Tadmur HQ Energy City Lusail CWQ Awards nomination
Innovation Unlimited explains why it nominated Tadmur HQ, Energy City Lusail and why it feels the project made the shortlist of the awards
With a little more than a week before the Construction Week Qatar Awards take place on 9 September, CWQ asked Innovations Unlimited about one of their two nominations for Sustainable Project of the Year at the Construction Week Qatar Awards.
Diala Khairallah, marketing manager, Innovations Unlimited, Green Division explains why Tadmur HQ, Energy City Lusail was nominated.
"Innovations Unlimited ME is the renewable energy system integrator appointed to engineer, install and operate a 55KWp roof-mounted photovoltaic system at Tadmur Head Quarters," she explains.
Khairallah points out that the building was the first “to be constructed in Energy City Lusail, and stands as the first green building of the developing city. Utilising multiple sustainable technologies to achieve a LEED Gold certification, Tadmur HQ has pioneered the integration of renewable energy in the city that is planned as the hub of the wider energy industry.”
There were numerous considerations to be taken into account, including critical design factors such as location/insolation level, orientation and limiting factors like shading, roof construction and usable roof space.
“The system was value-engineered for a quick, easy installation that generates clean, free electricity and offsets peak costs,” she points out.
“Using 250 south-facing PV modules, this system is laid out in two PV arrays of 380m² each, providing a solar PV power source delivering a total peak output of 55 kWp and an estimated annual energy yield of 1,406 kWh/kWp.
“The hybrid system includes a battery storage component that ensures continuous electric load feeding into the building day and night,” Khairallah continues and explains that what renders the installation unique is a mounting system that has been set against standing seam metal sheets’ “the same kind used for the stone cladding of the building itself.
"This method of mounting provides an extra layer of insulation for the roof, while allowing for a least intrusive mounting structure”.
The ultimate result is a flat installation that resembles a building integrated photovoltaic installation, “using however, the more efficient traditional PV modules”, she adds.
The system sits flat in the parapet, blending in with the roofline in an inconspicuous manner preserving the striking architecture of the building and complementing the overall environmentally sensitive design strategies of Tadmur HQ building.
“Moreover, the building represents one of the very early solar installations in a country that is just scratching the surface of its renewable energy potential,” Khairallah concludes.
