Lobby
Discover the energy-saving potential of your lobby. Learn how to meet energy codes and reduce energy waste with our tailored solutions.
Transform Your Lobby into an Energy-Efficient Space
The lobby is often the first point of contact for visitors and employees in a commercial building. It’s a space that needs to be well-lit and welcoming at all times. It’s a bustling area, filled with people coming and going at all hours. The lighting in these areas is typically high-intensity and left on for extended periods, leading to significant energy consumption.
Traditional lighting systems in lobbies are often manually controlled, resulting in lights being left on unnecessarily when the space is unoccupied, leading to high energy waste. Moreover, the diverse activities and varying occupancy levels in lobbies make it challenging to manage lighting efficiently. This not only increases operational costs but also contributes to a larger carbon footprint.
To address these issues, occupancy sensors offer an effective solution. These devices can automatically turn off or dim the lights when the lobby is vacant, significantly reducing energy consumption. Rayzeek’s range of occupancy sensors, including wall and ceiling-mounted options, provide a tailored solution for lobbies, ensuring efficient lighting control without compromising on comfort or safety.
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 Lobby
Designing an energy-efficient lighting control solution for lobby involves strategic placement of occupancy sensors to ensure comprehensive coverage of the space.
In a lobby, the primary areas that need to be covered by occupancy sensors are the entrance, the reception desk, and any seating or waiting areas. Here’s a possible design guide for a lobby:
- Entrance Area: Install a ceiling occupancy sensor near the entrance. This sensor will detect the movement of people entering or exiting the lobby, ensuring the lights are activated when needed. Our ceiling sensors offer Auto ON and Full OFF functionality, providing automatic control of lighting based on occupancy.
- Main Lobby Area: For larger lobbies, additional ceiling sensors may be required to cover the entire space. These sensors should be strategically placed to cover high-traffic areas, such as near the reception desk or waiting areas. The overlapping coverage of multiple sensors ensures there are no blind spots.
- Reception Desk: Place a wall-mounted sensor near the reception desk. This sensor will detect the presence of the receptionist and any visitors at the desk, keeping the lights on in this area during occupied periods.
- Seating/Waiting Areas: Install additional ceiling-mounted sensors in any seating or waiting areas. These sensors will detect when these areas are occupied and adjust the lighting accordingly.
- Manual Control: Install a manual control near the entrance or reception desk. This allows for manual override of the lighting system when necessary.
- Corridors Leading to Other Areas: Corridors leading to elevators, staircases, or other parts of the building should have their own wall or ceiling-mounted sensors. This ensures that lights in these areas are only activated when someone is passing through.
