HEATING AND COOLING CALCULATIONS

Original Design:

- Total Area: 342 m2

- Total Volume: 1226 m2

- Total Building Fabric Heat Loss: 8293.06 Watts

- Total Building Fabric Heat Gain: 8367.43 Watts

- Steady State Heat Loss: 529.36 Watts

The main source of heat loss from the original was the timber decking with a total figure = 3821.23 Watts

The main source of heat Gain in the original design was also from the timber decking, = 5155.78 Watts

It would be beneficial in the refine to decrease these figures, as the climate is very hot and with such a great figure for heat gain established from the floor. This can be reduced by decreasing the total area of the design.

By reducing the area and by effect the volume, it would also benefit the Embodied energy and water figures.

Refined Design:

- Total Area: 235.6 m2

- Total Volume: 353.4 m2

- Total Building Fabric Heat Loss: 4427.27 Watts

- Total Building Fabric Heat Gain: 6067.67 Watts

- Steady State Heat Loss: 276.03 Watts

The Main Source of Heat loss in the redesign was from the Timber decking with a total = 2632.40 Watts

The Main Source of Heat Gain in the redesign was found also from the Timber decking = 3551.76 Watts

Total Reductions:

- Total Area: Reduced 32 %

- Total Volume: Reeduced 71.2%

- Total Building Fabric Heat Loss: Reduced 45%

- Total Building Fabric Heat Gain: Reduced 25%

- Total Steady State Heat Loss: Reduced 47%

Conclusion:

Overall by reducing the total area and volume of the original design as well as changing the materials and their heat loss U values, the refined design benefited massively.

Though the Heat Gain was still relatively high through the timber decking, there was still a huge reduction of 31.12 %.
