An Energy Audit is a comprehensive evaluation of your home or small building using specialised equipment, the evaluation is then used to develop a custom plan to improve the energy efficiency and comfort of your home while reducing energy costs.
An improvement in energy efficiency within your organisation can potentially bring significant business benefits. With this in mind, SGS has developed energy audit services to help you find the best information for improvement opportunities.
Standards Australia has developed new standards for undertaking energy audits—the AS/NZS 3598 series. The series has three standards to cater for different types of activity:
- 3598.1 Energy audits – Commercial buildings
- 3598.2 Energy audits – Industrial and related activities
- 3598.3 Energy audits – Transport related activities
The new standards replace the single AS/NZS 3598:2000 Energy audits standard, which was based on energy audits of commercial buildings. It emphasised process, had relatively light technical requirements and the energy audit levels were not tightly defined.
How is it completed?
An Auditor will begin with a thorough visual inspection of the interior and exterior of the home including the attic, basement and crawl spaces, followed by an accurate measurement of the interior volume. Depending on the construction of the home they will then use a blower door to create a vacuum in the home.
They will then once again inspect the exterior walls and ceilings using a smoke pencil and will scan all of the surfaces with an infrared camera to find areas of air and thermal leakage. Because the recommendations will include specific instructions on reducing air infiltration they might will also conduct a thorough safety inspection of your gas burning appliances.
What type of recommendations will they make?
Recommendations will be specific to our findings for your home but may include items such as caulking areas to reduce air leakage, adding insulation in attics and walls, and re-sealing or replacing windows and doors.
Recommendations will have a strong emphasis on the “low hanging fruit” where small expenditures can have an immediate effect on comfort and a short term payback with reduced energy consumption.
Who completes the improvements?
The report will contain specific recommendations for improvements, if you choose to proceed with any of these recommendations you may use any contractor of your choice. Most would be happy to prepare a proposal to complete these items for you, or if you prefer to complete any of these improvements yourself, they would be happy to provide guidance along the way.
