Schneider KNX Dimming Modules: Intelligent Lighting Case Study for Commercial Complexes

Case Detail

Project Background

East China International Financial Center (420,000 m², including office buildings, shopping malls, and hotels) faced three major challenges with its lighting system:

Complex multi-format scenario requirements that traditional controls could not meet
Lighting energy consumption accounting for 28% of total building energy, creating significant energy-saving pressure
Poor system compatibility and low operational efficiency

The project team partnered with Schneider Electric to build an integrated intelligent lighting control system, centered on the KNX intelligent lighting system and supported by dimming modules such as MTN649-7091 and MTN669-591.

Core Solution

1. Product Selection & Application

Product Model	Core Function	Application Area
MTN649-7091	4-channel 1-10V dimming, constant illuminance control	Office areas of office buildings, shopping mall corridors
MTN669-591	High-power dimming, millisecond-level response	Shopping mall atriums, hotel ballrooms
MTN6720-0004	DALI single-lamp precision control	Hotel guest rooms, high-end brand stores
MTN6702-0008	8-channel extended dimming module	Public areas of office buildings, hotel corridors
MTN6710-1102	Logic linkage main module	Fire emergency, cross-area scenarios
MTN6710-0105	Emergency lighting dedicated dimming	Emergency circuits in all areas

2. Multi-Format Implementation

Office Buildings: MTN649-7091 enabled "lights on when people arrive, off when they leave", reducing office area energy consumption by 35%; meeting room scene switching response time <0.5 seconds.
Shopping Mall: MTN6720-0004 enabled single-lamp precision control in stores; atrium light shows increased foot traffic by 12%; corridor energy consumption reduced by 40%.
Hotel: Guest room "welcome mode" triggered by card insertion; 8 ballroom scenarios switchable with one tap; guest satisfaction reached 96%.

3. System Integration

Seamless integration with BAS, fire safety, and energy management platforms for centralized visual control
Fault response time reduced from 4 hours to 30 minutes, improving operational efficiency by 87.5%

Implementation Results

Experience Upgrade: Office comfort increased by 40%, hotel guest satisfaction reached 96%
Significant Energy Savings: Total lighting energy consumption reduced by 32%, saving over ¥2.8 million in annual electricity costs
Efficient Operations: Maintenance staff reduced by 30%, troubleshooting time shortened by 80%
Compliance & Sustainability: Met fire safety codes, helping the project achieve LEED Gold certification

Conclusion

Schneider's full range of dimming modules, leveraging the open KNX protocol, precisely meet the multi-format needs of large commercial complexes, delivering triple value: "personalized experience, refined energy management, and intelligent operations". This provides a replicable paradigm for smart building construction.
