Austria is widely recognized for having the best industrially manufactured windows in professional circles. This reputation has been further solidified by a research project titled “Cool Windows” conducted by Wood Research Austria and the Technical University of Graz. The study aimed to find a comprehensive solution to reduce energy requirements for cooling and heating living spaces while maximizing daylight. The findings showed that, with proper planning, “cool windows” could reduce cooling energy by up to 50% and heating energy by up to 30% compared to traditional windows. Additionally, these windows can help lower room temperatures by up to six degrees Celsius on hot days without the need for additional cooling.
Unlike in the past, windows are now seen as more than just insulators. They are an integral part of creating a pleasant living environment year-round. Modern windows not only provide thermal insulation but also act as a source of light, fresh air, and energy while offering protection against environmental factors like storms, heavy rain, hail, and noise. The selection of different types of glass and shading options depends on the direction of the façade where the windows are located.
Modern windows feature advanced technology that allows for automatic control of the room climate. Smart sensors can open and close windows, adjust shading, protect privacy, and even monitor air quality. With programmable presence simulations, homeowners can enhance security by controlling lighting and reporting burglary attempts in real-time. Gaulhofer believes that smart systems for controlling living environments will soon become standard in residential construction.
The replacement of windows as part of thermal building renovations is being promoted across Europe as a simple and effective way to reduce energy consumption and improve living quality. Modern windows offer higher energy efficiency, improved burglary protection, sophisticated shading systems, and smart control options. These windows also meet changing architectural demands for various shapes, colors
