Buildings that
work with physics.
From a survival shed that keeps batteries alive in July to a fully geothermal-coupled habitat that stays comfortable without mechanical cooling — every structure in this line applies the Thermakon stack to a specific use case.
Survival shed
The smallest useful unit. A weatherproof, thermally-managed enclosure designed to keep electronics, medications, batteries, and emergency supplies alive during Texas summers. Deployable off-grid. No HVAC.
Purpose-built for heat extremes. The goal: interior temperature never exceeds battery operating limit (113°F / 45°C) even on a 110°F Hill Country afternoon with no shade.

Premier
Storage shed
Scaled-up survival enclosure. Protects equipment, chemicals, wine, instruments, and anything else that needs a stable thermal environment year-round. Minimal footprint, serious thermal performance.
All-season thermal management for working storage. Target interior band: 60–80°F without mechanical conditioning. PCM buffers the daily swing. PDRC handles the solar load.

Habitat
A habitable structure engineered to remain livable without air conditioning on the hottest days in Texas. Not a claim about comfort — a claim about survivability. The Premier tier targets indoor conditions a human can work in indefinitely during a 110°F grid outage.
Full-size occupiable building with complete Thermakon envelope. Operates as a passive cooling demonstration site — every surface logged, every thermal delta documented, every claim falsifiable.

geothermal cooler
The deepest passive cooling available without a compressor. Ground temperature in the Texas Hill Country limestone at 4–6 feet remains between 65°F and 72°F year-round — even when the surface hits 110°F. Pier-integrated heat exchangers conduct interior heat to that stable ground mass. No refrigerant. No moving parts.

Pier integration
Structural piers are drilled into limestone with embedded copper or HDPE heat exchanger tubing. The building sits on the piers — heat path from interior to ground is structural, not mechanical.
- 6–10ft pier depth in Hill Country limestone
- Ground thermal mass: enormous and stable
- No pumps required — natural convection or minimal assist
- Geology assessment required before design
Performance limit
The coldest achievable interior temperature is bounded by ground temperature plus the thermal resistance of the exchange path. In practice: a well-designed system holds 72–76°F interior when ambient is 108°F+.
- Interior target: 72–76°F no mechanical assist
- Combined with PDRC + PCM: 68–72°F achievable
- USDA Web Soil Survey + bore test required first
- ERT site characterization for large installations
On the hottest day of a Texas summer — 110°F ambient, full sun, no wind — a Premier-tier habitat with PDRC envelope, PCM thermal mass, and pier geothermal coupling holds 72–76°F interior without running a compressor.
This is not a simulation. It requires proper site characterization, correct geology, and a well-executed installation. Results are logged and published. Every claim is falsifiable.
Site assessment first.
Geothermal performance is geology-dependent. We run USDA Web Soil Survey analysis and specify auger bore tests before any pier design begins.
