Lämpövuotoille

Lämpövuotoille refers to heat loss in buildings. It is the uncontrolled flow of heat from a warmer indoor environment to a cooler outdoor environment during colder months, or in reverse during warmer months. This phenomenon is a significant factor in energy consumption and the thermal comfort of occupants. Identifying and mitigating lämpövuotoille is crucial for energy efficiency and reducing heating and cooling costs.

Common areas for lämpövuotoille include gaps around windows and doors, poorly insulated walls and attics, and penetrations through the building envelope such as electrical outlets, plumbing, and ventilation systems. Air leakage is a primary mechanism for heat transfer, carrying heat and moisture with it.

Methods to address lämpövuotoille involve improving the building's thermal insulation and air sealing. Insulation materials like fiberglass, mineral wool, or spray foam are installed in walls, ceilings, and floors to resist heat flow. Air sealing techniques, such as caulk and weatherstripping, are used to close cracks and openings, preventing drafts and heat loss. Blower door tests are often employed to quantify air leakage and pinpoint specific areas of concern. Addressing lämpövuotoille contributes to a more comfortable living or working space and reduces the environmental impact associated with energy generation.
