Engineered Building System
Premium Low-E Specification

Our own super-high performance standard results in an energy efficient home that is kinder to the planet and to your wallet. Think of our Premium Low-E Specification as a blend of what's best about current high-performance building construction standards like R2000, ENERGY STAR & EnviroHome, and add a dash of our own best practices in manufacturing, systems and construction. It will yield a home that beats the R2000 air change target by at least 35% - guaranteed.

The Premium Low-E option will also pay you back significantly by marginalizing energy costs, providing for much better air quality, and reducing environmental impact during construction. Mother Earth will thank you. And so will your wallet.

Our Premium Low-E Specification is designed for those with uncompromising views on the energy and environmental impact that building a new home will have in perpetuity. This eco-conscious specification features the following:

• Optimized design for solar gain
• Insulated concrete form foundation system to maximize basement comfort and usage
• Insulated concrete basement slab system

The Big-Picture Benefits

A Sienna Low-E home comes close to meeting the performance standards of Net Zero Energy Homes - homes that are effectively off-grid, or contributing to the power grid as opposed to drawing from it. Our low energy spec gets approaches the "zero energy" target while respecting the practicalities of your budget.

In return, you get a home with nominal operating costs, excellent air quality, and a cachet that will pay dividends during resale. It's also a great hedge against rising energy costs. The higher the cost of energy rises, the greater your payback will be.
