Re: [EnergyPlus_Support] BLAST buiding geometry data generation
There are no known problems with the HBLC geometry data, but I have some
suggestions or explanations which might help. (Thanks to help from an unnamed
BLAST/HBLC expert!)
1. The default roof and floors which are added to non-rectangular zones may be
causing some confusion. HBLC will put an equivalent area roof surface above
the zone and another equivalent surface as the floor. This allows the user to
put in complex looking wall geometries and HBLC to determine the correct
roof/floor area and enter in the one rectangular equivalent surface.
The user can go into HBLC double-click on the roof and bring up the roof/floor
input screen. Then uncheck the auto calculation and then enter the coordinates
for the roof and floors by hand to explicitly place them geometrically correct.
But I would not do this until all of the zones have been inputted.
2. Zone origins are 0,0,0 unless the user moves the zone away from the corner
of the drawing palette. Then the zone origin will have some arbitrary value
per the location on the screen. But that should not be a problem, the surface
coordinates should be correct.
