Home assessment for Energy Rating

A home sustainability assessment can help to identify where you can make the biggest energy and water savings in your home and save money.

The assessment will involve an inspection of major energy and water systems—heating and cooling, lighting, refrigeration, cooking, and entertainment systems.
The assessor may look at your previous energy bills and will examine water efficiency (indoors and outdoors). This information is entered into an assessment tool to give you a tailored report for your home. Home assessments usually only take an hour or two depending on how much information you can supply, the size of your property and the number of energy and water systems you have.

When choosing an assessor check they're accredited.  Accredited Assessors should be qualified and experienced building performance professionals.  Their focus is making a difference to improve built environment outcomes.  

How much does a HERS building thermal performance assessment costs?  
The type and complexity of the building design will determine the cost – for example it can range from $200 - $400 for a standard building design and $400 - $1500+ for a more complex building design.
You should also find out what topics are covered in the home assessment and the level of advice you'll receive in the report. Your assessor should take into account the local climate as well as your specific circumstances. Standard topics include:
•    thermal rating
•    energy usage
•    water usage
•    household waste
•    advice on the costs of improvements & government legislation on related issues.

Your assessor may also be able to provide information about rebates for implementing improvements in your home. Do your research as some banking institutions provide special low cost loans to their customers to enable them to take practical action to save energy and money. Follows our steps to getting a home assessment to ensure you gain the best value from your home assessment.
