A Comprehensive Guide to NatHERS Assessment

It is mandatory to obtain NatHERS certification for all new developments that include multiple dwellings, although NatHERS Assessment also applies to single-family homes. Do you want to purchase a new home or renovate your current one in NSW? Then this blog is for you.

  1. A Comprehensive Guide to NatHERS Assessment All new Australian residential construction and renovations costing over $50,000 needs to achieve a 6 star energy rating as outlined in the National Construction Code (NCC). The Nationwide house energy rating scheme,commonly known as NatHERS assessment, provides residential constructions with energy and thermal comfort star rating ranging from 1 to 10. The rating is based upon the structure's design, construction material and location of the project. The Australian harsh and unforgiving climatic conditions necessitate the construction of energy-efficient homes. However, only a few projects were able to achieve 10-star NatHERS rating. While NatHERS assessment is specifically reserved for residential constructions, the BCA section J report deals with commercial constructions. What Is 6-Starts NatHERS Rating? A thermal or energy efficient rating Indicates how much artificial heating and cooling is required to maintain a comfortable interior thermal temperature.

  2. Consequently, a six-star rated home will have greater thermal efficiency than a 5 star-rated construction. in simple words, a six-star rated home will most likely consume 24% less energy for artificially heating and cooling a house. What’s Included Within A NatHERS Assessment? A NatHERS assessment evaluates the following components of residential construction: When evaluating a new home and its compliance with a 6-star energy rating, an assessment considers the ‘skin’ of the building and materials that make up the home as well as environmental factors such as climate and orientation. These include: ● ● ● ● ● ● ● ● ● ● Location and climatic zone of the project Orientation with respect to the north Construction materials for flooring, wall and roof Windows/glazing details including size, location, frame material and type of glass Insulation of ceiling, roof, wall, and floor, including materials, dimensions and brand Exterior finish such as roof and wall colours Ventilation, including provision and size Placement and size of ceiling fans – size and placement Provision for natural light and artificial lighting fixture details Floor coverings such as carpet and hard floors.

Some features of sustainable residential construction can also be applied in commercial projects to achieve compliance with the BCA section J report. Understanding the orientation of a building Proper orientation can considerably enhance the comfort of the interiors while reducing dependency on artificial heating and cooling appliances. The most optimal orientation for your residential construction is the one that suits your climate.

  3. Considering the climate zone while designing According to the National Construction Code, Australia experiences 8 fundamental climatic zones. It is particularly crucial to ensure that your residential project is specifically designed to suit the prevailing climatic zone. Different passive design concepts are applicable to different climatic zones. Passive Design Concepts- Heating and Cooling Passive solar heating allows the winter sun to provide thermal. With passive heating concepts, the building envelope is designed in a way to retain the natural or artificial heat inside. Passive cooling utilizes the concept of ventilation, unrestricted air movement, evaporative cooling and thermal mass to maintain a cool temperature within the interiors. Passive heating and cooling are important components of the NatHERS assessment. Appropriate glazing Window and door glazing have an incredible impact on your residential building's thermal performance. Improper glazing and window placement can lead to approximately 40% heating energy loss and 87% unnecessary heat gain inside the home. Select a glazing and window orientation that's right for your climatic condition. Wrapping Up Only a few Australian residential constructions have attained the aspirational pinnacle of 10-star energy efficiency. Hire an experienced building consultant to achieve a higher rating and enjoy greater market value and reputation through sustainable design concepts.
