Project Description
Glazing cost was reduced by increasing U value from 2.0 to 2.6. This was achieved by adding 84% more insulation to the floor and 37% more insulation to the ceilings.
Proposed residential dwelling (class 1a) is located in the city of Blairgowrie. It consists of 1 level with a net area of 21m2.
Through VURB method we managed to reduce overall glazing U-value by more than 30%.
Here are some more details on the degree of insulation and glazing thermal performance for the Blairgowrie project:
| Item | NCC 2016 Reference Building | Proposal Building |
| Floor | R1.9 added to the suspended floor | R3.5 added to the suspended floor |
| Internal and common walls | – | – |
| External walls | R2.24 added to the external walls Solar absorbance: 0.6 | R2.24 added to the external walls Solar absorbance: 0.6 |
| Roof/Ceiling | Total R5.1 added to the ceiling and roof Solar absorbance: 0.6 | Total R7.0 added to the ceiling and roof 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 shading proposed |
| Glazing | All windows and door: U-Value: 2.00, SHGC: 0.5 | All windows and door: U-Value: 2.60, SHGC: 0.5 |
