For Heat Cut in the summer /For prevent to escape Heat in the winterEnergy Saving measures for Window glass

The "Paris Agreement" was established at COP 21 andit was a historical agreement for international climate change countermeasures.
COP 21 (Participating Country 196) of the United Nations Framework Convention on Climate Change concluded by delegates fromeach country held in Paris, France from 20 th November 2015 will be held on December 12, 2020 local time We have officiallyadopted the international framework for global warming countermeasures "Paris Agreement". Like the Kyoto Protocol, this Paris
Agreement was agreed as a strong agreement with legally binding power. Towards "to keep the world's average temperature riseto less than 2 degrees" as the overall goal, in the second half of the century worldwide, the direction to substantially reducegreenhouse gas emissions from human activities to zero It launched. For that purpose, all countries were obliged to makeemission reduction targets and submit it, and it was also obliged to take domestic measures to achieve them. This Paris
Agreement means that the convention to decide the future direction of the world economy has been decided by a legally binding
international agreement. We decided to aim for a low carbon society and a decarbonized society all over the world. In otherwords, from now on politics, business and local governments all mean that "carbon emissions are not good.

Furthermore, in 2015, the United Nations adopted the SDGs as goals for the environment, economy, and societyof the entire international community, including developed countries, toward 2030.
Although adopted by the United Nations, the SDGs are already becoming the "common language" in the business world.
Efforts are being made by the Japan Business Federation, industry groups, regional banks, and even individual companies toachieve these goals.
In particular, large companies that are expanding their businesses around the world are beginning to reassess their entire value
chain, which is expected to have an impact on related suppliers.
With the spread of SDGs, it is becoming necessary to respond to SDGs as the needs of the market and the needs of business
partners. In fact, we are entering an era where we can see not only profits but also whether we are working on the SDGs as acondition of investment.
In this way, global warming is a serious problem that immediate measures and improvement on a global scale are urgent.
Based on this world situation,
In order to promote global warming countermeasures, at Sketch Co., Ltd., with the aim of "Energy Saving Decarbonization
Society Starting with a Window - Prevention of Global Warming" as a flag, the window glass (90% of domestic existingbuildings) which is not an energy saving specification, We propose thermal insulation renovation of window glasswith coating solution.

The window glass with the most heat transfer
It is not an exaggeration to say that summer heat and coldness in winter depend on the window.
The influence of exterior walls and roofs that are in contact with the outside air is surprisingly small,and most of the heat comes in and out of the windows.
73% of the solar heat comes into the room from the window in the summer, and 58% of the heating heatescapes from the window in the winter , assuming the whole building as 100%. In other words, in building ofenergy saving measures , heat shielding against window glass is the most effective.

The biggest point is to reduce the work of air conditioning"Air conditioning cost reduction measures"from 10 am to 4pm in the daytime is top priority

It is well-known that the proportion of air-conditioning equipment occupied in power consumption is large.
How to efficiently use air conditioning equipment that accounts for this large proportion will be the most important pointof energy conservation.
So, where and how can we improve it? For that, we must pay attention to windows where heat come in and out the most.

Method of low carbon society
From the entry into force of the Kyoto Protocol to the present, various energy-saving technologies have been developed, commercialized and put
into practical use in the construction and construction fields.
Among them, it has been clarified that window glass measures are the most advantageous in terms of the relationship between the introduction cost
and the CO2 reduction effect.

IRUV cut coat can be applied with a roller, as a heat shield in summer, UV protection, and heat escape fromheating heat in winter. In addition, it is very economical because it is more than twice as durable as a thermal
barrier film. It is an energy-saving product that does not require large-scale application.

Renovation of the window
Shields sunlight and ultraviolet rays in summer
and suppresses direct heat from the window by
about 8-15 ° C. In addition, the warmth thatfeels comfortable in winter and the outflow ofheating energy are suppressed, and the indoor
warming effect is enhanced.

Data collection / test booth
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 tobe 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.

Summer is hot and no one wants to enter the smoking room. Even if the air conditioner is set to 19 ° C every year,
it becomes hot air. Although a film was pasted, it was installed 10 years before and no effect.

Until now, even if the air conditioner setting was 19 ° C, it was too
hot to enter the room. However, after application, even if the air
conditioner setting was raised to 24 ° C, it became cool, and I felt astrong heat shielding effect.
＊ The air conditioning load is reduced by 5 ° C (energy saving about 30-50%) because it is comfortableeven at the air conditioning set temperature of 19 ° C ➡ 24 ° C.

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 highelectricity prices and low applicator cost. For 10 years coating guarantees, we can expect significant costsavings of 20% to 30% more than eight years is. ⇒ 2years payback period and more than eight years profit

Energy Saving for School
As a result of application at an elementary school in Vancouver, Canada and comparison with the air conditioning costs from 2009
to 2011, an average 16% reduction in air conditioning costs were demonstrated. Converting 16% into monetary amounts will
reduce air conditioning costs by 5,472 Canadian dollars (approximately 474,200 yen) annually, so application costs can beamortized and recovered within 1.97 = 2 years. (8 years will be profitable due to durability over 10 years)

50% suppression of Dew Condensation in WinterCondensation means that in the winter, moisture-containing air is cooled on the window glass and becomes water
droplets. When coated, the glass surface absorbs heat, warming the glass surface and slowing down condensation. In
addition, since the water retention of the coating surface itself is high, the time it takes for the water to drip is asfollows: uncoated glass = 30 minutes, coated glass = 104 minutes.
