From Lighting to Comprehensive Space Energy Management | Signify’s Interact Office Flex System Receives a Major Upgrade

Signify’s Interact Office Flex smart interconnected system goes beyond lighting to deliver an intelligent, whole‑space energy management solution

· The new system supports both on‑premises deployment and cloud‑based operation, helping to reduce operating costs for daylighting, HVAC, and other building systems

· Leveraging AI technology and rich data insights, the system uses sensor‑equipped luminaires to collect occupancy data, dynamically adjusting and optimizing HVAC control and daylight harvesting efficiency

· Highly scalable, the system is compatible with 60% of China’s existing commercial buildings. According to Signify’s proprietary algorithms, this whole‑space energy management solution can cut overall indoor energy consumption by approximately 10%

Signify recently announced a strategic upgrade to its Interact Office Flex system, enabling dynamic adjustment and optimization of HVAC control and daylight harvesting through the sensor network embedded in the lighting system. By unlocking the full potential of smart, interconnected lighting, Signify is advancing from traditional lighting efficiency toward comprehensive, intelligent whole‑space energy management.

The new applications and services operate seamlessly across on‑premises infrastructure and cloud platforms, leveraging artificial intelligence to optimize operating costs for lighting, HVAC (heating, ventilation, and air conditioning), and other building systems. In typical office settings, the system directly reads real‑time environmental data from sensor‑equipped luminaires, dynamically adjusting and fine‑tuning HVAC operations and curtain motor controls. With high adaptability, the system covers 60% of China’s existing commercial buildings; according to Signify’s patented algorithms, its whole‑space energy management capabilities can reduce overall indoor energy consumption by about 10%.

Connected lighting has long been a key enabler of modern office productivity. By applying advanced AI algorithms and extending the control architecture beyond lighting to encompass additional building systems, Signify empowers facility managers to transform every luminaire into an intelligent node, achieving holistic regulation of a building’s thermal load and energy use.

Guan Yuxiang, General Manager of Signify’s Greater China Product Center, stated:

“

Today, customers face challenges such as fragmented, complex building management systems and mounting operational complexity. By expanding Interact Office Flex into the realm of intelligent whole‑space energy management, we’re consolidating these disparate systems into a unified, synergistic whole. This upgrade not only simplifies day-to-day operations but also delivers deeper, more sustainable energy efficiency gains across the entire physical space.”

Core Capability Enhancements of Interact Office Flex

The upgraded Interact Office Flex introduces several core capabilities, enabling smarter, data‑driven building management:

Lighting as a Sensor Network:

Smart luminaires equipped with built-in sensors create a high‑resolution data collection network throughout the building, providing critical insights for optimizing spatial energy efficiency. Combined with automated curtain‑control algorithms, the system maximizes natural daylight while selectively blocking solar heat gain, achieving dual optimization of occupant comfort and energy efficiency.

Focused on Spatial Environmental Management:

HVAC and daylight‑harvesting functions are integrated into a unified control panel. Based on real‑time indoor occupancy and external environmental parameters, the system dynamically balances natural light and artificial illumination, while finely tuning HVAC zones and curtain positions to maximize the efficient use of renewable energy sources.

Proactive, Forward‑Looking Operations:

A spatiotemporal large language model is introduced to aggregate and analyze diverse data types—covering indoor and outdoor conditions, environmental parameters, and user behavior. Through a single, comprehensive dashboard, the system provides facility managers with real‑time operational visibility, significantly streamlining routine maintenance and offering data‑driven support for proactive upkeep.

As cities and enterprises accelerate toward net-zero goals, incremental energy‑efficiency improvements alone are no longer sufficient to meet deeper development needs. Signify seamlessly integrates AI‑driven HVAC control and daylight harvesting into a unified digital infrastructure, harnessing smart technologies to unlock the carbon‑reduction potential of everyday office environments. By continuously expanding the value proposition of light as a carrier of spatial intelligence, Signify delivers scalable, rapidly deployable solutions that support sustainable urban development.
