwater heat recovery.

Table:Lookupο
Lookup tables are used in place of curves and can represent any number of independent variables (defined as Table:IndependentVariable objects in a Table:IndependentVariableList). Output values are interpolated within the bounds defined by each independent variable and extrapolated beyond the bounds according to the interpolation/extrapolation methods defined by each independent variable.

PythonPlugin:SearchPathsο
Add directories to the search path for Python plugin modules The directory containing the EnergyPlus executable file is automatically added so that the Python interpreter can find the packaged up pyenergyplus Python package. By default, the current working directory and input file directory are also added to the search path. However, this object allows modifying this behavior. With this object, searching these directories can be disabled, and users can add supplemental search paths that point to libraries of plugin scripts.
