Fifth Third Center
201 North Tryon Street Suite 2560
Charlotte, NC 28202
Located at Fifth and North Tryon Street in the heart of Uptown Charlotte, North Carolina, Fifth Third Center has a gross floor area of 756,584 square feet. The exterior façade consists of architectural precast concrete panels, inlaid with granite; the interior architectural features compliment the exterior design.
Fifth Third Center earned LEED Silver in the LEED for Existing Buildings: Operations and Maintenance Rating System in 2010. It has also received the Building Owners and Managers Association (BOMA) 360 designation as well as Duke Energy’s Envision Charlotte Smart Energy Program “Top Energy Saver” award for being one of the top 3 most energy efficient high rises in Charlotte in 2013. The building also won the 2000-2001 International Outstanding Building of the Year (TOBA) award from BOMA.
The installation of Variable Frequency Drives (VFDs), efficient chillers and Air Handling Units (AHU’s) have improved the overall energy consumption of the building. The Central plant has three 500-ton chillers that are designed around a primary/secondary chill water loop system. With this system, excess chill water not being used by the AHU secondary loop can be used to reduce the load on the chillers and still produce the required temperature set point. VFD’s on the secondary loop pumps and constant volume pumps on the primary loop make this possible. Because a fully loaded chiller uses fewer kilowatts per ton than a chiller running at partial load, this arrangement allows the automation system to select chillers in small enough increments to meet the building load without using energy to run additional chillers in a light-loaded condition. The plant is supplemented by a plate and frame heat exchanger during colder temperatures when the outside air temperature allows the production of water cold enough to satisfy the building cooling load.
The HVAC system is supplied by one AHU per floor. These air handling units are equipped with variable speed drives to exactly match the required fan speed to supply multiple-zone variable air volume design using low temperature fan series boxes that includes electric heat on the exterior zones. Each zone has individual thermostats that are tenant adjustable and in addition the exterior zone setpoint range changes depending on the exterior temperature to further capture efficiency. This complex array of equipment is augmented by a Direct Digital Control (DDC) system that allows for optimum start, chill water reset, supply air temperature reset, automatic change-over from winter to summer operating temperature and integrated change over between waterside economizer and mechanical cooling operation.
The building lighting and HVAC system operates on a daily schedule as programmed into the Building Automation System (BAS). In order for our tenants to adjust this daily schedule to meet their needs, the building BAS schedules are accessible via the internet. Each tenant uses a self determined user name and password to log onto the system and then must enter the proper codes to change the schedule. This allows the tenant the ability to access their floor schedule from anywhere and it allows the management company to track extra usage on each floor by tenant.
