Dr. Dimitrie Gerota Emergency Hospital has been developed in full accordance with NZEB (Nearly Zero Energy Building) performance criteria. The entire building envelope is engineered as a high-performance thermal enclosure, ensuring compliance with all NZEB standards.

 

The façade incorporates a combination of glazed and opaque elements using multiple advanced façade systems, including:

​

• Stick curtain wall (CW) system

• Double-skin façade

• Mesh screen façade

• Channel glass façade

• Ceramic-clad rainscreen system

• External insulated façade system

• Mesh roof screen system

 

A custom stick curtain wall system is designed with horizontally and vertically protruding mullions, incorporating integrated LED lighting to satisfy the architectural design intent and enhance the building’s nighttime identity.

To meet the overall architectural objectives, a custom double-skin façade with an outer aluminum mesh layer has been developed. The perforated mesh provides a unique architectural expression while maintaining a lightweight structure. The system enables modular fabrication and installation for improved constructability and quality control.

​

How NZEB (Net Zero Energy Building) compliant facades are designed?

​​

• Selecting appropriate TGU (Triple Glass Unit) responding to the NZEB requirements with U values under 0.8 W/m2K

• Research for the high thermal insulation featuring stick curtain wall system with thermal isolator in both mullions and transoms.

• Introducing a double step bracket system with thermal blockers to eliminate thermal bridging. 

• Proper thermal infilling of all cavities behind the facade systems and interfaces with the building structure.

• Special care in detailing of rainscreen facade systems to benefit from the ventilated cavity to increase thermal performance while using high performance thermal insulating cladding materials.

​

A full scope of façade consultancy services was provided to the architectural design team, including:

​​

• Façade material studies and technical evaluations

• Performance criteria development and compliance advisory

• Detailed façade design packages and shop-drawing coordination

• Performance-based technical specifications

• Bill of Quantities (BOQ) preparation

• Structural system integration and coordination

• Multidisciplinary interface review and resolution
