One of our greatest challenges of our time is sustainable development that emphasizes sustainable construction with emphasis on energy saving and application of renewable energy technologies in the built environment. The issue gets serious dimensions when we are in an energy crisis. Proceedings of the energy crisis we are going through periods where there is deliberate or not reducing the supply of primary energy form.
In any case, this entails an increase in production cost of conventional energy (electricity), and of course the price of natural energy resources such as oil. This directly affects the economy of a State, as the cost of manufacturing increases dragging the wholesale and retail prices. Above all, however, it contributes to an undesirable disturbance of the import / export balance energy-dependent countries such as Greece.
Which causes about 50% in Europe, buildings now accounts for 42% of final energy consumption (energy is consumed for heating the cool, lighting, cooking and other electrical uses in buildings) of emissions of carbon dioxide and 35% of all greenhouse gas emissions in the atmosphere, emissions increase the greenhouse effect and causing climate change.
At the same time, both the consumption itself and the resulting climate change have caused a new oil crisis with enormous economic consequences. Energy savings in buildings means improving the security of energy supply, reduce carbon dioxide emissions, improve comfort conditions in the home and the workplace and therefore promotes the livelihoods of many people.
Why thermal-break windows
Great source of eco power drain is the glazing and frames. It is estimated that only if replaced with double glazing, a reduction in consumption by 32% while simultaneously insulating the exterior walls, which is simple and existing buildings, the saving is 50%.
On heating a compartment, the use of an aluminum frame with thermal break, compared to the simple aluminum decreases to 1/3 and the loss of heat from the frames and can reduce up to 5.1 and heating.
In Greece it is estimated that there are over 50 million square meters of obsolete frames with single glazing, which in the near future should be replaced. If all the legacy windows replaced with new, modern technology frames, Low-E double glazing, the benefits resulting from energy savings are calculated in. EUR 500 million per year.
The Greek aluminum industry has the technology, expertise and ultimately the products which can contribute to energy savings at national level, but at the level of simple Greek household. The industry may provide expertise and products to the Greek architect and engineer, which completely cover existing as well as future planning regulations. The contribution of the sector's products can play a key role in the improvement of the national economy, not only thanks to their ability to save energy, but being a major exporter of high-tech product.
Undoubtedly aluminum is the ideal material for constructing frames. It is material that combines high mechanical strength, excellent aesthetics and those with huge life without hardly ever maintenance. Properties really envied by any product.
Several years ago, the aluminum disadvantage compared to other frames materials were thermal nevertheless not retained dissemination as the main material for making frames and panes. The problem does not exist anymore. Today may be placed aluminum profiles which provide very high levels of insulation.
