Project Description
Glazing cost was reduced by increasing averaged U value from 4.5 to 5.2. This was achieved by adding 47% more insulation to the floors and 36% more insulation to the ceilings.
Proposed commercial building (class 9b) is located in the city of Promised land.
Through JV3 Performance Solution 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 Promised land project:
| Item | NCC 2016 Reference Building | Proposal Building |
| Suspended Floor | R1.7 added to the suspended floors | R2.5 added to the suspended floors |
| Internal and common walls | No insulation added to the internal walls. | No insulation added to the internal walls. |
| External walls | R2.52 added to the external walls | R2.5 added to the external walls |
| Roof/Ceiling | R3.31 added to the ceilings of all external roofs | R4.1 added to the ceilings of all flat roofs. R5.4 added to the ceilings of all pitched roofs. |
| External shading | Shading from other buildings and external eaves and shading have been implemented into the analysis based on available drawings. | No new shading proposed |
| Glazing | All east facing windows: U-Value: 3.0, SHGC: 0.15 All other facing windows: U-Value: 6.0, SHGC: 0.53 |
All windows: U-Value: 5.2, SHGC: 0.43 |
