WebOne of the most important facets is the window’s ‘ U-value ‘. The U-value measures how well heat is transferred in or out of a building. The certified Passive House standards state that U-values for windows should be below 0.8 W/ (m²K). How … WebA U-value is used to measure the thermal efficiency of the window. The lower the U-value the better the thermal performance. A Passivhaus window must achieve a whole window U-value of 0.80W/m2k. This low U-value keeps the internal temperature of the window at a comfortable level, removing any need to provide a heat source close to the window.
