Toyo Electronics Production Plant Insulation

Who: Toyo Electronics Production Plant Insulation

Where: Kofu, Japan

When: January 5th, 2013

This electronics plant insulated their exterior roof and ceiling to reduce solar heat loading, insulate for ambient temperature and reduced HVAC costs

Toyo Electronics thoroughly researched solutions for reducing energy costs at their silicon glass diode production facility in Kofu, Japan. The method selected for reducing power cost of air conditioning was radiant barrier insulation coating applied on the rooftop. 

Roof top and exterior wall application of insulation coating resulted in peak load reduction of 37% of air conditioning electricity cost. The annualized daily electric load factor reduction was 15% with a return on investment (ROI) in 5.4 years.
