BASIX Thermal Comfort

BASIX Thermal Comfort


 

The thermal comfort section of the BASIX assessment tool is on a pass / fail basis rather than being based on performance scores. To get a pass mark a dwelling must have a certain thermal heating and cooling load for it to be comfortable throughout the year. In Rapid and DIY methods of BASIX thermal comfort assessment, cooling and heating loads are being calculated by the online BASIX assessment tool based on the characteristics of the building. In thermal simulation method, these loads are calculated by a certified NatHERS thermal assessment software and the results are being inserted in the online assessment tool in form of a valid ABSA Certificate by an ABSA Accredited Assessor or HERS Assessor. Heating and cooling loads are being addressed separately in the BASIX and therefore a more informed approach is being followed compared to NatHERS star ratings which are the summation of heating and cooling loads.

Three factors determine the maximum heating and cooling loads; climate zone, floor construction type and development type. Three types of floor construction are recognised in BASIX tool, slab on the ground, suspended floor with open sub floor and suspended floor with enclosed sub-floor. BASIX considers each dwelling in a multi-unit apartment, the average of all units and separate dwellings as three different types of construction with different BASIX maximum heating and cooling loads. Also, there are 21 different climate zones in NSW and in each climate zone, the thermal comfort loads are different for each combination of the previous two factors.
