US-based architectural firm Interactive Design (IDEA) plans to reclad the AJ Celebrezze Federal Building in Cleveland, US, using double-skin technology.
IDEA says that this will be the first time a US high-rise has been reclad using double-wall technology.
The recladding will involve placing a new external curtain wall 2.5ft beyond the face of the original building skin to create a double wall with the existing façades forming the internal portion.
The double-skin technology is intended to minimise temperature variances by insulating the building while maintaining visual purity.
The east and north façades of the building are transparent with perpendicular interior fritted glass fins that filter and modulate the oblique light that these sides receive.
Glass edges on these façades are detailed to float over the existing building to highlight the new performance skin.
The south and west façades have been developed with a double-wall construction to provide an insulating envelope in winter and reduce heat in summer.
The façades also feature horizontal light shades to reduce direct sunlight while the glass is treated with a graduated frit pattern from almost opaque to clear from bottom to top.
The recladding is being funded through the American Recovery and Reinvestment Act (ARRA), according to glassguides.com.
