Proposed Restaurant @ St Helens, TAS – JV3 Performance Solution
Services
Our added value
We were engaged in the project to keep the aesthetics of an industrial shed inside the eatery area of roughly 260m2 (i.e. exposed metal purlins and visible roof cladding). This meant that we had to achieve energy compliance knowing over the eatery area of the proposed building, the roof/ceiling construction achieves no more than R0.15, compared to the Reference value of R3.7 (extracted from DTS pathway). For the services, the eatery area was meant not to be artificially cooled, and for heating, radiant overhead heaters were to be used locally. Performance Solution under NCC Vol 1.0 was, therefore, the only possible solution to overcome these shortcomings.
Using commercial rigid insulation with a high R-value (90mm R3.7), we managed to save a great deal of required thermal energy to heat the eatery, bar area and cinema. Adding under-slab and slab edge insulation to the existing concrete slab was not an option; Therefore, we tried to improve large Bi-Fold door thermal performance instead while considering the cost-benefit of it. We also proposed the condensing boilers for the supply of domestic hot water (with a 13% higher full load efficiency compared to the Reference). On top of that, to further offset the electricity demand, especially for the lighting demand and the cinema’s heat pumps, we proposed a Solar PV arrangement over the rooftop.
