Project Overview
TC Legend Homes Beacon Hill Positive Energy
End Use: Residential Single Family Positive Energy Home
Why SIPs?: TC Legend Homes was selected as the builder for this project. TCL coordinated all aspects of the project from design through construction and chose the best energy-efficient envelope to fit the homeowner's budget - much due in part to Premier SIPs!
Benefits of SIPs:
- Install time is days, not weeks as with standard framing
- Reduction of outside labor
- Costs are less expansive overall for the options available on a net-zero/positive energy project
- Energy savings are significant with an airtight structure and strategic HVAC/Solar System.
Innovative Design Elements: The entire project was engineered to both fit the homeowner's budget in the heart of Seattle and be as energy efficient as possible. This required planning from the start to ensure all systems were complimented and optimized. While there was considerable upfront planning to achieve high levels of energy efficiency (especially in the expensive Seattle region) on a budget, the construction process was optimized and all systems were pre-planned / installed quickly for reduced construction time.
