Greenhouse Climate System Calculator.
Estimate indicative heating load, cooling capacity, ventilation rate and pad area for a commercial greenhouse. Recommends system categories only — vendor-neutral by design.
Envelope & climate
- Hydronic heating (boiler + rail/perimeter pipes) or heat-pump for lower carbon.
- Buffer tank + energy screen — 25-40% heat savings.
- Fan-pad evaporative cooling or high-pressure fog.
- Climate computer with EC/pH, CO2, VPD and screen strategies.

SeedMatchGroup is a supplier-neutral platform. We do not manufacture or resell greenhouse equipment — we help buyers specify the project correctly, open one private RFQ to qualified global manufacturers, integrators and EPCs, and match matching financing tracks.
Frequently asked questions
Simplified: Q = U x A x dT, where U is the cover heat-loss coefficient (W/m2K), A the envelope area (roof + walls) and dT the temperature difference between setpoint and design outdoor. Real projects add air-infiltration, ground losses and safety factor 1.2-1.4.
Passive-vented greenhouses typically achieve 0.7-1.0 air changes per minute at full opening. Pad-and-fan cooled greenhouses in hot climates target 40-60 air changes per hour with 1.5-2.5 m/s through-pad velocity.
No. This tool recommends system categories (fan-pad, high-pressure fog, hydronic heating, heat exchanger, humidity control) and then opens a private RFQ to qualified global climate integrators. Manufacturers are chosen by the buyer, not the platform.
