The Healthy Facilities Institute (HFI) strives to provide authoritative information for creating and maintaining clean, healthy indoor environments. Since buildings are ecosystems, HFI works to address the many interrelated aspects of built environments - such as air, water, energy, materials and resources, green cleaning, indoor environmental quality, waste management, people and more - as an integrated or holistic system. Inasmuch as 'Clean' is a metaphor for healthy indoor spaces, HFI also emphasizes prevention and removal of pollutants or contaminants to help ensure optimum conditions for living, learning and working.
