Re: Can daylight simulations run on Simulation Manager?

Hi, > Can daylight simulations be performed in the simulation manager, or is it only for Energyplus simulations? At the moment Simulation manager is only used for E+ simulations. > And do I need a another seperate licence for the simulation manager. V5.5. No, a 2nd license is not required. BR, Luis

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: 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.

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.

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...
