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.
符合能源法規
《國際節能規範》（IECC）是由國際規範委員會（ICC）制定的示範規範，旨在為建築物的能源效率建立最低設計和施工要求。IECC每三年更新一次，以納入最新的節能實踐和技術。
IECC，您為什麼應該關心
IECC被美國各州和市政當局廣泛採用。IECC涵蓋能源使用的各個方面，包括建築圍護結構（牆壁、屋頂和窗戶）、供暖和冷卻系統以及照明系統。
IECC要求特定的照明控制，例如佔用感應器，以最大限度地減少各個區域未佔用空間中的能源浪費。
ANSI/ASHRAE/IES 標準 90.1，《場地和建築物（低層住宅建築除外）能源標準》，是由美國供暖、製冷和空調工程師學會（ASHRAE）出版的廣泛認可的能源標準。
ASHRAE 90.1，您為什麼應該關心
ASHRAE 90.1被用作美國全國建築能源法規的基準，並作為IECC內的合規途徑，其中概述了商業建築組件（包括建築圍護結構、HVAC系統、熱水系統和照明系統）節能性能的最低要求。
ASHRAE 90.1標準規定了最大允許照明功率密度和最低照明控制要求，包括在特定區域使用佔用感應器。
《加利福尼亞州建築標準規範》第6部分第24章，正式名稱為《住宅和非住宅建築能效標準》，由加利福尼亞能源委員會管理，並定期更新以反映新的節能技術和方法。
Title 24，您為什麼應該關心
Title 24以其嚴格的要求而聞名，通常被認為比美國許多其他能源法規更為嚴格。Title 24對建築施工的所有方面規定了嚴格的能源性能標準，其中包括供暖、通風、空調（HVAC）、熱水和照明。
Title 24要求在商業建築的特定區域安裝佔用感應器，這些感應器根據房間佔用情況調整照明，以確保能源不被浪費。

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.
- 手動控制: Incorporate manual controls that are integrated with the occupancy sensors. This allows for manual override to turn ON/OFF all lighting when necessary.
