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.
Memenuhi Kode Energi
International Energy Conservation Code (IECC) adalah model kode yang dikembangkan oleh International Code Council (ICC) untuk menetapkan persyaratan desain dan konstruksi minimum untuk efisiensi energi pada bangunan. IECC diperbarui setiap tiga tahun untuk menggabungkan praktik dan teknologi konservasi energi terbaru.
IECC, Mengapa Anda Harus Peduli
IECC diadopsi secara luas oleh negara bagian dan kotamadya di seluruh Amerika Serikat. IECC mencakup berbagai aspek penggunaan energi, termasuk selubung bangunan (dinding, atap, dan jendela), sistem pemanas dan pendingin, serta sistem pencahayaan.
IECC mewajibkan kontrol pencahayaan khusus, seperti sensor hunian, untuk meminimalkan pemborosan energi di area yang tidak terisi di berbagai lokasi.
Standar ANSI/ASHRAE/IES 90.1, Standar Energi untuk Tapak dan Bangunan Kecuali Bangunan Hunian Rendah, adalah standar energi yang diakui secara luas yang diterbitkan oleh American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).
ASHRAE 90.1, Mengapa Anda Harus Peduli
ASHRAE 90.1 digunakan sebagai tolok ukur untuk kode energi bangunan di seluruh Amerika Serikat dan berfungsi sebagai jalur kepatuhan dalam IECC yang menguraikan persyaratan minimum untuk kinerja efisiensi energi komponen bangunan komersial termasuk selubung bangunan, sistem HVAC, sistem pemanas air, dan sistem pencahayaan.
Standar ASHRAE 90.1 menentukan kepadatan daya pencahayaan maksimum yang diizinkan dan persyaratan kontrol pencahayaan minimum, termasuk penggunaan sensor hunian di area tertentu.
Title 24, bagian 6 dari Kode Standar Bangunan California, yang secara resmi dikenal sebagai Standar Efisiensi Energi Bangunan untuk Bangunan Hunian dan Non-hunian, Title 24 dikelola oleh California Energy Commission dan diperbarui secara berkala untuk mencerminkan teknologi dan metode efisiensi energi baru.
Title 24, Mengapa Anda Harus Peduli
Title 24 dikenal dengan persyaratannya yang ketat, yang sering kali dianggap lebih ketat daripada yang ditemukan di banyak kode energi lainnya di seluruh Amerika Serikat. Title 24 mewajibkan standar kinerja energi yang ketat untuk semua aspek konstruksi bangunan, yang mencakup pemanas, ventilasi, pengondisian udara (HVAC), pemanas air, dan pencahayaan.
Title 24 mewajibkan pemasangan sensor hunian yang menyesuaikan pencahayaan berdasarkan tingkat hunian ruangan di area tertentu di bangunan komersial untuk memastikan bahwa energi tidak terbuang sia-sia.

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.
