| Abstract |
Daylighting is an interdisciplinary field between building physics and lighting technology and implements improved protection against overheating by means of novel mirror optics developed, while at the same time providing daylight, thus enabling total energy savings of glazed buildings of up to 30 %. As part of the Green Deal, the EU Commission is initiating a directive on the energy performance of buildings (EPBD), which is part of a comprehensive legislative package with the ambitious goal of defining zero-emission buildings and thus driving forward the reduction of CO2 emissions in Europe. Daylight guiding technology, which enables solar gains in winter, prevents overheating in summer and enables daylight autonomy all year round, can play a very important role in the implementation of these ambitious goals. In this essay a new daylight guiding technology will be presented, with which a total solar energy transmittance gtot of 0.05 can be realised even in open and transparent slat positions with daylight input by means of internal blinds. |
