Frequently Asked Questions
What does the auditing process involve?
Every site is different, but typically energy data (electricity, gas, diesel, LPG and/or coal bills) supplied by the client is used to prepare information that can highlight areas of concern during the site investigation. A detailed site inspection is then performed, taking note of all energy using equipment/processes and identifying areas where the energy consumption can be reduced without negatively effecting production or space conditions. Calculations are performed for the energy saving opportunities and the capital cost is either estimated or obtained from contractors. A report is prepared, outlining the energy use onsite (both end use consumption and historic consumption) and the energy tariffs, and provides detailed descriptions of energy management opportunities. These descriptions include energy cost savings and estimated capital costs, allowing the client to make economically correct decisions.
Is it true that the government provides funding for an audit?
Yes, typically EECA (Energy Efficiency and Conservation Authority) refunds up to 33% of the audit cost for projects consuming in excess of $250,000 year. Further details can be found at http://www.eecabusiness.govt.nz/services-and-funding/audit-grants.
How long does an audit usually take?
The length of the audit does vary, but from the site inspection to submission of the draft report is typically 8 weeks. This allows time to gain quotes from contractors, perform our in-depth technical analysis and prepare the report.
What does an audit cost?
An energy audit typically costs 0.5% - 12% of the annual energy cost depending on the size of the building or plant. We are happy to provide no obligation indicative pricing and/or formal proposals on request.
