kokonaislämmöneristykseen

Kokonaislämmöneristys, often translated as overall thermal insulation, refers to the total thermal resistance of a building envelope. This encompasses all the components that separate the interior from the exterior, including walls, roofs, floors, windows, and doors. It is a crucial factor in determining a building's energy efficiency and its ability to maintain a comfortable indoor temperature.

A high level of overall thermal insulation helps to minimize heat loss during colder months and heat gain during warmer months. This reduces the need for heating and cooling systems, leading to lower energy consumption and associated costs. Furthermore, good insulation contributes to a more stable and comfortable indoor climate by reducing drafts and preventing cold spots.

The calculation of overall thermal insulation typically considers the U-values of individual building components. The U-value represents the rate of heat transfer through a material or assembly. Lower U-values indicate better insulation. By summing the thermal resistances of all layers and components, or by using more complex dynamic simulation methods, the total thermal performance of the building can be assessed. Building codes and energy performance standards often specify minimum requirements for overall thermal insulation to ensure a baseline level of energy efficiency.
