Those processes have been working, too, as the Chiefs have managed to divert more than half of their total waste to be recycled or composted in recent years.
“[Matt Hawkins’] efforts directly translate into the amount of waste diversion that we are able to set aside,” said Brandon Hamilton, the Chiefs’ Vice President of Stadium Operations. “In the last couple years, we’ve averaged between 50 and 60 percent waste diversion. We average over 800 tons of total waste a year, so over 400 tons of that is going to either recycling or compost.”
Those conservation efforts also extend to the Chiefs’ energy consumption, from simple measures such as swapping out halogen lights for LEDs to making entire systems more efficient.
“We’ve converted whole systems from electric to gas,” said Stadium Systems Manager Chris Bryans. “For example, we have a heated field, and we have an additional boiler that wasn’t really being used. It was a lot of potential heat that was being wasted, so we tied that boiler into the chilled water system that we use to cool the stadium, and in the wintertime, instead of using our electric heaters on the club level, we can use the boiler as a heating system.”
That workaround – which is called “loop heating” – means that the Chiefs don’t need to use 200 electric heaters on game day, saving a tremendous amount of energy and thousands of dollars a month. Additionally, the Chiefs are using automated systems that utilize cool air from the outside – such as when temperatures drop in the middle of the night – to later re-distribute as a cooling measure when it heats up the next day, lowering energy demands when it comes to air conditioning.
