SemperGreenwall Brings Nature to International Square Washington D.C.

The International Square building is situated in the core of Washington, D.C.’s Central Business District. International Square is a venue for culture, experiences, and all that the city has to present. The building has been recently renovated, with the goal of establishing a hub where one will flourish! The International Square has been converted into a center for both work and life, from dining to culture, to enhance the way you work, connect, and create.

Extends facade lifespan

A living wall shields your facade from the sun, rain, wind, and temperature changes, extending its lifespan.

An organic feel

One of the inspiring places is the immense culinary food hall within the center. The SemperGreenwall is installed around the food hall atrium, mounted all around the first floor landing. The living wall is a very important part of the space’s aesthetics, with many rather hard industrial and or dark building elements, the green wall brings in a natural, soft, and organic feel. With the inclusion of the SemperGreenwall, the client achieved a warmer and more natural/biophilic aesthetic of the food hall.

Hexagon shape living wall

The continuous Hexagon shape makes the SemperGreenwall extremely impressive and the real eye-catcher of the area. The 220 sqm (square meters) living wall is elevated about 10 feet off the floor.

Lighting and plant design

The initial design of the SemperGreenwall did not include artificial lighting, but for plant growth, it was assumed that the skylight above the entire living wall would be sufficient. In some areas on the living wall, a more shade-tolerant mix of plants was chosen. However, during the installation, it became clear that artificial lighting was critical for the performance of the living wall and therefore added. The palette of plants did not need to be altered for new light conditions.

The SemperGreenwall gives the atrium a very welcoming, natural, and calm atmosphere.
