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:
