Marketing strategy summary was built for U-Value Kit (measures the insulation quality of a building).
Estimated time – 2 weeks.
Heat Flux Sensor and two temperature sensors. This approach is standardized in ISO 9869, ASTM C1046 and ASTM C1155
1. Table Look-up (Building Catalogue)/ U-Value Calculation
There are complex databases containing λ-Values of generic building elements ordered by element material and/or year of construction. With these databases, the U-value of a building envelope (e.g. wall) is calculated by adding all materials contained within the specific element (e.g. specific wall = 20cm concrete + 20cm glass wool). While this method is very simple and quick, it does not produce an accurate U-Value, only an approximation.
2. Thermography (i.e. Infrared imaging)
This approach shows the thermal radiation of an object and produces an image showing spots with higher and lower radiation. It does not produce a U-Value, it just produces an image.
3. Multiple Temperature Measurement
This approach is based on three or more temperature measurements on both inside and outside of a building element. While this approach produces a U-Value, it needs a minimum temperature difference of 10 °C between the inside and outside to work and it is assumend that the thermal boundary resistance is constant.
