Dear all,
I think there have a bug in DOE-2.1E-119 units conversion. I use the same
simple project which include only one room. The diffrence is roof
description method. One is use WIDTH & HEIGHT, and the other is use POLYGON.
Input as follows :
===== input 1 =====
INPUT LOADS
INPUT-UNITS METRIC
OUTPUT-UNITS METRIC ..
RF01001 = ROOF
CONS = ROOF1
X = 0
Y = 0
Z = 3.2
WIDTH = 4
HEIGHT= 5
AZ= 180
TILT= 0
SHADING-SURFACE YES
..
===== input 2 =====
INPUT LOADS
INPUT-UNITS METRIC
OUTPUT-UNITS METRIC ..
Roof-poly = POLYGON
(0,0) (4,0) (4,5) (0,5) ..
RF01001 = ROOF
CONS = ROOF1
X = 0
Y = 0
Z = 3.2
POLYGON = Roof-poly
AZ= 180
TILT= 0
SHADING-SURFACE YES
..
And the results are:
===== output 1 =====
AREA WIDTH HEIGHT
SURFACE MULTIPLIER ( M2 ) ( M) ( M)
RF01001 1.0 20.00 4.00 5.00
SENSIBLE LATENT
(KBTU/H) ( KW ) (KBTU/H) ( KW )
-------- ------ -------- ------
ROOF CONDUCTION 0.798 0.234 0.000 0.000
===== output 2 =====
AREA WIDTH HEIGHT
SURFACE MULTIPLIER ( M2 ) ( M) ( M)
RF01001 1.0 1.86 -3048.00 -3048.00
SENSIBLE LATENT
(KBTU/H) ( KW ) (KBTU/H) ( KW )
-------- ------ -------- ------
ROOF CONDUCTION 0.074 0.022 0.000 0.000
However, 1.86 square metres = 20 square feet.
Thanks & Regards,
