Hi,

I have two warning :

1. one of my zone become negative, how to solve this? * Warning * Indicated Zone Volume <= 0.0 for Zone=ATAP TAMBAHAN

2. Total wall area by ASHRAE 90.1 not same with user entered Wall class surfaces * Warning * WriteVeriSumTable: InputVerificationsAndResultsSummary: Wall area based on [>=60,<=120] degrees (tilt) as walls * ~~~ * differs ~8.9% from user entered Wall class surfaces. Degree calculation based on ASHRAE 90.1 wall definitions.

Would you please help me on this please find the file of "Nara Tipikal 57.idf" in gdrive link https://drive.google.com/drive/folder...

thank you very much regards, Budijanto Chandra

Great Denis, You always have a great solution, and you are correct. After I changed F4A4D5 to the roof, it also solved

Hi,

I have several error as can be found in "Nara Tipical 42.idf" in gdrive https://drive.google.com/drive/folder...

I have some questions:

1- about convexity, How to fix this issue?

** Warning ** CheckConvexity: Zone="R TIDUR UTAMA", Surface="88ADEF" is non-convex.
**   ~~~   ** ...vertex 3 to vertex 4 to vertex 5
**   ~~~   ** ...vertex 3=[4.06,3.13,3.40]
**   ~~~   ** ...vertex 4=[4.06,3.63,3.40]
**   ~~~   ** ...vertex 5=[3.06,3.63,3.40]

2- What the mean of error interzone surface area?

** Warning ** GetSurfaceData: InterZone Surface Areas do not match as expected and might not satisfy conservation of energy:
**   ~~~   **   Area=10.4 in Surface=B5C9E7, Zone=K IIDUR 2
**   ~~~   **   Area=4.8 in Surface=U_2D01, Zone=HALL
** Warning ** GetSurfaceData: InterZone Surface Areas do not match as expected and might not satisfy conservation of energy:
**   ~~~   **   Area=5.6 in Surface=1F431C, Zone=KM WC
**   ~~~   **   Area=10.4 in Surface=B5C9E7, Zone=K IIDUR 2
** Warning ** GetSurfaceData: InterZone Surface Areas do not match as expected and might not satisfy conservation of energy:
**   ~~~   **   Area=16.0 in Surface=7F857D, Zone=HALL
**   ~~~   **   Area=25.6 in Surface=C05674, Zone=R TIDUR UTAMA

3- I have error about number of layer

** Severe  ** GetSurfaceData: Construction DASARATAP of interzone surface 559937 does not have the same number of layers as the construction INTERIOR FLOOR of adjacent surface C680B1
**   ~~~   ** ...this problem for this pair will not be reported again.

How to solve this issues.

Thank you very much regards, Budijanto Chandra

Hi,

Please help. I have a problem when making two windows that it says, "This subsurface was not in the same plane as its base surface" I attached the idf file "Nara Tipikal 3 U.idf" in this gdrive link https://drive.google.com/drive/folder...

the error

This sub surface is missing its base surface: 
A new zone object has been automatically created for this surface.
However it is still missing a base surface.
Error:  FenestrationSurface:Detailed, U_1K03
This sub surface is missing its base surface: 
A new zone object has been automatically created for this surface.
However it is still missing a base surface.
Warning:  FenestrationSurface:Detailed, U_1K04

It has been automatically fixed.

thank you very much regards, Budijanto

Yes Richard, you are correct, the error is not appear when I reduce the supply air temperature thank you very much

great Denis thank you very much Have a nice day

Hi,

I have an error for one conditioned space: "Gross Rated Total Cooling Capacity [W] will be limited by the maximum rated volume flow per rated total capacity ratio".

The error is

** Warning ** SizeDXCoil Coil:Cooling:DX:SingleSpeed KAMAR TIDUR UTAMA PTAC COOLING COIL
**   ~~~   ** ...Gross Rated Total Cooling Capacity [W] will be limited by the maximum rated volume flow per rated total capacity ratio.
**   ~~~   ** ...DX coil volume flow rate ( m3/s ) = 5.633887E-002

Hi,

I have two questions:

1. one of my zone is not fully enclosed and there is some errors message but I dont understand the meaning
2. calculated design heat load is zero, we are here not use heating load. How to solve this error?
