450 Warren named Archdaily Building of the Year!

450 Warren Street, designed by Brooklyn based architects SO-IL has been voted Archdaily Building of the Year in the Housing award category.
Text from the architects:
“A community means shared spaces for living and relaxing together, but also informal interaction. Neighbors see one another’s comings and goings across the way, and a shared entry courtyard encourages chat. Transparent materials allow light and changing seasons to permeate the building’s activity.”
As building envelope consultant LaufsED advised on façade options, material choices, constructability and the thermal and structural performance of the façade.






















We're delighted to share AUDI AG's new sustainable dealership concept store in Germany featuring an approximately 500 m² facade of Made of Air's novel biochar composite. The material is made from >85% atmospheric carbon content and acts as an engineered carbon sink.
By replacing a typical aluminium facade system, Made of Air's facade prevents the re-emission of ca. 12t of CO2 from waste biomass and avoids emissions. The building has been awarded Gold Status by the DGNB German Sustainable Building Council.
LED provided structural facade engineering services including fastener testing and Review for the design team, Made of Air, Berlin.
The new Mennica Legacy Tower three-story lobby façade in Warsaw is Poland’s largest glass cable net wall, opened in 2019. Class A office space inside the highrise tower can be entered via the one-way cable wall system, which has partial curved areas and utilizes a transparent glazing that “blurs the boundary between interior and exterior space” (Goettsch Architects, Chicago). LED provided full proof engineering structural & façade detailing review, including 1:1 IGU glass warp tests and 1:1 cable deflection & tension tests to assure high safety of the locally edge-clamped glazing and cable end fittings.
We are proud to have worked with Tishman and Mariani Metal on this full-service project (calculations-shop-fabrication) and have designed and engineered the transit hall/lobby curtain walls with blast-resistant building design throughout. Although LED worked together with Mariani Metal to complete almost all metal-related fixtures and assemblies in the transit hall, (w/ calculations and shop/fabrication drawings for these items) the brunt of the work relied on bomb-resistant glass wall design for the massive curtain walls and top hung 3-level glass floor system with intermediary bridges. The use of Duplex Stainless Steel was a key design element when engineering the curtain walls, mullions, transoms, brackets, and even nosing connections. Careful collaboration between Mariani and LED also allowed for a smoother and faster fabrication process which allowed for more installation time on-site.
LED has successfully reviewed the ultra-luxury condo glazed facade for Pritzker Prize winner Álvaro Siza's first-ever building in New York City, 611 West 56th Street, a unique 37-floor tall residential tower, developed by Sumaida + Khurana and Leny. This is also Siza's first-ever building in the US.
"Siza is world-renowned for the sculptural characteristics and purity of his buildings. The intricately constructed 80-residence monolithic tower will be wrapped in four sides of Perla Bianca limestone and reflect the subtle and refined detailing that Siza is known for."
Façade Contractor Aluprof developed, produced, and installed a bespoke unitized window wall system that seamlessly merges into the limestone skin with carefully placed joint lines. LED helped coordinate and PE-stamp all metal-glass envelope elements including all storefront facade types throughout.
