Greenery in the office is good for putting green in the bank. Plants reduce pollutants, molds, and bacteria in the air, and numerous studies, at both U.S. universities and abroad, indicate that plant life in the office can increase productivity and creative problem solving by 12%-15%, improve recall, focus attention, and inhibit aggression. Properly selected and placed plants can also reduce cooling costs by as much as 20% and keep office humidity in the ideal range. Strategically placed plants also reduce office noise pollution. One study found that plants had a greater impact on employee happiness than windows!
