Natural lighting and unobstructed viewing are two of the fundamental requirements of glass facades. Approximately 50% of Solar Heat energy arrives at the earth’s surface as visible light, so careful consideration of this property is required to optimize building design to minimize energy consumption while adhering to the
fundamental requirements. It is of particular importance to consider minimizing indoor visible light reflectance for night time occupation, as illuminated building interiors often produce undesirable mirror effects on window glass and can ruin spectacular external night views. The correct glass and coating combination selection can
minimize this issue and also deal with the unwanted solar energy during daylight hours.
