Monsanto Center – Missouri Botanical Garden
This 77,500 square foot building is the Garden’s premier research facility. A total of $250,000 was spent on rezoning HVAC areas, and high efficiency upgrades to boilers and chillers. A 2.5 year payback was accomplished with a 59% reduction of gas use and 41% reduction in electric usage. It was estimated that the increased efficiency resulted in a $1M increase in building value.
