lämpöhaaskua

Lämpöhaaskua, often translated as heat leakage or thermal leakage, refers to the unintended or excessive loss of heat from a building or system to its surroundings. This phenomenon is a significant factor in energy efficiency and building performance. In buildings, lämpöhaaskua can occur through various pathways, including conduction, convection, and radiation. Conduction happens when heat passes through building materials like walls, windows, and roofs. Convection involves the movement of heated air, often escaping through cracks and gaps in the building envelope. Radiation is the transfer of heat through electromagnetic waves, which can be lost through uninsulated surfaces.

Identifying and mitigating lämpöhaaskua is crucial for reducing heating costs and improving indoor comfort. Common areas where heat leakage is prevalent include poorly insulated attics and basements, single-pane windows, and gaps around doors and electrical outlets. Thermal imaging cameras are often used to detect these areas of heat loss, making them visible as cooler spots on the building's exterior or warmer spots on the interior.

Strategies to reduce lämpöhaaskua include improving insulation levels in walls, roofs, and floors, upgrading to more energy-efficient windows and doors, and sealing air leaks with appropriate materials like caulking and weatherstripping. Proper ventilation systems can also help manage heat exchange within a building, preventing excessive heat loss while maintaining air quality. Addressing lämpöhaaskua contributes directly to a more sustainable and cost-effective use of energy.
