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.
Atenda aos Códigos de Energia
O International Energy Conservation Code (IECC) é um código modelo desenvolvido pelo International Code Council (ICC) para estabelecer requisitos mínimos de projeto e construção para a eficiência energética em edifícios. O IECC é atualizado a cada três anos para incorporar as mais recentes práticas e tecnologias de conservação de energia.
IECC, Por Que Você Deve Se Importar
O IECC é amplamente adotado por estados e municípios nos Estados Unidos. O IECC abrange vários aspectos do uso de energia, incluindo o envoltório do edifício (paredes, telhados e janelas), sistemas de aquecimento e resfriamento, e sistemas de iluminação.
O IECC exige controles de iluminação específicos, como sensores de presença, para minimizar o desperdício de energia em espaços desocupados em diversas áreas.
A Norma ANSI/ASHRAE/IES 90.1, Padrão de Energia para Locais e Edifícios, Exceto Edifícios Residenciais de Baixa Altura, é uma norma de energia amplamente reconhecida e publicada pela American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).
ASHRAE 90.1, Por Que Você Deve Se Importar
A ASHRAE 90.1 é utilizada como referência para códigos de energia prediais em todos os Estados Unidos e serve como uma via de conformidade dentro do IECC, delineando os requisitos mínimos para o desempenho energeticamente eficiente dos componentes de edifícios comerciais, incluindo envoltórios prediais, sistemas de HVAC, sistemas de aquecimento de água e sistemas de iluminação.
A norma ASHRAE 90.1 especifica as densidades de potência de iluminação máximas permitidas e os requisitos mínimos de controle de iluminação, incluindo o uso de sensores de presença em áreas específicas.
O Title 24, Parte 6 do Código de Padrões de Construção da Califórnia, oficialmente conhecido como Padrões de Eficiência Energética Edilícia para Edifícios Residenciais e Não Residenciais, é administrado pela California Energy Commission e é atualizado periodicamente para refletir novas tecnologias e métodos de eficiência energética.
Title 24, Por Que Você Deve Se Importar
O Title 24 é conhecido por seus requisitos rigorosos, frequentemente considerados mais severos do que os encontrados em muitos outros códigos de energia nos Estados Unidos. O Title 24 exige normas estritas de desempenho energético para todos os aspectos da construção civil, o que inclui aquecimento, ventilação, ar-condicionado (HVAC), aquecimento de água e iluminação.
O Title 24 exige a instalação de sensores de presença que ajustam a iluminação com base na ocupação da sala em áreas específicas de edifícios comerciais para garantir que a energia não seja desperdiçada.

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:
- Posicionamento do sensor: 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.
