Hello,

I'm concerning about how to define in a multifamily building different PV systems?

For example: - Flat 1 (Thermal zone 1) have 2 PV panels on the roof; - Flat 2 (Thermal zone 2) have 1 PV panel on the roof

I defined each flat as a separately thermal zone.

There is any option to aggregate PV panels for a thermal zone or even to a set of thermal zones?

I tried to simulate this small example in Designbuilder and E+, but both have no option to aggregate PV systems to specific Thermal zones in ElectricLoadCentre.

Thanks in advance.

The Electric load center feature that includes the PV generator is a building level object ( in DesignBuilder terms).

However, it is possible to generate outputs for different Electric load Center objects.

My suggestion would be to:

1.Create two Electric Load Centre objects, for Flat 1 and Flat 2, and group the PV panels accordingly; image description

2.Using DesignBuilder EMS scripting module, add the extra output Electric Load Center Produced Electric Energy.

More detailed instructions to add extra outputs can be found on DesignBuilder Program Help. https://designbuilder.co.uk/helpv6.0/...

3.Then use DesignBuilder Results Viewer tool to see results.
