Located just south of Morton Arboretum, these buildings are a commanding, but quietly elegant, presence along the East-West corridor. Arboretum Lakes is a beautifully landscaped office campus where buildings of granite and reflective green glass blend with the lakes, trees and a park like environment. The complex is accented with covered walkways, several ponds and a gazebo. A large selection of restaurants and hotels are in the immediate area. Three of the four buildings in the Arboretum Lakes complex have now achieved the ENERGY STAR designation.
Arboretum Lakes I was built in 1986 and consist of 152,634 square feet of beautiful Class A office space in a high image office park. Amenities of this building include an on-site cafeteria with lakeside terrace dining, a health club with aerobic and fitness rooms, private balconies on every floor overlooking Morton Arboretum, and covered parking with direct tunnel access and 24 hour card key access.
Arboretum Lakes began tracking its energy use towards obtaining its ENERGY STAR rating in January of 2006 and first earned the ENERGY STAR designation in December 2006, and again in December, 2007. The rating has continued to improve since that time.

Several years ago Hamilton Partners contracted an energy management professional to consult on the energy concerns at these buildings. The consultant reviews each of the monthly energy bills for accuracy and provides advice on rates and alternate supplier information. Hamilton Partners created a separate company for the purpose of aggregating electricity cost throughout its portfolio in order to obtain bulk discounted pricing. The building utilizes the Engage system for its internal metering needs, electronically tracking use on each of the tenant floors as well as tracking base building mechanical and lighting use and costs.
Hamilton Partners engineering and maintenance staff has begun taking proactive steps to increase efforts to maximize energy efficiency:
? Installation of motion sensors for lighting in dock areas and restrooms.
? Ongoing replacement of T-12 fluorescent bulbs with energy efficient bulbs and ballasts.
? Ongoing replacement of incandescent bulbs with screw in compact fluorescent bulbs.
? Installation of variable frequency/speed drives on its mechanical components, both HVAC and water pumps.
? Installation of condenser coils to increase efficiency of the compressors and lower electrical usage.
? Periodic review and constant tracking of energy use patterns to determine and correct energy inefficiencies.
? Review of lighting schedules and optimization of start up times for HVAC services.
? Daily engineering staff walkthroughs of vacant spaces to ensure only emergency lighting is illuminated and HVAC is appropriately programmed for vacancy.
Other steps Hamilton Partners is taking to reduce its carbon footprint:
? The building has an active recycling program for tenants to recycle paper, glass and plastics. There are recycle bins at each workstation, copy center, printer station for paper recycling as well as centrally located glass and plastics recycling bins. Waste Management supplies recycling services to the building. All of the paper and waste removal products are made with recycled materials.
? Implemented waste reductions through use of the coreless toilet tissue in all its washrooms. Coreless toilet tissue eliminates waste from cardboard cores and is packaged in bulk, rather than in individually wrapped rolls.
? The building staff along with its contract cleaning service instituted green cleaning chemicals rated by the US Green Building Council for all of its regularly scheduled cleaning tasks.
? There are multiple bicycle racks at the complex to promote cycling to work vs. generation of vehicle emissions.
? The building participates in non-chemical goose control through the use of a Border collie service and swans.
