It was revealed that on average, the shopping malls surveyed use 511 kWh per square metre, per annum, consume 10.86 litres of water and generate 520 grammes of waste per visitor.
“511 kWh is enough energy to run a fridge-freezer continuously for 365 days,” added Oberlin.
Seven shopping malls in Dubai took part in the project by submitting data about their consumption figures and general characteristics of their buildings. Other variables had to be taken into consideration, for example, amount of outdoor space, air conditioning by type and distribution, and the percentage of leasable and common area, which varied between 15% and 56%.
Farnek Director of Consultancy, Sandrine Le Biavant, who was responsible for launching and monitoring the benchmarking project, said: “Metering systems are integral for aligning industry KPI’s, promoting sustainable best practice and providing an accurate monitoring system that will ultimately create better efficiencies. We continue to drive the industry forward, so it is encouraging to see a number of malls taking the initiative from an energy management perspective.”
To evaluate energy performance, the internationally recognised metric Energy Use Intensity (EUI) per unit of gross floor area was adopted. Results varied from a low of 320 to a high of 627 kWh per square metre.
“A low performing mall uses almost twice as much energy as a better performing mall, underscoring the importance of a comprehensive energy management plan and the savings it can make,” added Oberlin.
To calculate water usage, Water Use Intensity (WUI) per visitor was used with the worst performing mall consuming 14.51 litres and the best just 7.3 litres per visitor.
“The results show that the potential water savings for some of the higher consumers is significant,” said Oberlin.
In terms of waste management, two key performance indicators (KPI) were used, a waste generation ratio per visitor and a diversion rate, which identified the amount of waste diverted from landfill, in other words reused or recycled. The results varied between 250 grammes and 1.08 kilos per visitor, with malls on average diverting 23% of their waste from landfill.
“A poor waste performing shopping centre generates over four times as much waste as the best performing mall and given the increased Dubai landfill rates that will come into force on 18th May, savings here could be considerable.
“Moving forward with the Mall Stakeholders Group, we aim to get more malls involved in this initiative, not just in Dubai but from other Emirates too. We will also input more up-to-date data and look to broaden the range of our retail benchmarking capability,” explained Oberlin.
