Methodology:

The General Authority for Statistics uses a unified working methodology that is consistent with the nature of each statistical product in all of its statistical work. As a result, it is dependent on the Manual of Statistical Proceedings in accordance with the international organizations' established working procedures. The statistical product has eight basic phases, plus a ninth phase known as "Comprehensive Management," as shown in the following illustrations and explanations 

The first three phases (Scope, Design and Organization) are cooperative ones; conducted by GASTAT jointly with the developmental bodies benefiting from its data. Likewise, the fourth phase (Data Collection) is a cooperative stage conducted by the Authority jointly with the statistical population (households or establishments) to get the data and information. The following three phases (Tabulation, Revision and Publication) are purely statistical ones, undertaken by the Authority. Then, the eighth phase (Assessment) is conducted jointly with the beneficiaries. ‘Management’ is an organizational and managerial phase running throughout all previous phases. Those phases have been applied to the Energy Efficiency Statistics Publication as follows: 

First Phase: Scope: 

It is the starting point for the production of the Energy Efficiency Statistics Publication, and is and is the initial step of collaboration between the General Authority for Statistics and its partners from government agencies and beneficiaries, represented in (Ministry of Energy, Water and Electricity Regulatory Authority, King Abdullah City for Atomic and Renewable Energy, SAMA, and research centers in universities, in addition to regional and international organizations represented in: GCC Statistical Centre and the International Energy Agency (IEA) of the results of energy efficiency statistics. These entities have been approached with these entities with the aim of improving data access to them, understanding their needs and identifying their requirements, and taking into account the prospective of those entities to ensure the achievement of all the objectives of energy efficiency statistics, which are summarized as follows:

• Improving energy production efficiency.
• Improve energy consumption efficiency.
• Raising energy efficiency awareness among beneficiaries.
• Create a database that can be used as a reliable basis for energy efficiency statistics to interested and specialized persons.
• Measuring the extent to which one of the most important goals of the vision is achieved by reaching optimal efficiency that increases and improves energy systems in the Kingdom of Saudi Arabia.

Second Phase: Design:

It is during this phase that a complete design for the statistical product is set forth. During this phase, the data collection method and tools are identified. The beneficiaries are engaged in all these processes, and their feedback is taken into account, so that the product would live up to their expectations.

Key outputs of this phase are: 

1. Statistics Sources: 

The Energy Efficiency Statistics Publication relies in its data on the data of the administrative records of the (Ministry of Energy, Saudi Energy Efficiency Center) as the main source of data, in order to obtain comprehensive data related to energy efficiency statistics, the most important of which are (the amount of production and consumption of crude oil, the amount of electricity consumption and the number of subscribers) so that GAZTAT calculates its indicators and issues them in this Publication. 

2. Terms and concepts associated with the Energy Efficiency Statistics Publication:

• Energy Efficiency: The amount of energy required in the production or operation of the energy component to provide a certain level of service with reduced amounts of energy input.
• Primary Energy Savings: Direct savings resulting from an improvement in energy efficiency.
• Energy Consumption Intensity: The amount of primary energy consumption against GDP, which is measured in barrels of oil equivalent per million riyals.

3. Indicators: 

Some of the most prominent indicators in the Energy Efficiency Statistics Publication are:

4. Index calculation method:

5. Adopted statistical classifications:

Classification of data and information allows for placing them into meaningful categories to produce useful statistics, considering that data collection requires precise and methodological arrangement in accordance with their common features so that the statistics can be reliable and comparable. The Energy Efficiency Statistics Publication is subject to international standards in terms of collecting and classifying its data as it uses the following classification:

Standard International Energy Product Classification (SIEC):

It is a classification that ranks energy products according to a statistical classification. The main purpose of SIEC is to serve as a basis for developing or revising national classification schemes for energy products so as to make them compatible with international standards and, consequently, to ensure significantly improved cross-country comparability of energy data.

SIEC is intended to be a multipurpose classification, meaning that individual SIEC products and aggregates are defined to be suitable for the production of energy statistics under different country circumstances and are relevant for the presentation and analysis of energy data in various policy and analytical contexts.

6. Coverage:

Spatial Coverage:

The Energy Efficiency Indicators Publication covers energy efficiency data at the level of the Kingdom of Saudi Arabia, according to data available from its official sources.

Temporal Coverage:

The data of the Energy Statistics Publication data in this version are in time series spanning between 2017-2021.

Third Phase: Organization:

It is the final preparation phase. In this phase, the required workflow procedures are established for preparing the Energy Efficiency Statistics Publication, starting with the next “Collection Phase” and ending with the “Assessment Phase”, and the organization and grouping of those procedures. The optimal sequence of those procedures is chosen to arrive to a methodology that achieves the objectives of the Energy Efficiency Statistics Publication. Those procedures were also described and documented to facilitate any updates in future iterations. The statistical workflow procedures were tested and examined to ensure their compliance with the requirements of preparing the Energy Efficiency Statistics Publication in its final form, approve the procedures of statistical workflow, and develop a roadmap for implementation.

Fourth Phase: Collection:

GASTAT has collaborated with the relevant government bodies to obtain data on Energy Efficiency Statistics Publication from administrative records available at those bodies via formal communication to the data owners. The data is sent via e-mail and various means of transfer. The data is then uploaded and maintained on GASTAT databases in order to prepare for inspection and review in accordance with scientific statistical approach and recognized quality standards. The data owner is referred to if any observations are detected.

Fifth Phase: Tabulation:

During this phase, the Department of Energy Statistics specialists performed data processing and analysis based on the following procedures:

• Sorting and arranging data in sequence or in different sets or categories.
• Summarizing detailed data into key points or data.
• Combining many data segments and ensuring their interconnection.
• Processing missing or incomplete data.
• Processing illogical data.
• Converting data into statistically significant data.
• Organizing, presenting, and interpreting data.

Data are presented in proper tables so that they may be simply summarised, understood, comprehended, and extracted, as well as compared to other data and statistical significances. Furthermore, such data may be conveniently accessed in the form of tables.

Sixth Phase: Revision:

First: Data Outputs Validation: 

Following the processing and verification of the data obtained in the Fourth Phase, GASTAT performed calculations and result extraction, uploaded the outputs, and stored them on the database. Final audits were performed by Department of Energy Statistics specialists utilising contemporary and software techniques suited for review and audit purposes. 

Second: Dealing with Confidential Data:

According to Royal Decree No. 23 dated 07/12/1397, data must always be kept confidential, and must be used by GASTAT for statistical purposes only. Therefore, the data are protected in the data servers of GASTAT.

Seventh Phase: Publication:

First: Preparing and Processing Results Designed for Publication: 

In this phase, GASTAT coordinated, organized and reviewed the data results of the Publication. Next, it prepared tables and charts of data and indicators, and added the metadata and methodology in both English and Arabic. 

Second: Preparing Media Materials and Announcing the Publication Date: 

GASTAT already announced the Publication date on its official website at the beginning of the year. In this phase, GASTAT prepares media materials to announce the Publication release on various platforms, including social media. GASTAT then releases the Publication on the defined date first on its website using different formats, such as open data in Excel files,   

to ensure easy dissemination and access for all clients and anyone interested in energy statistics. The Publication is also uploaded to the website’s statistics library.  

Third: Communicating with Clientsand Providing them with the Publication:

Eighth Phase: Assessment:

After the Publication is released and received by all GASTAT’s clients, the clients are contacted again in this phase which allows for evaluating the whole statistical process that was carried out, with the aim of constant improvement to obtain high-quality data. Proposed improvements may include methodologies, processes, systems, statisticians’ skills and statistical frameworks. This phase is done in collaboration with data users and GASTAT’s clients through a number of steps:

First: Collecting measurable assessment inputs: 

In this step, the most important comments and notes of all phases are collected and documented from their sources, for example notes written by specialists responsible for reviewing, auditing and analyzing data collected from administrative records. Comments and notes provided by data users after publishing the data are collected and documented. Feedback taken from various mass media as well as clients’ comments sent to GASTAT main channels are also considered.

Second: Assessment:

Collected assessment inputs are analyzed, and the results of this analysis are compared with pre-anticipated results. Accordingly, potential improvements and solutions are identified and discussed with specialists and experts; and concerned parties are duly involved. In this phase, the performance and satisfaction of clients’ use of the results of the Energy Efficiency Statistics Publication are measured. Based on that, recommendations are developed to enhance the quality of the results of the next publications.

Ninth Phase: Management:

It is a comprehensive phase applies to each phase of the Energy Efficiency Statistics production.
