70-80% of energy consumption in a villa is used to cool the spaces. This depends on both, outside air temperature and on occupant usage pattern. 50-60% of water consumption is due to landscaping water requirement. Families living in independent houses in Dubai are paying an average AED 24,000 per year.
The rising DEWA tariff is often a source of concern among independent house owners who want to reduce their water and electricity bills. We did a study of a typical Villa to analyse daily routines, air conditioning temperature set points, villa design, air conditioning system design and other factors. Feasibility was analysed to finally derive simple and cost-effective solutions to bring down energy consumption.
What Can be Achieved?
Savings of AED 5,000-10,000 annually is possible with a small investment. Some of the simple strategies include:
- Simple behavioral changes
- Segregating of Spaces for better air-conditioning efficiency
- Landscaping water use reduction
- Replacing energy intensive lamps to energy efficient lighting
- Efficient water fixtures
