Two building designs are considered for this study, one is a sustainable design unit called ‘The cove’ and another is a typical suburban Melbourne house. Both the houses were modelled in IES VE 2018 in current climate using Melbourne Moorabbin location with RMY (representative meteorological year) simulation file. 
Results of which are compared with respect to Annual energy intensity (kWh/m2 ), Peak heating and cooling load along with Annual hourly min, max and mean temperatures of Bedroom2 and Family room. Same models are then simulated in 2050 warmest future climate scenario, results are compared between all of them.

•    Energy intensity of courtyard in current climate is 205.98kWh/m2 which is 10 times greater than that of the cove- 20.17kWh/m2. While in the future climate scenario energy intensity of courtyard is 243.36kWh/m2 which is almost 11.5 times greater than cove in future climate which is 21.07kWh/m2.
•    When considering chiller and boiler load for future climate, it is found out that the boiler load decreases for cove from 8.34kW to 5.50kW and for courtyard from 20.11 kW to 14.13kW. However, there is increase in peak chiller load from 5.71kW to 6.30kW for cove and from 18.68kW to 24.83kW for courtyard.
•    Min., max. and mean temperatures of cove for both bedroom2 and family room in future climate has increased by 0.6-1.3 oC when compared with current. While there is drastic increase in min., max. and mean temperatures of bedroom2 and family room in courtyard of 1.1- 3 oC.
