GCCI: Lowest EPS® Score & Zero Energy!
G. Christianson Construction is proud to have won two Earth Advantage Builder of the Year awards, which recognize achievements in sustainable & energy efficient construction practices: Lowest EPS® Score & Zero Energy!
As an Earth Advantage builder, G. Christianson Construction entered the first PHIUS certified passive house in Corvallis, Oregon. We completed this passive house in 2016, incorporating a variety of systems & materials to create superior energy efficiency and indoor air quality, as well as being environmentally responsible.
This custom home was built to use 70% less energy than a code built home per the world’s most rigorous Passive House standard. It achieves this by very limited infiltration, thermal bridge free construction techniques, super insulation, and heat recovery ventilation. Its 12” thick walls boast an R-value of 51.8, obtained with 2” of cork insulation over BIBS wall insulation. The 32” thick roof has an R-value of 102.4, while the 17” thick floor has an R-value of 63.9. High efficiency doors and triple paned windows, contribute to its energy efficiency. It also has 8.25 kW solar panels, Energy Star appliances, and natural daylighting to keep its energy bills low. A typical Oregon home of a similar size built to code would have a carbon footprint between 19.1 to 20.6 tons of carbon dioxide per yr.; this home has a carbon footprint of 4.0 tons per year before the solar array, which brings it down to 0 tons of carbon monoxide. The home was computer modeled to make sure it met PHIUS energy requirements. By adding solar panels on the garage this home is Net-Zero energy usage.
Indoor air quality has a huge role in overall health. Where possible, this home has eco-friendly building materials that off-gas fewer harmful chemicals. Its ventilation system not only prevents heat loss, but also reduces airborne contaminates, reducing the chances of health risks like allergies, asthma, and more serious health detriments.
During the construction of this home the landscape was taken into consideration as well. Practices to promote healthy landscapes were implemented. Erosion was minimized by use of straw and minimizing vegetation clearing and deforestation. The landscaping uses many native species and avoids the use of invasive species.
This home’s materials were chosen with the environment in mind. Where possible, locally sourced materials were chosen. All the materials chosen are durable and high quality, to last a lifetime, if not generations.
Water conservation was also addressed in this house. It has metal roofs and gutters plumbed for rain water catchment, Nebia low flow shower heads, and a weather dependent irrigation controller to reduce household water consumption without sacrificing comfort.
In addition to its environmental efficiency, this gorgeous home boasts grey quartz countertops atop white and blue painted shaker cabinetry, dark stainless steel appliances, and a subway tile backsplash in the kitchen. Elegant white walls bathed in natural sunlight accentuate the hickory flooring throughout, with a wood inlay feature to add a nautical flair to the transition from the kitchen to the family room. The sleek bathroom has a seamless tile shower with mosaic accents and modern vanity with clean lines. The reading nook under the stairs in the family room is a cozy spot to curl up with a book. Expansive views greet you through every tilt & swing triple paned window.
Designed with “Not So Big House” principals to be effortlessly comfortable using minimal energy, with exquisite finishes and details, this home is a beautiful and cozy retreat from the bustle of everyday life.
