LEED BD+C: New Construction v2 - LEED 2.2
LEED Platinum 2008
Proximity uses 39.2 percent less energy than a conventional hotel by using ultra-efficient materials and the latest construction technology. The sun’s energy heats hot water with 100 solar panels covering the 4,000 square feet of rooftop. Approximately 700 linear feet of stream was restored by reducing erosion, planting local, adaptable plant species and rebuilding the buffers and banks. Approximately 700 cubic yards of soil were removed to create a floodplain bench, and 376 tons of boulders and 18 logs were used to maintain grade control, dissipate energy and assist in the creation and maintenance of riffles and pools.
The bistro bar is made of salvaged, solid walnut trees. Room service trays are made of bamboo plywood. Newly engineered variable speed hoods in the restaurant use a series of sensors to set the power according to the kitchen's needs and adjusts to a lower level of operation. Geothermal energy is used for the restaurant’s refrigeration instead of a standard water-cooled system. North America's first Regenerative Drive model of the Otis Gen2 elevator reduces net energy usage by capturing the system’s energy, feeding it back into the building’s internal electrical grid.
Other sustainable strategies include:
- Abundant natural lighting, including large energy-efficient “operable” windows (7 feet and 4 inch square windows in guest rooms), connects guests to the outdoors by achieving a direct line of sight to the outdoor environment for more than 97 percent of all regularly occupied spaces.
- Building materials with recycled content include reinforced steel with 90 percent post consumer recycled content, National Gypsum Wallboard 100 percent, asphalt 25 percent and staircase steel 50 percent. Concrete contains 4 percent fly ash.
- About 87 percent of construction waste was recycled, diverting 1,535 tons of debris from landfills.
- Water usage has been reduced by 33 percent by installing high-efficiency Kohler plumbing fixtures.
- Air quality is improved by circulating large amounts of outside air into guestrooms (60 cubic feet per minute) by employing “energy recovery” technology where the outside air is tempered by the air being exhausted.
- Regional vendors and artists were used for materials, reducing transportation and packaging.
- Low-emitting organic compound paints, adhesives, carpets, etc. reduce indoor air contamination.
- Guestroom shelving are made of walnut veneer over a substrate of SkyBlend, a particleboard made from 100 percent post-industrial recycled wood pulp with no added formaldehyde.
- “Education Center” for sustainable practices includes tours of our "green" hotel for guests and outreach programs for students of all ages. Bicycles are available for guests to ride on the nearby greenway.
