Mountain Log Homes of Colorado is proud to once again win the Energy Excellence Award presented by the Summit County Builder's Association & High Country Conservation Center in the 2013 Summit County Parade of Homes. We have a history of winning this award, or coming in a very close 2nd over the past 6 years. Our building practices including ICF (Insulated Concrete Form) Foundations; SIPS Roofs (Structurally Insulated Panels); Low-E windows; 96% Efficient Boiler with In-Floor Radiant Heat; Superior Insulation Package & Caulking Packages; low HERS Index Scores (Home Energy Rating System); and attention to details to avoid Air Infiltration as proven by excellent Blower Door Tests by independent Energy Auditors, makes our client's homes warmer in the winter and cooler in the summer while saving on their Energy Bills.

When you factor in the Thermal Mass of Log Structures in addition to their R-Values, these homes surpass their stick frame counterparts in home energy usage. We build with several species including Pine, Spruce, Fir and Cedar depending on the log supplier, style home the owner is attracted to, and size of the structure and logs desired. Full round log construction is a natural thermal insulator. The logs will retail the sun's heat of the day and slowly release it in the cool evenings. The low density and presence of air spaces in the wood give Western Red Cedar logs a conductivity factor K is 0.74 BTU in/ft2 h F plus an R-Value of 1.35 per inch of diameter...an 18" Cedar log has a natural R-Value of 24.30 with an thermal mass equivalent of R-54. The Canadian National Research Council rates Cedar Log homes as the most energy efficient home construction for all Canadian climates- regardless of home heating fuel type. The DOE (Department of Energy) has Thermal mass factors calculated for all species of wood, and they vary by species. These standard calculations are used in testing or RES-Checks throughout the country and routinely pass all local code s for insulating properties.

How does a HERS Index score affect a home's efficiency? The score indicates how much more efficient a home is than a home built to current building codes. Like Golf, a lower score is better! A home with a score of 54 is rated to be 46% more efficient than a home built to current Building Codes. Since our newest home was completed in June 2013, we don't know yet what a winter gas bill will look like, but expect that his home heating costs on this 4,177 structure will be under $100 per month in Breckenridge winters at 10,000 feet of elevation.

In a recent poll of our owners you can see that this attention to sustainable building practices and Energy Conservation techniques pays off in the form of low heating costs to our owners.
