# Climate Zones > Provider: [DutchGreenhouses](/) Climate zones are the broad climatic regions a greenhouse project can be built in, each imposing a different dominant constraint on the design. Latitude, humidity, wind and snow load decide the structure, covering, screening, cooling and lighting strategy long before crop choice or budget does. ## Facts | Property | Value | |---|---| | Zones covered | 7 zones | | Determined by | Project location categorical | | Structural inputs read from the site | Wind load and snow load categorical | | Dominant constraint | Differs per zone — winter light, heat, humidity or daylight hours categorical | | What transfers between zones | The design method, not the drawing categorical | Greenhouse horticulture # Climate zones. The same Venlo bay behaves very differently at 52 degrees north than at 24. ## What travels is the method, not the drawing ## The Dutch greenhouse is not a universal product It is an answer to a specific climate: mild, grey, damp, and short of light for five months of the year. Ship that exact specification to the Gulf and you have built a solar oven. Ship it to Kazakhstan and the roof will not hold the snow. Ship it to Java and the vents will be open all day removing nothing. What exports well is not the drawing. It is the way of arriving at one. ## Climate decides which problem you are actually solving Every greenhouse fights something. Which thing depends entirely on where it stands. In the Netherlands the enemy is darkness — heat is expensive but tractable, and winter light is the ceiling on production. In the Gulf it is heat, and every method of removing it spends water. In the tropics it is humidity, and the usual tool for that stops working. Near the poles it is daylight hours, to the point where lamps stop being supplemental and become the production system. Same crop, same structure family, four different machines. ## Some of it is not negotiable Wind and snow are structural loads, and they are read off the location before anything else is decided. A design certified for the Westland is not certified for Almaty, and no amount of climate equipment inside compensates for a frame that was never dimensioned for the load on the roof. That part of the specification is set by the site, not by preference or budget. ## And some of it is counter-intuitive The expensive mistakes in export projects are rarely the obvious ones. Cooling a desert greenhouse by evaporation works, and it consumes water in the place with least of it. Opening the vents in a tropical greenhouse moves air and removes almost no moisture, because the air outside is already full. A mild Mediterranean winter tempts everyone into an unheated house, and then the January nights arrive with condensation and disease. Each of those is a physical result, not an opinion, and each one is cheaper to learn on this page than on a site. ## How we approach it DutchGreenhouses® designs from the location’s real climate profile — including the extremes it sees rarely, because those are what a facility gets judged on — and works backwards to the structure, climate systems, screens, water and light. Tell us where you are building. That single answer changes more of the specification than anything else you will tell us. By zone ## Find where you are building. ### Temperate maritime Netherlands, UK, northern France, New Zealand. Light is the ceiling. ### Continental Central Asia, eastern Europe, Canada. Both extremes, one building. ### Arid & desert The Gulf, North Africa, the American southwest. Cooling costs water. ### Mediterranean Spain, Turkey, Morocco, coastal California. Mild is not the same as easy. ### Tropical & humid Southeast Asia, equatorial Africa, the Caribbean. Venting stops working. ### High-altitude tropical Kenya, Ethiopia, the Bogotá savanna. Where the world’s roses grow. ### Cold extreme & polar Nordics, Canada, Iceland. Daylight, not warmth, is the limit.

The same specification becomes a solar oven in the Gulf, is not dimensioned for Central Asian snow load, and vents uselessly in saturated tropical air. The design method transfers between climates; the drawing does not. **Which climate factor changes a greenhouse specification the most?** Latitude and humidity together. Latitude sets the winter light available and therefore the lighting and screening strategy; humidity decides whether ventilation can remove moisture at all. Wind and snow load are read separately and set the steel. **Can one greenhouse design serve several climate zones?** The structural family usually can — Venlo bays are built in all seven zones. The covering, screen package, cooling method, water treatment and lighting differ enough that the finished facilities behave like different machines. **What decides the specification first?** The build location. It sets the structural loads, the dominant climate constraint and the available water before crop choice or budget enter the conversation. ## Related [Temperate Maritime](/climate-zones/temperate-maritime.md) · [Continental](/climate-zones/continental.md) · [Cold Extreme & Polar](/climate-zones/cold-extreme.md) · [Mediterranean](/climate-zones/mediterranean.md) · [Arid & Desert](/climate-zones/arid-desert.md) · [Tropical & Humid](/climate-zones/tropical-humid.md) · [High-Altitude Tropical](/climate-zones/high-altitude-tropical.md) · [Greenhouse Horticulture](/greenhouse-horticulture.md) · [Greenhouse Construction](/greenhouse-construction.md) · [Climate](/climate.md) · [Screening](/screening.md) · [Growlights](/growlights.md) · [Performance & Outcomes](/performance.md)
