Bullitt Center
The Bullitt Center claims itself as the "greenest commercial building in the world", and with its environmentally friendly design, they're not far from the truth. While most traditional buildings have a lifespan of forty to fifty years, the Bullitt Center, on the other hand, should survive for over 250 years with minimal maintenance and repairs. The Bullitt Foundation began this project by looking for materials that do not contain Red List chemicals for almost two years. As a result, the structure is mostly made of safe materials. Since its inception, the Bullitt Center has been committed to becoming the greenest commercial building by using net-zero water, energy, and carbon.
With over 575 solar panels on the roof, this structure produces much more energy than it uses. Furthermore, their intelligent, high-performance windows allow enough light to filter through during the day, avoiding the need for excessive artificial lighting. Solar panels coupled with smart lighting have greatly reduced their energy use. The Bullitt Center also houses the world's only six-story composting system, where toilet waste is properly processed before being disposed of away. This design lowers trash spilled into the soil and converts it into manure that people may use to cultivate vegetation. The Bullitt Center also has a 'Net Positive Water' goal that it intends to achieve. They also started a rainwater-to-potable water system, which provides clean drinking water sourced from the atmosphere to employees and tenants.
