Mountain Log Homes was awarded the “Energy Excellence Award” by BUILT GREEN COLORADO in 2007 during the Summit County Parade of Homes, competing with 26 homes. This home achieved a ‘5 Stars Plus Rating’ and HERS Index of 59.


According to the Log Homes Council , a typical log home is up to 15% more energy efficient that an identical stick frame structure. Thermal mass of log structures (the ability to absorb, store and slowly release heat over time when temperatures drop) is very high due to the cellular structure, bulk and thickness of the log walls, thus reducing heating and cooling loads. Different species of wood have different R-values. Lodge Pole Pine combined with Thermal Mass factor is 3 per inch giving a 12” diameter log is an R-36 value. Douglas Fir’s combined R-value is a 2, or R-24 for a 12” diameter log. The higher the R-value, the more the wall resists heat loss. Most Stick built framed homes will have average an R-12 value.


Logs are a renewable resource. Your homes logs are the product natural disasters like forest fire and beetle infestation . Harvesting this dead timbers encourages healthy forests and re-growth.We use Locally Harvested “Beatle Kill” Pine for rails and our signature board on board siding.

  • Society of American Foresters Certified Forester on staff to guide all forestry operations

  • Our harvesting process includes sustaining fish and wildlife, perpetuating recreational opportunities, and supporting forest regeneration.

  • We harvest only naturally seasoned, dry-standing trees.

  • Our harvesting techniques include using helicopters to help reduce the need for log skids, and logging during the winter when the ground is frozen and protected by snow and ice.

  • Because the dry-standing trees we harvest are not left to rot and burn, and the natural curing process eliminates the need for kilns, our harvesting process actually results in a negative carbon footprint.

  • Only 10 percent of our harvested logs are good enough to be part of our homes.

  • Recycling. We ship all excess wood to paper mills and cardboard manufacturers.

  • Our "sensitive logging" procedures mean we return every harvested site to a living, natural state.

An Energy Star Home is durable and requires less maintenance in the following ways:

  • A properly drained and insulated foundation avoids moisture intrusion, maintaining a dry and comfortable basement.

  • Outdoor decking and landscaping products made from recycled products look great, last longer and require much less maintenance than traditional decking material.

  • Engineered lumber is made from fast-growing, rapidly renewable trees and provides straighter, stronger, more consistent structural elements.

  • Tough, long-lasting exterior finishes such as brick, stucco, and fiber cement ensure that a home endures for generations and requires less upkeep over the years.

  • Long-lasting and durable roof shingles or materials like slate, cement, or metal reduce waste.

  • Simple items such as downspout extensions on gutters keep water away from foundations and basement walls.

A quarter of Colorado new homes qualify as ‘efficient’Summit Daily News, Friday, October 2, 2009

The Governor’s Energy Office (GEO) announced Monday that ENERGY STAR new homes account ed for more than 26 percent of the new homes built in the first half of 2009 in Colorado. Should 2009’s strong start for ENERGY STAR new homes hold up for the rest of the year, Colorado would see its fifth consecutive year of percentage increases in homes that qualify as ENERGY STAR. Since 2004, the mar ket penetration of ENERGY STAR New Homes has increased from 4.2 percent to 19.4 percent in 2008.

Since July of 2008, at least 11 Sum mit County homes have been built to ENERGY STAR standards, accord ing to High County Conservation Center director Carly Wier. An ENERGY STAR home is typically 20-30 percent more energy efficient than homes built to code and are cer tified throughout the construction process. Better insulation, advanced air sealing strategies, and efficient heating systems and appliances are typically used to achieve better com fort and energy efficiency and the ENERGY STAR certification. ENERGY STAR homes also reduce green­house gas emissions through direct reductions in energy use.

“Summit County builders have been supporting Colorado’s new energy economy by choosing ENERGY STAR certification for their homes,” Wier said. Accord ing to the ENERGY STAR website, there are currently six Summit County builders registered with the ENERGY STAR program, including: Mountain Log Homes of Colorado, Apex Mountain Homes, Greg Hess Construction, Hedges Mountain Homes, J & E Development, and Kodiak Enterprises. J & E Develop ment won the ENERGY STAR Award at the 2009 Parade of Homes.
