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.
Overhold energireglementerne
International Energy Conservation Code (IECC) er en modelstandard udviklet af International Code Council (ICC) med henblik på at fastsætte minimumskrav til projektering og udførelse for energieffektivitet i bygninger. IECC opdateres hvert tredje år for at integrere de nyeste praksisser og teknologier inden for energibesparelse.
IECC – Hvorfor det er vigtigt for dig
IECC er udbredt i delstater og kommuner over hele USA. IECC dækker forskellige aspekter af energiforbrug, herunder klimaskærmen (vægge, tag og vinduer), varme- og kølesystemer samt belysningsanlæg.
IECC stiller krav om specifikke belysningsstyringer, såsom tilstedeværelsessensorer, for at minimere energispild i ubrugte rum på tværs af forskellige områder.
ANSI/ASHRAE/IES Standard 90.1, Energy Standard for Sites and Buildings Except Low-Rise Residential Buildings, er en vidt anerkendt energistandard udgivet af American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).
ASHRAE 90.1 – Hvorfor det er vigtigt for dig
ASHRAE 90.1 anvendes som reference for bygningsreglementer i hele USA og fungerer som en overholdelsesmetode inden for IECC, der opstiller minimumskrav til energieffektive ydelser i erhvervsbygningers komponenter, herunder klimaskærme, HVAC-systemer, brugsvandssystemer og belysningsanlæg.
ASHRAE 90.1-standarden angiver maksimalt tilladte belysningseffekttætheder og minimumskrav til belysningsstyring, herunder brugen af tilstedeværelsessensorer i specifikke områder.
Title 24, del 6 af California Building Standards Code, officielt kendt som Building Energy Efficiency Standards for Residential and Nonresidential Buildings, Title 24 administreres af California Energy Commission og opdateres med jævne mellemrum for at afspejle nye teknologier og metoder inden for energieffektivitet.
Title 24 – Hvorfor det er vigtigt for dig
Title 24 er kendt for sine strenge krav, der ofte anses for at være mere vidtgående end kravene i mange andre energireglementer i USA. Title 24 opstiller strenge energiydelsesstandarder for alle aspekter af bygningskonstruktion, hvilket omfatter opvarmning, ventilation, aircondition (HVAC), brugsvand og belysning.
Title 24 kræver installation af tilstedeværelsessensorer, der tilpasser belysningen baseret på personers tilstedeværelse i specifikke områder af erhvervsbygninger for at sikre, at der ikke spildes energi.

Design Guide Key Concepts for Restrooms
Designing an energy-efficient lighting control solution for restrooms involves strategic placement of occupancy sensors to ensure comprehensive coverage of the space.
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.
