Frequently Asked Questions
What protocol for a sale / rental?
We first define the objective (sale, rental, dispute, renovation) then a simple protocol: rooms to measure (often living room + bedroom), box positioning and duration. The report then provides a summary and detailed analysis.
What duration do you recommend depending on the case?
24h is enough for a first day/night snapshot. 48h increases robustness. 1 week is ideal to capture variability (weekend, traffic, neighborhood) and obtain a more stable diagnosis.
How to standardize across a portfolio?
We set up a single protocol (duration, rooms, positioning, reading criteria) to compare properties. This allows prioritizing actions, tracking impact after work and industrializing report production.
Is the report usable for a file?
Yes: it is structured, timestamped, and designed to be shared (clear PDF + annexes as needed). It serves as a factual basis for discussion, conciliation, or to prepare a more technical approach if necessary.
What to do if the score is low?
The APD doesn't stop at the score: it highlights critical moments and probable causes. Above all, you receive a prioritized action plan (layouts, adjustments, work) to improve the situation in a targeted way.
Can we compare several properties?
Yes, especially if the duration and protocol are identical. The score, day/night indicators, peak frequency and nuisance typology allow simple and objective comparison.
How do you guarantee confidentiality?
"Privacy-first" approach: no camera, diagnostic purpose, limited duration and controlled parameters. Results are presented as indicators and nuisance categories, not as an occupant monitoring tool.
Where do you operate?
We operate throughout France. Depending on the project, we can also operate remotely (box shipment + guided protocol), especially for multi-site deployments.
