SEH Cost Savings

Hint: This page describes how we can reduce the cost of materials and build cost of a 1375 sf Seed Eco-Home from $60k to $20k in materials by using open source machines and materials production machines

Narrative

The way to reduce housing cost is by:

1. Optimized Design - open source blueprints, design optimization with integrated design, and open production engineering. All are required for an efficient build that exceeds industry standards.
2. Open-source compliance documentation - producing documentation and engineering reference drawings to reduce permit, plan check, and engineering costs from thousands to near zero marginal cost
3. Efficient Build - 24 person, 5 day modular swarm build that exponentiates learning
4. Open Source Machines - for construction and materials production.
5. Open Source Fuels - plastic pyrolysis for gas and diesel obtained from waste stream plastic. Followed by the full blown Solar Hydrogen Economy

If the current cost is $60k for materials for a 1375 sf 3 bed 2 bath home with 6kW photovoltaics, we can slash this cost to $20k with open source machines and materials. Total Savings in an Open Sector Enterprise are $39640.

• Seed Eco-Home Savings with Open Source Construction Machines - $4340
• Seed Eco-Home Materials Cost Reduction - $35300

It would be impossible for any enterprise to execute on the above without open source hardware, including:

1. Automated grading - cost reduction of $2k in labor. Once built, lifetime design operating costs must be considered:

This is not to mention operating costs:

1. Thermal Battery - 70% electrical consumption reduction out of the box because water heating, cooling, and hot water are 70% of all electric use..
2. Open Source Inverter - $2k savings for every 5 years lifetime of an inverter.
3. Open Source Heat Pump - $2k every 5 years for 5 year lifetime of a heat pump

Higher tech endeavors include:

1. Photovoltaics Manufacturing - currently cost is 20 cents per watt, as low as 7 cents from china

Priorities

For cost reduction based on the above, including strategic elements of public appeal and versatile applications, the priority list is:

1. Open source 3D printing in plastics, composites today
2. Open source CNC lumber mill - $10k in lumber
3. Lime Kiln and supporting infrastructure - $3k in concrete + rock unless displaced by Foundationless Foundation
