The Greenhouse Energy Guide Simulator is a an online tool for calculating the effects of different (combinations of) renewable energy sources on the environmental foodprint, expressed in energy consumption, crop performance, variable costs and environmental impact.

Users can create a digital twin of an existing greenhouse or design a future greenhouse, where they can fully customize all available parameters to their own insights.

The simulator can be used in 2 different CO2-emission according to the European Union Emissions Trading System (EU ETS). This means that the CO2-emission from fuel combustion is counted as contribution to emissions (each fuel has its own conversion factor per unit of fuel). Emissions related to import of commodities to a greenhouse (e.g. electricity, heat, fertilizer) are not attributed to the greenhouse enterprise. The other way around, savings on CO2 emission by third parties because of services from a greenhouse (heat, electricity or CO2 supply) are not subtracted from the greenhouse CO2 emission.

With the simulator, users can define different scenarios of greenhouse concepts for a number of geographical locations and crops. The simulation model produces benchmark figures and by comparing the results of different scenarios, a customized sensitivity analyses can be made.

The simulator has 2 user-modes:

• Anonymous mode

• Registered user mode

The anonymous mode is available without registration and allows users anyone to create and simulate a scenario, where the last results are compared to the previous resultsscenarios, with an overview of the results of the last and previous previous simulation. Anonymous users are able to change basic model parameters only.Registererd the basic scenario parameters where defaults are used for the advanced parameters.

Registered users can create, save and compare multiple scenarios and have access to the advanced model scenario parameters.

Registered users

Registered users must logon with the “lock” button at the top right and enter

...

Once logged on the main screen appears with the saved scenarios list on the left. Next step is to create a new scenario with the ADD button.

...

A dialog appears where a crop and location can be selected

...

Anonymous users

In the anonymous mode the main screen shows drowdown lists where a crop and location can be selected for a new scenario.
