LEED Certified Home Construction in Boise, Idaho
LEED stands for Leadership in Energy and Environmental Design. It's the world's most widely recognized green building certification system. It's a third-party verification that your home meets rigorous standards for energy efficiency, water conservation, material selection, and indoor environmental quality.
EarthCraft Construction built Idaho's first-ever LEED-certified single-family home. It was a straw bale residence that earned LEED Gold certification and won the 2010 Mayor's Design Excellence Award. That expertise continues to guide every project we undertake.
What Is LEED Certification?
LEED is administered by the U.S. Green Building Council. It provides a framework for healthy, efficient, and cost-saving green buildings. For homes, LEED for Homes certification evaluates energy and atmosphere, water efficiency, materials and resources, indoor environmental quality, location and transportation, sustainable sites, and innovation and design.
Projects earn points across these categories. The total determines certification level:
Certified is 40 to 49 points
Silver is 50 to 59 points
Gold is 60 to 79 points
Platinum is 80 or more points
Why Pursue LEED Certification?
Third-Party Verification
Anyone can claim a home is "green." LEED provides independent verification that your home meets documented performance standards.
Higher Resale Value
LEED-certified homes command premium prices due to lower operating costs, healthier indoor environments, and growing buyer demand for sustainable homes.
Lower Operating Costs
LEED homes use 20 to 30 percent less energy and 30 to 50 percent less water than conventional homes. Over 30 years of ownership, this saves tens of thousands of dollars.
Better Indoor Air Quality
LEED requirements for ventilation, low-VOC materials, and moisture control create healthier indoor environments.
Environmental Responsibility
As Jon puts it, "You can lay in bed at night and feel good about the fact that you did something good for the environment." LEED certification demonstrates that commitment. You used fewer materials, you're using less energy, and you have fewer carbon emissions.
Incentives & Recognition
Some jurisdictions offer tax incentives, expedited permitting, or density bonuses for LEED-certified projects.
Our LEED Experience
Idaho's First LEED-Certified Single-Family Home
In 2010, we completed Idaho's first LEED-certified residence. It was a straw bale home on Boise Avenue that earned LEED Gold certification. The project demonstrated that straw bale construction could meet the most rigorous performance standards while creating a beautiful, comfortable home.
This project won the Boise Mayor's Design Excellence Award and remains a flagship example of what's possible when traditional building wisdom meets modern performance standards.
Multiple LEED Gold Projects
Since that first project, we've completed multiple LEED Gold certified homes using both straw bale and conventional framing, proving our expertise across construction methods.
Continuous Standards Compliance
By utilizing natural building components alongside modern building materials, EarthCraft builds homes to Energy Star and LEED Gold certification while continuing to meet US Green Building Council and Department of Energy standards of green home design and construction.
LEED for Homes: The Categories Explained
Energy & Atmosphere (38 points possible)
This is typically the largest category. Points are earned through high-performance building envelope, energy-efficient HVAC systems, renewable energy systems like solar, energy modeling and verification, and efficient appliances and lighting.
Our straw bale homes with R-45 walls and passive solar design excel here. A straw bale home comes closer to net-zero building design than any of our options.
Water Efficiency (15 points possible)
Points are earned through high-efficiency fixtures (toilets, faucets, showers), waterefficient landscaping, rainwater harvesting systems, irrigation efficiency, and indoor water use reduction.
Materials & Resources (10 points possible)
Points are earned through locally sourced materials, recycled content materials, certified wood products like FSC lumber, construction waste management, and material efficiency.
Our use of locally sourced straw (a readily available renewable resource that regenerates annually), regional timber, and careful material selection addresses this category naturally.
Indoor Environmental Quality (21 points possible)
Points are earned through ventilation systems like ERV or HRV units, low-VOC paints and finishes, formaldehyde-free materials, moisture control strategies, radon protection, and HVAC system design.
This is where our commitment to healthy homes shines. Given the organic wheat straw, natural wood, and low-VOC coatings we use, our homes showcase healthy indoor environmental qualities.
Sustainable Sites (10 points possible)
Points are earned through site selection (avoiding sensitive lands), minimizing site disturbance, landscaping with native plants, stormwater management, and heat island reduction.
Location & Transportation (10 points possible) Points are awarded based on property location relative to services, transit, and community amenities.
Innovation (6 points possible)
Bonus points for innovative strategies or exceptional performance beyond standard requirements.
The LEED Certification Process
Phase 1: Planning & Registration
Register project with USGBC, select LEED for Homes rating system, engage LEED Green Rater (we coordinate this), and establish performance goals.
Phase 2: Design
Integrate LEED strategies into design, do energy modeling to optimize performance, select materials aligned with LEED credits, and plan documentation.
Phase 3: Construction
Quality control throughout construction, material documentation and verification, progress inspections by Green Rater, and testing like blower door and duct leakage.
Phase 4: Verification & Certification
Final inspection and testing, documentation submission to USGBC, review and certification decision, then issuance of LEED certificate and plaque.
Total timeline adds 2 to 3 months to the project for documentation and verification.
LEED vs. Other Green Certifications
LEED
Most recognized, comprehensive, third-party verified, national standard. More expensive ($3,000 to $8,000 in certification costs) and requires more documentation.
Energy Star
Lower cost, focused on energy, widely recognized. Less comprehensive than LEED
Passive House
Extremely rigorous energy standards, excellent performance. Very demanding with limited recognition outside enthusiast circles.
Living Building Challenge
Most rigorous green certification available. Extremely difficult to achieve and expensive.
Our take is that LEED provides the best balance of rigor, recognition, and achievability for most projects.
How Much Does LEED Certification Cost?
Certification Fees
$3,000 to $8,000 depending on project size and certification level.
Construction Costs
LEED strategies may add 5 to 10 percent to construction costs, but not always. Many LEED credits cost nothing extra. Proper orientation, efficient design, and careful material selection don't increase costs. These are things we do anyway because they make sense.
Return on Investment

Long-term Value
LEED homes have higher resale values and lower operating costs, providing financial returns beyond energy savings.
When coming to an estimate for a custom home, it's less about the square footage than it is about how the home is built. We offer long and short term cost-saving solutions to make your LEED home a reality.
LEED Without the Paperwork
Some clients want the performance of a LEED home without the documentation burden and certification costs. We call this "LEED-equivalent" construction.
We design and build to LEED standards, incorporating all the performance strategies, but skip the formal certification process. You get the same high-performance home at lower cost.
However, without certification, you lose third-party verification, marketing value of the LEED label, potential incentives tied to certification, and documented proof for future buyers.
Common LEED Questions
How long does LEED certification take?
It adds 2 to 3 months to overall timeline for documentation, testing, and USGBC review.
Can you retrofit an existing home to LEED?
There's no LEED certification for existing single-family home retrofits, but you can incorporate LEED strategies in remodels.
Is LEED only for large projects?
No. LEED for Homes works for single-family residences of any size.
Do I need an architect for LEED?
Not necessarily. As design-builders, we can handle the entire process including engaging the required LEED Green Rater. We can provide you with custom drawn house plans and be available to help as consultants over the course of the job.
What's the difference between LEED Gold and Platinum?
Gold is 60 to 79 points. Platinum is 80 or more points. Platinum requires exceptional performance across multiple categories and is significantly more difficult to achieve.
Will my utility bills really be lower?
Yes. Our LEED Gold homes typically achieve 30 to 90 percent lower energy costs than conventional homes. Our Danskin Range project maintains itself for $30 per month in utilities.
Can you build LEED homes with straw bale construction?
Absolutely. Our Idaho-first LEED-certified home was straw bale construction. Straw is a readily available renewable resource that can be sourced locally, earns points in multiple LEED categories, and provides exceptional performance.
Does LEED certification help with resale?
Yes. LEED-certified homes typically sell faster and command premium prices due to documented lower operating costs and growing buyer demand for verified green homes.

How much does LEED certification cost?
Certification fees run $3,000 to $8,000 depending on project size and certification level. LEED strategies may add 5 to 10 percent to construction costs, though many LEED credits like proper orientation and efficient design cost nothing extra. Energy savings typically recover additional costs within 5 to 10 years, then continue saving money for the life of the home.
What's the difference between LEED and Energy Star?
Energy Star focuses primarily on energy efficiency and is less expensive to certify. LEED is more comprehensive, covering energy, water, materials, indoor air quality, site sustainability, and innovation. LEED provides third-party verification and is more widely recognized, especially for high-performance homes. We can help you decide which certification makes sense for your project.
Is LEED certification worth it?
If third-party verification, marketing value, and potential incentives matter to you, yes. If you just want the performance without the documentation burden, we can build to LEED standards without formal certification. EarthCraft built Idaho's first LEED-certified single-family home, so we understand both the certified and LEED-equivalent approaches.
