The importance of thermal mass in predictive control. Case study: a zone with floor heating and a chilled beam

Anastasios Papachristou, Andreas Athienitis

Abstract: This paper presents a simulation study of predictive control strategies to reduce and shift peak load in a zone of a perimeter office with floor heating, convective cooling and various floor configurations while maintaining acceptable comfort conditions. A case study is considered where a building automation system controls the floor heating, convective cooling and shades. For the specific case study considered, the window-to-wall ratio is 75%, resulting in high solar gains. These solar gains are useful in winter but in summer they need to be reduced by controlling the shades to reduce total cooling load. The simulations results show that an exposed concrete floor (no carpet) can lead to significantly lower peak (about 40% in cooling and 45% in heating) in the auxiliary heating/cooling as compared to a carpeted floor.
