Afternoon Discussion
| First proposals Energy ADE |
R. Kaden - Draft Energy ADE of TU Munich
This EnergyADE is "EnEV-conform" (EnEV = German thermal regulation). The present scope is only the calculation of space heating and cooling demand
Why don't you keep the full information concerning the boundary surface orientations? |
R. Nouvel - Draft EnergyADE of project SimStadt
This EnergyADE is designed first for steady state simulation (yearly, monthly balance) but may be extended for dynamical simulation (hourly time step). The present scope is only the calculation of space heating / cooling and domestic hot water demand
Where do you store your simulation results or measured consumption data? Answer: in the EnergyUse class. |
| Open discussion |
What is the scope of the EnergyADE ?
|
Modelling of energy infrastructure (District Heating System etc.)?
|
Which parameters should we store for the HVAC systems in CityGML, e.g. to match the different data requirements of the different HVAC models?
|
Should we import/convert/store everything into CityGML?
|
| Working groups |
Synchronised with development of CityGML 3.0 on Materials.
See also projects "extra-Energy" around. May lead to a "Building occupant ADE".
