An energy efficiency rating is calculated using NatHERS Accredited Software as part of a NatHERS assessment. The NatHERS emblem on the Universal Certificate serves as evidence that the assessor who completed it is accredited by NatHERS. The main design elements of the home, the building materials, and the methodology used to determine the home’s star rating are all detailed in a NatHERS Universal Certificate.

Energy Score

The amount of heating or cooling required maintaining comfort in your development can be determined with accuracy by looking at the Energy or Thermal Efficiency star rating. An accredited NatHERS assessment assessor can determine a home’s energy efficiency by using licensed software to produce an energy rating. Please note that it does not represent the real energy consumption of the house, as that relies on the appliances that are installed and how they are utilized (only assessable after occupancy). By raising your energy efficiency, you’ll use less energy to maintain comfort in your home, resulting in cheaper energy costs and a much healthier atmosphere.

Stars

A scale with a possible range of 0 to 10 stars describes how energy-efficient a home is. A home with a star rating of 0 means that there is no insulation from the outside temperature. For instance, if the temperature outside is 20, the interior temperature will be 30. A 10-star residence, however, can always keep its interior at a reasonable temperature, regardless of the weather outside. Therefore, a house uses less energy the more stars it has, which lowers energy costs.

Do equipment like air conditioners and others have an impact on star ratings?

In general, no, as NatHERS assessment energy scores depend on how effectively the residence is designed. The building’s newly installed appliances that are expected to be replaced in the future are not taken into account.

Condensation: What is it?

The rise in humidity and seasonable temperatures brought on by climatic changes can be linked to the condensation risk in NSW. Increased condensation build up in the house might result in the growth of mould, which may have an impact on the residents’ health. Many professionals have expressed worry that the design and construction of buildings are leading to an increase in condensation levels because of the buildings’ enhanced levels of insulation, air tightness, and energy efficiency features. It’s crucial to remember that the new regulations aim to reduce health effects by managing condensation risk in NSW. Since dealing with condensation in buildings is a complex issue that depends as much on how the structure is used as it does on how it is created, it does not address condensation removal.

Does a building need to be ventilated?

Air tightness is occasionally cited as the issue when it can be a major component of the solution. In this lesson, we will discuss how to manage indoor moisture loads and thus condensation risk NSW by considering the function of various types of cavities within the building enclosure and the significance of adequate ventilation of the inhabited area.
