U-value measurements of different windows and a wall of different constructions
Session
Energy Efficiency Engineering
Description
In the modern era, due to the continuous increase in demand for higher housing comfort, energy consumption in construction has increased too.
While in an industrial country such as Switzerland the energy going into construction accounts for over 50% of all energy consumed, in Kosovo in a country far less economically and industrially developed than Switzerland, at least 70-80% of energy is spent on buildings.
Energy efficiency in construction and a well thought out and well studied energy supply policy of the country are crucial factors for its economic development.
In addition to other relevant factors (shape, object orientation, etc.), construction efficiency also depends on the type of construction and insulation materials used.
The efficiency of insulation materials is defined by thermal conductivity or Lambda value (W/mK).
In addition to theoretical calculations, we have explored the impact of these materials on efficiency by measuring the U-value with particular emphasis on different windows and exterior walls. The measurements were carried out using a special apparatus of the GreenTeg company from Zürichu. This apparatus has been developed in collaboration with ETH Zürich.
These measurements have made effort into showing how the U value (or U coefficient) (W/m2K) changes and how different types of windows and different exterior wall insulation materials affect construction efficiency. These measurements are important before or even after renovations. In addition, with these measurements we can ascertain the energy performance and the economic calculation of these renovation measures.
