Project Description
Glazing cost was reduced by increasing U value from 3.0 to 3.5. This was achieved by adding 38% more insulation to the walls and 26% more insulation to the ceilings.
Proposed residential dwelling (class 1a) is located in the city of Bell Buoy Beach. It consists of 3 levels with a net area of 160m2.
Through VURB method we managed to reduce overall glazing U-value by more than 15%.
Here are some more details on the degree of insulation and glazing thermal performance for the Bell Buoy Beach project:
| Item | NCC 2016 Reference Building | Proposal Building |
| Floor | R2.12 added to all suspended floors and common floors No insulation added to the slab on ground |
R3.0 added to all suspended floors and common floors No insulation added to the slab on ground |
| Internal and common walls | No insulation added to the internal walls R2.41 added to the common walls |
No insulation added to the internal walls R3.0 added to the common walls |
| External walls | R2.17 added to the external walls Solar absorptance: 0.6 |
R3.2 added to all external blockwork walls Solar absorptance: 0.6 R2.7 added to all external lightweight clad walls Solar absorptance: 0.6 |
| Roof/Ceiling | R4.74 added to the ceilings of all external roofs Solar absorbance: 0.6 |
R6.0 added to the ceilings of all external roofs Solar absorbance: 0.6 |
| External shading | Shading from other buildings and external eaves have been implemented into the analysis based on available drawings. | No new shadings proposed |
| Glazing | All ground floor east & west facing windows: U-Value: 3.0, SHGC:0.10 All other ground floor windows: U-Value: 3.6, SHGC: 0.81 All first floor windows: U-Value: 1.75, SHGC:0.28 |
Sliding Doors: U-Value 3.1, SHGC 0.47 Fixed Window: U-Value 2.7, SHGC 0.51 Awning windows: U-Value 4.7, SHGC0.47 |
