Dear All,
I have a problem that as I have a relatively high heat loss from window as shown in the table extracted from the html file. The window heat gain removal is around half of the window heat gain addition. The location is Singapore where it is hot and humid. I have also checked that the time that the outdoor air temperature is lower than the setpoint is less than 2 hours for the entire year. May I know what can cause the Window Heat Removal? This is probably causing me to obtain results that show that having a 50% window to wall ratio will have a cooling load lower than having no windows at all.
Thanks for any inputs.
