#### 7.1.3.27 IfcUnitaryEquipmentType

| Type d'équipement unitaire
| Einbaufertige Anlage - Typ

The energy conversion device type IfcUnitaryEquipmentType defines commonly shared information for occurrences of unitary equipments. The set of shared information may include:

- common properties with shared property sets
- common representations
- common materials
- common composition of elements
- common ports

It is used to define a unitary equipment type specification indicating the specific product information that is common to all occurrences of that product type. The IfcUnitaryEquipmentType may be declared within IfcProject or IfcProjectLibrary using IfcRelDeclares and may be exchanged with or without occurrences of the type. Occurrences of IfcUnitaryEquipmentType are represented by instances of IfcUnitaryEquipment. Refer to the documentation at IfcUnitaryEquipment for supported property sets, materials, composition, and ports.
