It is therefore clear that forIt is therefore clear that for developing nations such as

Mauritius, sustainabilitysustainabilitymust be a priority.


• Minimise heat gains - design to shade all year round

• Consider building orientation• Consider building orientation, form, and thermal mass

• Specify a high-performanceSpecify a high performance building envelope

• Maximize passive heating, cooling, ventilation, and daylighting

• Install efficient systems to meet remaining loads

• Ensure individual energy-using devices are as efficient as possible

• Ensure the systems and devices are properly commissioned
