Sustainable design and construction are a cornerstone of Sinclair Construction's business philosophy.

For every home we build, we impose three basic goals:


We view this as the cornerstone of the homes we build—design processes that ensure a home consumes as little energy as possible. Lower energy use not only saves homeowners money, but also has broader societal benefit. Some of our building practices include:

  • The use of 96% two-stage furnaces, with sealed and tested duct systems located in the conditioned space of the home, reducing energy and natural gas usage
  • NEST thermostats that intuitively learn an energy-efficient usage schedule save 19% to 30% on energy consumption. NESTs also connect to wifi and are accessible from smartphones, tablets or laptops
  • Milgard Styline windows, energy efficiency 0.30 U-factor, SunCoat Low-E glass; locally manufactured, results-ing in a lower carbon footprint
  • Clerestory windows that bring light, fresh air, or both into the inner space from the outside
  • Tankless water heaters that heat water on demand save energy by not heating water that is not in use (in most plans)
  • Kohler dual-flush toilets that offer a choice of 1.0 or 1.6 gallons per flush. The high-efficiency 1.0-gallon flush setting reduces water use by more than 30% over the 1.6-gallon mode, which adds up to potential water savings of more than 5,000 gallons per toilet, per year
  • Energy-efficient fluorescent light bulbs
  • Blown-in bib-system insulation provides R-23 and completely fills the wall cavity
  • Air-sealing of the home prevents air loss and water intrusion. Third-party blow-door tested


100 percent of our projects are EPS-rated, meaning you can rest easy knowing that they will be more energy efficient, comfortable and have higher indoor-air quality than code-built homes. Learn more about EPS.

EPS homes are designed, built and performance-tested to provide enhanced comfort, improved air quality and energy savings.

When it comes to being green—look for a home with an EPS.
