Abstract
A method determining heat loss coefficient K of a premises, includes: in unoccupied premises, performing a campaign of measurements of at least one temperature inside the premises Tat closely-spaced time intervals over at least two successive time periods Dcorresponding to distinct heating powers Pof the premises; determining temperature of outside air Tat the same closely-spaced times; for each time period D, on the basis of evolution T(t) of a quantity Tas a function of time, selecting a time interval Δtfor which the evolution T(t) is substantially linear, then determining the slope αof the tangent to the evolution T(t) over this time interval Δt, and deducing the value of the heat loss coefficient K of the premises on the basis of the slopes α.
