When the Problem Remains,
We Find Why.
The stain came back.
The odor returned.
The wall is wet again.
The room still feels wrong.
LossPoint provides forensic engineering and root-cause investigation for recurring facility problems including humidity, mold, odor, water intrusion, ceiling condensation, HVAC performance, ventilation and unexplained building conditions — from investigation through verified recovery. The first response addresses the symptom; LossPoint investigates the cause.

The visible symptom may appear simple. The root cause may involve HVAC, ventilation, building envelope, plumbing, moisture, airflow or several systems acting together.
03 — The LossPoint Methodology
The Investigation Is Only the Beginning.
Forensic engineering, root-cause analysis, building performance diagnostics and technical validation in one continuous process — until the recovery is defined and verified.

Why can a cool room still develop condensation?
A simplified public example of how LossPoint presents evidence. It is not a client report and does not reproduce any investigation report or template.
Principal finding
At the illustrative air conditions, the 17.0 °C surface sits −2.1 °C relative to the 19.1 °C dew point, so condensation is physically possible there. The 22.0 °C reference surface stays +2.9 °C above it.
| ID | Quantity | Value | Source |
|---|---|---|---|
| A1 | Air dry-bulb temperature / relative humidity | 25.0 °C / 70% | Illustrative input |
| S1 | Local cold surface temperature | 17.0 °C | Illustrative input |
| S2 | Warmer reference surface temperature | 22.0 °C | Illustrative input |
| C1 | Dew point (from A1) | 19.1 °C | Calculated |
| C2 | Surface margin to dew point (S1 / S2 − C1) | −2.1 °C / +2.9 °C | Calculated |
What this does and does not show
The margin shows that condensation is physically possible at the 17 °C surface under these illustrative conditions. It does not identify the actual moisture source, a mould species or an HVAC fault.
Diagnostic decision
Before choosing a correction, distinguish outdoor-air infiltration, exhaust performance, latent load and cooling operation as contributors.
Validation plan
Repeat comparable temperature, humidity and surface measurements under representative operation after correction. No after-correction results are shown here.
Calculation basis
Magnus approximation, a = 17.625, b = 243.04 °C, T = air temperature (°C), RH in %.
γ = ln(RH/100) + aT / (b + T)
DP = b·γ / (a − γ)
Margin = Ts − DP
An approximation for typical atmospheric building conditions. Instrument uncertainty is not stated because no actual sensor was used.
Background reading: Vaisala — relative humidity, dew point and mixing ratio
Explains how dew point follows from air temperature and humidity and why surfaces below it can condense. Cited for explanation only; no endorsement implied.

Scope and deliverables are agreed case by case.
Discuss your condition →Common questions
What does an investigation cover?
Scope is agreed case by case after we review your enquiry: the areas, systems and questions to be examined.
What access do you need?
Access to the affected areas and, where useful, comparable unaffected areas and the related equipment, coordinated with your team.
Can you work while the building is occupied?
Usually, yes. Measurements under representative operation are often what the investigation needs; timing is planned with you.
Do you work with our maintenance team?
Yes. Your team’s history of the problem is part of the evidence, and corrective work may be carried out by your team, LossPoint or an authorized specialist.
04 — Where We Work
Different Facilities. The Same Need for Certainty.
Hotels & Resorts
Guest room humidity, odor, stains, water intrusion and comfort complaints can repeatedly remove rooms from service.
Healthcare
Some patient rooms or controlled areas may not maintain consistent temperature, humidity, airflow or pressure conditions.
Manufacturing / Industrial
Temperature, humidity and process-area airflow can vary significantly across production areas.
Warehouse / Storage
Areas of the same facility can expose inventory to very different storage temperature, humidity and airflow conditions.
Government / Institutional
Recurring moisture, odor, comfort or ventilation problems can affect public buildings long after repeated maintenance interventions.
Commercial Facilities
Occupants often experience discomfort, odor or poor indoor air quality before the technical cause is obvious.
Restaurants & Food Service
Heat, moisture and equipment loads can create very different conditions within the same operation.
Residential / Multi-Unit
Residents experience moisture, odor, temperature and water intrusion as one building problem — not as separate systems.

Prioritize affected areas, determine where corrective action is needed and verify that the environment was restored.
Manufacturing / Industrial
Process-Area Environmental Performance
Heat, humidity, airflow or building conditions vary across production areas and may affect process stability, product behavior, equipment or worker conditions.
Map environmental differences by zone and determine how the building and systems are influencing the process environment.
Modify zone use, ventilation, process placement or corrective priorities based on measured conditions.
Warehouse / Storage
Storage-Zone Performance Mapping
Different areas of the same warehouse may expose inventory to significantly different temperature, humidity or airflow conditions.
Identify stable, unstable, stagnant and high-exposure zones.
Determine where inventory should be stored, rotated or avoided, and where environmental improvements are required.
Government / Institutional
Building Performance Across Occupied Areas
Some offices, archives, classrooms, public areas or technical rooms repeatedly experience moisture, odor, comfort or ventilation problems.
