Why Denver Homes Are Unique
Located in Climate Zone 5, Denver homes face severe winters. The biggest threat is not just high heating bills, it is heat escaping into the attic and creating snow melt and ice dam risks.
The average residential electricity rate in CO is $0.15/kWh. In colder climates, attic heat loss directly increases utility bills and comfort complaints.
The Hidden Cost of Doing Nothing in CO
By the numbers:
- Annual Heating Degree Days (HDD):5500
- Annual Cooling Degree Days (CDD):800
- High HDD values indicate the dominant seasonal load.
Zone 5 data shows that heating load is the primary driver of avoidable energy waste. Upgrading attic insulation toward R-49 is one of the most direct ways to cut that load.
Cost vs. Value: Is It Worth It?
For a typical 1,000 sq. ft. attic in Denver, a professional blown-in insulation upgrade often costs between $1800 and $2160, depending on labor rates and prep work.
With estimated yearly savings of $480, the project often pays for itself in 3.8 years.
