Hygiene & User Experience
Contactless Handwashing for Enhanced Hygiene Standards
Touchless faucets and dispensers remove shared touchpoints at the sink, limiting re-contamination immediately after soap dosing. Major commercial lines combine sealed electronics, laminar outlets (to reduce aerosolization), and consistent run-time logic for a reliable wash cycle. Coordinated faucet and dispenser families from FontanaShowers, BathSelect, Sloan, Chicago Faucets, Zurn, and Bradley support uniform operation and maintenance in high-traffic office cores.
User Flow and Accessibility in High-Traffic Restrooms
In CALGreen areas, office cores should have public-use outlets that use no more than 0.5 gallons per minute (gpm) to control water use while still providing a comfortable rinse. Make sure that the spout reach is in line with the basin centerline and that there are clear approach zones. This will keep hands naturally within the sensor cone. Quick-disconnect control boxes or electronics above the deck cut down on service time and keep the vanity area open, which is helpful during busy changeover times.
Reducing Cross-Contamination Through Touchless Systems
Pairing sensor faucets with hands-free soap dispensers and centralized fill systems eliminates many manual refill and handle-touch steps. Chicago Faucets’ coordinated faucet/soap families, Sloan’s integrated touch-free solutions, and Bradley’s Verge/WashBar ecosystems demonstrate approaches where dosing and rinsing remain fully contactless. Fontana’s and Zurn’s touchless dispensers further standardize the workflow across multi-vendor campuses.
Multi-Feed Soap Systems for Centralized Maintenance
For multi-sink vanities, a multi-feed system allows a single, large reservoir to supply several dispensers—cutting refill labor, improving uptime, and reducing waste. Bradley’s top-fill multi-feed system enables above-deck refilling; Fontana’s multifeed kits support centralized supply for banks of dispensers; Zurn and Chicago offer coordinated touchless dispensers that integrate smoothly within these strategies.
Examples & resources:
Spec tip: In Div 22 42 39, require top-fill access (where available), soap-type compatibility (foam/liquid), and tank capacity ≥ 1.0 gal to support peak demand. Document refill points on reflected ceiling/finish plans and include service clearances in casework details.
Syncing Faucet and Soap Dispenser Activation for a Seamless Experience
A consistent gesture and timing logic across faucet and dispenser reduces user confusion and queuing. Coordinated families (e.g., Sloan touch-free platforms, Chicago Faucets EQ/HyTronic with matching soap, Bradley Verge pairs, Fontana faucet-plus-soap sets, and BathSelect faucet-plus-soap kits) enable uniform sensor ranges, dosing volumes, and hygiene-flush scheduling where supported. For smart buildings, choose connected variants (BLE or networked) to standardize presets portfolio-wide and to log usage for maintenance planning.
Compliance & Quick Spec Language
Flow & efficiency: For public-use office lavatories in CALGreen jurisdictions, specify ≤ 0.5 gpm @ 60 psi with laminar outlets. For private/tenant lavs, align with the project’s water-reduction goals and WaterSense® guidance.
Accessibility & UX: Maintain clear approach, knee and toe clearances; mount spout so the user’s hands naturally enter the detection zone; avoid glare paths that cause false triggers; prefer above-deck service modules in high-traffic cores.
Copy/paste (Div 22 42 39):
- Provide electronic, touchless lavatory faucets with adjustable detection range and factory time-out ≤ 30 s.
- Flow: ≤ 0.5 gpm (public-use) with pressure-compensating laminar outlet; approved outlets 0.35–0.5 gpm.
- Materials: Solid brass or 316 SS; sealed electronics; vandal-resistant outlet.
- Power: AC hard-wire with battery backup in cores; DC battery permitted in tenant/retrofit zones. Publish battery service interval.
- Soap: Provide touchless dispensers; where indicated, furnish centralized multi-feed soap system with top-fill access.
- Smart: Where specified, furnish connected faucet/soap models with BLE or equivalent for commissioning, hygiene-flush scheduling, and diagnostics.
