Design Guides and Commissioning Checklists

Practical, product-neutral guidelines for specifying touchless systems, with space planning, sensor placement, signal reliability, maintenance planning, and commissioning checklists to verify performance before occupancy.

In a field where form must follow function, these design guides align architecture, engineering, and facilities stewardship with universal design principles. Drawing on standards and best practices, this section distills complex requirements into actionable steps that support safe, accessible, and sustainable restrooms and wash spaces without compromising aesthetic clarity.

Core Principles for Touchless Commissioning

  • Clear Performance Targets: define response times, sensor sensitivity ranges, and fail-safe modes that ensure reliable operation across diverse user contexts.
  • Accessibility by Design: integrate reach ranges, tactile cues, and alternative feedback to serve users with varying mobility and sensory needs.
  • Maintenance Readiness: specify accessible service access, robust sensor housings, and clear maintenance intervals to sustain hygiene outcomes.
  • Verification Protocols: implement commissioning checklists that document commissioning results, post-occupancy adjustments, and documented recommendations.

Space Planning and Layout

Effective touchless systems begin with thoughtful space planning. Consider user flow, privacy, and maintenance access, ensuring that sensors are positioned to minimize false triggers while preserving intuitive use. Align with universal design guidelines to accommodate diverse users and ensure clear sightlines and unobstructed access paths.

Sensor Placement and Signal Reliability

Document sensor types, mounting heights, and field of view to balance responsiveness with resilience to environmental conditions. Build redundancy into critical interfaces where appropriate, and specify diagnostics that alert facilities staff to drift in performance before it impacts users.

Commissioning Checklist Snapshot

  1. Confirm space dimensions and accessibility clearances align with applicable standards.
  2. Verify sensor type and mounting height meet project specifications for intended use.
  3. Test response times across representative user scenarios and adjust tolerance settings.
  4. Validate feedback mechanisms (visual/audible) function at multiple points of use.
  5. Ensure maintenance access is straightforward and documented in maintenance plans.
  6. Record final sensor readings, thresholds, and anticipated maintenance cadence.
  7. Obtain sign-off from design team and facilities manager prior to occupancy.

Practical Checklists by Discipline

A concise, discipline-aligned set of actions to guide procurement, installation, and verification processes for touchless interfaces.

Architect/Design Lead
  • Define design intent and accessibility targets early in the schematic phase.
  • Coordinate space allowances for sensor housings and maintenance access.
  • Document compatibility with existing building management systems.
MEP Engineer
  • Specify sensor power requirements, wiring routes, and fault-logging features.
  • Assess water and energy implications for faucets and flushing interfaces.
  • Align sensor redundancy with critical-use areas (hospitals, labs).
Facilities Manager
  • Plan preventive maintenance windows and ensure spares inventory is defined.
  • Establish diagnostic dashboards and on-site troubleshooting procedures.
  • Coordinate with custodial staff on maintenance priorities and user communication.
Code Official/Regulator
  • Review alignment with accessibility, electrical safety, and water efficiency codes.
  • Assess documentation completeness for inspection and future audits.
  • Verify performance claims against applicable standards references.
