The Advantages of Passive Solar Lighting (Daylighting)TJ Purewal

What is Passive Solar Lighting?

Passive Solar Lighting, or Daylighting is the use of direct, diffused or reflected sunlight to

provide added lighting for buildings.

Daylighting can fully replace electric lights.

Advantages

of Daylighting

Saves Costs

Passive solar energy can reduce monthly energy expenses by 13.8 percent.

All heat and light generated by your passive solar system is free.

No Equipment to Buy or Maintain

Homes with passive solar systems do not require central heating or air conditioning systems. 

Passive solar systems require no maintenance, as there are no filters to change or ducts to

clean.

Fossil Fuels Conserved

Homeowners who get their power from local utility companies ultimately rely on fossil fuels for energy. Therefore, using

passive daylighting conserves fossil fuels.

Environmental Benefits

Passive solar design is a completely clean energy source. It produces no harmful

fumes, pollutants or emissions that can harm the environment.

Daylighting Techniques

Effective and Successful Daylighting is achieved through…

Positioning and sizing your windows to allow for sufficient natural light to enter

your home.

Using exterior shading to diffuse the sunlight

Solar Daylighting Windows

Solar daylighting primarily occurs through large windows. Buildings that use solar

daylighting require specific placement and spacing of windows. For example, windows

that are higher up on a wall distribute sunlight better.
