varmetapskoeffisienten
Varmetapskoeffisienten, or heat loss coefficient, is a parameter used in building physics to quantify how quickly heat is lost from an enclosed space to the surrounding environment. It represents the rate of heat transfer per unit temperature difference between indoor and outdoor conditions. The quantity is typically denoted by H and has units of watts per kelvin (W/K).
It can be calculated as the sum over all envelope elements of their heat transfer performance, H
Usage: The heat loss coefficient is used in energy balance calculations to estimate heating demand, to size
Measurement and estimation: H can be determined from construction specifications by summing U_i A_i, or estimated
