We frequently speak about Energy ADE modules like "Building physics module" or "Energy systems module", but formally speaking the UML model has no modular structure. This at least hinders the maintenance of the data model.
Therefore, for a first official version a number of sub-folders should be integrated in the main folder EnergyADE of the UML model:
- EnergyADE Core
- Building Physics
- Occupance
- Material and Construction
- Energy systems
- Time series and schedules
In each of these sub-folders the corresponding UML elements and diagrams are aggeegated. It is debatable whether this modular structure of the conceptional model is also reflected in the GML encoding (separate namespaces and XML-schema files for different modules). I personally strongly prefer to stay with one Energy ADE namespace and one schema file.https://git.rwth-aachen.de/energyade/citygml-energy/-/issues/119How to specify U-values at building scale?2017-11-27T09:10:03+01:00Moritz Robert LausterHow to specify U-values at building scale?*Created by: oliviertournaire*

I am wondering how it is possible to define U values at building scale only. Let's say that a building is modeled in LOD 0 (lod0Footprint + measuredHeight) or in LOD 1, it can be interesting for some simulation tools to define a single U value for the walls and / or the ground and / or the roof.
I can use several `Construction` instances and attach them to the building, but how can I differentiate them (except using a convention that fills the `gml:name` or `gml:description`)?

Up to know, we've only considered the primary energy and CO2 emissions for the operational phase of the building. More and more urban analyses consider also the "grey energy" and the "embodied carbon" to take some decision.
Here is a proposal discussed with Alessio, to integrate (step by step) the construction/refurbishment phase in our Energy ADE:
In the Construction Module:
- introduction of the new attribute EmbodiedCarbon in the class "SolidMaterial" : optional, measureType (generally kgCO2/m3 or kgCO2/kg), definition : CO2 equivalent emissions caused by the fabrication and transportation on site of the material.
- introduction of the new attribute EmbodiedEnergy in the class "SolidMaterial" : optional, measureType (generally J/m3 or J/kg), definition : Primary energy consumed for the fabrication and transportation on site of the material.
- introduction of the new attribute LifeSpan in the class "Construction" : optional, TimePeriod type (or Time length), definition: Period of service life, including the construction/installation date and the expected end of life.
- introduction of the new attribute LifeSpan in the class "Layer" : optional, TimePeriod type (or Time length), definition: Period of service life, including the construction/installation date and the expected end of life.
In the Energy and System Module:
- introduction of the new attribute LifeSpan in the class "EnergyConversionSystem", "EnergyDistributionSystem" and "_StorageSystem" : optional, TimePeriod type (or Time length), definition: Period of service life, including the construction/installation date and the expected end of life.

Optical properties (reflectance, transmittance, emittance, absorptance etc...) are presently spread off in different objects of the Material Module (Construction and Glazing), with different level of details (distinction hemispherical/normalIncidence in Glazing).
For more readibility and flexibility, it would be interesting to pick out all optical properties and gather them in a single object "OpticalProperties", possibly assigned to Construction or LayerComponent.
In this case, the specification of a "GlazingObject", hybrid object between a layer and material, would not be required anymore. Instead, we could only distinguish Materials between Gas and SolidMaterial. The transparence characteristic would come only from the OpticalProperties...

A widley used property for the calculation of transmitted solar gains through a window is the g-value. Right now it seems that it is missing in the schema, correct me if I'm wrong.
The g-value is comparable to the uValue, since it is typically calculated for the whole window and not single panes.
Considering that, I would suggest to implement the gValue in _Opening, but I'm not a expert in UML Design.
Also it seems that thermal properties like conductivity, density etc. can't be set for glazing, again: correct me if I'm wrong :)

Presently, for the identification and management of the Construction objects, no name / description exist.
- it would be useful to add an attribute name[CharacterString].
for instance: "28cm brick wall".
Concerning the Material, What contains precisely the attribute referenceURI? Can we get the material name through it? or it is just an reference id?
