Who this report is for.
Considering this address
Maps the environmental reality of the place — what the air, water, and surroundings are doing biologically, and what your first impressions are picking up on.
Already live here
Shows you the full picture of where you are — what's working in your favor, what deserves attention, and specific things you can do this week.
Thinking about leaving
Gives you an honest read of what this place has been doing to you. Sometimes the environment is exactly the reason. Sometimes it isn't. This tells you which.
What this report measures — and why it matters.
Your experience of this space is data too.
Before the report generates, we ask you eight questions about what you've actually noticed here — how you sleep, how the air feels, what your body has been picking up that you haven't quite named yet.
That layer gets woven into the report alongside the public data. The body is the most sensitive instrument available. This is where it gets to speak.
What the report looks like.
Actual report — 301 Knob Hill Ave, Redondo Beach, CA. Your report uses your address data.
What this report actually tells you.
If the PM2.5 annual average at this address exceeds health guidelines, you'll learn the specific filtration capacity needed and which room matters most. If a cell tower sits within close range of the sleeping areas, you'll learn what that means for melatonin and what a single positioning change does about it. If RCRA hazardous waste handlers were identified nearby, you'll know each one by name and what they handle. If the water system uses chloramine, you'll get the specific filter media that removes it.
The map makes the invisible visible: every flagged facility, every hazard, every asset — placed exactly where it sits relative to your address.
And the report is equally specific about what works in your favor — the coast, the farmers market, the parks, the bike infrastructure — each one named, located, and explained for what it actually does biologically when you use it.

Built by a building biologist.
Allan Lopes is the founder of the Healthy Building Certificate — a building biology framework practiced across the US and Brazil. Building biology is the discipline of understanding how the physical environment of a home affects the biology of the people inside it.
The Blue List is the environmental health framework behind everything in this report — developed by Allan over 25 years of practice and used worldwide to define what a genuinely healthy built environment looks like.
From people who've been through it.
"I'd been living in my apartment for three years and couldn't understand why I was constantly tired and had recurring headaches. I assumed it was work stress. Allan's assessment found elevated formaldehyde levels from cabinetry installed during a recent renovation. Once I understood what was happening and made the changes he recommended, things shifted within weeks."

"I was considering leaving my neighborhood because I felt like I wasn't living as healthily as I wanted to. Allan's assessment showed me I was actually in a remarkably strong environment. What I needed wasn't a new address — I needed to actually use what was already around me. That reframe changed everything."

"We were about to commit to a home we loved. Allan's assessment identified an industrial facility nearby that we had no idea existed, and explained exactly what it produced and what that meant for the air and soil. We didn't walk away — we went in with full information and made specific changes before moving in."
