Windows are the key loss factor of energy

Global trends:	Problem:
ECOlogy, green construction	Due to physical limitations, glazing can be several times less energy efficient than solid insulated walls.
Energy saving	Big part of the energy is lost to environment across the windows. Especially in regions with extremely hot or cold climates
Natural lighting	Climate change. Lack of energy in some regions, accidents and disasters
Panoramic windows	This makes it impossible to operate buildings using only alternative energy sources.
Passive House	Rising cost of utility bills

Buildings lose more than 50 percent of their energy through the windows in both cold and hot climates. Citadel allows for increased glazing and maximum use of natural light without wasting energy, which leads to reduction of heating or condition demand and СО2 emissions. Also our solution lead to a decrease in the cost of construction. This is due to the fact that the building will require less powerful installations for cooling and heating the premises. It is the lasting solutions for improved quality of life and health, unique protection from heat, cold and noise cancelling.

Improving the energy efficiency of skyscrapers without increasing construction costs

Almost all buildings in the world have glazing. Our potential clients are developers of private, commercial and public buildings. The greatest economic effect will be achieved in hot and cold climates. For example, in the USA 35 percent, in the GCC countries 70 percent of electricity is spent on air conditioning

The glazing sector has enormous potential for saving energy and living expenses.

**3 elements of Citadel glazing technology**

Mass implementation of our technology will provide to reduce energy consumption during operation of buildings several times, to reduce the amount and powerful of engineering equipment, to extend the service life of necessary engineering equipment, to significantly reduce the cost of utilities, to increase indoor microclimate for life and health. Saving energy by the secure and sustainable our energy saving glazing will to reduce greenhouse gases and emissions, to reduce air heating from the operation of engineering equipment, and using less combustibles, Also our glazing will provide comfortable living without harming the environment in remote areas with extreme low or high temperatures. We propose to make glazing several times more energy efficient. For example, our solution in the GCC region (Bahrain, UAE, Saudi Arabia, Qatar, Kuwait, Oman) can exceed the energy efficiency characteristics of local codes glazing requirements by 10 times.

The index of glassing heat transfer resistance in the GCC region varies from 0.33 (m2 K)/W and when using glasses with low-emission cotings with argon gas filling can reach 0.65 (m2 K)/W but our solution 5 - 10 times more efficient than conventional windows in GCC
