The most efficient energy is the one that is not used.
In service buildings such as offices, schools and health services, energy consumption in artificial lighting means more than 30% of its total energy consumption.
The increase in electrical rates and the need to reduce electric consumption because of environmental reasons require using artificial light alternatives. As we know, the solution is taking profit of sunlight, a free and inexhaustible light source.
That’s why the use of daylighting systems has become a clue factor in architectural design. Until recently, everything depended on the optimal building orientation, the atria, and the façade light entrances like windows and skylights, which we might call traditional daylighting systems.
But the performance of this traditional systems is insufficient, we need new efficient daylighting systems, like sun pipes and skylight reflectors. Well-designed daylighting projects that incorporate efficient daylighting systems allow savings achieving of up to 40 % in building consumption.
