Analysis of the impact of indoor climate conditions on office building energy modeling results

Abstract

The study is conducted using the dynamic energy modeling program IDA ICE. The model of the office building under investigation is created based on real data. The building’s energy consumption is normalized, and the model is calibrated. Air measurements have shown that the building is experiencing dry indoor air – this is the biggest microclimate issue of the building under investigation. The primary simulation has shown that the model results correlate with the conducted measurements. To address the low relative humidity issue, the ventilation system’s air supply mode is changed from constant air volume to variable air volume with humidity control. By changing the input data, the annual energy demand decreased by 6 MWh, and the percentage of dissatisfied people (PPD) also decreased by 3%.
