DFW Airport has implemented a parking garage lighting system which serves to visually indicate open parking spaces as they become available. The design helps to minimize unnecessary emissions created by drivers as they search for an open space. Small LED lights at each space in the garage are visible from the ends of aisles, and allow drivers to quickly spot a free space without having to continually circle the garage.
The light sensors also communicate with exterior and aisle signage in real time, letting drivers who enter know which floors have open spots, and preventing further unnecessary driving. As an added benefit, open designated spaces such as accessible and 1-hour parking spaces can also be distinguished by color-coded lights.
This system not only improves the overall efficiency of parking flow and operations, but may serve to provide less opportunity for driving aggravation and accidents within the garage.
All of the waste produced in Minnesota’s Olmsted County that is not able to be reduced, reused, recycled, or composted is taken to the Olmsted Waste-to-Energy Facility. This operation is one of many within the County’s waste management network, and reduces the volume of general waste produced by the area by 90%. Neighboring facilities within the network serve to reduce this amount even further, and include a municipal recycling center, hazardous waste facility, and compost site.
Through the waste-to-energy process, both electricity and steam are created and directed to local buildings within the County’s ‘District Energy System’, including to local medical centers, the Rochester Public Library, and the Mayo Civic & Art Center.
As reported by the County, mixed garbage is sent to a combustion chamber within the facility, and after being fully processed, exits at 10% of its original volume, in the form of ash. Emissions from the process are heavily monitored and filtered in accordance with state and federal air emission standards. The final produced ash is then sent to a local landfill and ‘permanently stored in an environmentally protective holding cell’.

Our lodge has constructed an advanced hybrid energy system, using the combined power of solar and wind sources with an assortment of battery banks and a three-phase inverter system. In total, our solar park contains 180 PV modules, and the system altogether may be monitored remotely.
With this, we have also been able to provide additional modules to a local school, and stimulate the community in a number of other sustainable and innovative ways. To date, our system has allowed for 280 MWh of clean electricity, and provides power to the entire lodge, our dive center’s air compressor, and to our water treatment plant.
Our Carbon Neutral project funds the replacement of high-emission stoves in Oaxaca communities, reducing fuel use by as much as 60% and reducing exposure to harmful indoor air pollution.
Thanks to these cages in our city, recycling has become easier for everyone. If you have plastic bottles, cardboard, or glass at your house, instead of mixing it with organic matter, you take it out to these cages. It is also easier for our city’s waste collection team to take proper care of the recyclable waste.
These are a few samples around our Downtown area of vertical vine growth for shade and privacy purposes. It is an excellent way of implementing urban greenery while providing a practical purpose.
The first group of images displays a line of green shading along several bus stop waiting areas. The next group shows the potential for green shading use in urban parking garages.
Our park uses recycled water for irrigation, in order to prevent a drain on drinking water for the community in times of drought.
To date, Nashville’s B-cycle bicycle sharing initiative offers 310 bicycles through 36 stations around the city, available for public rental. The initiative provides for an efficient and low-impact mode of transportation, a more personal and interactive opportunity to explore Nashville’s sites, and a positive option for health and exercise to the public.
The other included images display some of the public art created to station personal bicycles. These are named ‘Corn and Tomato’, as a project of the Metropolitan Nashville Arts Commission.
Our city has a ‘Cigarette Litter Prevention Program’, and has posted these small canisters in many areas in order to collect used cigarettes. Not only does this help to keep the streets clean, but it also serves to benefit the connected recycling process. While the cigarette butts are small, the organization has seen that their total accumulation is significant, and can be used to recycle into ‘plastic industrial products’.
