An office building in Lyon, France has been studied. Phase Change Material (PCM) has been installed as wallboard and as latent heat thermal energy storage system coupled with the ventilation system. The main purpose of this study is to determine if the PCM system can guarantee the summer comfort of the occupants without energy-consuming cooling devices. Sensors have been set up and the collected data are monitored to study the thermal behavior of the building and the PCM. Numerical simulations complete the work to study the building behavior without PCM and to compare. The temperature charts in each office show that the comfort of the workers is acceptable in winter and in summer. Numerical results show a difference of temperature in offices due to the PCM in the partitions and in the ceilings. The temperature in the crawl space is included between 13 and 20°C all over the year, so the precooling or preheating system for the ventilation air is efficient.
