Natural light in architecture is one of the most important aspects of architecture for its impact on the wellbeing of humans, energy conservation, and enriching the spaces. Till the 1940s, natural light was the only source of light in buildings. But after the discovery of electrical lighting, in a short span of twenty years all the buildings fulfilled the lighting requirements of all the occupants. Recently due to focus on energy conservation, once again natural lighting is being integrated into the buildings, and research on its impact on people is thoroughly studied.
Here are the benefits of natural light in architecture:
1. Conservation of energy | Natural light in architecture
As most of our focus of designing and architecture is largely on sustainability and conservation of energy, proper use of natural lighting can reduce the cost of energy consumption up to 40%. Natural lighting could be used for temperature control in the room, air conditioning, and replacing or reducing the requirement to large extents. Today AI is also used along with advanced sensors to control lighting in the room.
