“…Carbon dioxide emissions from fossil fuels like coal, oil, and natural gas play a significant role in the buildup of heat-trapping gases in the atmosphere and the consequent global warming. By shifting to renewable energy, such as solar [4], wind [5], hydro [6], and geothermal [7], carbon emissions can be significantly reduced, and the adverse effects of climate change can be mitigated. Another method that leads to the reduction in fossil fuel use is the adoption of waste-heat recovery techniques [8,9], which can improve the efficiency of existing systems and decrease energy consumption.…”

Daylight can contribute to substantial reductions in the energy consumed by artificial lighting applications. However, issues such as visual comfort, illumination intensity, and availability represent major issues when daylight is relied upon to illuminate buildings. There are many technologies that are used to control received sunlight and minimize its side effects. The placement of solar film sheets on window glass is a common and popular method utilized in many buildings to minimize electric lighting energy consumption without causing undue visual discomfort to occupants. To examine the practicality of this application and its effect on room lighting, a modern office was selected in which to conduct this field study. Two measures were used to evaluate this technique: firstly, field measurements and their comparison to the specified standard illumination levels; and secondly, a short-form questionnaire survey conducted to obtain occupants’ opinions of the office lighting. Actual measurements were conducted in the selected office spaces, with and without applying solar control film coating on the window glass. Indoor luminance levels and lighting comfort were systematically recorded and analyzed. The findings of this study show that using a solar film with a visible light transmittance of 50% can achieve savings in energy consumption of up to 33% if utilized as part of an integrated lighting system.
