U-value measurement case studies, application examples and other resources

 

Below you will find case studies, white papers and other resources about U-value measurements with the gO Measurement System and the U-Value

Kit. Measurements with these systems enable you to answer questions like: does a building deserver its quality label (Minergie)? Are the walls insulated according to the latest standards? Should the windows be replaced to increase the building's overall energy efficiency? Is the roof well enough insulated? Are heat bridges the cause for mold growth?

Measurements with the gO System and the U-Value Kit generate quantitative data and enable you to make informed decisions. 

U-value and dewpoint assessment with the gO Measurement System

The purpose of this study is to measure the U-value, the temperature and the humidity levels (RH) of the interior of a single-family apartment to examine the influence of these factors to the formation of mold.

U-Value Measurement for Building Standard Verification

In this case study, the u-value of different walls are measured to determine whether the contractor used substandard insulation materials in order to save costs. The measurement was commissioned by the homeowner to get the MINERGIE certification.

Indicators of Insulation Quality: U-value and R-value explained

In order to describe the thermal performance of building elements professionals use R-values and U-values in the same context. Depending on the geographical location and governmental guidelines one or the other term is more popular. This article sums up the main similarities and differences.

U-value measurement in an occupied building

In this case study we present u-value measurements performed in a building while the inhabitants were present. The results allow for an evaluation of the influence of temperature changes on the measurement.

Wall humidity and U-value measurements for mold detection

The purpose of this study is to show how the gO Measurement-System (gOMS) can be used to measure the humidity of the wall and the U-value as well as how the combination of this data can help to analyze and prevent mold growth

Study by the Swiss Federal Office of Energy about calculated and measured U-values

A newly developed device was used to measure the U-values of various wall types built before 1985. The goal was to assess the validity of the embedded U-values in the GEAK calculation model for typical walls that are due for a retrofit. It turns out that walls built before the first model energy codes were implemented (mid-70s) were much lower U-values than those found in the GEAK (only abstract in English)

How heat escapes through the wall 

The heat transfer coefficient (U-value) is a key parameter for planners and builders. Recommendations for renovations proposed by energy consultants are often based on this value. Thanks to a novel method, the U-value of a wall, a roof or a window front can now be determined with a non-invasive method on site. The measurement method can be used to renovate of old buildings and buildings protected under historic presevation laws, a study co-financed by the Swiss Federal Office of Energy shows.

Software tutorial with free test access to the cloud based-software

In this tutorial it is shown step by step how to analyze U-value and aw-Value measurements with the cloud-based online analysis tool. The tutorial is designed as such that it is possible to follow the steps directly at the computer, with the same measurement data, which are taken from a measurement at a camping fridge.
