SunSmart – POE
Thermochromic POE Films for Smart Windows
The energy demand of buildings is significantly influenced by windows. Windows often represent the most vulnerable part of the building envelope in terms of heat loss from radiators and have the highest interaction with sunlight and solar heat. Therefore, depending on the number of windows in a building’s facade, they are usually responsible for 30% – 40% of the total energy loss. Energy-efficient windows typically focus on reducing heat loss from radiators through improved insulation or reducing cooling demand by blocking solar heat. As these two functionalities are conflicting, current energy-efficient glazing systems are only optimized for either warm or cold climates.
To address this issue, we are developing an energy-efficient laminated window optimized for intermediate climates within the SunSmart POE (polyolefin) project, where heating in winter is as important as cooling in summer.
Our innovative heat-regulating films optimize the use of sunlight and solar heat in buildings. The thermochromic films for ‘smart windows’ enable the utilization of solar heat for heating during winter.
The laminated window being developed in the SunSmart POE project will be a fusion of advanced insulation materials and innovative heat-regulating films. This will allow the window to deliver optimal performance in areas with intermediate climates, where the need for both heating and cooling is equally significant throughout the year.
In addition to reducing energy loss and improving the thermal performance of buildings, the SunSmart POE window will also contribute to reducing reliance on artificial heating and cooling systems. By intelligently utilizing natural resources such as solar heat, buildings can become more energy-efficient and reduce their ecological footprint.
In conclusion, the SunSmart POE project aims to develop an energy-efficient laminated window specifically optimized for intermediate climates. Through the use of innovative heat-regulating films and advanced insulation materials, this window will be capable of harnessing solar heat for winter heating and blocking excessive heat during summer. With this technology, we strive for more energy-efficient buildings and reduced dependence on artificial heating and cooling systems, while minimizing our environmental impact.
