What is a U-Value?

A U-Value calculation is used to quantify the amount of heat that is transferred and lost through any thermal element of a building (walls, floors, roofs). The quantity of heat that is transferred is dependent on the thickness and thermal conductivity of each element.

By proving how effective a building is keeps hold of its heat, we are able to demonstrate the lessening need for excessive energy consumption. U-value’s form an integral part of the SAP assessment and each element of the building must have its own particular u-value assigned.

The more difficult it is for heat to transfer through a thermal element, the lower the U-value of that element will be. When it comes to energy efficiency and the overall carbon footprint of your building the lower the U-value of its thermal components the better. Our experienced surveyors will assess each thermal component, such as a pane of glass, a door or a cavity wall and will calculate the U-value. This will be based on the amount of energy that is lost through a square metre of that particular building component.
