Restrooms
探索我們的洗手間能源效益指南，旨在幫助您瞭解並實施感應器解決方案，以符合美國能源法規並實現高效照明控制。
Maximize Energy Efficiency in Restrooms with Occupancy Sensors
Restrooms in commercial buildings are frequently used spaces that often remain lit even when unoccupied, leading to significant energy wastage. These spaces typically use high-intensity lighting fixtures that consume substantial amounts of energy. The sporadic and unpredictable nature of restroom usage further exacerbates this issue, as lights are often left on unnecessarily during periods of non-use.
Given these factors, the potential for energy savings in restrooms is substantial. By implementing occupancy sensor solutions, commercial facilities can significantly reduce their lighting energy consumption. Occupancy sensors detect the presence or absence of people and automatically control the lighting accordingly, ensuring lights are only on when needed. This not only saves energy but also extends the lifespan of lighting fixtures, leading to additional cost savings.
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。

洗手間設計指南關鍵概念
為洗手間設計節能照明控制方案時，需要策略性地佈置佔用感應器，以確保全面覆蓋整個空間。
By following these guidelines, businesses can create an energy-efficient lighting control solution for restrooms that reduces energy waste, and lowers maintenance costs:
- Entrance Coverage: Install a wall occupancy sensor near the entrance to detect when someone enters the restroom. This sensor should be positioned high enough to avoid obstructions from the door and should not directly face the entrance to avoid false triggers from movement outside the restroom.
- Stall Coverage: Depending on customer preference for privacy, stalls can either be covered by a sensor or not. If stalls are not covered by a sensor, program a longer timeout (15 or 20 minutes) to prevent lights from turning off when someone is in the stall. If individual stall sensors are used, they should be installed in such a way that they do not detect movement outside the stall to avoid false triggers.
- Sink and Mirror Area: Install a ceiling occupancy sensor above the sink and mirror area. This sensor should be positioned to cover the entire area, ensuring that lights remain on when someone is using the sink or mirror.
- Avoidance of Air Vents: Do not mount sensors close to air vents, as the vibration and air flow can reduce the effectiveness of the sensor. PIR sensors should not be within 4ft of an air vent, and ultrasonic sensors should not be within 6ft of an air vent.
- Manual Control: Integrate manual control to turn ON/OFF all lighting with our occupancy/vacancy sensors. This allows for manual override of the lighting system if necessary.
