PROJECT BRIEF
EECO2 was to provide the client with principle consultancy expertise to support an Energy Assessment with their GMS manufacturing chain.
Along with the site team and the energy assessment team, EECO2 performed an energy assessment on the client site in Japan – focusing on HVAC improvements.
The client site has a real opportunity to deliver significant energy and cost savings over the next 5 years. Especially involving HVAC, as this is their largest saving opportunity. Any changes to the HVAC system must be done in a way that ensures no quality impact and so it is important to involve HVAC experts like EECO2.
