Comparison between

using Daylight and

its substitutes

The relationship between lighting conditions and productivity has been studied for
many years.
This is because of the extent to which lighting enhances work performance and
is often used as the financial justification for the amount and quality of lighting
provided.
There are three ways whereby lighting conditions can affect work performance:

They are through changes in visibility, changes in mood and changes in photobiology.
All we need is a new concept when design a building.

1. Bulgarian State Standard (BDS-1786-84) for Daylight evaluation has been in use
   since 1984. It is a compulsory tool of designing buildings for industry particularly
   the size of windows. The process of design is hard and there is no connection with
   enthalpy and energy consumption.
