The green revolution in the hospitality industry represents the strategic shift hotels are making toward eco-friendly operations using automation, hotel energy management systems, smart PMS, and hotel operations automation. This approach addresses guest expectations, sustainability mandates, and rising utility costs—all while improving operational performance.

1. Why Hotels Are Embracing Sustainability

Energy and water costs account for a significant fraction of hotel operating expenses. Energy alone can represent up to 25% of operating costs in some hotels. Water usage—especially in water-scarce destinations—can reach 1,500 liters per room per day, far exceeding residential use.

These figures underscore why hotels must shift toward technology-driven resource management to remain competitive and cost-effective.

2. PMS‑Integrated Energy Management: Proven Energy Savings

Washington Hilton Case Study

An independent test of standalone EMS (room-level motion-controlled thermostats) versus networked PMS-integrated EMS found:

  • Standalone EMS: ~27% HVAC energy savings
  • Networked EMS with PMS integration: up to 57% HVAC energy reduction

New Delhi Luxury Hotel (KNX System)

A New Delhi luxury property using a KNX-based automation and PMS-integrated EMS system achieved estimated energy savings of 15–20% through automated HVAC, lighting, and shading control.

Industry-Wide Projections

Wireless energy management systems in hotels can deliver 20–50% energy savings, often achieving ROI within three years.

3. Automation and Smart Systems That Drive Sustainability
