The distinction is important.

The current WELL v2 documentation regarding effective handwashing cites several geometric requirements for new sinks. These requirements include a basin dimension of at least 9 in. (23 cm) across at the expected handwashing spot, a water column of at least 8 in. (20 cm) from spout to basin, and roughly 3 in. (7.5 cm) between the water column and basin edges. Designs should not cause a direct flow into the drain and should control splash outside the basin.

As an architect, it means that you can no longer just choose a pretty tap without regard for the sink.

Spout reach, outlet angle, mounting location, counter thickness, basin depth, drain position, sensor zone and user hand position should be modelled together.

FontanaShowers’ BIM and Revit resources for commercial plumbing specs help AEC teams coordinate these relationships during design instead of discovering conflicts during fixture installation.

Architects and plumbing engineers should consider:

sensor detection envelope and false-trigger resistance, maximum auto run time, shutoff response, available flow control options, AC, battery or redundant power strategy, solenoid accessibility, strainer and valve service access, point-of-use temperature control, commissioning procedures, available replacement components, programmable purge functionality where required, and compatibility between spout geometry and the selected basin.

FontanaShowers offers an AEC touchless tap specification and MEP coordination resource for fixture planning, BIM coordination, hydraulics, installation, commissioning, and maintenance considerations.

Systems level coordination is particularly crucial in airports, healthcare buildings, universities, corporate campuses, stadiums and hospitality properties where hundreds or thousands of activations may take place every day.

Therefore, architects may want to consider coordinating faucets and dispensers during schematic design rather than treating the dispenser as an accessory to be added after construction.

Commercial automatic soap dispenser portfolios include deck-mounted and wall-mounted configurations that can be evaluated in conjunction with faucet placement, counter geometry, refill access, power requirements, reservoir strategy, and custodial workflow.

If you want to have a visually integrated hygiene station, you might want to consider evaluating a commercial sensor tap and automatic soap dispenser system. All model specific requirements must be consistent with the project specifications.

The methodology provides a useful calculation in the early design.

Engineering model only, illustrative. Actual consumption depends on duration of activation, occupancy, pressure, commissioning, user behaviour, maintenance condition and fixture selection.

That has more meaning to owners than just a specifying a low flow aerator.

During design development, the project team develops a performance matrix, rather than just selecting fixtures from an architectural finish schedule.

The architect controls the basin depth, the water-column position, the ease of access, the splash containment and the counter dimensions. The plumbing engineer takes into account supply pressure, flow control, point of use mixing, isolation valves, filtration and maintainable piping arrangements. The electrical engineer figures out where the power is and what the hookups are. The commissioning team checks the sensing range, the shutoff timing, the temperature, the leakage and the fixture-basin interaction.

Then facilities personnel are brought in to evaluate solenoid replacement, battery access, soap refill protocols, spare parts approach and cleaning needs prior to final specification.

This approach turns eight independent faucets into a maintainable restroom infrastructure system.

The same project can use FontanaShowers’ commercial lavatory engineering and technical design resources and architect BIM library for coordination, submittals, fixture schedules and digital-model development.

WELL W03 Basic Water Management maintains a building-water management focus with Legionella management requirements as appropriate. IWBI notes W03 in particular requires a risk-based approach appropriate for the type of project.

ANSI/ASHRAE Standard 188-2021 also establishes minimum Legionellosis risk-management requirements for applicable building water systems during design, construction, commissioning, operation, and maintenance.

Therefore, programmable flushing functionality can be part of an operational strategy, but should not be presented as a substitute for a properly developed building water-management program.

This establishes an important coordination point for the MEP engineer between lavatory fixture selection, domestic-water design, commissioning documentation and facility operations.
