Design your project with a greenhouse calculator

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

You can simulate online any horticultural greenhouse project all over the world with our greenhouse calculator as :

inner climate on an hourly basis during a typical year,
energy consumption : heating, dehumidification, lighting, cooling and ventilation.

A greenhouse calculator helps you to predict heating, cooling, dehumidification, lighting and ventilation.

Hortinergy is an online calculator. You can choose your offer, create an account and start your project.

1. Design your greenhouse project

With this greenhouse calculator you can :

Calculate energy consumption and expenditures: heating, cooling, lighting, dehumidification and ventilation
The model includes specific greenhouse parameters: light transmission simulation, crop transpiration, equipment, heating system, climate settings…
Hortinergy incorporates modern technologies such as semi-closed greenhouse, closed greenhouse, active ventilation, supplemental lighting…
Model the inner climate (temperature, humidity) like a virtual greenhouse.
You can simulate new projects as well as existing greenhouses.

Outputs of the greenhouse simulator

Greenhouse energy consumption for heating, dehumidification, cooling, lighting and ventilation 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 calculator

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)
Type of crop: tomato, cannabis, lettuce, strawberry…
Type 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 simulator

A. General methodology

B. Different steps of the greenhouse 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 design 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 third parties 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

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