**Building Data** 

Contains the state of the 3D buildings for dynamic dta such as facade temperature or heat fluxes. It also includes information of the facade/ roof greeining system if existing. Data are stored in a 3D field with a data triple for X- , Y- and Z-Walls in each cell.

<WRAP clear></WRAP>

The Building data files are produced each main output interval (default: 60 min) and represent the general state of the building at the given model time. The dynamic output is only written in the full versions of ENVI-met (not in LITE).
