Question-and-Answer Resource for the Building Energy Modeling Community

Hi Julio, why don't you download the latest version of design builder? This way you can model ASHPs. https://designbuilder.co.uk/download/release-software
regarding your error message: It would be helpful to see the HW secondary loop schematic. You HVAC system is sharing energy on the condenser loop between the chilled water and hot water loops. Each of these loops serve chilled water and hot water coils in AHUs, correct? Why are you connecting the HW and CHW loops to heat exchangers? they should be able to connect directly to the AHU HW and CHW coils. I would remove the HW secondary loop and make direct connections. If that doesn't work, provide some more images of the HW secondary loop and I can help further.
