Healing the Planet, Healing Ourselves: Climate-Conscious Healthcare (Part 3)

In previous parts, we explored how hospitals and clinics can reduce their carbon footprint through energy, transport, and digital health. In this third installment, we turn to infrastructure—the buildings, systems, and spaces that shape healthcare delivery.

Why Hospital's Infrastructure Matters

Hospitals are among the most energy-intensive buildings in any city. They run 24/7, require strict temperature control, and house complex equipment. But they also offer immense potential for climate resilience and sustainability.
Designing Climate-Resilient Hospitals

India’s diverse climate—from coastal humidity to Himalayan cold—demands region-specific design. A one-size-fits-all approach leads to waste and inefficiency.

Case Example: Shanti Seva Hospital in Bhubaneswar faced frequent flooding during monsoons. In 2024, they rebuilt their outpatient wing on stilts, added permeable paving, and installed rainwater harvesting tanks. The result? Zero flood-related closures and a 40% reduction in water bills.

Actionable Tip: Hospitals in flood-prone areas should elevate critical zones, use water-absorbing landscaping, and install backup solar power for emergencies.

Passive Cooling and Natural Light

Instead of relying solely on air conditioning, hospitals can use passive cooling techniques—like cross-ventilation, reflective roofs, and shaded courtyards.

Case Example: A maternity hospital in Udaipur redesigned its waiting area with jaali screens, high ceilings, and north-facing windows. The space stayed cool even in peak summer, reducing AC usage by 50%.

Actionable Tip: Architects should prioritize natural light and airflow in new builds. Retrofitting older buildings with skylights and ventilators can also help.

Smart Energy Systems

Hospitals can install energy dashboards to monitor real-time usage and identify waste. These systems help staff make informed decisions.

Case Example: At Aarogya Multispecialty in Nagpur, the facilities team noticed unusually high energy use in the pathology lab. Investigation revealed that centrifuges were left running overnight. A simple scheduling fix saved ₹80,000 annually.

Actionable Tip: Use smart meters and dashboards to track usage. Train staff to interpret data and act on it.

Water Conservation in Healthcare

Hospitals use vast amounts of water—for cleaning, sterilization, and patient care. But much of it can be reused or conserved.

Case Example: A dialysis center in Surat installed a greywater recycling system. Water used for handwashing and cleaning was filtered and reused for gardening. Over a year, they saved 1.5 lakh liters.

Actionable Tip: Install low-flow fixtures, dual-flush toilets, and water recycling systems. Monitor usage and set reduction targets.

Sustainable Materials and Interiors

From flooring to furniture, hospitals can choose low-emission, recyclable materials that reduce indoor pollution and environmental impact.

Case Example: A pediatric clinic in Bengaluru replaced vinyl flooring with bamboo composite tiles—durable, non-toxic, and locally sourced. Parents reported fewer allergy complaints, and the clinic earned a green building certification.

Actionable Tip: Avoid PVC, formaldehyde-based adhesives, and synthetic carpets. Choose natural, locally sourced materials wherever possible.

Leadership and Long-Term Planning

Sustainable infrastructure requires vision. Leaders must integrate climate goals into master plans, budgets, and vendor selection.

Case Example: A hospital chain in Kerala created a “Green Infrastructure Roadmap” for all new projects. It included solar feasibility, rainwater harvesting, and LEED certification targets. Within two years, three new facilities met green building standards.

Actionable Tip: Include sustainability metrics in RFPs and vendor contracts. Appoint a green officer or committee to oversee implementation.
