The Verified Home: When Design Graduates Into Evidence

Most luxury homes “feel” healthy. Few can prove it. A verified home treats biology like a design requirement, not a vibe. That means measurable targets for the invisible systems air, water, light, acoustics, and electrical paired with a verification protocol at handover. Verification is what separates marketing from accountability.

At MAVI, verification begins long before the first filter is delivered. We align standards at pre-construction, translate them into drawings, and set clear pass/fail thresholds. Our headline targets summarise what buyers actually care about: bedrooms that hold CO₂ under 800 ppm overnight, VOCs under 300–500 µg/m³ at handover, and bedrooms that actually sit at 17–19 °C with 40–60% relative humidity (RH). Your nervous system reads those signals before you do. We design the test, not just the spec: demand-controlled ventilation is commissioned with a CO₂ decay test from 1500 → 800 ppm in 30–45 minutes, logged at handover.

How we make it stick:

Diagnostics → Design. Site and environmental risks are mapped (radon zones, legacy contaminants, external noise, etc.), with remediation and testing plans set early, not after finishes are chosen. MAVI’s stage-gated checklists keep these decisions visible across design, installation, and in-use service.

Spec with limits, not slogans. We write numerical limits into drawings and submittals: flicker thresholds (PstLM ≤1.0, SVM ≤0.4) with on-site meter checks, pre-programmed lighting scenes, and bedroom blackout with verified lux readings at night. Circadian performance is quantified via melanopic EDI—≥ 250 by day, ≤ 20 in the evening.

Handover with receipts. Ducts are cleaned, sacrificial filters swapped, the home is flushed with 100% outdoor air for 72 hours, and pre-occupancy IAQ tests confirm targets before keys change hands. It’s all logged with as-builts, commissioning certificates, product manuals, and a resident education session.

Water follows the same discipline: whole-home sediment + carbon filtration, POU RO with remineralisation (Ca/Mg), Legionella temperature and layout controls, and appropriate fixture selections. We commission hot water storage at ≥60 °C, verify draw-off temperatures, and include a filter replacement schedule in the handover pack then check annually.

Light is verified too. We start with daylight analysis and track it through concept to technical design, then commission controls and pre-set scenes at handover. Post-install checks confirm illuminance and flicker; bedrooms get true blackout (side channels, LED covers) to protect darkness at night.

Acoustics are treated as biology, not background. Bedrooms are commissioned to ≤30 dB LAeq,8h and ≤45 dB LAFmax; living areas to ≤35 dB LAeq. Reverberation is tuned to T60 ≤0.5 s, and HVAC noise held to NR 25–30 in bedrooms. Field tests confirm performance and help close any last gaps.

Even electrical planning gets biological: keep routers ≥2 m from beds, hard-wire data to bedrooms, add a night cut-scene to de-energise sockets/USBs while leaving life-safety live, and verify harmonic distortion ≤5% per accepted guidance. Commission with bonding tests, harmonics measurements, and a controls demo at handover.

Why it matters: buyers aren’t just purchasing surfaces; they’re buying outcomes: clearer air, steadier sleep, calmer decision-making. A verified home gives them and your team objective proof. And because verification is woven through design and delivery (not bolted on), it protects schedules and de-risks substitution. Post-completion, MAVI Metrics can continue to monitor air, water, light, thermal and acoustic data so performance (and trust) compounds over time.

This is the difference between “healthy-looking” and biologically accountable. The former is marketing. The latter is MAVI.
