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.

Dubai Clean Energy Strategy 2050HH Sheikh Mohammed bin

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.

Shams Dubai Initiative, Dubai, UAE.


⚫ 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.

Shams Dubai Initiative, Dubai, UAE.


⚫ Solar Roof features:⚫ Translucent Photovoltaic Panels. ⚫ Adequate balance of daylighting, shading and energy generation.
