Guest Room Management
System (GRMS) Design
GRMS design for 4-star and 5-star hotels — room automation, energy management, DND/MUR signalling, welcome scenes, BMS integration and KNX/BACnet protocol design for superior guest experience and energy efficiency.
What We Offer
A Guest Room Management System (GRMS) is the intelligence platform that automates and personalises every aspect of the hotel guest experience — from welcome lighting scenes on card insertion to energy-saving setback when the room is unoccupied. ASDV Consultant provides professional GRMS design services for 4-star and 5-star hotels, resorts and serviced apartments.
Our GRMS designs integrate room controller technology (KNX, BACnet, proprietary) with HVAC control (FCU, fan speed, thermostat), lighting control (dimming, scene setting), window blind/curtain control, DND/MUR door signs, room status display, mini-bar monitoring, safe monitoring and integration with the Property Management System (PMS) and BMS.
GRMS is one of the most effective hotel energy management tools — reducing HVAC and lighting energy in unoccupied rooms by 30–50% through occupancy-based setback. We design GRMS systems that balance guest comfort (rapid room recovery after key insertion) with energy performance, supporting hotel sustainability certifications (LEED, Green Key, EarthCheck).

Frequently Asked Questions
A GRMS is a building automation system specifically designed for hotel guest rooms. It integrates HVAC, lighting, blinds, door status, DND/MUR signalling, mini-bar and room status monitoring into a single room controller connected to a central management server. GRMS enables energy savings by automatically reducing HVAC and lighting when rooms are unoccupied, while providing guests with intuitive control of their room environment.
Independent studies show GRMS reduces HVAC energy consumption in guest rooms by 20–45% compared to non-automated rooms, primarily through occupancy-based setback (raising cooling setpoint by 3–4°C when unoccupied) and lighting auto-off. For a 300-room hotel in India's climate, this typically represents annual energy savings of ₹15–25 lakhs in electricity costs — providing payback periods of 3–5 years on the GRMS investment.
The Property Management System (PMS) — such as Opera, Fidelio or HotSOS — manages room check-in/checkout, housekeeping status and guest preferences. GRMS integrates with the PMS to: receive checkout commands (switching room to setback mode immediately after guest checkout), receive check-in advance notice (pre-conditioning the room to set temperature before guest arrival), and send room status updates (DND, MUR, minibar, room temperature) to housekeeping and front desk.
