Applying Ecological Design: Indoor Plants

People in industrialized countries can spend up 90 percent of their time indoors, increasing their exposure to indoor air pollution. Indoor plants can dramatically improve human productivity and health, and effectively eliminate a number of volatile organic compounds (VOCs) that come from adhesives, furnishings, clothing, and solvents. Indoor plant systems range from common house plants to more complex indoor-outdoor vertical walls.

Humans have a biophilic response to plants. Research has explored how exposure to plants, or even images of plants, indoors and outdoors can improve productivity and create a sense of well-being.

Indoor plant benefits include:

  • Improved indoor air quality: With the right plants, indoor plants can reduce up to 87 percent of common household air pollutants.
  • Improved health: Up to ten percent reduction of rates of asthma, headaches, and respiratory problems.
  • Increased human productivity: Productivity rates can increased by 20 percent in environments with superior air quality.
  • Reduced energy usage: Energy usage can be reduced by 15 percent because less air circulation is required with indoor plants.
