Develop a marketing strategy for U-Value Kit.
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.
greenTEG AG was founded in 2009 as a spin-off of the Swiss Federal Institute of Technology (ETH). The company develops, manufactures, and markets thermal sensors for heat flux and laser power/position measurements and provides consulting on the thermal integration of its products.
Today, greenTEG supplies OEMs as well as scientists in corporate and university labs around the world with its unique products. The greenTEG team consists of 15 specialists in engineering, materials science, physics, and electric engineering. All sensors are fully developed and manufactured in Zurich, Switzerland.
Typical application areas include measurement of building insulation, windows, and various industry driven R&D fields.
Thermal energy enters buildings mainly from the heating system and from solar irradiation. The energy exchange between the building and the outside is focused through the roof, walls, windows, and thermal bridges e.g. balconies, into the soil, and through exchange of ambient air. Every building is a complex thermal system and to optimize these systems (for example to reduce heating costs), precise data is required.
As the measurement set up for glass differs due its low thermal capacity to the influence of radiation for opaque materials. Our U-Value-Kit can also be easily installed to measure the U-Value of windows.
