The redesign emphasizes spatial hierarchy and visual focal alignment to reflect the institutional strength and refined ethos of a central state-owned enterprise. Key architectural modifications include: Conversion of the original ground-floor office into a reception hall; Removal of two structural beams at the northern entrance, replaced with an expanded canopy; Demolition of the ground-floor ceiling to create a double-height atrium, delivering a dramatic spatial experience that underscores the enterprise’s stature. Lighting Design Philosophy 1. Human-Centric & Health-Oriented Lighting Flicker-free, low-blue-light luminaires prioritize visual comfort and circadian health in office areas. Daylight harvesting technology in window-abundant spaces auto-adjusts artificial lighting based on natural light intensity, enhancing energy efficiency while reducing eye strain. 2. Intelligent & Adaptive Systems IoT-enabled ambient light sensors dynamically regulate brightness (300–750 lux) and color temperature (3000K–5000K) to align with occupancy and daylight conditions. AI-driven scene presets optimize lighting for tasks ranging from collaborative work to executive meetings. 3. Aesthetic & Functional Integration Glare-controlled uniformity (UGR <19) ensures safety and comfort across all activities. Architectural coherence: Luminaire designs harmonize with interior finishes in form, material, and color, amplifying spatial elegance and corporate identity. Technical Innovations Circadian rhythm alignment: Morning-to-evening light transitions support employee well-being and productivity. Energy conservation: Achieved 25–30% energy savings through sensor-based controls and high-efficiency LEDs (120 lm/W).

照明技术指标：
以酒店和办公照明标准为依据，结合项目本身的独特性，设定了相应的照度值。
首层出入口大厅、侧厅、接待区、次入口前厅、VIP电梯厅、电梯厅、走廊平均照度值500-750LUX。二层办公区域平均照度值500LUX。照明色温公共区域：3000-6500K、办公区域4000K。首层基础照明采用软膜天花灯具保证了挑高空间的基本亮度。挑高空间天花与软膜边缘交接处采用灯带勾勒空间轮廓营造氛围。灯具显色显指数（Ra）大于90以上。办公区域的照度均匀值达到0.8以上。

Lighting Standards & Implementation Strategy
The lighting design adheres to hospitality and office illumination benchmarks while incorporating project-specific requirements, with tailored illuminance levels as follows:
1. Illuminance & Color Temperature Criteria
Area Average Illuminance Color Temperature (CCT)
Ground Floor: Entrance Lobby, Side Halls, Reception, Secondary Entrance Foyer, VIP Elevator Lobbies, Elevator Lobbies, Corridors 500–750 lux 3000–6500K (dynamic adjustment)
Second Floor: Office Zones 500 lux 4000K (fixed)
2. Lighting Solutions & Technical Specifications
Ground Floor Base Lighting:
Soft film ceiling luminaires provide uniform ambient illumination for the double-height atrium.
Contour Accentuation: LED strip lighting at the junction of the elevated ceiling and soft film edges delineates spatial geometry while enhancing atmospheric depth.
Office Area Compliance:
Illuminance Uniformity: ≥0.8 across all workspaces to minimize visual fatigue.
Color Rendering Index (CRI): Ra >90 for accurate color representation.
3. Adaptive Lighting Logic
Public Zones (3000–6500K):
Dynamic CCT shifts align with circadian rhythms (e.g., warm 3000K mornings → neutral 4000K midday → cool 6500K afternoon).
Office Zones (Fixed 4000K):
Neutral white light optimizes focus and reduces eye strain during prolonged tasks.

节能措施及效果：
根据不同区域的功能和使用需求，精确计算和设计照度。每个空间区域按照相关标准设计合适的照度，既保证工作所需的明亮度，又避免过度照明造成能源浪费。严格控制照明功率密度，通过优化灯具布局、选择合适的灯具类型和功率，使办公区域的照明功率密度一般控制在 9 - 11W/㎡左右，符合节能标准要求。充分利用自然采光，通过设计大面积的窗户，让自然光尽可能多地进入室内。在白天，根据恒照度系统自动调节人工照明亮度，减少人工照明的使用时间，降低能源消耗的同时，也增强了室内与自然环境的联系。择符合国家安全标准的灯具，具有良好的电气绝缘性能和防触电保护措施，确保使用过程中的电气安全。灯具的外壳材料具有一定的阻燃性能，防止因电气故障等引发火灾。设置完善的应急照明系统，包括疏散照明、安全出口标志灯。
Based on the function and requirements of different areas, accurately calculate and design the illuminance. Each space is designed with suitable illuminance per relevant standards, ensuring adequate brightness for work while preventing energy waste from over - lighting. Strictly control lighting power density. By optimizing luminaire layout, selecting proper types and power, the lighting power density in office areas is generally kept at 9 - 11W/㎡, meeting energy - saving criteria.
Make full use of natural light. Design large - area windows to allow as much natural light as possible indoors. In the daytime, the constant - illuminance system automatically adjusts the brightness of artificial lighting, reducing its usage time, lowering energy consumption, and strengthening the indoor connection with the natural environment.
Choose luminaires that meet national safety standards, with good electrical insulation and anti - electric shock protection for electrical safety. The luminaire casing material should be flame - retardant to prevent fires caused by electrical faults. Set up a complete emergency lighting system, including evacuation lighting and safety exit sign lights.

照明设计创新点：
根据不同办公室功能应用需求，提供情景模式控制、定时控制、自主学习、故障检测等功能设定，系统自主学习用户的节律规律和使用习惯，结合当前季节、时刻、有无人和光照等因素，智能调整神经网络模型参数，为用户提供个性化舒适节律照明体验。
智能照明控制技术，智能照明系统通过DALI网关连接 每一个灯具，实现单灯单控，任意编 组回路（无限制）等功能。实现与企业文化、光环境协调统一，优化能源利用效率。恒照度（日光采集）系统，充分利用自然光，实时的根据光 线强弱自动改变亮度。大大提高了灯具寿命，且节约能源。兼顾了毫米波人体感应器雷达，可根据需求选择人来开灯，人走关灯， 也可以根据时间段启动此功能。
In response to the functional requirements of different offices, functions like scenario - mode control, timed control, autonomous learning, and fault detection are set up. The system learns users' rhythm patterns and habits, and factors in season, time, occupancy, and light levels. It then smartly adjusts neural network model parameters to offer users a personalized, comfortable lighting experience.

Smart lighting control technology sees the system linked to each luminaire via a DALI gateway, enabling single - lamp control and unlimited grouping. This coordination with corporate culture and the light environment optimizes energy efficiency. The constant - illuminance (daylight harvesting) system uses natural light fully, auto - adjusting brightness based on light intensity, which extends fixture life and saves energy. Additionally, the system integrates a millimeter - wave human - body sensor radar, allowing options like occupancy - based or time - based lighting control.
