IDA resources
This form contains the IDA-resources currently or previously used in a project. If, for example, an Internal wall with insulation is chosen somewhere in the building, the IDA resources Internal wall with insulation, Gypsum, Air in 30 mm vertical gap and Lightweight insulation will appear in the list. (The Internal wall with insulation contains references to a set of material resources).
A change made in an IDA resource at the building level applies to all the instances in the building where it has been used. If, for example, the density is changed for the IDA resource concrete from 2300 kg/m3 to 2400 kg/m3 at the building level, this change will influence all walls and floors in the building that contain concrete.
Resources that have no references to them (aren’t used) can be deleted. Right click to check where a resource is used. The button "Remove unused resources" in the upper right corner removes all unused resources.
Resource objects can also be stored in separate resource documents that are accessed by pressing the Import... button.
Resource objects are frequently created from database objects. A list of all available objects can be found in the Database objects in IDA Indoor Climate and Energy.
