CLEANhomes

Energy Included. For Life.

Starting from $200K

Energy Bills are optional

CLEANhomes are carefully engineered and skillfully built to use 70% less energy.

Each CLEANhome receives its annual energy allocation. For Life.

CLEANhomes are built to the CLEANstandard... at the same price as ordinary code-built houses.

Finally, energy bills are optional.

You can keep paying energy bills.

Or you can choose EnergyFreedom.

Finally, energy bills are optional.

THE CLEANstandard

6 Standards.
No Compromise.
No Exceptions.

From: THE CLEAN STANDARD: The Dark Truth Behind Your Energy Bill

01⚡

Reduce Energy Demand

70% Less Energy

Advanced building science and methods effectively eliminate most wasted energy; energy bills shrink and comfort grows.

02✅

Verify Performance

HERS Rating Certified

The performance of each CLEANhome is tested and verified, not just promised.

Real Data = Real Results.

03🛋️

Comfort is Automatic

No Chasing Thermostats

Forget shutting off cold rooms or living with cold floors. CLEANhomes delivers consistent comfort in every corner, all year long.

04🏗️

Build to Last

Quality for Longevity

Materials, mechanical systems, and appliances are selected for performance, durability and long-term value. No 'builders grade' here.

05☀️

Use CarbonLessEnergy®

Goal: Zero Carbon Footprint

CLEANhomes are powered without carbon-based fuels wherever possible. Cleaner air. Lower impact. A healthier, safer future inside and out.

06💰

Affordable

Priced for Your Market

CLEANhomes are competitively priced for each local market, proving that energy efficiency is now affordable.

The CLEAN Trilogy

01

CLEANhomes

Built to the CLEANstandard

Use 70% less energy.

Energy Included. For Life.

02

CarbonLessEnergy®

On-Site Power Generation

Power is supplied where it is needed.

No more carbon fuels.

03

EnergyEquity™

The Forever Asset

Net Present Value (NPV) of future energy savings.

Worth more than the price of any CLEANhome!

What is a CLEANhome?

A CLEANhome uses 70% less energy and includes the energy it needs every year. For Life. At the same price as an ordinary house!

Your CLEANhome starts with no energy bills required.

Use more than its annual allocation, pay fairly; use less, receive credits.

CLEANhome vs Average New House

The same price. A very different month.

MetricCLEANhomeAverage New House
Annual energy use~7,000 kWh (included)~21,000 kWh
Warranty mentalityPerformance-based, 5 years minimumMinimal, 1 maybe 2 years
Price$500,000$500,000
Mortgage Interest5.5%6%
Mortgage Pmt$2,271$2,398
Energy Bill$0$200
Water Bill$60$100
Total Monthly$2,331$2,698

That's ~$367/mo savings – over $4,400/yr!

CarbonLessEnergy®

A new ethos: we can power almost everything without burning carbon fuels.

On-site Power Generation: Power is supplied where it is needed - not transmitted from miles away.

Cleaner air. Lower impact. A healthier, safer future inside and out.

EnergyEquity™

The energy your CLEANhome needs and doesn't use is EnergyEquity™.

EnergyEquity™ is the Net Present Value (NPV) of the future energy savings built into every CLEANhome. Because a CLEANhome uses 70% less energy than a code-built house - and includes the energy it needs - those avoided costs are a real, calculable asset.

It's equivalent to needing ~$600K in the bank to pay for a code-built house's energy bills for the next 60 years.

HorizonCumulative Energy Bills AvoidedEnergyEquity™ (NPV)
30 years~$169,000~$127,568
60 years~$1,000,000+$558,106
100 years~$10.075M$3,043,577

EnergyEquity™ is usually worth more than the price of a CLEANhome itself.

Core Values

01

Ethics

Doing the right thing.

02

Integrity

When no one is watching.

03

Stewardship

For others first.

Once you experience what Ethics, Integrity, and Stewardship builds, you'll never want to live in a code-built house again.

The Journey

2006

The Spark

A persistent $250/month energy bill triggers one question: Why does my home require so much energy?

2006 – 2009

The Research

Over 10,000 hours of research into building science and methods.

2009

Proof of Concept #1

8,000+ ft² model home. Projected Savings: 75%. Actual: 80.21%

2010

Proof of Concept #2

1,200 ft² addition. Projected Savings: 75%. Actual: ~85% - WITH NO SOLAR

2010 – 2019

The Cost Barrier

Ten years of re-engineering to bring costs down from 25% premium to market competitive.

2019

Price Parity

CLEANhomes at or slightly below conventional market prices.

Douglas K Shamlin

Founder & Chief Systems Engineer

  • Former U.S. Navy Officer
  • Qualified Nuclear Mechanical Operator
  • B.S. Mathematics, North Carolina State University
  • M.S. Systems Engineering, Naval Postgraduate School
  • Information Systems Security & Systems Engineering, NSA

A former U.S. Navy officer, he began his career in the Navy's Nuclear Power program and qualified as a Nuclear Mechanical Operator before finishing his degree in Mathematics from North Carolina State University and subsequent commissioning as an officer. He later served in Information Security Management roles for the Navy which included an Information Systems Security Engineering Senior Program Manager position at the National Security Agency. Douglas holds a Master of Science in Systems Engineering from the Naval Postgraduate School.

Douglas' work in energy-efficient construction grew out of a systems-level investigation into why modern homes remain expensive to operate despite decades of technical advancement. His research led to the development of THE CLEAN STANDARD, a practical framework for designing and building homes that dramatically reduces energy demand and improves comfort, durability, and affordability.

Actuarial Notes

  • Energy savings projections assume 5.7% annual energy cost inflation based on recent US trends (2024 – 2026: 5.66%, 6.16%).
  • Baseline: US average household energy consumption (~20,855 kWh/yr) and average cost (~$2,256/yr), 2024 data.
  • ROI figures are illustrative, based on stated assumptions, and vary by location, usage, and rate changes.
  • 100-year figures are multi-generational projections for illustrative purposes.
