Industrial case studie Actual proof of power saving effect Example works and power saving effect Model 1 Automobile parts factory (Saitama factory) Model 2 Packing distribution warehouse (Kawasaki factory) Latest info: Supermarket pref. 2012. Electricity usage redused after using Adgreencoat. 2010 before using AGC 7 July 161,815Kwh (Max demand 317Kwh) 8 Aug 169,328Kwh (Max demand 329Kwh) 2011 after using AGC 7 July 133,195Kwh (Max demand 257Kwh) 19% reduced 8 Aug 130,763Kwh (Max demand 254Kwh) 23% reduced * 11 more stores will use Adgreencoat because of the good reputation of power saving effects by heat shield coating.
> Case 1 Auto parts factory (Saitama factory) Industry Before coating measured on 3 may After coating measured on 2 June 5/3 測定 6/2 測定 Before coating 45 C After coating 32 C Load on air conditioner The height to the roof Before coating/affect of radiant heat There were no heat insulators under the roof. The galvalume steel sheets were exposed. As the ceiling materials were directly installed to the roof, the radiant heat of the roof was greatly affecting the indoor temperature. Heat pool has been solved by reflecting about 90% of the heat-source from the sun and showing the function of heat-exhaustion /radiation. inside the factory was 7,2m on the ground floor, 5,6m on the 1st floor. By the effect of the outside temperature and the radiant heat, the heavy load for the air conditioner was a big problem. Indoor temperature reduced, contributing to cost-cut of electricity charges. After coating
