Natural lighting vs. artificial lighting
• Considerations for natural lighting:
1) Review the functional and commercial needs of the shopping malls and shop
spaces.
2) Identify opportunities for introducing more natural lighting to the existing building
to reduce reliance on artificial lighting.
3) Review the possibility of introducing skylights and windows or glass walls in
exterior walls to bring in natural light. This helps reduce energy use for lighting
and at the same time it provides a more healthy and pleasurable shopping
environment for customers.
4) Where skylights, windows and glass walls are used to bring in natural lighting,
it is important to consider
for windows and the orientation of
skylights, windows and glass walls to avoid glare and excessive solar heat gain.
5) Shading screens or fitted low-e glass can also be added to reduce glare and
excessive heat gain where necessary.
• Considerations for artificial lighting:
1) Consider the use of light coloured décor to provide a brighter interior requiring
less artificial lighting.
2) Avoid the use of high intensity lighting throughout the entire area to reduce
energy use and glare. Special areas can be provided with accent lighting to
create a theme and reduce lighting energy use.
3) Consider the use of reflective surfaces to amplify brightness and to reduce
energy use for lighting.
4) Use energy efficient light fittings. Consider the use of LED lights where possible.
