lämpövuotokokeen

Lämpövuotokoe, often translated as a heat loss test or thermal leak test, is a method used to assess the thermal insulation properties of a building or a specific component. It is a crucial part of energy efficiency evaluations and building diagnostics. The primary goal of a lämpövuotokoe is to identify areas where heat is escaping from a building during colder months or entering during warmer months, indicating poor insulation or air leakage.

The test is typically conducted using infrared thermography. An infrared camera is used to capture images of the building's surfaces, both internally and externally. Different temperatures are represented by different colors on the thermal image, allowing for the visualization of temperature variations. Areas that appear significantly colder on the interior or warmer on the exterior during heating season are likely points of heat loss. Conversely, during cooling season, warmer interior spots can indicate heat gain.

Common issues detected by a lämpövuotokoe include inadequate insulation in walls, attics, and floors, as well as air leaks around windows, doors, electrical outlets, and structural joints. These leaks can not only lead to significant energy waste but also contribute to moisture problems, drafts, and reduced indoor comfort. The results of a lämpövuotokoe provide valuable information for homeowners and building professionals to pinpoint areas requiring improvement, such as adding insulation or sealing air leaks, thereby enhancing the building's thermal performance and reducing energy consumption.
