Japan No1. Share, SKETCH insulated glass coating offers to apply by special price. This

special plan aims to recover the initial installation cost in 5 years. Low price energy-

saving measures and its best plan that makes it possible to reduce electricity costs.

Usually Application fee is 8,800 JPY per 1 square meter in Japan. However, it can be

applied 3,000~ 5,000JPY per 1 sqm in order to hasten the initial investment recovery

period. Support the verification and simulate energy saving measurement data, so you

can be calculated until the recovery period and subsequent profit.

Point of power consumption reductionIn Japan, the air conditioning costs is 44% of the power consumption in the office

buildings. It is the most important challenge is to reduce air conditioning costs during

peak time (10:00 AM to 4:00PM). The basic charge of electricity bills (Contract power

cost) will decide on the basis of the peak value of the largest power consumption month

on the past year. So power consumption of September (the hottest time of the summer) is

the most expensive in one year, it will be the basic charge of electricity bills.

The rate of heat coming from the window

平成23年5月資源エネルギー庁(東電管内の需要構造推計･業務部門)より

In summer, 71% of heat enters through the

window glass from the outside when the entire

building as 100%. (13% of heat from outer

wall, 9% from the roof, 2 % from the floor

etc. ...) A measure of window glass is most

important for energy-saving and power-saving

of the building.

Korean Construction Company measured the temperature at 4 rooms under the same conditions. As a result, the

room temperature was at most 3.6 ℃ lower than the non-coated room. Air conditioning cost reduction rate of the

year was 14% (28%). （※As a condition, the temperature setting of air conditioning change 1 ℃ effects 5% of the

energy-saving .Calculated at 10% in Japan）Calculate the application cost by electricity charges and labor costs in

South Korea, it has proved to be recovered in 4.9 years. South Koreas is the cheapest electricity rates in the

developed countries, it will be recovered within five years even there is winter time.

◆Singapore golf course

Result of the temperature measurement, the temperature difference of the direct heat at the window was 8 ℃

(maximum) in comparison with the uncoated glass (Low-E glass) Reduction rate of the air conditioning costs

was 20 percent, so recovery of the initial investment simulated in 2.03 years. Because there was high electricity

prices and low applicator cost. For 10 years coating guarantees, we can expect significant cost savings of 20% to

30% more than eight years is. ⇒ 2years payback period and more than eight years profit

even the air conditioner temperature set 19℃, customer requested to apply “IRUV CUT COAT H-SP" partly and

measured the temperature. Customer comments : “It became cool and possible to set the air conditioning 24 ℃.

We felt the intense heat shielding effect ". The 5% of air conditioning load reduction (about 30-50%).

Example of Saving Energy simulation

■Calculate the electricity consumption after application

・Ex）Average temperature＝ 2℃.

Consumption of Air conditioning＝ 18kW

The electricity consumption after application will be

18kW-（18kW×0.2 ）＝14.4kW

■Calculate the reduction of electricity consumption

・Ex） Daily power consumption：10h , Days of operation : 365days

Power consumption before coated[kWh]=（18kW×10h×365days）=65,700Wh

Power consumption after coated[kWh]=（14.4kW×10h×365days）=52,560Wh

Yearly reduction of power consumption =657,00Wh- 52,560Wh＝ 13,140Wh

■Calculate of energy saving cost・Ex） Electricity fee＝ 15JPY/kwh,

Application area＝ 200㎡,

Application cost＝ 200㎡×2,500JPy=500,000JPY

Yearly saving cost =13,140Wh×15JPY=197,100JPY

Payback period = 500,000JPY ÷197,100JPY ≒Recover in 2.5 years. Then if the

durability is 15years, the profit will continue 12.5 years

＝197,100JPY×12.5Years＝2,463,750JPY
