CityGML Export

Implement CityGML and Energy ADE Export

[PRemmen]

We can't support every option to model a building (or multiple buildings) in CityGML. We should be compliant with this guide:

[PRemmen]

In TEASER we will use LOD2

LOD1: Only Solid, and Solid represents boundaries, only horizontal roofs and vertical walls

LOD2: Solid + boundarys represent the Building, tilted roofs and walls allowed

[PRemmen]

For each boundary surface of a wall we need to set an empty window to reference this in the thermal boundary surfacecomponent

<bldg:boundedBy>
                <bldg:WallSurface gml:id="b_TestBuilding_d">
                    <bldg:lod2MultiSurface>
                        <gml:MultiSurface>
                            <gml:surfaceMember xlink:href="TestBuilding_d"/>
                        </gml:MultiSurface>
                    </bldg:lod2MultiSurface>
                    <bldg:opening>
                        <bldg:Window gml:id="TestBuilding_d_win"/>
                    </bldg:opening>
                </bldg:WallSurface>

</energy:boundedBy>

still to do: find a efficient way to call all these classes

[PRemmen]

For each boundary surface of a wall we need to set an empty window to reference this in the thermal boundary surfacecomponent

Maybe one solution is to decouple the geometric and semantic information. e.g. we do not model windows etc. but we have semantic information about it.

[PRemmen]

Still to do, correct interpretation of g_value and other window properties

[PRemmen]

Currently the EnergyADE is not able to store information like thermal conductivity for Glazing, this will change in the next release

I think the major functions are merged with PR #45 so i close this one.

Reopen if necessary
