Re: HELP!!!! DESIGNBUILDER will not open on my machine!

Hi, I would suggest to try to repair DesignBuilder installation by clicking on the Repair option available at Windows Control Panel. If this does not fix the issue then you may need to try the following steps. If the session was suddenly closed then it may have corrupted some of the software session...

Re: Temperature Setpoints !!!!

Hi Shina,

DesignBuilder uses the E+ object ThermostatSetpoint:DualSetpoint to define the temperature setpoints.

Re: Multiple simulations

Hi,

You can only export the IDF if the DesignBuilder simulation runs successfully first. Please confirm if your model runs a simulation without any problems.

Re: light diffusers

Hi If you are referring to something similar to a light shelf then this may be achieved by using a Component block Standard type near the window and change the material Specularity value to 0 in order to model a purely diffuse reflection. https://designbuilder.co.uk/helpv6.0/#SurfaceProperties.htm B...

Re: CFD simulation

Hi

As described on the program help the airflow rates through open windows, vents, doors and holes can be calculated using the Calculated natural ventilation option.
You can find a webinar recording demonstrating the process involved at: https://www.youtube.com/user/DesignBuilderUK

Re: kWh electricity or refrigerant

Yes, the District Cooling output on the End uses table refers to the electricity consumption in kWh but it is also the cooling load because of the COP=1.

Re: Daikin VRF outdoor unit template

Hi Frank, VRF Daikin models have not been implemented in DesignBuilder v5.5 and v6.0. However you can build the Daikin, or any other manufacturer, performance curves using DesignBuilder curve generation spreadsheets that are available to download at https://designbuilder.co.uk/download/release-softw...

Re: Merge Zone error

Hi, I believe you are running an old DesignBuilder version and this has been improved in the latest release v6.0. To fix the issue on older versions you will need to navigate to the Zone HVAC group ( at Detailed HVAC interface) and update the zones selected. The merged child zone cannot be included ...

Re: Zone HVAC Energy Consumption

Hi, I'm not sure if you are using DesignBuilder but the principle here is the same as running directly on E+. The results you are getting seems to be expected in hot climates. I would suggest to study the zone heat balance results to understand the cause of the cooling energy and adjust the model in...

Re: Zones not getting created

Hi,

It looks like the Automatic zoning model option is switch off. Turning this option back on or running the Rezone block command accessed from Tools menu will rezone the block.

Re: How to create building blocks from outline blocks ???

Hi, If the Outline block intersects any existing Building block then the conversion will fail. The Outline bock intersection needs to be removed eg. using the cutting tool. The Ghost block tool can be used to identify the intersection. https://designbuilder.co.uk/helpv5.5/#GhostSelectedBlocks.htm BR...
