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.
Voldoe aan de energiecodes
De International Energy Conservation Code (IECC) is een modelcode die is ontwikkeld door de International Code Council (ICC) om minimale ontwerp- en bouwvereisten voor energie-efficiëntie in gebouwen vast te leggen. De IECC wordt elke drie jaar bijgewerkt om de nieuwste praktijken en technologieën op het gebied van energiebesparing op te nemen.
IECC: Waarom dit voor u van belang is
De IECC is op grote schaal overgenomen door staten en gemeenten in de gehele Verenigde Staten. De IECC omvat diverse aspecten van het energiegebruik, waaronder de gebouwschil (muren, daken en ramen), verwarmings- en koelsystemen en verlichtingssystemen.
De IECC schrijft specifieke verlichtingsregelingen voor, zoals aanwezigheidssensoren, om energieverspilling in onbezette ruimtes op verschillende locaties tot een minimum te beperken.
ANSI/ASHRAE/IES Standard 90.1, Energy Standard for Sites and Buildings Except Low-Rise Residential Buildings, is een breed erkende energienorm die wordt uitgegeven door de American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).
ASHRAE 90.1: Waarom dit voor u van belang is
ASHRAE 90.1 wordt gebruikt als referentiepunt voor energiecodes voor gebouwen in de gehele Verenigde Staten en dient als een nalevingsroute binnen de IECC. De norm schetst de minimale vereisten voor de energie-efficiënte prestaties van onderdelen van commerciële gebouwen, waaronder gebouwschillen, HVAC-systemen, waterverwarmingssystemen en verlichtingssystemen.
De norm ASHRAE 90.1 specificeert de maximaal toegestane verlichtingsvermogensdichtheden en minimale vereisten voor verlichtingsregeling, waaronder het gebruik van aanwezigheidssensoren in specifieke ruimtes.
Title 24, deel 6 van de California Building Standards Code, officieel bekend als de Building Energy Efficiency Standards for Residential and Nonresidential Buildings, wordt beheerd door de California Energy Commission en wordt periodiek bijgewerkt om nieuwe technologieën en methoden voor energie-efficiëntie te reflecteren.
Title 24: Waarom dit voor u van belang is
Title 24 staat bekend om zijn strenge vereisten, die vaak als strenger worden beschouwd dan die van vele andere energiecodes in de Verenigde Staten. Title 24 schrijft strenge energieprestatie-eisen voor voor alle aspecten van de gebouwconstructie, inclusief verwarming, ventilatie, airconditioning (HVAC), waterverwarming en verlichting.
Title 24 vereist de installatie van aanwezigheidssensoren die de verlichting aanpassen op basis van de bezetting van ruimtes in specifieke gedeelten van commerciële gebouwen om te garanderen dat er geen energie wordt verspild.

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.
