Heat Modelling Data Set

Housing Performance Interactive Data Set

How well does a standard house perform in a tropical climate zone, with 11 occupants, no active cooling system, and windows always open? This interactive tableau is based on the modelling represented in our AHURI report Sustainable Indigenous Housing in Regional and Remote Australia. We modelled housing performance for 366 scenarios, based on parameters for: arid, tropical, and hot/mild climate zones; standard and improved house design; occupancy density; cooling system; and ventilation (see report Table 9, p.73). Results show temperatures today and according to future climate projections. See for yourself by selecting specific inputs.

Scenario A – no active systems, window always open;                                    Scenario B – no active systems, window always closed;
Scenario C – no active systems, natural ventilation;                                        Scenario D – no active systems, night purging—windows open during the night;
Scenario E – non-ducted cooling system in living areas and main bedroom, natural ventilation;
Scenario F – Ducted cooling system in all rooms, natural ventilation;           Scenario G – split system plus heating in living room, natural ventilation.

The ‘standard’ house design is based on housing commonly found across remote Australia, while the ‘improved’ building has been modified to meet National Construction Code guidelines for the relevant climate zone.

Climate zones are drawn from the Australian Building Code Board’s, specifically: Climate zone 1 – high humidity summer, warm winter (Tropical); Climate zone 3 – hot dry summer, warm winter (Arid); and Climate zone 4 – hot dry summer, cool winter (Warm/mild). The indoor temperature daily trend is modelled for current climate and future climate projections.
