Residential home

Building End Use:

This project involved the construction of a residential home for clients with a specific vision: a timber frame home incorporating Structurally Insulated Panels (SIPs). Recognizing Tamarack Construction's expertise in SIP construction, the clients specifically sought their services for this project.

SIP Specifications:

Wall: 6.5" total thickness with Neopor Foam core.
Roof: 10.25" total thickness with Neopor Foam core.

Benefits of Using SIPs:

The utilization of SIPs offered several key advantages:

Accelerated Construction: SIPs significantly reduced construction time, streamlining the project timeline and minimizing on-site labor.
Enhanced Energy Efficiency: The high-performance SIPs envelope, featuring Neopor foam, provides exceptional insulation. This translates to significant energy savings for the homeowners, reducing their utility costs and minimizing their environmental impact.

Key Architectural and Engineering Features:

Timber Frame Construction: The home showcases a stunning timber frame design, incorporating over 680 individual timbers.
Structural Innovation: Pre-cast, pre-stressed slabs were utilized to support the garage over the clear-span shop, demonstrating innovative structural engineering.

Building Performance:

Air Tightness: The building achieved an impressive 1.17 ACH50 air leakage rate, further enhancing energy efficiency and improving indoor air quality.
HVAC System:
- Two electric heat pumps for the upper level.
- Gas-fired boiler and in-floor radiant heat for the lower level.
High-Performance Envelope:
- Windows with U-values ranging from 0.26 to 0.30.
- R-49 blown insulation above the garage.
- Hot water heating integrated with the boiler system.
Energy-Efficient Features: All LED lighting and a Heat Recovery Ventilation (HRV) system were incorporated throughout the building.

Sustainable Materials and Finishes:

Interior Finishes: Low-VOC stains were used on interior finishes to minimize indoor air pollution.

Key Improvements:

Enhanced Clarity and Flow: The text now reads more smoothly and concisely.
Stronger Word Choices: More impactful and descriptive verbs and adjectives were used.
Improved Structure: The information is presented in a more logical and organized manner.
Focus on Key Features and Benefits: The unique aspects of the project, such as the timber frame design and the use of pre-cast, pre-stressed slabs, are highlighted.
Emphasis on Sustainability: The focus on energy efficiency, the use of low-VOC materials, and the incorporation of sustainable features is strengthened.
