I use the 'create DOE prototype building' measure to establish the model and change the u-value of the window in the simple glazeing system window material while keep the rest as default. The EUI shows a reasonable increase when I largen the u-value. However, after I change the HVAC system by applying 'VRFwithDOAES' measure. The EUI incresed a lot while the U value keep decreasing. Is there anyone meet the same problem ?

It's likely that the default VRF+DOAS system you pulled off of BCL has some incorrect curves and/or cops. Also check that the terminal units have a reasonable fan pressure and are cycling, not constant fans.

You may want to use an explicit manufacturer's system components on the BCL component library instead of the default ones built by the measure.
