Based on the scope and objectives of the energy audit, a thorough planning phase is conducted to ensure the success of the audit program. This includes:

• Required Preliminary Information: Gathering necessary information and relevant data from the organisation to provide a solid foundation for the audit process;
• Time Period and Site Visit: Determining the appropriate timeframe to conduct site visits and complete the energy audit, ensuring efficiency and accuracy;
• Organisation Representative: Designating a representative within the organisation who will be responsible for coordinating and facilitating the audit process;
• Regulatory and Other Constraints: Considering any regulatory requirements or other constraints that may impact the audit process;
• Project Considerations: Addressing specific considerations related to the energy audit project, such as budget, resources, and unique organisational requirements.

During this stage, comprehensive energy-related data is collected, collated, and recorded to support the audit objectives. The following information is typically gathered, covering a period of at least 12 months:

• List of Energy Consuming Equipment, Facilities, Systems & Processes: Identifying and documenting the characteristics of energy-consuming assets within the organisation;
• Energy Consumption and Energy Bills: Collecting data on energy consumption patterns and reviewing energy bills to understand usage trends and costs;
• Relevant Variables: Considering variables that impact energy consumption, such as production levels, occupancy rates, or weather conditions;
• Energy-Related Measurements: Capturing specific measurements related to energy usage, efficiency, or performance;
• Operational History and Past Events: Examining historical operational data and events related to energy systems, highlighting any anomalies or significant changes;
• Monitoring Equipment: Taking into account the availability of monitoring equipment, such as distributed control systems, that can provide additional insights;
• Design, Operation, and Maintenance Documents: Reviewing relevant documents related to the design, operation, and maintenance of energy systems and equipment;
• Other Relevant Data: Incorporating any additional data or information that may be pertinent to the energy audit.

To ensure accurate on-site data measurement and collection, a comprehensive measurement plan is essential. The measurement plan outlines the key items that should be included and considered during the data collection process. The key items typically contained in the measurement plan are listed below:

• A list of measurement points and their measuring equipment;
• Measurement duration and frequency for each measurement;
• Accuracy and repeatability required for the measurements;
• Relevant variables provided by the organisation;
• Responsibilities for carrying out the measurements.

As an integral part of the energy audit process, site visits are conducted to gain a comprehensive understanding of your organisation’s energy usage and identify potential energy-saving opportunities. During the site visit, our experts perform the following activities:

(a) Observing Energy Uses:

We closely observe the various energy uses within your organisation, including equipment, facilities, systems, and processes. This allows us to gain first-hand insights into the energy consumption patterns and identify areas for improvement.

(b) Evaluating Energy Consumption:

We assess and evaluate the energy consumption levels of different assets and areas within your organization. By analysing historical data and conducting on-site measurements, we gather detailed information on energy consumption profiles.

(c) Understanding the Impact of Operating Routines:

We delve into the operational routines and practices employed within your organisation. This helps us understand how energy is utilised during different operational scenarios and identify potential efficiency improvements.

(d) Ensuring Representativeness of Measurements:

During the site visit, we ensure that the measurements taken are representative of your organisation’s normal operational practices. This involves verifying that the measurements accurately reflect the energy consumption patterns and usage trends.

(e) Validating Historical Data:

We cross-check the historical data provided to us with the observed energy usage during the site visit. This validation process ensures that the historical data accurately represents your organisation’s normal operating conditions and energy consumption.

(f) Revising and Finalising the Measurement Plan:

Based on the insights gained during the site visit, we may revise and finalise the measurement plan if necessary. This ensures that the measurement activities align with the observed energy consumption patterns and savings opportunities identified.

By conducting thorough site visits, we tailor our approach to reflect the specific energy consumption patterns and savings opportunities within your organisation. This enables us to provide customized recommendations that align with your operational practices and maximise energy efficiency. CAESL acknowledges the crucial role that site visits play in gaining a thorough understanding of your energy usage.

During the analysis phase of the energy audit, we focus on establishing and evaluating the current energy performance of the energy uses within your organisation. This involves a comprehensive assessment to identify areas for improvement and propose practical and cost-effective energy conservation opportunities. The key activities during this phase include:

(a) Analysing Energy Consumption and Efficiency:

We analyse your organisation’s energy consumption patterns and evaluate its energy efficiency performance. This analysis provides insights into where energy is being utilised and identifies areas with potential for improvement.

(b) Identifying Energy Performance Improvement Opportunities:

Based on the analysis of energy consumption and efficiency, we identify specific ways in which your organization can enhance its energy performance. This may include optimising operational strategies, implementing technology solutions, or introducing behavior change initiatives.

(c) Proposing Practical and Cost-effective Energy Conservation Opportunities:

We develop practical and cost-effective energy conservation opportunities tailored to your organisation’s unique requirements. These opportunities are designed to reduce energy consumption, increase efficiency, and deliver tangible savings.

(d) Estimating Costs and Benefits:

For each energy-saving opportunity identified, we estimate the associated costs and benefits. This analysis helps you evaluate the economic viability and potential return on investment of implementing the proposed measures.

(e) Ranking Energy Performance Improvement Opportunities:

To prioritise action, we rank the identified energy performance improvement opportunities based on factors such as energy savings potential, feasibility, and impact on organisational goals. This allows you to focus on initiatives that will deliver the greatest benefits.

As part of the analysis, we ensure that at least 90% of your organisation’s total energy consumption is covered, aligning with ESOS requirements. Additionally, the performance improvement recommendations can encompass a range of measures, including:

• Installing smart meters and energy data monitoring tools to enable real-time monitoring and management;
• Implementing changes to operation and maintenance strategies to optimise energy performance;
• Undertaking capital investment projects to upgrade equipment, systems, or infrastructure for improved energy efficiency;
• Initiating behaviour change projects to raise awareness, engage employees, and promote energy-conscious practices.

CAESL adopts a holistic analysis approach to pinpoint the optimal opportunities for enhancing your organisation’s energy performance.
