Building HVAC

While trying to reduce the usage of power consumption an innovative strategy being adopted globally is to manage the energy effectively by demand side management. The concept of demand side management is to use Phase Change Materials having a high thermal energy storage capacity which uses power during off peak hours to store the energy and release it during peak hours.

This strategy allows almost 50% of the HVAC load to be shifted to the night time/off peak hours, which translates to an overall reduction of more than 25% in the total electrical load of a building.
