Sun & Steel

Sun & Steel is the companion app for growers and builders running greenhouses, high tunnels and steel buildings across North America.

PLAN BEFORE YOU BUILD Four planning tools that run on real engineering data, not rules of thumb:

Heating cost. Pick your region, structure and cover, set the temperature you want to hold, and see what a season actually costs. Built on heating degree day data for 241 regions across Canada and the United States.

What can I grow. Set the temperature you can afford to hold and see which crops survive it, drawn from a database of more than 2,500 plants. It also shows what each extra degree buys you, so the trade between heating and harvest is in front of you.

Design wind speed. The three second gust your structure has to stand up to, by region. Canada converts the National Building Code hourly wind pressure; the United States uses the ASCE 7 basic speed.

Permits. Where to start by jurisdiction, which code governs, who decides, and the things that catch people out.

DESIGN IT IN 3D Build a greenhouse to size on your phone. Choose the structure, tier, cover and length, set your location so the climate shapes the recommendations, and watch the model update as you go. Save designs to your account and open them on any device.

RUN IT DAY TO DAY Connect climate, irrigation, lighting and ventilation equipment, group it by zone, and control it from anywhere. Ask Sunny watches the forecast and handles venting, watering and climate on its own, with the reasoning shown so you always know why something ran.
