This isn't wellness folklore. Each pillar in the assessment is anchored to peer-reviewed research and international health standards: the same evidence we design Luxewell homes against.
Consensus recommendations from 18 leading chronobiologists: bright days (melanopic EDI >250 lux), dim evenings (<10 lux in the 3 hours before bed), and true darkness for sleep (<1 lux).
Brown et al., PLOS Biology (2022)Harvard's COGfx studies: every 500 ppm rise in indoor CO₂ slows response times 1.4–1.8%, and every 10 µg/m³ of PM2.5 measurably drags cognition, with no lower threshold where the effect stops. Better ventilation and filtration mean a better-working brain.
Harvard T.H. Chan School of Public Health, The COGfx StudyThe World Health Organization's bedroom guideline is 30 dB LAeq across the eight-hour night, with individual events held under 45 dB LAmax. Sleep disturbance is the health effect those two numbers were set to prevent. The event ceiling is the one most homes fail, and it is the one that glazing, solid-core doors and isolated mechanicals actually buy.
WHO, Guidelines for Community Noise (1999), Table 4.1A five-year study in an occupied building measured unregulated VOCs migrating from PEX-a pipe into drinking water. Migration ran highest in the first months after installation, then fell off sharply and ceased after roughly two years. That opening stretch is the one worth knowing about in a new build, which is why we ask what your pipes are made of. Copper on potable lines is our own design preference, not a finding of this study.
Pelto-Huikko et al., Satakunta University of Applied Sciences; five-year PEX-a migration study (2021)The evidence that a healthier home sells for more is thin. The Global Wellness Institute puts the premium at 10 to 25 percent, from its own analysis of five developments. A measured penalty is better evidenced than a promised premium: when England updated its radon maps, newly flagged homes sold for 0.86% less, and cleared homes showed no measurable gain.
