This thesis treats angle-resolved optical properties and the energy efficiency of windows. A theoretical evaluation of optical and thermal properties of windows is briefly surveyed and the energy performance of a large selection of windows, under different conditions, is examined. In particular, angle dependent optical properties are analysed.
China may be the 2nd largest emitter of greenhouse gases (GHG) on the planet. Since 68% of its primary energy is from coal, China’s average energy intensity is 7. 5 times greater than the EU and 4. 3 times greater than the
In recent years, the drive for ever increasing energy eﬃciency has intensiﬁed. The main driving forces behind this development are the increased innovation and adoption of mobile battery powered devices, increasing energy costs, environmental concerns, and strive for denser systems. The main
