Sustainability Report

Precast concrete system

• Reduces material waste through factory-controlled production

• Improves quality control and durability

• Shortens construction time, lowering site-related emissions

Optimized façade geometry

• Twisted vertical precast concrete slats designed with Eurac Research to reduce overheating

• Eliminates need for external shading devices, reducing additional material use

Durable, long-life materials

• Exposed reinforced concrete structure

• Polished concrete floors

• Triple-glazed solar-control glass

• Ceramic tiles

• Modular timber interior elements in event space

Exposed MEP systems

• Simplifies inspection and replacement

• Avoids unnecessary secondary finishing layers

KlimaHaus A performance (33 kWh/m²a)
Indicates very high thermal performance and airtight envelope.

Photovoltaic system

• Rooftop PV generates electricity daily

• Surplus electricity used for hydrogen production

Hydrogen storage system (metal hydride technology)

• Stores surplus solar electricity

• Provides emergency off-grid operation

• Enables autonomous supply to ventilation systems during power outages

Renewable contribution

• 70% of primary energy demand from renewables

• 47% of hot water demand from renewables

Passive solar control

• Rotated vertical concrete slats reduce summer overheating

• No external shading required

• Triple glazing with solar control coating

Precast system

• Reduces long-term façade degradation

• Allows partial replacement instead of full reconstruction

Exposed MEP installations

• Easy inspection

• Reduced demolition during upgrades

• Lower maintenance waste

Grid ceiling with integrated heating/cooling

• Modular disassembly

• Facilitates future technical replacement

Durable finishes

• Concrete and ceramic materials require minimal replacement cycles
