Efficient cooling is crucial to achieving energy efficiency on Dubai level and the DSCE has asked
innogy to recommend an optimal support mechanism to drive efficient cooling, specifically DC
retrofits

P3: District cooling within DSM Strategy 2030
KEY INITIATIVES
• Issuance of regulations to support
the adoption of District Cooling
penetrations
• Awareness program in support of
District Cooling adoption through
increased dialogue between
developers, District Cooling
operators and customer groups
• Desalinated water conservation
through use of TSE provided by
Dubai Municipality for District
Cooling applications

• DSCE mandated RSB to regulate and supervise the DC sector, with aim to promote more efficient methods of cooling, targeting penetration of 40% of DC by 2030
• Savings can be achieved by better chiller operating regime, smoother load profiles, better O&M practices and sub-metering of end user consumption
• Ongoing efforts on aligning the DC market end-prices for consumers with other cooling technologies in order to ensure a win-win for both providers and end-users

Significant savings can be achieved through HVAC by utilizing both technical and policy measures
Technical
Quick wins With investment
Can be addresed at zero or low
cost:
• Turn HVAC units off when there
is no cooling demand
• Optimize temperature/humidity
settings by area
• Minimize heat gain in summer
• Minimize ventilation rates
More complex areas requiring
some capital expenses:
• Preventive maintenance
• Insulation / draught-proofing /
shading
• Implementation of variable speed
drives
• Upgrade of cooling systems with
new tech
Policy
• Mandatory cooling codes with respect to
buildings/industries and minimum energy performance.
• Improving energy efficiency of existing buildings
through target setting and roadmap establishment.
• Improved energy performance of building components,
appliances and systems via introduction of star rating
for appliances.
• District cooling regulation and associated minimum
energy performance.
Government is leading by example - all government buildings are mandated to adjust temperature to 24 °C during and 27 °C after office hours.
Green procurement will be introduced to further promote implementation of „green” HVAC.

2030
Total demand: 83.6 TWh
Cooling demand: 41.2 TWh
DC savings: 3.4 TWh
DC retrofit savings: 1.5 TWh
DSM savings: 19.2 TWh
DSCE has concluded a study in governance options to ensure cooling demand is a focus for creating savings in upcoming years.
Overview of potential by 2030
14
Within the study, DSCE has identified challenges in both the cooling efficiency and the real estate market
• Perceived high cost of DC
• Low market awareness
about cooling solutions
• Retrofit teams focusing
mainly on non-DC
• Difficult access/
no corridors
• Inefficient
building design
• Over consumption
• Short term
investment horizon
• Tennant-operator-owner
dilemma
• Cooling capacity
over-design
• Existing DC over-capacity
• Inefficient chiller operation
• Usage of non-TSE water
• Low incentive to achieve
efficiency (billing agent)
Cooling Real Estate
15
A tentative roadmap has been designed and presented to main cooling market stakeholders
Y1 Y4Y3Y2 Y5
• Establish DSCE DSM Cooling Committee
• Develop and launch a DSCE Cooling Directive
• Establish a dedicated cooling agent
• Launch and manage the “Dubai Cooling Map” platform/database
• Annual stakeholder engagement and awareness campaign
• Integrate cooling across stakeholder strategies
• Review cooling regulation and licensing criteria
• Integrate holistically in the DSM Strategy review
(preferably 2018, by no later than 2019)
• Establish efficiency standards and reporting scheme for cooling
• License consultants, facility managers (O&M) and billing agents
• Launch impartial and binding complaint resolution mechanism
• Develop masterplan for long term efficient cooling in Dubai
DSCE is continuing to look into best practices and aligning with stakeholders on best way forward.
