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.
Cumplimiento de los códigos energéticos
El Código Internacional de Conservación de Energía (IECC) es un código modelo desarrollado por el Consejo Internacional de Códigos (ICC) para establecer los requisitos mínimos de diseño y construcción en materia de eficiencia energética en edificios. El IECC se actualiza cada tres años para incorporar las últimas prácticas y tecnologías en conservación de energía.
Por qué debería interesarle el IECC
El IECC ha sido adoptado ampliamente por estados y municipios de todo Estados Unidos. El IECC abarca diversos aspectos del uso de la energía, como la envolvente del edificio (paredes, cubiertas y ventanas), los sistemas de calefacción y climatización, y los sistemas de iluminación.
El IECC exige controles de iluminación específicos, como sensores de presencia, para minimizar el desperdicio de energía en espacios desocupados en diversas áreas.
La norma ANSI/ASHRAE/IES 90.1, Norma energética para sitios y edificios, excepto edificios residenciales de baja altura, es una norma energética ampliamente reconocida y publicada por la Sociedad Americana de Ingenieros de Calefacción, Refrigeración y Aire Acondicionado (ASHRAE).
Por qué debería interesarle la norma ASHRAE 90.1
La norma ASHRAE 90.1 se utiliza como referencia para los códigos energéticos de edificación en todo Estados Unidos y sirve como vía de cumplimiento dentro del IECC, definiendo los requisitos mínimos para el rendimiento de eficiencia energética de los componentes de los edificios comerciales, incluidos los cerramientos de los edificios, los sistemas HVAC, los sistemas de calentamiento de agua y los sistemas de iluminación.
La norma ASHRAE 90.1 especifica las densidades máximas de potencia de iluminación permitidas y los requisitos mínimos de control de iluminación, incluida la instalación de sensores de presencia en áreas específicas.
El Título 24, parte 6 del Código de Normas de Edificación de California, conocido oficialmente como las Normas de Eficiencia Energética en Edificios para Edificios Residenciales y No Residenciales (Título 24), es administrado por la Comisión de Energía de California y se actualiza periódicamente para reflejar las nuevas tecnologías y métodos de eficiencia energética.
Por qué debería interesarle el Título 24
El Título 24 es conocido por sus exigentes requisitos, a menudo considerados más estrictos que los de muchos otros códigos energéticos de Estados Unidos. El Título 24 exige normas estrictas de rendimiento energético para todos los aspectos de la construcción de edificios, como la calefacción, la ventilación, el aire acondicionado (HVAC), el calentamiento de agua y la iluminación.
El Título 24 requiere la instalación de sensores de presencia que regulen la iluminación en función de la ocupación de las salas en áreas específicas de edificios comerciales para garantizar que no se desperdicie energía.

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.
- Tipo de sensor: 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.
