DUVAL COUNTY UNIFIED COURTHOUSEJacksonville, Florida
The design/build team of Turner Construction with KBJ Architects and TLC Engineering for Architecture was selected in 2008 to provide Duval County with a new secure, state-of-the-art courthouse appropriate to historic downtown Jacksonville.
The seven-story courthouse houses the county’s civil and criminal courts divisions, along with 51 courtrooms, judicial and administrative offices, jury rooms, Clerk of Courts offices, a sally port and holding cells. Visitors pass through security before entering the main lobby. Separate circulation corridors for the public, judiciary, inmates, and staff provide a secure environment. Frequently used public areas such as County Civil, Circuit Civil, Court Files, Probate, Tax Deeds, and Official Records are located on the first floor. Stairs, elevators and escalators provide access to the courtrooms, which are located on floors two through six. Judicial offices, hearing rooms, the Chief Judge’s office and a conference room are on the seventh floor.
Efficiency, cost-effectiveness and flexibility were the engineering goals. The mechanical design includes energy-efficient, variable-volume air handling systems to maintain air quality and comfortable environments in the different types of spaces. The chilled water systems are tied into the downtown

UNIVERSITY OF NORTH FLORIDA STUDENT UNIONJacksonville, Florida
UNF’s Student Union complex gives students a state-of-the-art and sustainable home to call their own. Two three-story buildings house a bookstore, meeting rooms, banquet rooms, restaurants, game rooms, a movie theater, student government offices, senate chambers, a pharmacy, retail, student areas and covered outdoor courtyards. There are two commercial kitchens, one for the Boathouse Restaurant and one for the Union plus a food court with five additional quick serve kitchens. Energy and water efficiency were key goals during the design of the Student Union, which earned LEED Gold certification. The plumbing systems achieved 39% water savings through use of low-flow toilets, waterless urinals and low-flow lavatories. Energy efficient design of the HVAC and lighting systems achieved a 23% reduction below ASHRAE 90.1. The lighting systems were designed with energy efficient fluorescent lighting and occupant sensing lighting controls. The HVAC systems include energy recovery units to supply fresh air, while recovering the energy from the exhausted air. The mechanical systems air handling units use energy recovery units with chilled water and heating water and enthalpy wheels and variable volume terminal boxes serving all zones with heating water reheat and commercial kitchen exhaust and ventilation systems throughout.

Demand-control ventilation was achieved by designing dual duct terminal boxes for all densely occupied spaces with preconditioned outdoor air ducted to one side and conditioned re-circulated air ducted to the other side of the dual duct box. Energy recovery systems precondition and exchange heat from the outdoor air to the exhaust air in the summer and vice versa in the winter.
Sustainable design and construction features of this project include:• Interior lighting fixtures are controlled
by occupancy sensors• Exterior lighting power densities 30%
below ASHRAE 90.1 requirements• No potable water used for irrigation• Reduced potable water use by 49% • Base building HVAC & R systems do
not use CFC-based refrigerants• Carbon dioxide monitors
The 400-kW emergency diesel generator serves as a backup for emergency lighting, fire pump, elevators and fire alarm systems. The classrooms are equipped with state-of-the-art audio-visual systems. TLC also provided design services for the card access system and the closed-circuit television security system.
The building is served by the chilled water/hot water loop from the campus central plant.

UNIVERSITY OF FLORIDA MARTIN H. LEVIN ADVOCACY CENTER
Gainesville, Florida
State-of-the-art facilities at the Levin Law Advocacy Center provide students with hands-on courtroom experience and enhance the school’s distinguished national reputation. The two-story, 18,942 sf stand-alone addition to the college include second floor shell space to accommodate future improvements.
The USGBC LEED-Gold certified building was designed to provide an annual energy cost savings of 21.5% and to reduce annual potable water use by 54.9%. Some of the sustainable design features include:• Variable speed drives on the
mechanical equipment to match the heating and cooling loads with the required delivery air flow.
• Demand control ventilation including monitoring and controlling the CO2 and building pressurization.
• Heat recovery from relief and exhaust air to ventilation air.
• The use of passive reheat to minimize humidity control energy from active reheat.
• Direct digital control systems that monitor, control and adjust the requirements for heating, cooling, ventilation, etc to the delivered capacity precisely.
• Space lighting controls and office passive infrared lighting controls.
• Passive sensor control faucets on plumbing lavatories and flush valves.
• Waterless urinals.
The first floor of the center houses the judges’ chambers/meeting room, office

space for the College’s trial and moot court teams, and two deliberation rooms doubling as 12-seat seminar rooms. The trial and appellate courtroom, also on the first floor, features gallery seating for 108, a 14-person jury box, a judges’ stand capable of seating seven, a witness stand, and space for other courtroom functions such as a clerk/stenographer.
The courtroom is equipped with wireless technology, power and/or data ports and floor boxes, a camera system capable of recording and streaming live feeds both internally and externally, flat-panel displays and playback gear for presentation of evidence. The complex audio/video system is designed for the crucial presentation of evidence. Each of the seven appointed moderators may view the evidence privately, select specific views, and even control by whom and when the evidence is viewed. With multiple robotic cameras and an integrated audio system, the room’s proceedings may be displayed, previewed and stored to be reviewed later. The entire facility’s system controls are also modular, and are designed to be used remotely through the local area network. The courtroom doubles as a classroom, allowing students to experience a real-world courtroom while they are learning.
Separate egress monitored by closed-circuit television provides additional security for the judges.

UNIVERSITY OF NORTH FLORIDA STUDENT WELLNESS CENTER Jacksonville, Florida
The University of North Florida had outgrown the existing fitness center, but the new center has students and staff once again enjoying fitness opportunities and wellness programs.
The Wellness Center includes dedicated group fitness spaces, activity spaces for club sports, free weights, as well as weight machine space, dedicated spaces for indoor sports, passive activity space, retail space, facilities for health assessments, counseling and administration. The third floor features a 1/8 mile running track that circuits the perimeter of the building, providing users with views of the second floor fitness level, atrium and outdoors.
The facility is located in the heart of the UNF campus, in close proximity to the Student Union, earning LEED credits for connectivity while enticing students to fitness classes and wellness programs.
Energy modeling, completed by TLC, shows that the building is 28% more energy efficient than a baseline building, benefiting from tieing into the campus chilled and hot water loops, the use of low lighting power densities and a commitment to continued use of low mercury lamps throughout the facility.
A 37% water use reduction was earned through the use of waterless urinals, low-flow fixtures and motion-activated faucets.

A main feature is a 32 foot tall climbing wall (above), known as the “Osprey Cliff” that extends from the first to third floors. Lighting the climbing wall and atrium space, with a 35’ ceiling, in a way that could be maintained by the University staff provided a challenge. In order to successfully address their concerns, TLC used a BIM REVIT model to demonstrate that access to all fixtures could be achieved with a scissors lift.
