Sensitivity analysis of the proposed method for determining dynamic heat flux lost through the building envelope

Utilization of Multiple Short Heat Consumption Measurement Method for Diagnostics of Heat Source of Existing Building: Part 1: Theoretical Basis of the Method

“…In [4] there is included a procedure for determining the required heat source power based on a long-term measurement that includes determining seasonal heat consumption and determining the heat gains and loss of the temperature balance of the building. The problem of determining the heat demand of buildings and its accuracy, also determining the demand (consumption) or the required power of the heat source taking into account the measurements are, among others, reported in works [6,7,15,[18][19][20][21][22][23][24][25][26][27][28]. This paper presents the calculation of the heat demand for the central heating installation based on short in-situ measurements in the considered building.…”

“…This paper presents the calculation of the heat demand for the central heating installation based on short in-situ measurements in the considered building. The works [8][9][10][11][12][13][14][22][23][24][25][26][27] present the idea of a proposed method based on defining the loss coefficient by the transmission H T of the building external envelope elements and the heat loss coefficient for ventilation H V together with the average ventilation change coefficient of heat loss H b and the average daily heat gain flux from people and appliances in the building ( Z,oc + Z,eq ). This method uses, among others, multiple short in-situ measurement of daily heat consumption in a building.…”
