What is Energy Auditing?

Energy Auditing is a tool for identifying energy efficiency potential and measures. An energy audit is an important tool or method for finding such potentials for energy efficiency measures and for assessing their financial viability, which can be carried out at different levels.

A simple level just includes a brief site inspection as well as assessing the broad energy input and output of a system – this identifies low cost energy saving opportunities.

Medium level audits include an in-depth analysis of energy costs, energy usage and system characteristics along with on-site energy demand measurements to identify energy efficiency measures which are more capital intensive and need to be aligned with the financial budget plan of the site.

The most sophisticated level, which is referred to as an investment grade audit, includes an additional continuous monitoring of system data and process characteristics.

Energy audits on such comprehensive levels can also form an important basis or first step for introducing and establishing energy management systems (EMS) in enterprises/ other institutions. They enable efficient management of energy demand and consumption in production or processing entities – also in agricultural value chains (International Standard for EMS: ISO 50001).

The Main Goals of Energy Audit

Understanding how energy is used within the system or process, and where it is wasted
Finding alternative measures to reduce energy losses and improve the overall performance
Performing a cost-benefit analysis for highlighting which energy efficiency measures are best to implement

Phases of Audit

01Review of Energy Use

In this phase of the auditing process the energy use of the system, e.g. a small diary milk factory, is assessed by reviewing the energy bills or the past fuel consumption patterns in the past. Also, a system diagram is sketched showing the energy flows within the system along with a list of used equipment and their energy demand. The more detailed the energy usage data, the better will be the actual analysis. At this point, monthly data is most common; however, daily or even hourly data would be more accurate. With the collected data the auditor is able to calculate the total energy demand for specific scenarios (seasonal variation/ production intensity) and is able to set each system component into comparison. Then, it is possible to determine a “per square meter” energy use or “an energy use per produced product unit”, to benchmark the system against other similar buildings or processes. With these preliminary analyses, experienced auditors can estimate how much potential the system or building bears for efficiency improvements.

02Site Assessment

During the site assessment, the mentioned system components are examined and their performance data is collected. This step can include, for example, the operation characteristics of a fan used for drying or the lighting used throughout the building. Such a process can vary largely in terms of effort.

03Data Analysis

The data analysis step is the most complex part of an energy audit and involves technical and cost analysis. Methodologies for analyzing the collected data vary widely and are subject to the system or process to be assessed. The technical analysis can incorporate a simple spreadsheet energy balance where all input and output parameters are determined or can be achieved by designated software packages. The same methods apply for the cost analysis, where current energy costs, costs for implementation of energy efficiency measures as well as potential savings over time are considered. The results of both analyses lead in a further step to a hierarchy of the most promising changes to the system in both financial and technical aspects. Guiding indicators are amongst others the payback period, life cycle costs as well as internal rate of return of the energy efficiency measures. Further aspects to be considered are operation and maintenance of planned implementation, reliability and their ease of installation.

04Audit Report

The last phase of the auditing process is creating a comprehensive report, including all recommended energy efficiency measures and how different combinations lead to cost and energy savings.

In A Short

Energy auditing is the analysis of process or system in regard to their energy usage and energy losses.
By reviewing load patterns, executing site visits and measuring process energy demands, suitable energy efficiency measures can be discovered.
Energy audit results are useful for economic and environmental betterment of the analyzed processes, thus it is a very important tool in energy sector.

Green FinanceWhat is green finance and why is it important?

Green finance is any structured financial activity that’s been created to ensure a better environmental outcome.
The value of green bonds traded could soon hit $2.36 trillion.
The European Central Bank is getting heavily involved in green finance.
The top three green bond issuers are the US, China and France.
The World Economic Forum’s Green Horizon Summit focuses on how green finance can help in the recovery from COVID-19.
Green finance is blossoming. Globally, the green bond market could be worth $2.36 trillion by 2023. It is regarded as a way of meeting the needs of environmentalism and capitalism simultaneously .
At its simplest, green finance is any structured financial activity – a product or service – that’s been created to ensure a better environmental outcome. It includes an array of loans, debt mechanisms and investments that are used to encourage the development of green projects or minimize the impact on the climate of more regular projects. Or a combination of both.

Funding sustainable development

For the United Nations, green financing plays an important role in delivering several of its Sustainable Development Goals. Its Environment team is already working with public and private sector organizations in an attempt to align international financial systems to the sustainable development agenda.

Some of the activities UN Environment is involved in include helping countries re-engineer their regulatory frameworks – so that green borrowing becomes compliant, for example – and helping steer public sector planning in a more environmentally friendly direction.

Clean sources of energy can be brought to fruition through the right combination of planning consent, strategic priorities and availability of capital. Such projects could be given preferential treatment to make them a more attractive option than, for example, fossil-fuel derived energy infrastructure.

Typical projects that fall under the green finance include:

Renewable energy and energy efficiency
Pollution prevention and control
Biodiversity conservation
Circular economy initiatives
Sustainable use of natural resources and land
Growing international interest
