## Building Performance Assessment
Our UVAL systems provide accurate in situ U-value measurements to address key building performance assessment challenges. By enabling real measurements of walls, façades, roofs and more, our systems reveal gaps between designed and actual performance.
The UVAL Wired and UVAL Wireless solutions deliver ISO 9869 measurements of the building envelope, without invasive methods. These reliable systems help identify thermal bridges, insulation defects, and inefficiencies, to provide clear, evidence-based insights into building performance.
## Retrofit Evaluation and Decision
Our UVAL systems support retrofit evaluation by enabling accurate in situ U-value measurement of existing buildings. By taking real measurements before upgrades, professionals can see how well the building is insulated. This helps to understand the true impact on the building envelope.
With UVAL Wired and UVAL Wireless, our ISO 9869 compliant systems provide reliable wall U-value measurements without relying on estimates. This helps reduce uncertainty, validates retrofit performance, and supports confident investment decisions with measurable energy savings.

## Building Envelope and Insulation Development
Our UVAL systems support building envelope and insulation development through accurate in situ U-value measurements of materials under real conditions. This allows for validation and optimized performance beyond initial estimates.
UVAL Wired and UVAL Wireless provide precise wall U-value measurements across a wide range of building materials. They also allow for product validation and improved confidence in building envelope solutions and insulation performance.
## Energy Model Validation
Our UVAL systems improve energy model validation by measuring the thermal performance of buildings. By comparing modeled values with real U-value measurements, building consultants can identify performance gaps and refine simulation assumptions.
UVAL Wired and UVAL Wireless provide precise measurements and façade U-value measurements within building envelopes. Our UVAL systems provide dependable input data, reducing discrepancies between predicted and actual performance and supporting better decisions.
