The establishment of the Center reflects the interest of the state in rationalizing and upgrading energy efficiency in KSA 2010 2012 2013 – 2018 28_85 30_85 31_85 21_85 Established through Council of Ministers decision Inter-agency effort to launch the Saudi Energy Efficiency Program (SEEP), with guiding principles, a clear strategy and strong governance
Program covered mainly demand management for the following sectors:
Transportation
Industry
Buildings Full-fledged program with 12 teams ~80 initiatives at different stages (feasibility, design, execution) SEEP Now New mandate for SEEC has been approved in 2018

Implementing EE standards on equipment resulted in notable improvements for the affected products Increased T1 EER 57% for split-type ACs and 36% for window-type from 2012 to 2018
Only increased T3 EER for split-type ACs by 35% and for window types by 14% since 2012 due to ambient temperature limitations on usable gases Small ac 24_85 7_85<br>

Improvements in T3 EER for small ACs were limited in comparison to T1 Increased T1 EER 57% for split-type ACs and 36% for window-type from 2012 to 2018
Only increased T3 EER for split-type ACs by 35% and for window types by 14% since 2012 due to ambient temperature limitations on usable gases Small ac 7_85 Any alternative gases considered should allow raising the T3 EER limitations<br>

How High Ambient Temperature conditions affect the heat load and the system efficiency Saudi Arabia Climate Data by City zone 1 represent 70-80% of total KSA population.
(HAT) could reach around 50°C in summer, this will lead to:
Up to 12 daily Operating hours for ACs.
+ 30% decrease in AC efficiency. Saudi Arabia Climate Zones Zone 1 is extremely hot with CDD 18.3 C greater than 5,000;
Zone 2 is very hot with CDD 18.3 C greater than 3,000;
Zone 3 is hot for the remaining cities.<br>

Going beyond equipment, SEEP has initiatives targeting energy efficient building design Introduced standards for 15 insulation types used in the Kingdom
Began enforcing insulation requirements on residential buildings in 2015 Insulation materials Saudi Building code Energy use intensity (EUI) Updated the Saudi Building Code concerning energy efficiency in buildings (SBC-601) to mandate use of standard-compliant insulation
Also added requirements for ventilation and use of energy efficient equipment Currently designing a program to rate buildings based on their EUI (energy consumption per square meter)
One aim of the program is to make energy efficient design more attractive to design offices 5_85 11_85 12_85<br>

To ensure the standards are properly followed, SEEC cooperates with relevant entities to enforce them 9_85 11_84 17_85 18_85 Enforcement follows three stages 1 2 3 Announcement workshops are held for all standards with manufacturers, importers, laboratories
Dates and deadlines for the enforcement plan are declared Announcement workshop Monitoring and enforcement tours Market Sampling Within a year from the announcement of a standard, factory visits and customs ports monitoring for non-compliant products begin
Within the following year, visits for markets and warehouses to check efficiency labels begin Samples are purchased randomly from retailers across the kingdom
The compliance statistics obtained from this plan serve to judge the effectiveness of the previous stages
Stages 2 and 3 are ongoing<br>

CAGR SEEC’s efforts in energy efficiency helped slow the growth of electricity demand and consumption ~5% 3.5% ~7% 3.7%<br>
28
But these results can be severely impacted by changes to the allowed cooling gases If the alternatives proposed for the Montreal Protocol do not achieve the efficiency, safety, and the high ambient temperature requirements for KSA, we may lose the results of our efforts so far<br>
