The primary reason for building comfort control is because it is occupied. However these occupants also have a big effect of the indoor climate through heat generation, Oxygen consumption and CO2 emissions. In the majority of buildings the indoor conditions are either predefined or reactive, normally using temperature sensors. Controlling a building based on occupancy allows pro-active control of a buildings Heating, Ventilation and Air Conditioning (HVAC) system instead of reacting to temperature or other sensors.The goal of the Sounds for Energy Control of Buildings (S4ECoB) project was to use a low cost microphone array in three different pilot sites with the aim of measuring occupancy and controlling the HVAC system more efficiently.
This case study focuses on the methodology behind the development of an occupancy control strategy. It discusses how agate arrival profile was developed and the performance of one of these pilot sites, Linate Airport in Milan, Italy simulated using TRNSYS. The final goal was to develop control strategies based on the occupancy information provided using the arrival profile and ultimately reduce the buildings energy consumption, whilst maintaining comfort.
