Design your project with a greenhouse ventilation calculator

A greenhouse ventilation helps you to predict energy consumption

You can simulate online any horticultural greenhouse project all over the world with our greenhouse ventilation calculator.

Hortinergy predicts energy consumption : heating, dehumidification, lighting, cooling

You can choose your offer, create an account and start your project.

Analyse in a few minutes the energy consumption and indoor climate of your project with our greenhouse ventilation calculator.

1. How does a greenhouse simulator work?

With this greenhouse ventilation calculator you can :

greenhouse heating calculator monthly consumption
Outputs of the greenhouse ventilation calculator
  • Greenhouse energy consumption for heating, dehumidification, cooling and lighthing on an hourly, daily, monthly and yearly basis
  • Inner climate modelling (temperature, humidity) on an hourly basis like a virtual greenhouse
  • Consumption of the primary and secondary heating system and heat load-duration curve
  • Equipment sizing
  • Comparison of the solutions (annual, monthly basis)

Inputs of the greenhouse calculation tool

  • GPS coordinates of the greenhouse for the weather file
  • Greenhouse light transmission simulation with dimensions, materials and screens
  • Intended internal climate settings (temperature, humidity, water deficit)
  • Types of crop (tomato, cannabis, lettuce, strawberry…)
  • Types of greenhouse (standard, semi-closed, active ventilation, closed)
  • Heating, closed greenhouse and supplemental  lighting equipment
  • Greenhouse energy production and storage equipment
  • Climate control settings:  temperature and humidity during day/night time period, screens..

2. Methodology and reliability of the greenhouse software

A. General methodology
calculator methods
B. Different steps of the greenhouse ventilation calculator

Algorithms of the greenhouse calculator are complex. Therefore our servers need approximately 20 minutes to perform calculation to simulate your greenhouse. Then they send the reports.

C. What happens to my data in the greenhouse software ?

You are the owner of your data in all circumstances. We only use your data to simulate your greenhouse project. They are not communicated to a third party or reused in our calculations or for any other purposes.

Your data are stored for 1 year in a secured server of the greenhouse design software, then they are deleted. You keep your hands on it: if you ask for, we can delete all your data at anytime.

D. Reliability of the greenhouse ventilation calculator

The climate modelling and energy consumption calculations are performed using proven algorithms. The 10% accuracy has been validated through measurement campaigns carried out at CTIFL, Astredhor and Wageningen University (WUR) in Mediterranean, ocean and semi-continental climates in conventional and semi-closed greenhouses.

Hortinergy, our greenhouse simulation software, was developed by Agrithermic in partnership with CTIFL (French Interprofessional Technical Centre for Fruits and Vegetables) and Astredhor  (Horticultural Institute of Technology), the Agrocampus Ouest and the agricultural high school of La Cote saint André (CFPPA).
