Their system consists of smart controllers and proper insulation and can potentially reduce the HVAC power consumption by up to 10%.

 "

According to the partners participating in the project, it should be possible to reduce energy consumption for HVAC systems by at least 10%. The objective is to develop a simulation model for the optimization of a tram’s climate control systems.
