Conserving Water with Restroom Retrofits
The Facilities Management Division is conserving water in Broward County governmental facilities by replacing old faucets with ones that use less water, and in the Governmental Center older toilets are being retrofitted with dual-flush toilets. Replacing one old inefficient toilet with a dual-flush model saves more than 5,400 gallons of water annually and more than $1,000 over the expected lifetime of the toilet. In addition, each new faucet uses less energy since they do not draw on heated water. Educational messaging is also being installed on these new water-saving devices.
Reserved Parking Available for Energy Efficient Vehicles
Reserved parking for electric hybrid or other alternative fuel vehicles is available at the Broward County Governmental Center and Government Center West, and will be available soon at the South, North and West Regional courthouses and the West Regional Library. The incentive encourages County employees and members of the public to consider modes of transportation that have a lower carbon footprint and improve fuel economy. Alternative fuel vehicles also use less oil, are cheaper to maintain, are allowed to use some HOV lanes and can qualify for insurance discounts. The parking lot initiative is sponsored by Facilities Maintenance in consultation with the Energy and Sustainability Program, in response to the Broward County Climate Change Action Plan.
Facilities Maintenance Division Qualifies for Florida Clean Energy Grant
Broward County is one of 22 grantees to receive a Clean Energy Grant from the Florida Energy and Climate Commission. The $237,000 grant awarded to the Facilities Maintenance Division will be used to replace obsolete chillers at the West Regional Courthouse with new energy efficient equipment. The grant is designed to support projects and activities that maximize annual energy savings, reduce long-term costs, and diminish greenhouse gas emissions. In addition to promoting these goals, this initiative will demonstrates the value of energy efficiency as a component of governmental services.
Port Everglades Receives Grant To Reduce Diesel Emission
Port Everglades was awarded a $750,000 grant from the Florida Department of Environmental Protection for diesel emissions reduction through the U.S. Environmental Protection Agency's National Clean Diesel Campaign. Funds will allow the port to retrofit, upgrade or replace diesel engines to reduce emissions. Broward County is also contributing $510,000 to emissions reduction projects at the port. The grant will fund the purchase and installation of diesel emissions reduction equipment for on-road and off-road equipment, replacement of old generators, forklifts, and service vehicles. Other port projects include diesel cargo handling equipment that will be retrofitted with newer emissions reduction technology, and repowering of diesel boats with more efficient, cleaner burning engines.
Broward County Promotes LEED-Construction
Broward County’s very first “green building,” the South Regional Library at 7300 Pines Blvd., opened in February 2007. This facility is LEED (Leadership in Energy and Environmental Design) Certified by the United States Green Building Council.
The South Regional library uses energy, water, materials, and land more efficiently than buildings that are simply built to local code. The project's Silver certification LEED rating for New Construction reflects 35 documented and approved points. Five points were earned under the Energy and Atmosphere category with annual energy savings of 317,800 kWh/year. Other “firsts” at the South Regional Library include bicycle storage, carpooling spaces, on-site storm water retention, light pollution reduction, and landscaping that incorporates only native, drought-tolerant plants.

The Edgar P. Mills Multi-Purpose Center is a new 57,000 square foot facility housing Human Services functions. The Mills Center was designed under LEED principles and is expected to obtain LEED Silver Certification by the end of 2011.
The new Paul DeMaio Library, built in partnership with the City of Dania Beach, is planned for LEED Gold Certification, and will be the County’s first Gold Certified building.
The new Children’s Reading Center and Museum, under construction in partnership with Young At Art Broward and slated to open in 2012, is aspiring to LEED Gold Certification.
Broward County has been a member of the U.S. Green Building Council since 2002, and several employees are LEED-accredited professionals. The County has passed a “Green Building” resolution to make all new building construction LEED-certified. To that end, the Construction Management is working on many sustainable building projects which will LEED-certified. Those projects include the new Broward County Courthouse, the Lauderhill Library and Cultural Center, the Pompano Beach Branch Library and the Ravenswood Bus Maintenance Facility.
County Seeking LEED Existing Building Certifications
The Facilities Maintenance Division is seeking Existing Building (EB) LEED (Leadership in Energy and Environmental Design) certification for the South Regional Courthouse. The LEED EB certification addresses maintenance and cleaning issues, recycling, and system upgrades in five different areas:
- Sustainable Sites,
- Water Efficiency,
- Energy & Atmosphere,
- Materials & Resources,
- and Indoor Environmental Quality.
The Greater Fort Lauderdale Broward County Convention Center is also seeking LEED certification for its existing facility.
New Elections Facility Will be LEED Certified
Construction of the new Supervisor of Elections facility is planned to begin in 2012, with occupancy planned for 2014. The building has been commissioned in accordance with standards of the U.S. Green Building Council.
Energy Efficient Escalators to be Installed at Main Library
A project is underway to replace the escalators in the Main Library and add a new stairway between them. The existing escalators are 25 years old, have had maintenance issues, and are at the end of their lifespan. The new escalators will be more energy efficient and incorporate the latest safety equipment. The stairs encourage fitness by encouraging people to use their own energy to travel between floors.
Consolidated Rental Car Center Reduces Impact to Environment
The Rental Car Center at Fort-Lauderdale International Airport (FLL) opened in 2005, consolidating operations for 10 rental car companies into one location. In addition to the convenience this offers the traveling public, the consolidation eliminated nearly four million miles of shuttle bus trips, conserved three million gallons of fuel, and reduced congestion in the terminal area. A state-of-the-art, self-contained, indoor maintenance and fueling facility reduces potential petroleum-related impacts to the soil and groundwater from leaking fueling facilities and maintenance activities.
Airport Roof Improves Cooling EfficiencyM
Three terminals at the Fort Lauderdale-Hollywood International Airport have been re-roofed to include a white reflective coating to reduce heat and improve the efficiency of air conditioners. This will result in reduced energy consumption, and ultimately reduced greenhouse gas emissions.
Facilities Maintenance Division Seeks Energy Savings
Over the past decade, the Public Works Department’s Facilities Maintenance Division has taken steps to save energy at Broward County facilities, such as:
- installed window film and solar reflective film on more than 10,000 square feet of glass windows at the West Regional Courthouse, keeping 2,000,000 Btu/Hr (200 Btu/Hr/sq. ft.) of heat from the sun from entering the building
- improved insulating values in ceilings and walls in several facilities, lowering air conditioning bills, creating a more comfortable environment for employees and patrons, and extending the life of business equipment and furnishings.
- used NatureScape landscaping around buildings, reducing irrigation and the amount of electrical power needed for mowing, trimming and other building operations – saving an estimated 325,000 kilowatt-hours each year once the project is completed. Building landscapes can be certified for their conservation of water and use of appropriate plants for energy savings: Facilities Maintenance has obtained certification for 37 facilities and seeks to certify 76 facilities by 2013. A total of 88 County building facilities have been NatureScape certified to date.
- replaced or retrofitted more than 4,050 exit signs with energy efficient/energy star qualifying signs. Exit signs operate 24 hours a day, 365 days year. Standard incandescent signs use around 40 watts; their replacements average around 5 watts.
- installed occupancy sensors in ceilings and on walls in offices, conference rooms, and hallways in various facilities in order to limit the unnecessary use of electricity.
- upgraded lighting in more than 4 million square feet of County facilities from standard T12 fluorescent lamps and ballasts to T8 fluorescent lamps and electronic ballasts. Replaced or retrofitted incandescent lamps with compact fluorescent lamps.
- installed air conditioning mechanical system upgrades for more energy efficiency, and variable frequency drives and energy efficient electric motors in chillers, air handlers and elevators in several facilities. More efficient systems are being specified for new construction.
- installed low-flow water fixtures to reduce water consumption at several facilities, including airport terminals.
Airport and Port Install More Efficient Lighting
Fort Lauderdale-Hollywood International Airport is upgrading lighting in all terminals and other facilities to the more energy-efficient fluorescent lamps and ballasts, saving an estimated 20 to 40 percent watts. The Aviation Department is also participating in a pilot program to replace lighting in the parking garages with a more efficient system that will use 35 percent less electricity.
The airport has replaced 320 incandescent taxiway lights with LED lights, which are 85 percent more efficient, have a 100,000 hour life expectancy (versus 8,000 for incandescent), and reduce vehicle miles and person hours expended for maintenance.
Port Everglades Department recently retrofitted lighting at all 11 cruise terminals and three other buildings. Older T-12 bulbs were replaced with new fluorescent ballasts and low-mercury T-8 bulbs which reduce energy and burn longer while providing the same amount of light intensity. Estimates are that more than 2.9 million pounds of carbon dioxide, 3,282 pounds of nitrous dioxide and 17,503 pounds of sulfur dioxide were saved. Mercury and other heavy metals were separated from the recyclable materials in the used bulbs to prevent hazardous materials from entering the landfill.
Port Replaces Older Equipment With More Energy-Efficient Models
Port Everglades Department has invested $4.4 million in upgrades to replace aging equipment with new, more energy-efficient models – a move that’s projected to reduce annual greenhouse gas emissions by 9.8 million pounds of carbon dioxide, 61,101 pounds of sulfur dioxide and 17,091 pounds of nitrous dioxide. Anticipated savings is more than $4.55 million in energy costs over the next decade. Port tenants share in Port Everglades enthusiasm for “green port” initiatives. Crowley Liner Services recently invested $600,000 to convert generator set power from diesel fuel to electric.
Wastewater Treatment Plants Now More Energy Efficient
The Water and Wastewater Services Division has upgraded wastewater treatment plants for increased energy efficiency. Liquids at the North Regional Wastewater Treatment Plant are now run through a series of four treatment modules for aeration and clarification, each with a capacity of 20 million gallons per day. The aeration process, formerly accomplished with four 300 HP mechanical aerators utilizing 900 HP for normal operation, is now accomplished with fine bubble diffusers operating with 500HP blowers. The energy savings is 400HP or 2.628 million kWh per year.
At the North Regional Wastewater Treatment Plant, a 10 million gallon per day reclaimed water plant was added to further polish treated effluent so it can be used for landscape irrigation and process water. The plant also includes filtration and disinfection, which enables it to replace potable drinking water from the Broward County District 2A Water Treatment Plant for these uses, and results in an average energy savings of 4.599 million kWh per year.
A project is underway to expand the Reclaimed Water Treatment Plant at the North Regional Wastewater Treatment Plant, which will reduce demand for potable water in the service area, thereby saving supply, treatment and pumping costs. The North Regional Wastewater Treatment Plant staff is also working on a project to recover bio-fuel from fats, oils and grease at its Septage facility.
Convention Center Goes Green
The 600,000-square foot Greater Fort Lauderdale Broward County Convention Center has replaced lighting and made other facility improvements to save energy and conserve water: • Replaced 112 1,000-watt lighting fixtures in exhibit halls with 400-watt fixtures resulting in the same light levels; using compact florescent lights in as many fixtures as possible
Installed motion-sensing switches on select light fixtures
- Replaced incandescent lights in Exit signs with energy-saving LEDs
- Reset dishwasher rinse temperature at 180 degrees and eliminated use of rinse chemicals.
- Participate in Florida Power & Light’s Sunshine Energy renewable energy purchase
program at Level 2 (30%)
- Installed Johnson Controls Energy Management system
- Coated the curtain wall at the front of building coated to allow light and reflect heat, coated skylights in the atrium, and installed white (reflective) single ply roof membrane
- Installed closed loop system of treatment for cooling towers which reduced water consumption approximately 65% (savings in water/sewage charges and water lost)
- Installed automatic flush valves on all urinals (1.5g)
- Installed 0.5 Tamper Proof Aerators throughout the building.
Water and Wastewater Services Finds Energy Savings
The Enterprise Technology Services section of Water and Wastewater Services initiated its own “Project Green” to begin lowering energy consumption and reduce its carbon footprint. Computer settings at workstations were modified from their factory defaults, resulting in power savings. Modified settings on computer monitors alone achieved 20-30 percent reductions in energy consumption.
Janitorial and Pest Control Contracts are “Green”
A contract for janitorial services at over 80 Broward County facilities requires the use of green cleaning products and procedures, including staff training, whenever possible. It offers better environmental performance and improved worker health and safety, while retaining the same sanitation quality as traditional, more chemical-intensive methods.
A contract for pest control at over 126 Broward County facilities incorporates LEED’s Indoor Integrated Pest Management principles which offers better environmental performance and improved worker health and safety, while retaining the same pest control quality as traditional, more chemical-intensive methods. Use of the contract may also qualify facilities for LEED’s points.
