Measurement and Description of Total Energy Use and Indoor Climate Quality in Buildings Applied to an Office Building by Field Monitoring

Studies of the energy performance of buildings have increased in recent years by real energy consumption measurements. What it is essential to clarify is that actual building energy consumptions are strictly correlated with the indoor climate quality required by the occupants: when real consumptions are examined, consider the contextual analysis of the indoor climate quality levels maintained in the spaces, and the corresponding energy demand, is essential. Both total energy use and indoor climate quality can be expressed with different levels of detail, from the entire building to a single room. For example consumptions can be assessed starting from an aggregated indicator expressed in primary energy, till the energy demand divided into single end-use. In order to make an evaluation of the total performance of a building, in this paper different levels of information for the energy analysis are examined. Methods for presenting the results, including both energy performance and indoor climate quality are proposed too. Moreover, this paper illustrates a methodological approach for the analysis of energy and indoor climate quality in buildings, conducted through long-term field monitoring applied to an office building
