lämpövuotona

Lämpövuotona refers to heat loss in Finnish. It describes the unwanted transfer of thermal energy from a warmer area to a cooler area. This phenomenon is common in buildings, where heat can escape from the interior to the exterior during colder months and enter from the exterior to the interior during warmer months. Factors influencing lämpövuotona include the insulation quality of building materials, the integrity of the building envelope (walls, roof, windows, doors), and air infiltration.

Understanding and minimizing lämpövuotona is crucial for energy efficiency and occupant comfort. Inadequate insulation leads to higher heating and cooling costs as more energy is required to maintain desired indoor temperatures. Air leaks, often found around windows, doors, and penetrations in the building envelope, are a significant contributor to heat loss. These leaks allow conditioned air to escape and unconditioned air to enter.

Methods to reduce lämpövuotona involve improving insulation levels in walls, attics, and floors, and ensuring a well-sealed building envelope. This can be achieved through proper installation of insulation materials, sealing cracks and gaps with appropriate materials like caulk or foam, and using high-performance windows and doors. Regular maintenance and inspection of a building's exterior can help identify and address areas prone to heat loss. Energy audits are often conducted to pinpoint sources of lämpövuotona and recommend specific improvements.
