Re: [EnergyPlus_Support] Window U-6.81 & SHGC - 0.25



The requirement is for the maximum, so you would still comply- yet you would loose points for your baseline being "too efficient"

I wonder what approaches others have taken to make their baseline be no more then required..?

For the baseline, climate zone 1B in ASHRAE 90.1-2007 requires the vertical glazing max. U-value to be 6.81 W/m2.K and SHGC 0.25, whereas the requirement for skylight is U-11.24 W/m2.K and SHGC - 0.36.

I enquired with the main E+ support website and came to know that it's not possible to model windows with a U-value greater than about 6.

I would like to know if there's any workaround for modeling the baseline window with such a high U-value or whether the baseline window can be modeled with U-value of about 6 and still comply.

Thanks,

Aber
