The ideal office temperature for best concentration is about 21 degrees Celsius. Too low and your concentration drops, too high and you become too relaxed and less alert.
The maximum and minimum temperature can be influenced by your gender and personal preference, but for optimum performance, this is considered the magic number. Window blinds can really help too.
Luxaflex® Duette® Shades can reduce the staggering 50% of heat lost through windows, even with double glazing. The intelligent design creates an insulating layer at your window to keep you cooler in summer and warmer in winter. Another smart feature is that you can combine light filtering and room darkening fabrics in one shade. Great for multi purpose office / bedrooms.
