A green building is one which uses less water, optimises energy efficiency, conserves natural resources, generates less waste, and provides healthier spaces for occupants, as compared to conventional building. A green hospital additionally provides healing environment for faster recovery and reduces Hospital Acquired Infections (HAI).

Introducing green concepts in the healthcare facilities can help address issues like infection, epidemics, handling of bio-medical waste, water efficiency, energy efficiency, reduction in fossil fuel use for commuting, consumer waste and in general conservation of natural resources. Most importantly, these concepts can enhance patients' health, recovery and well-being.

CII established the Indian Green Building Council (IGBC) in 2001 to facilitate Green Building Movement. Since then, Green building movement has gained tremendous momentum and today, India has the second largest registered green buildings in the world.

Benefits of a Green Hospital

• Faster recovery of patients by 15% and reduction in patient stay by 41% due to healing architectural aspects like occupant and patient centric design
• Emphasis on infection control strategies
• Improved Biomedical Waste Management
• Energy savings up to 30-40%, with reference to Energy Consumption building code
• Water savings up to 20-30% with reference to Uniform plumbing code
• Reduction in Operation and Maintenance cost
The concept of Green hospital can enhance patients' health, recovery and well-being. The major focus of the Green Healthcare rating is faster recovery of patients through efficient design, also known as healing architecture. It also emphasises on Hospital Acquired Infection (HAI) and infection control in the building.

Unique design parameters

Green Healthcare system focuses on various design parameters which result in the faster recovery of patients. It emphasises on evidence-based design also known as 'Healing Architecture'. This include availability of daylight in the building, connectivity of the patient area with the outdoor natural environment, having more green spaces & healing gardens in the facility, use of different colours in different wards (colour psychology) which can be an effective mood shifter for the patients etc.

A green hospital also includes aspects such as stress relieving spaces for physical & mental fitness and ergonomics & acoustics for occupant comfort.

Infection control parameters

Various infection control parameters are actively addressed by Green Healthcare facilities. For instance, filtration through MERV 14 and HEPA filters, pressurisation methodologies in critical areas, purification through Germicidal/UV lamps in AHU, Photo Hydro Ionisation at duct level, regular cleaning and antibacterial coating at the high touch surfaces that are prone to infection, 6 feet entryway mat system at the entrance so that the dust and other microbes remain outside the building, etc.
