Passive Strategies and Double Skin Facade South Facade: Double Skin Facade with Seasonal Dynamic Shading

Columns within facade Operable windows

Floor to ceiling mullions, “spider” clamp fittings Dynamic louvres 1200/2000 frameless triple glazed units

Sofitel-Vienna-Stephansdom-Stilwerk

• Double-Skin Facade to South elevation, with integrated dynamic louvres, consisting 1200x4000 frameless triple-glazed panels, supported by internal floor to ceiling mullions and spider-clamp fittings • Rainscreen timber-clad 1200x4000 SIPS panel construction with vertical frameless glazed STUDENT strips 50:50 panel:glazing ratio to West and 75% PRODUCED BY AN AUTODESK PRODUCT panel:25% glazing ratio to North. SIPS panels affixed to frame via vertical 2x4 timber studs spanning floor-to-ceiling • Thermal bridging eliminated by glazing and sips panels concealing floor slab from external facade • Louvres automatically adjust (seasonally) to optimum sun angle to regulate direct solar gains, and protected from mechanical damage or tampering • Floor-to-Floor cavity brick wall construction to East neighbouring property • Operable windows encourage cross-ventilation, aided by the stack effect of the double skin facade during summer, with the potential to increase ventilation rates when necessary, without increasing mechanical fan speed

• SIPS panel construction reduces the cooling load on the non-shaded West facade, whilst minimising heat losses to the North • Comfortable temperature ranges from 18°C to 23°C and SHGC to South regulated according to requirements by double-skin dynamic shading simulation • Annual heating load minimised to 21 kWh/m2, close to passive standards of 15 kWh/m2 • Internal and solar gains not sufficient to provide enough heat during winter months, a top-up heat source may be necessary in these instances
