HVAC The HVAC systems for the MultiChoice City building, engineered by C3 Climate Control Consulting Engineers, have been designed and optimised to make use of Thermal Energy Storage (TES) systems. These systems reduce the connected load of the HVAC systems to approximately half that of standard chilled water systems while also provides demand side management strategies such as load shifting thereby reducing the impact during peak demand hours to the Electrical supply. The upgrade to Four-pipe Thermal storage allows the elimination of electric resistance heating, further reducing the power consumption required during the winter months. 26 Heating and Cooling is provided by means of a 4-Pipe Chiller Assist - Thermal Energy Storage (CA-TES) system, using Air cooled reversible heat-pump chillers, Christopia © thermal storage system & 4-pipe in-ceiling fan coil units.
