Solvärmeintaget

Solvärmeintaget, often translated as solar heat gain, refers to the process by which solar radiation enters a building and is absorbed by its surfaces, thus increasing the internal temperature. This phenomenon is a significant factor in a building's energy balance, particularly during warmer months. The amount of solar heat gain is influenced by several factors including the orientation of the building, the size and type of windows, the presence of shading devices, and the thermal properties of the building materials.

In residential and commercial buildings, windows are a primary pathway for solar heat gain. Sunlight passing through transparent surfaces like glass is converted into heat energy as it is absorbed by interior objects and building elements. While solar heat gain can be beneficial in winter by reducing heating costs, it can lead to overheating and increased cooling loads in summer if not properly managed. Architects and building designers employ various strategies to control solar heat gain, such as using low-emissivity coatings on windows, installing overhangs or louvers, and selecting appropriate insulation and roofing materials. Understanding and managing solvärmeintaget is crucial for achieving energy efficiency and maintaining comfortable indoor environments.
