Revolutionize Your Open Office Lighting with Smart Occupancy Sensors
Open offices, characterized by their large areas and cubicle partitions, are a common sight in many modern workplaces. These spaces are typically bustling with activity, filled with employees working, collaborating, and moving around. The expansive area requires ample illumination, often provided by high-intensity light fixtures. These lights, left on throughout the workday, consume a substantial amount of energy. Moreover, even when the office is vacant, during off-hours or lunch breaks, the lights often remain on, leading to unnecessary energy consumption.
The high energy consumption of lighting in open offices is a concern for both environmental and economic reasons. With the increasing emphasis on energy efficiency and sustainability, businesses are seeking ways to reduce their energy footprint. Moreover, energy costs can account for a significant portion of a company’s operating expenses, making energy-saving measures a smart financial decision as well.
To address this, the integration of occupancy sensors in open offices presents a compelling solution. Occupancy sensors can automatically control lighting based on the presence of individuals in the space, significantly reducing unnecessary energy consumption. When the office is vacant, the sensors can automatically switch off or dim the lights, thereby conserving energy. With our sensors seamlessly integrated into your open office layout, you can transform your open office into an energy-efficient workspace that meets the stringent requirements of US Energy Codes.
الامتثال للوائح القياسية للطاقة
قانون حفظ الطاقة الدولي (IECC) هو قانون نموذجي تم تطويره بواسطة مجلس القوانين الدولي (ICC) لوضع الحد الأدنى من متطلبات التصميم والبناء لكفاءة الطاقة في المباني. ويتم تحديث IECC كل ثلاث سنوات لإدماج أحدث الممارسات والتقنيات في مجال حفظ الطاقة.
قانون IECC: لماذا ينبغي أن تهتم به؟
يُطبق قانون IECC على نطاق واسع من قبل الولايات والبلديات في جميع أنحاء الولايات المتحدة. ويغطي IECC جوانب مختلفة من استخدام الطاقة، بما في ذلك غلاف المبنى (الجدران والأسقف والنوافذ)، وأنظمة التدفئة والتبريد، وأنظمة الإضاءة.
ينص قانون IECC على عناصر تحكم محددة في الإضاءة، مثل أجهزة استشعار الإشغال، للحد من هدر الطاقة في المساحات غير المشغولة في مختلف المناطق.
تُعد معايير ANSI/ASHRAE/IES Standard 90.1، الخاصة بطاقة المواقع والمباني باستثناء المباني السكنية منخفضة الارتفاع، معيارًا معترفًا به على نطاق واسع للطاقة، صادرًا عن الجمعية الأمريكية لمهندسي التدفئة والتبريد وتكييف الهواء (ASHRAE).
معيار ASHRAE 90.1: لماذا ينبغي أن تهتم به؟
يُستخدم معيار ASHRAE 90.1 كمرجع للوائح طاقة المباني في جميع أنحاء الولايات المتحدة، ويُعد مسارًا للامتثال ضمن قانون IECC، حيث يحدد الحد الأدنى من المتطلبات للأداء الموفر للطاقة لمكونات المباني التجارية، بما في ذلك أغلفة المباني، وأنظمة التدفئة والتهوية وتكييف الهواء (HVAC)، وأنظمة تسخين المياه، وأنظمة الإضاءة.
يحدد معيار ASHRAE 90.1 الحد الأقصى لكثافة قدرة الإضاءة المسموح بها والحد الأدنى لمتطلبات التحكم في الإضاءة، بما في ذلك استخدام أجهزة استشعار الإشغال في مناطق محددة.
العنوان 24، الجزء 6 من قانون معايير البناء في كاليفورنيا، المعروف رسميًا باسم معايير كفاءة طاقة المباني للمباني السكنية غير السكنية، تُديره لجنة الطاقة في كاليفورنيا ويتم تحديثه بشكل دوري ليعكس تقنيات وطرق كفاءة الطاقة الجديدة.
العنوان 24 (Title 24): لماذا ينبغي أن تهتم به؟
يشتهر العنوان 24 بمتطلباته الصارمة، والتي تُعتبر في كثير من الأحيان أكثر صرامة من تلك الموجودة في العديد من لوائح الطاقة الأخرى عبر الولايات المتحدة. وينص العنوان 24 على معايير صارمة لأداء الطاقة لكافة جوانب تشييد المباني، والتي تشمل التدفئة والتهوية وتكييف الهواء (HVAC)، وتسخين المياه، والإضاءة.
يتطلب العنوان 24 تركيب أجهزة استشعار الإشغال التي تضبط الإضاءة بناءً على إشغال الغرفة في مناطق محددة من المباني التجارية لضمان عدم هدر الطاقة.

Design Guide Key Concepts for Open Offices
Designing an energy-efficient lighting control solution for open offices involves strategic placement of occupancy sensors to ensure comprehensive coverage of the space.
In an open office setting, the primary areas to consider for sensor placement are the main walkways and areas with high foot traffic. These areas are crucial for sensor placement as they are the main areas of human traffic:
- Cover Main Walkways: The main walkways in an open office are the areas with the highest foot traffic. Therefore, these should be the primary focus when placing sensors. Ceiling-mounted sensors are ideal for these areas as they provide a wide coverage area and are strategically placed to cover the entire length.
- Overlap Coverage on Walkways: To avoid blind spots, ensure that the coverage patterns of the sensors overlap along the walkways. This ensures continuous detection as people move through the space, preventing any gaps in sensor coverage.
- Use a Long Timeout: Given the size and activity level in open offices, use a longer timeout setting (15 or 20 minutes) on the sensors. This prevents the lights from turning off too soon when there’s no movement detected for a brief period.
- Consider Wall-Mounted Sensors: If the cubicle walls are short, consider using wall-mounted sensors in addition to ceiling-mounted ones. These can provide additional coverage and ensure that all areas of the office are monitored.
- Avoid Air Vents: Don’t place sensors near air vents. The vibration and airflow can reduce the effectiveness of the sensors. PIR sensors should not be within 4ft of an air vent, and ultrasonic sensors should not be within 6ft of an air vent.
- Manual Control: Incorporate manual controls that are integrated with the occupancy sensors. This allows for manual override to turn ON/OFF all lighting when necessary.
