UniQue Site Design ::
The SeQuential biofuel station is a demonstration in realistic, feasible, and sustainable technologies:: examples of real world solutions that reduce energy usage and impacts on local water quality.

Solar Power::
Photovoltaic cells installed by the Easly Brothers convert light from the sun into electric current that powers pumps, lights and appliances on site. The canopy over the fuel pumps is made up of 16,128 individual photovoltaic cells on 224 panels. The solar panels generate 33 kilowatts of electrical power, enough to provide 30% to 50% of the power that the station requires.

Passive Solar Design::
Large south-facing windows provide daylight and heat during cool months. The large interior space has a centrally-located "thermal wall" designed to absorb heat from sunlight, and radiate it throughout the building. The design also maximizes the building's ability to cool and heat without active heating or cooling systems. The design increases the building's overall operating efficiency.

Living Roof::
The plants and soil on the living roof absorb rainwater like a sponge, releasing it slowly to the bioswale on the ground. The living roof contains over 4500 individual plants in 5 inches of soil. The layer of plants and soil reflects sunshine and acts as insulation, keeping the interior building space cooler during the summer months.

Bioswales::
The station is located on a former brownfield that had been a gas station years ago. SeQuential's goal was to remediate the site, leaving it clean for future generations. With the Willamette River only a few thousand feet away, SeQuential paid serious attention to designs that considered soil and water quality. Installing bioswales was a key solution. Rainwater carries pollutants and sediments into the bioswale from roadways and parking areas. The bioswale catches the rainwater, slows its flow, and holds the water on site. The plants in the bioswale filter toxic pollutants and sediments out of the rain water. Microorganisms in the soil then break down toxic pollutants.
