Thermal comfort management device and a method for occupant-tailored thermal comfort and energy efficiency management in hotel rooms integrating regional and international standards.

A system that manages both hotel room comfort and HVAC energy consumption by integrating regional and international thermal standards.

This technology establishes comfort classes for each room by applying both local temperature and humidity comfort standards and international thermal comfort standards. It then analyzes occupant thermal comfort by categorizing temperature and humidity data collected from the rooms based on these classes.

Improving indoor thermal environments typically requires HVAC energy, but excessive consumption leads to increased costs and environmental impact. While countries have their own indoor temperature standards based on climate and demographics, there has been no existing method for hotels with diverse international guests to simultaneously consider regional and international standards to manage both comfort and energy savings.

This technology incorporates regional energy-saving standards to determine energy consumption status by comfort class. It analyzes data only when the room is occupied—specifically when indoor CO2 levels rise above or remain at a threshold during check-in. It also sets target comfort ranges tailored to both domestic and international guest perspectives. The additional or saved energy required to shift between classes is calculated based on the difference in average power consumption of the room's Fan Coil Unit (FCU). This can be applied to hotel and resort room management systems, HVAC operations in accommodations with many international guests, and Building Energy Management Systems (BEMS), allowing for personalized guest comfort while quantitatively managing heating and cooling costs per room.

Key Features:

• A processor that sets thermal comfort classes for hotel rooms based on regional and international thermal comfort standards.
• An analysis step that categorizes temperature and humidity data collected from hotel rooms by thermal comfort class to analyze room comfort.
• Analysis conditions that only evaluate thermal comfort when occupancy conditions are met, such as when indoor CO2 levels rise above or remain at a threshold during check-in.
• A step that determines target comfort ranges based on domestic/international guest perspectives and energy-saving standards, and derives additional or reduced energy consumption resulting from class changes.
