Web-based Design & Analysis Tool

Greenhouse simulation, built for the real world.

Gebbora Greenhouse Simulator models the thermal, optical, and plant-growth performance of any greenhouse design (from a simple tunnel to a multi-span Venlo) using real hourly climate data for your exact location. Used by operators from Morocco to Mongolia, from Senegal to São Paulo.

The gap Greenhouse Simulator fills

Designing a greenhouse means balancing cover materials, heating, cooling, lighting, shading, ventilation, and crop requirements, all interacting with local climate in ways spreadsheets can't capture.

The simulation tools that do exist are locked inside universities (KASPRO at WUR, Cornell GEM, Virtual Grower at USDA), built for generic buildings (TRNSYS, EnergyPlus, OpenModelica), or sold as enterprise consulting engagements (Hortinergy, paid annual licence). The result: most greenhouse projects worldwide are designed on experience and best guesses.

Greenhouse Simulator is purpose-built greenhouse physics. Real hourly climate data. Results in under 30 seconds. From a browser. No installation, no licence, no IT department.

How it works

From design to comparison in four steps.

1

Design

Pick from the design library or shape your own. Designs, Locations, Crops, and Materials are reusable assets across every project.

Design wizard step 1 -- greenhouse geometry: span and gutter dimensions, ridge orientation along or into the main facade
2

Locate

Anchor every project to a real location. Hourly climate data follows the coordinates, not the design.

Locations library -- map-anchored sites with hourly climate sources
3

Prepare

Pick your climate source, choose engines, and tune run-time rigor before each analysis.

Prepare a run -- climate source picker, engine selection grid, and rigor knobs
4

Compare

Run scenarios in parallel. Compare designs side by side across every output dimension.

Compare A vs B -- side-by-side KPIs across every output dimension

What Greenhouse Simulator models

12+ physics engine modules running 8,760 hourly calculations per analysis.

Solar Radiation

Direct, diffuse, and PAR irradiance on every greenhouse surface, using McCree 1972 conversion and PVGIS satellite data.

Heat Transfer

Conduction, convection, and long-wave radiation through multi-layer cover assemblies with U-value calculation.

Crop Transpiration

FAO-56 Penman-Monteith and Stanghellini models for evapotranspiration, VPD, and stomatal conductance.

Light & DLI

Photosynthetically active radiation, Daily Light Integral classification, and supplemental lighting analysis.

Energy Loads

Heating and cooling demand, fan & pad performance, fog/mist evaporation, and energy balance across all 8,760 hours.

Shading & Screens

Up to 4 motorised shading/energy screen layers with configurable control strategies and manufacturer material data.

One scrolling Results page. Every output in context.

Indoor snapshot, growing season, DLI, heating vs cooling, energy mix -- all on one page you can scroll, share, and compare.

Indoor Snapshot

Hour-by-hour indoor climate -- temperature, humidity, VPD, and PAR for the location and design.

Growing Season

Active growth hours, suitability windows, and a season-long heatmap for the crop you picked.

DLI & Roof

Daily Light Integral classification, roof transmission, and PAR with the cover and shading you configured.

Heating vs Cooling

Heat and cool loads side by side, monthly seasonality, and supplementary-system contribution.

Energy Mix

Annual energy mix and per-load breakdown -- where every kWh goes.

Single scrolling Results page -- indoor climate, growing season, DLI, heating-cooling, and energy mix

Audit-ready output

Every analysis ships as a 10-20 page PDF.

Performance grades, calendar heat maps, transpiration sizing, full-spectrum charts, formatted, paginated, and downloadable in one click. Share with stakeholders. File for the audit trail.

Export PDF Report modal -- configurable title, generator, notes, confidentiality, and QR code

Investors & DFIs

Validate a project's climate assumptions and energy bill before committing capital. The same model the engineers use, with a methodology you can audit.

Why Greenhouse Simulator

Purpose-built where others adapt.

Web-based, no install

Open a browser and go. No desktop software, no university licence, no IT support needed.

Purpose-built for greenhouses

Crop transpiration, PAR/DLI, evaporative cooling, shading screens, not a generic building energy tool.

Real climate data

Hourly irradiance from PVGIS (using SARAH-2/3 satellite radiation), Open-Meteo, and ERA5 reanalysis. Location-specific, 10 to 40 years of history. Sentinel-2 multispectral integration coming soon.

Transparent methodology

Every equation, material source, and crop reference is documented and cited. Check our work.

Multi-engine simulation

12+ physics modules covering radiation, heat transfer, transpiration, DLI, VPD, CO₂, and energy.

Accessible pricing

Pay per analysis, not per seat or per year. 250 free credits on signup and 180 refreshed every month. Regional pricing from 0.35x to 1.00x via Paddle: a full design run typically costs USD 2 to USD 5 in tier-3 markets.
