Lighting accounts for 5% of the global CO2 emissions. Its carbon footprint has a significant impact on global warming. Also, in the transition to mainly electricity-based energy systems, lighting with 15% of the electrical energy consumption, is in strong competition with other existing or new consumers, e.g., e-mobility or heat pumps. With rising electricity prices and steadily higher directly taxed CO2 emissions also lighting costs increase significantly. Thus, to make today’s high comfort lighting installation more efficient, the consumption of electric lighting systems must be cut further, and benefits of daylight used better. And, moreover, embodied energy for electric and daylighting - i.e., façade technology - must be taken into accounted.
