+ | Another result from this analysis: The true heating line (the one depicting the total heat losses of the building monitored) can NOT be derived from a correlation analysis of the measured heating loads and the temperature difference (indoor minus outdoor). Such a correlation would mix up the passive solar gain influence with the heat loss influence. Instead, the correct line can be optained by finding the tangent from above to the value cloud. You might have to eliminate outliers first. This tangent has a far higher slope than the line you would get from the linear correlation coefficient.
