Yes! a daylit room requires less artificial lighting throughout the year.

  • For cooler seasons: during cooler seasons, good daylight access goes hand in hand with more solar heat gain in a room. This reduces artificial heating demand and saves on energy.
  • For hotter seasons: during hotter seasons, good daylight access can eliminate the need for artificial lighting. This not only saves on electricity used by lighting fixtures but also reduces the cooling demand imposed by the heat gain from lighting fixtures.
