An approach that uses passive solar heating instead of electricity for businesses and homes is known as A. Daylighting.
<h3>What is daylighting?</h3>
This is the illumination of buildings with natural light through the practice of placing reflective surfaces so that sunlight can provide effective internal lighting.
Solar heating is the use of sunlight to heat water or air in the buildings using radiant light and heat which is harnessed using a range of technology such as solar power to generate electricity.
Hence, we can see that neither weatherizing, green roofing nor cool roofing is the answer because they do not deal with providing passive solar heating, but daylighting uses passive solar heating.
Therefore, the correct answer is option A.
