Quality of load measurements

Critical for the validation and use of a load model is to have access to quality load measurements.

Collection of data, qualitative verification of data by inspection and the quality assurance of collected data are important steps when using load measurements. Over the last years, automatic hourly measurements of energy consumption have become more widely available, at least for large buildings.

The hourly district heat measurements comprise for example the end-uses space heating, ventilation heating and heating of tap water, whereas the hourly electricity measurements comprised the end-uses lighting, pumps, fans and electrical appliances.

However, the accuracy of the instruments used can induce a degree of uncertainty in measurement that will propagate further into the load model
