RETROFITTING EXISTING BUILDINGS

Retrofitting focuses on improving existing buildings so they perform better in how they use energy, water and systems.

The BASIX assessment and NatHERS process is an ever evolving practice which requires extensive knowledge of available materials, passive heating and cooling strategies and how to design in an ecologically sustainable manner. Although to complete and sign off on the BASIX process one must be a certified assessor. The assessor’s background does not play a large role in determining their competency in assessing a building’s efficiency. Therefore, the question is raised as to who is the most qualified or most knowledgeable to be completing the BASIX assessment?

You really need to check with the council. 
While not particularly a ‘relocatable home’ as it sounds like an existing residence, not a new prefab one, this is the only information on the BASIX website:

NatHERS, (or Nationalwide House Energy Rating Scheme), provides a rating system to determine the thermal comfort of Australian homes through software simulations. This system rates from zero to ten stars. The more stars a home gets the more comfortable the occupants will feel when living in the house/unit without additional cooling or heating systems. A building is unlikely to need any artificial heating or cooling system if it gets a 10 star rating.

Prior to commencing most types of developments in NSW, you will have to lodge a Development Application (DA) with your local council. 

Suntuitive's dynamic thermochromic self-tinting glazing has many benefits such as elevated mood, increased levels of concentration and higher productivity. However, a common question is: does it perform as well in cold climates as it does in warm?

It is important that designers modify their designs in relation to the climate in which they are built in. In order for the occupants of a home to remain thermally comfortable, the design must work with the climate, not against it, decreasing the need to use heating and cooling systems.

Renewable energy and heating sources are rapidly evolving and becoming more popular every year. Now as these technologies are becoming more and more widespread with smaller communities wanting to incorporate renewable energy in smaller scale development.

The abundance of carbon dioxide in the atmosphere is one of the the largest problems in modern society, therefore, creating ways to capture and store Carbon Dioxide is of high importance. An international team of researchers is working on a new technology to transform carbon dioxide into stone. Scientists are already changing CO2 into carbon and plastic but now they’ve found the next solution. This potentially could mean that you can store CO2 below the ground by "transforming" it into stone.
