What is NatHERS Star Rating?

The NatHERS star rating is a numerical representation of a building’s thermal performance and energy efficiency. A higher rating signifies a more sustainable and energy-efficient design. This rating is determined through the evaluation of factors such as insulation, orientation, ventilation, shading, and materials used in construction. The ultimate goal is to minimise the need for artificial heating and cooling, reducing a building’s environmental impact while providing comfortable living conditions for its occupants and reducing running costs.

Benefits of a Higher Star Rating:

  1. Reduced Energy Bills: One of the most significant advantages of a higher NatHERS star rating is lower energy consumption. Homes with excellent energy efficiency require less heating and cooling throughout the year, translating to substantial savings on utility bills for residents.
  2. Enhanced Comfort: A well-insulated and ventilated home maintains a more stable and comfortable indoor temperature, reducing the need for heating and cooling adjustments. This results in a pleasant living environment all year round.
  3. Improved Health and Well-being: Efficient ventilation and insulation can prevent moisture buildup and minimise the risk of mold growth, creating a healthier living space for occupants. Improved indoor air quality enhances overall well-being.
  4. Environmental Impact: By decreasing energy usage, buildings with high star ratings contribute to a reduced carbon footprint. Embracing energy-efficient living promotes a sustainable future for our planet.


Norwest Quarters’ impressive 7.8 NatHERS star rating is a testament to Mulpha’s commitment to sustainable design.
