THE EDITOR, Sir:
The rise in the price of oil and JPS electric rates have focused minds on the need for energy conservation.
There has also been worldwide recognition, that natural light properly used in buildings not only reduces energy use but brings other benefits as well.
Jamaica's latitude means natural light is available 365 days a year during business hours.
In schools, a detailed study done in 1999, has shown that students in classrooms with the largest window area (natural light) graded 8-26 per cent better on tests (in all subjects) than those in classrooms with the least window area.
In retail, the same studies have shown that the introduction of natural lighting increases sales by 31-49 per cent. Wal-Mart proved this in experiments in its stores.
Natural light increases productivity and by reducing the heat generated by light fixtures, reduces the amount of air-conditioning required.
The use of natural light has to be carefully considered to avoid heat and glare but these problems can be overcome by proper placement and shading.
Reducing energy use and increasing productivity and test scores is surely a classic win-win situation.
