Green Hall II Completed in 2017

Green Hall II, located in Vilnius, Lithuania, is a commercial building that was completed in 2017. The main contractor for this project was UAB Upės projektai, with architectural design by Arrow Architects and ARCHINOVA. The development was spearheaded by SBA koncernas.

Energy-Efficient Double Façade

The building's double façade spans over 5600 sq. m. and serves as an energy-efficient feature, preventing overheating during summer and preserving warmth during winter. This façade system not only helps in maintaining a stable internal temperature but also significantly reduces energy consumption. It incorporates aluminium-glass constructions manufactured in Germany, which allows it to meet the highest thermal resistance standards for passive houses with an impressive heat transfer coefficient of 0.6 W/m2k.

Eco-Friendly Insulation Methods

The project showcases environmental consciousness through the use of eco-friendly castor oil-based insulators instead of traditional petroleum-based polymers in the window systems. Additionally, the façade offers excellent sound insulation with a sound insulation coefficient (Rw) of 40 dB, effectively reducing city noise and creating a conducive environment for focused work on significant projects.
