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.
符合能源法規
《國際能源節約規範》（International Energy Conservation Code，簡稱 IECC）是由國際規範委員會（International Code Council，簡稱 ICC）制定的示範規範，旨在確立建築物能源效益的最低設計與建造要求。IECC 每三年更新一次，以納入最新的能源節約實踐與技術。
IECC：為何您需要關注
IECC 已被美國各州和地方政府廣泛採用。IECC 涵蓋能源使用的多個方面，包括建築外圍結構（牆壁、屋頂和窗戶）、供暖與制冷系統，以及照明系統。
IECC 強制要求使用特定的照明控制設備（例如佔用感應器），以最大限度地減少各區域無人空間的能源浪費。
ANSI/ASHRAE/IES Standard 90.1（除低層住宅建築外的地點與建築能源標準）是由美國採暖、制冷與空調工程師學會（ASHRAE）發布的廣受認可之能源標準。
ASHRAE 90.1：為何您需要關注
ASHRAE 90.1 被用作全美建築能源法規的基準，並作為 IECC 內部的合規途徑，其中概述了商業建築組件（包括建築外圍結構、HVAC 系統、水加熱系統和照明系統）能源效益表現的最低要求。
ASHRAE 90.1 標準規定了最大允許照明功率密度和最低照明控制要求，包括在特定區域使用佔用感應器。
Title 24 為加州建築標準法規第 6 部分，官方稱為《住宅與非住宅建築能源效益標準》。Title 24 由加州能源委員會管理，並定期更新以反映新的能源效益技術與方法。
Title 24：為何您需要關注
Title 24 以其嚴格的要求而聞名，通常被認為比美國許多其他能源法規更為嚴格。Title 24 對建築施工的所有方面（包括供暖、通風、空調 (HVAC)、水加熱和照明）都制定了嚴格的能源表現標準。
Title 24 要求在商業建築的特定區域安裝佔用感應器，根據房間的佔用情況調節燈光，以確保不會浪費能源。

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.
