Solar Energy from Sustainability Perspective
⚫ Priority 1: Reduce Demand⚫ Implement Passive Design.
⚫ Priority 2: Energy Efficiency⚫ Use highly-efficient mechanical and
electrical equipment.
⚫ Priority 3: Renewable Sources⚫ Facilitation of renewable energy
installations.
Sustainability’s Pyramid of Priorities
⚫ Abu Dhabi – Estidama Building Rating System⚫ RE-6: Renewable Energy Percentage of the proposed buildings energy consumption is supplied through onsite renewable energy
⚫ Dubai – Al Saafat⚫ 504.04 On site Renewable Energy – Electrical power
generation Commissioning
UAE Sustainable Certification Schemes
For all new buildings, renewable energy must be generated on-site using solar panels, according to the following percentages of the actual electrical load of the building:a - 5% of the Bronze and Silver Sa’fa.b - 10% for Golden and Platinum Sa’fa.

Dubai Clean Energy Strategy
⚫ The Dubai Clean Energy Strategy
2050 was launched by HH Sheikh
Mohammed bin Rashid Al Maktoum,
to provide 7% of Dubai’s total power
output from clean energy by 2020. This
target will increase to 25% by 2030 and
75% by 2050.

Rashid Al Maktoum
Dubai Clean Energy Strategy 2050
Clean energy = 75% of Dubai power output
Solar Park is the first milestone
Shams Dubai Initiative: Solar energy by Dubai
citizens, businesses and industries contribution.
⚫ Launched in 2012 by HH Sheikh Mohammed bin
Rashid Al Maktoum.
⚫ The largest single-site solar park in the world.
⚫ The solar park will generate:
⚫ 1,000MW by 2020
⚫ 5,000MW by 2030
⚫ Total investments up to AED 50 billion.
⚫ Upon completion, the solar park will reduce over
6.5 million tonnes of CO2 emissions annually.

⚫ Easy steps:
⚫ After obtaining the necessary approvals, site
works are undertaken.
⚫ Once the installation is complete, the contractor
or consultant submits a notification,
⚫ DEWA then conducts a technical inspection of
the site and install the required smart meters to
complete the connection process.

⚫ A total of 1,354 photovoltaic installations on residential,
commercial and industrial buildings in Dubai have been
connected by DEWA as part of the Shams Dubai initiative.
⚫ DEWA encourages
household and building
owners to install PV
panels to generate
electricity and connect
them to DEWA's grid.
The electricity is used
on site and the surplus
is exported to DEWA's
network.
