The number that defines how biologically functional your property is.
Noon developed the Sensory Environment Score to answer a question no other metric addresses: what is this property doing to the human living on it?
Scored across five dimensions of human evolutionary biology, the score runs from 0 to 100. Most modern properties score between 8 and 22. The Noon Baseline — the sensory conditions humans evolved to thrive inside — requires 80+.
Moving water at 52 dB suppresses cortisol and activates parasympathetic response within 7 minutes.
Recirculating channels and bioswale water movement — acoustic infrastructure first.
Dappled canopy light triggers serotonin production and maintains circadian anchoring that indoor environments destroy.
Eastern pergolas for morning light. Western shade for thermal management. Sky access zones.
Moving between warm sun and cool shade activates metabolic systems and cardiovascular regulation that single-temperature environments suppress.
Three-zone thermal design: sun / transition / deep shade with evaporative cooling.
Mycobacterium vaccae in bioactive soil activates serotonin pathways through skin contact. Treated turf eliminates it entirely.
Bioactive native soil zones, barefoot pathways, compost-integrated growing beds.
Foraging and harvesting activate dopamine reward cycles that passive exercise cannot replicate. Your body expects functional terrain, not decorative space.
Foraging circuits, harvest loops, varied terrain, daily physical engagement tasks.
