A room-by-room assessment of your home's indoor health, built on the Baubiologie framework used by building biology consultants across Europe.
Most of us spend over 20 hours a day indoors. The materials in our walls, floors, and furnishings shape the air we breathe, the light we absorb, and the moisture our rooms hold. Some of these effects are obvious (a fresh-paint smell that lingers for weeks). Others are invisible (electromagnetic fields from wiring behind plasterboard, or mould spores behind bathroom tiles).
The Full Assessment helps you see what's happening in your home, room by room, so you can make informed decisions about what to change and what to leave alone.
Pick a room and work through 12–18 questions about your materials, ventilation, lighting, humidity, and habits. The questions are grouped by three pillars: physical environment (EMF, radiation, light quality), chemical exposure (VOCs, material off-gassing), and biological factors (moisture, mould risk, allergens). You can save your progress and return later.
Each room receives a score from 0 to 100. Scores above 80 indicate a nature-aligned environment. Between 50 and 79, there are areas worth attention. Below 50, specific actions are recommended. If the assessment detects critical issues (visible mould, persistent chemical odours, or lead/asbestos risk), it flags these immediately.
Your results include a list of specific improvements, ranked by impact and sorted by estimated cost and complexity. Each recommendation links to relevant products in our shop and to educational content explaining the science behind the suggestion.
Everything is compiled into a branded PDF report with your scores, pillar breakdowns, renovation priorities, product recommendations, and scientific citations. You can also email the results to yourself or print them.
Your personal report covers every room you assess and includes:
The report is yours to keep. Access never expires, and you can reassess rooms as you make changes to track your progress over time.

A professional building biology assessment costs €500 or more and can take a full day. Our tool uses the same Baubiologie framework in a guided digital format, covering bedroom, nursery, kitchen, and bathroom. That works out to less than €5 per room assessed.
Payment is handled securely through our shop. Your account is created automatically at checkout.
Every purchase supports Nordnatur's work to make building material health data more accessible across Europe. We're developing open tools for structured product transparency, including the Digital Product Passports that EU regulation now requires for construction materials. The same research that powers this assessment feeds that wider effort.
Each room takes about 15–20 minutes. You can save your progress and return at any time. Most people assess one or two rooms in their first session and come back for the rest.
No. The questions are based on observation and the information you already know about your home (what materials are present, how old they are, whether you notice symptoms). It's a structured self-assessment, not a measurement tool.
An account is created for you automatically during checkout. You'll be redirected straight to the assessment, where you can choose which room to start with. No waiting, no confirmation emails to click.
No. The assessment identifies material-related health factors in your home based on building biology principles. It's an awareness and decision-making tool, not a medical or regulatory instrument. For persistent health concerns, we recommend consulting a healthcare professional or a certified building biologist.
