Since Aurora broke ground on the new medical center in Grafton, it has been a "green" project. In virtually every phase of existence, from construction through furnishing, sustainable, or green elements, have been applied.
Aurora's efforts dovetail nicely with the wishes of the Grafton community. In 2007, the village of Grafton's Finance Committee embraced and endorsed green efforts in their community. The village's new brand became "Quality Life. Naturally." A green framework has been recommended for all Grafton projects including Build Green, Save Green, Power Green, Buy Green, Drive Green and Promote Green.
The Grafton community takes pride in its parks and natural resources and Aurora is proud to assist them in this mission. Aurora will join other LEED certified businesses in the area including US Bank, the village hall, the new public works/community activities facility and the Ozaukee Humane Society being built in nearby Saukville.
- Recycling nearly 99 percent of our construction waste
- Use of construction equipment that operate on low-sulfur fuel and careful monitoring of idle times for construction vehicles
- Extensive campus landscaping with the area's native plantings
- Purchasing regionally-built manufacturing tools which minimizes energy use and pollutants associated with transporting equipment to the job site
- Placement of silt fencing and erosion control measures
- Employing design and construction processes that preserve the wetlands that surround the property
- Using building systems that manage energy use:
- Design that includes extensive use of daylight to reduce power consumption
- Installation of low-flow plumbing fixtures and automated controls to conserve water
- Use of high-efficiency lamps and sensors that automatically turn lights off when a room is unoccupied
- Installation of a white (instead of black) rubber membrane on the roof to reduce air conditioning demands
- AMC Grafton will use 35% less energy than the average U.S. hospital
- Electricity savings alone could power more than 200 Wisconsin homes
- AMC Grafton will save more than 2,500 tons of CO2 per year
How will energy efficiency be accomplished?
- Heat given off by medical equipment and computers is transferred into the heating water system to reduce the amount of natural gas burned in the high efficiency boilers.
- The hot water for showers and hand washing is heated primarily by heat transferred from areas that require cooling such as data (I.T.) closets and medical equipment store rooms
- Daylight sensors turn off lights when adequate daylight is available
- High efficiency steam boilers cycle much more rapidly to match the heating load. The low water volume contained in these boilers allows for quick reactions to changing loads without burning excess natural gas to create standby heat
- Occupancy sensors reduce heating, cooling, and turn off lights when spaces are not occupied
- Reverse osmosis water treatment for boiler make-up reduces chemical usage and energy required to heat reduced amount of water make-up
- Low-flow plumbing fixtures use less cold and hot water. Less energy is used in the heating of hot water and more than one million gallons of water are saved per year
- Carbon dioxide sensors in conference spaces reduce the amount of outside air that is heated and cooled when these rooms are not fully occupied
- Air handling units and air distribution is sized and integrated with the building layout to minimize fan horsepower and energy use
The energy efficient features described above will allow Aurora to recoup its green investment, beginning as early as the first year. Savings will be complete within five years Other Sustainable Features
- AMC Grafton has a white roof that reflects the sunlight, lowering the overall heat of the facility and reducing the need for air conditioning requests
- A number of parking spaces throughout the campus will be designated for hybrid vehicles
- Bike racks around the campus encourage alternative modes of transportation
- Public showers will be available for bike riders
- Public toilets will be dual-flush. Half-flush (liquids) and full-flush (solids) technology can reduce water usage by up to 67% compared with the traditional toilet that typically uses 2.9 gallons in a single flush
