Corridors
Discover the energy-saving potential of corridors with Rayzeek’s occupancy sensor design guide. Uncover the power of automated lighting control in your commercial building’s passageways.
Lighting the Way to Energy Efficiency in Corridors
Corridors, whether in commercial buildings, educational institutions, or healthcare facilities, are high-traffic areas that often remain illuminated throughout the day, leading to significant energy consumption. These spaces typically use fluorescent or LED lighting, which, while energy-efficient, can still contribute to high energy costs when left on unnecessarily.
The challenge lies in the fact that corridors are intermittently occupied, with periods of high foot traffic interspersed with times of vacancy. Traditional manual lighting controls can lead to lights being left on during these vacant periods, resulting in unnecessary energy waste.
By integrating our occupancy sensors into your corridor lighting system, you can ensure that lights are only on when needed, saving energy and reducing costs. Our sensors, including wall and ceiling-mounted options, are designed to comply with US Energy Codes, making them an essential component in meeting energy efficiency requirements for commercial buildings.
エネルギー基準（省エネコード）への適合
国際省エネルギー基準（IECC）は、建築物におけるエネルギー効率の最小設計・施工要件を確立するために、国際基準評価機構（ICC）によって策定されたモデル基準です。IECCは、最新の省エネルギー手法や技術を取り入れるため、3年ごとに改定されています。
IECCに準拠すべき理由
IECCは全米の州や自治体で広く採用されています。IECCは、建築外皮（壁、屋根、窓）、冷暖房システム、照明システムなど、エネルギー利用の多様な側面をカバーしています。
IECCでは、さまざまなエリアの不在空間におけるエネルギーの無駄を最小限に抑えるため、人感センサーなどの特定の照明制御の設置が義務付けられています。
ANSI/ASHRAE/IES Standard 90.1（低層住宅を除く敷地および建築物のためのエネルギー基準）は、米国暖房冷凍空調学会（ASHRAE）が発行している、広く認知されたエネルギー基準です。
ASHRAE 90.1に準拠すべき理由
ASHRAE 90.1は、全米における建築物エネルギー基準のベンチマークとして使用されており、IECC内の適合パスとしても機能しています。この基準は、建築外皮、HVACシステム、給湯システム、照明システムを含む、商業ビル構成要素の省エネルギー性能に関する最小要件を提示しています。
ASHRAE 90.1基準では、許容される最大照明電力密度の規定に加え、特定エリアにおける人感センサーの使用を含む、最小限の照明制御要件を規定しています。
カリフォルニア州建築基準法第24条第6部（正式名称：住宅および非住宅建築物のための建築エネルギー効率基準）は、カリフォルニア州エネルギー委員会（CEC）によって管理され、新しい省エネ技術や手法を反映するために定期的に改定されています。
Title 24に準拠すべき理由
Title 24はその厳格な要件で知られており、全米の他の多くのエネルギー基準よりも厳しいと評価されることがよくあります。Title 24は、暖房、換気、空調（HVAC）、給湯、照明など、建築物施工のあらゆる側面に対して厳しいエネルギー性能基準を義務付けています。
Title 24では、エネルギーの無駄を確実に防ぐため、商業ビルの特定エリアにおいて室内の占有状況に応じて照明を調整する人感センサーの設置が義務付けられています。

Design Guide Key Concepts for Corridors
Designing an energy-efficient lighting control solution for corridors involves strategic placement of occupancy sensors to ensure comprehensive coverage of the space.
In a corridor, the primary goal is to ensure safe and well-lit passage for occupants while minimizing energy waste and all potential access points and the entire length of the corridor are covered by the sensors. Here are some design considerations:
- Sensor Placement: For long corridors, multiple sensors may be required. Ceiling-mounted sensors can be placed at regular intervals along the length of the corridor to ensure comprehensive coverage. Alternatively, wall-mounted sensors can be placed at both ends of the corridor, with their coverage areas overlapping in the middle to avoid any blind spots. Also, consider the height and range of the sensors to ensure they can effectively detect movement across the entire corridor.
- センサータイプ: Depending on the ceiling height and the presence of any potential obstructions, either ceiling-mounted or wall-mounted sensors can be used. Rayzeek’s ceiling sensors offer automatic ON and full OFF functionality, while our wall sensors provide manual ON and full OFF functionality.
- Additional Manual Controls: In addition to occupancy sensors, manual controls can be integrated for instances where manual override is necessary. These controls can be conveniently located near entrances or exits.
- Avoiding False Triggers: Sensors should be placed such that they do not directly face doors leading to other spaces, external light sources and air vents, as this could lead to false triggers when movement is detected in these adjacent spaces.
