With the new NatHERs minimum set to change to a 7-star energy rating, you may be wondering how to go about building a new house that meets the target. 

With buildings in Australia accounting for nearly 25% of carbon emissions it is not surprising that buyers are looking to build more sustainable homes.

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.

A large proportion of Australian architects have followed suit with their English counterparts developing Declare Australia in an attempt to promote a self-sustaining and constantly regenerating environment for future generations. But, what impacts will this have for property developers and builders going forward?

Getting a BESS statement can be a drawn out and frustrating experience with councils. To get a BESS statement requires a variety of factors such as management, water, energy, stormwater, Indoor Environment Quality (IEQ), transport, waste, urban ecology and innovation. With IEQ being weighted at 16.5% towards BESS certification, here are four ways where you can improve the Indoor Environment Quality of your next commercial or residential project, while being one step closer toward BESS certification:

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.

Advent of wind power as alternative energy source

The Vortex wind generator represents a radical change within the alternative energy market and conventional wind turbine design. This generator has no spinning blades (or any major moving parts at all), and appears to be a large cylindrical structure which oscillates in the wind producing energy. Instead of spinning like conventional wind turbines, its uses the principle of vorticity, which is the spinning and repeating motion of air and other fluids.
