Integrated Passive Energy Greenhouse (IPEG) Plans

The Integrated Passive Energy Greenhouse (IPEG) System is a proven, real-world design that allows you to produce food year-round using nothing but natural energy.

This is not a traditional greenhouse. It is a fully integrated climate system that combines passive solar heating, earth-coupling, geothermal air exchange, thermal mass, and natural airflow to create a stable growing environment—even through cold Utah winters and intense summer heat.

Whether you are preparing for food security, reducing dependence on the grid, or simply want a greenhouse that actually works in all seasons, this system was designed to perform.

Most greenhouses overheat in summer and freeze in winter. The IPEG system is designed to solve both problems naturally by:

• Capturing and storing solar heat in winter
• Preventing overheating during peak summer sun
• Using earth tubes to moderate incoming air
• Actively managing cold air through a solar-driven chimney system
• Maintaining airflow without fans or electricity

The result is a balanced, energy-efficient growing environment that works with nature—not against it.

This digital product includes everything you need to understand and build the system:

System Explanation Booklet - A clear, easy-to-follow guide explaining how each aspect of this unique design works together to create the ideal year-round growing environment. We discuss passive energy climate regulation, thermal mass and heat storage, earth tube airflow systems, cold sink and solar chimney function, insulation and earth-coupling strategies, and more. It includes photos of our amazing IPEG.

31 Pages of Concept Drawings - These beautiful drawings include: system layouts and design visuals, greenhouse orientation and structure, climate flow and feature integration, big-picture understanding before you build.

78 Pages of Fabrication & Construction Drawings - The IPEG is constructed with a metal frame. These drawings include: detailed structural plans, dimensions and assembly details, and are shop-ready drawings for building the structure.

Our Dream Off-Grid Greenhouse

This greenhouse is the result of many years of research and dreaming. Our goal is to be able to grow plants year-round in the cold Utah winters and still grow during the heat of the summer. It was important to us that the design works with nature and does not require any costly fuels.

The Integrated Passive Energy Greenhouse combines the best passive technology into one, which results in successful off-grid greenhouse operation. The design is the right size for backyard implementation, which means fresh, locally grown food right at the point of consumption. Best of all, it is designed for ease of use and is handicap accessible.

⚠️ Important Notes - this design will not work in all climates. Adaptation may be required based on your climate, soil, snow loads, and local building codes

You’re not just buying plans. You’re getting a complete system designed to help you grow food year-round without relying on external energy sources. If you’ve ever wanted a greenhouse that actually works in every season…

This is it.
