At Novartis we carry out energy audits and reviews to assess the maturity of energy management practices and the level of conformance of existing buildings and equipment to the internal energy standards. The results of energy audits/reviews enable us to identify and determine respective improvement opportunities for energy efficiency improvement and greenhouse gases (GHG) emission reductions of existing buildings and installations.
For each Division, Novartis has a program of regular energy audits/reviews that include as a minimum the major sites and the key buildings with regard to energy consumption at these sites. The annual planning of energy audits/reviews is based and prioritized on energy and GHG emission performance parameters, and the results of prior data collection.
Below, you find a detailed description of the Novartis energy audit process.
Novartis’ Energy Audit Process
Audit Preparation: Energy audits/reviews are announced in advance, defining the date, the scope and the objective of the audit/review and the audited/reviewed unit is usually requested to complete in advance a preparatory questionnaire in order to capture the basic information and to streamline the process.
Audit Execution: The duration of the energy audit/review depends on the size of the unit analyzed (entire site, multiple or single building, or part of building only) and type of activities of the unit analyzed (cleanroom, production, laboratory, warehouse, office). Energy audits typically last for 1 to 3 days, including report writing and discussion of the draft report, while energy reviews can widely vary on duration depending on the scope of the review and the size of the unit reviewed. Energy audits/reviews will take significantly more time in cases where additional data need to be gathered, energy alternatives need to be evaluated, or if benchmarking data is unavailable due to lack of metered data. This may extend the auditing process as temporary or permanent meters need to be installed and suitable time elapses to gather representative data. Trial measures may sometimes also be required to ensure reasonable accuracy of the savings projected. Both energy audit and review normally comprise interviews, inspections and verification activities. Site or unit management ensures that appropriate contact persons are available throughout the analysis.
Energy audits (as any other audit) formally start with an opening meeting in order to explain the objectives and the audit process, and conclude with a closure meeting in order to present and discuss the results of the energy audit. Specific questions for various types of operational activities are included in the Novartis Energy Survey Checklist and can be used as the basis of energy reviews/audits. They could be used as the basis for the preparatory questionnaire or as a checklist for the analysis.
Audit Report: A draft report is prepared during the visit. It includes key information about the unit analyzed, description of its major energy aspects, and the positive and negative audit/review findings. A finalized written report is completed after the audit/review and includes an executive summary, description of the situation, and the findings. It also comprises recommendations for improvement actions towards higher energy efficiency, resource savings, GHG emission reduction and use of renewable resources.
Audit Follow-up: The unit analyzed establishes an action plan with deadlines for the implementation of the corrective actions and recommended improvement actions and sends it to the Divisional Energy Manager. These action plans are monitored and followed up by the respective Divisional Energy Manager or engineering departments. The results of the action plan may also be reviewed by the Division on site visits and during Corporate and Divisional HSE audits.
The Site Energy Manager conducts the necessary energy reviews at the site. External expertise and resources are acquired if necessary. The Corporate Energy Manager receives a summary of the Divisional energy audit reports from the Divisional Energy Manager as part of the reporting on the Energy Audit Program. The Divisional Energy Manager evaluates the effectiveness and results of the site energy reviews and the resulting improvements. The Divisional Energy Manager also organizes for or conducts the Energy Audits for the Division and maintains a Divisional Energy Auditing Program.
The Group Energy Manager evaluates the effectiveness and results of the Divisional Energy Auditing Programs and the resulting improvements. He/she can initiate individual energy audits and support Divisional Energy Auditing Programs.
