A Sip of Comfort: Building an Energy-Efficient Dream Home

This homeowner's journey began with a spark of curiosity at a state fair. Intrigued by an EPS building, they delved into the world of Structural Insulated Panels (SIPs) and ultimately connected with us through EPS.

The Vision: To build a comfortable, energy-efficient home with a focus on sustainable living.

The Reality: A stunning residence featuring:

  • Superior Insulation: 6-1/2" and 8-1/4" thick SIPs walls and an 8-1/4" thick SIPs roof provide exceptional thermal performance.
  • Spacious Living: A large vaulted living area seamlessly connects to an outdoor deck, creating a bright and airy atmosphere.
  • Energy-Efficient Systems:
    • High-efficiency furnace and air conditioner with zoned systems for optimal comfort.
    • Pella triple-pane windows (U-value 0.18) minimize heat loss and gain.
    • Energy-Star rated appliances and LED lighting further reduce energy consumption.
  • Airtight Construction: A blower door test result of 1.1 demonstrates exceptional air tightness, minimizing drafts and maximizing energy efficiency.

The Outcome: A home with an HERS Index of 42 and an energy use intensity of 84.9 kBtu/ft², showcasing the significant energy savings achieved through the use of SIPs.

This homeowner's commitment to energy efficiency extends beyond the walls:

  • 30-Year Insulated Foundation: Provides long-term protection and energy savings.
  • Comprehensive Air Sealing: Spray foam was used to seal the foundation and truss roof, further enhancing energy efficiency.

This project is a testament to the power of SIPs construction in creating comfortable, sustainable, and energy-efficient homes.
