UVALUE Meaning and
Definition
-
Uvalue, also known as thermal transmittance or heat transfer coefficient, is a measure of the rate of heat loss or gain through a material or structure. It quantifies the amount of heat that can pass through a unit area of a construction element, such as a wall, roof, window, or door.
The Uvalue is typically expressed in units of watts per square meter per degree Celsius (W/m²·°C). It represents the amount of heat energy that flows per second through one square meter of the material or structure when there is a temperature difference of one degree Celsius between the two sides.
A lower Uvalue indicates better insulation properties, meaning that less heat can pass through the material or structure. This translates to reduced energy consumption for heating or cooling and increased thermal efficiency. Conversely, a higher Uvalue implies greater heat transfer and lower insulation performance, which leads to increased energy consumption and decreased efficiency.
Uvalue is an essential parameter in building design, as it helps assess the energy performance and thermal comfort of a structure. It is influenced by various factors such as the type, thickness, and conductivity of the materials used, as well as the presence of insulation layers and air gaps. Building regulations often set maximum Uvalue limits to ensure energy efficiency and thermal comfort standards are met.

Etymology of UVALUE
The term "U-value" is derived from the words "thermal transmittance" or "thermal conductance". The letter "U" in "U-value" stands for "overall heat transfer coefficient". It is a measurement used in building physics and construction to determine the rate of heat transfer through a material or assembly.
