I am trying to take an existing hospital building file (idf) from Atlanta, Georgia, and simulating it with a weather file (IWEC) from Johannesburg, SA. Based on my research, Johannesburg and Atlanta should have similar climates. I didn't make any additional changes in the idf file except changing the latitude, longitude, time zone, and elevation to match Johannesburg numbers. I am encountering this severe error in which the chiller is failing. Has anybody dealt with this before? Please help
