Lighting
Suitable light levels based on Australian Standard AS 1680 - 1990 Interior lighting are required within all workplaces to ensure your employees are not working in poor lighting that may cause eye strain and discomfort. The levels of lux required vary depending on the tasks being performed.

Ventilation
Ventilation refers to the movement of air and rate of fresh air input. Air movement of less than 0.1 metres per second can lead to stuffy rooms whereas above 0.2 metres per second draughts can be felt.

The Australian Standard AS 1668 Part 2 1991 Mechanical ventilation for acceptable indoor-air quality sets out the absolute minimum requirements for fresh air.

Humidity
Humidity refers to the amount of water vapour in the air. The optimum comfort range for relative humidity is 40-60 per cent. Low humidity can cause dryness of the eyes, nose and throat and may also increase the frequency of static electricity shocks.

Temperature and air conditioning
In Australia most people work comfortably at temperatures between 20 ~ 26 degree Celsius. The preferred winter temperature is usually about two degrees lower than in summer.
