Why A NABERS Rating Tool Is Not An Indication Of Thermal Comfort

Although a good start, the current National Australian Built Environment Rating System (NABERS) rating methodology is falling short of the standards set by the rest of the world. Suggestions have been made to increase the scope of Thermal Comfort testing to include more reference to ISO 7726 and ISO 7730 International Standard for Measuring and Assessing Thermal Comfort.  NABERS Energy rating, which is the assessment tool to meet CBD (mandatory disclosure) is only related to energy consumption and has nothing to do with the thermal comfort of the occupants within this building.  Additionally, the NABERS rating tool does not point at specific criteria for building improvements.

In countries such as the UK and the US, they have taken further steps to ensure Thermal Comfort by implementing programs and regulations that focus on one particular aspect of a build; the building envelope as an air barrier.

Stopping unwanted air infiltration into commercial and government

buildings are one of the most important and cost-effective ways to reduce heating and cooling costs, improve indoor air quality, and provide a more reliable, energy efficient construction.

The building envelope is the boundary, which separates outside air, moisture and wind from the inside conditioned space. In fact, the importance of the air barrier is such that current and future air barrier testing standards are currently being incorporated into new residential and commercial building codes around the world. The new regulations will no doubt significantly impact construction techniques in the coming years.
