Building sector emissions are high worldwide. Measures that improve energy efficiency are important in the context of climate protection. There’s also great potential for savings on energy costs in older building stock as well as industrial and commercial premises. But where does one begin? With a thorough analysis. uvalgt Building produces reliable and precise U-value calculations without drilling or related damage to building materials.
Heat flux works according to the physical law of heat transfer. By measuring the U-value, it’s possible to calculate the heat flux flowing through a structural element, such as a wall, door or window. The U-value is directly proportional to the difference between the warm and cold sides and is measured in units of W/(m²K). It provides insights into a component’s insulating properties. The lower the U-value, the better the insulation.
A U-value measurement is used wherever heat loss is to be evaluated or thermal bridges found. It allows conclusions to be drawn about a building’s energy balance so that useful renovations can be planned. A U-value measurement is also needed to prove eligibility for certain grants and subsidies. Measurements taken using the uvalgt wireless kit guarantee useful data for informed decisions.
What exactly is the heat transfer coefficient and how is it measured? We’ve included everything you need to know about the U-value here, along with information on using our smart uval® solutions – from evaluating building insulation to monitoring the performance of effective building envelopes.
