Located at the edge of Manhattan between the High Line park and the Hudson River, 40 Tenth Avenue takes its unique form from the geometric relationships between the building’s allowable envelope and the sun’s path, as well as the viewshed between the park and the Hudson.
Solar Carve successfully responds to these needs while protecting the public space of the High Line. Designed according to a particular “solar carving” strategy, the result is a gem-like façade created by faceted glass panels across the angled sections of external wall.
The complexity of these units has been challenging to design, but we succeed in finding the perfect bespoke solution able to comply with the architectural purpose. Hudson River, you had better accept our façades are going to be the new mirror of New York’s skyline.
The glazing system have been geometrically optimized into a pattern of three-dimensional facets that articulate the carved sections of the tower. The curtain wall unit consists of a central diamond-shaped panel tiling downward, surrounded by four triangular pieces that are perpendicular to the slab to achieve standard stack joints. The carved curtain wall not only blocks sun glare and heat gain, but also creates dynamic corner workspaces. The façade features high-performance glass with low-iron reflectivity.
Sustainability: Targeting LEED Gold
The building’s shape was informed by the path of the sun over the site, with sections removed from the cuboid form to prevent blocking light and views. The result is a “gem-like facade”, created by faceted glass panels across the angled sections of external wall.
For this project, our technical department has designed two main bespoke curtain wall systems:
EWT 1 – EWT 2:
Standard units dimension of 5’ width (about 1520mm) by 16’ height (about 4870mm) for the cladding of East and West elevations.
The Double Glazed Units consist of a heat-strengthened pane on the outside and a tempered monolithic pane on the inside. The DGU Low-E coating is Ipasol neutral 38/23 for the typical floors and Ipasol neutral 70/37 for the laminated panes of the storefronts at ground floor level 1. Aluminum profiles are dark grey powder painted and AAMA 2605 10 years Florida test certified.
EWT 3 Carved units:
Five pane tridimensional units 8’x8’ feet square base for a typical height of 16’ feet, each one with four triangular glasses and a rhomboidal central one. This curtain wall system features on North and South elevations, creating an aesthetic effect of carved façade that is extremely original and iconic. The Double Glazed Units consist of both inside and outside laminated panes, with Ipasol neutral 38/23 coating. Aluminum profiles are dark grey powder painted and AAMA 2605 10 years Florida test certified.
The building envelope has been completely 3D designed in a close synergy with Studio Gang NYC. All the systems have been weather tested by INTERTEK institute, where the behavior of the façades was also tested for seismic action, in accordance with the guidelines of the NY building code and the American AAMA, ASTM, etc. regulations.
