Completed in 2015, 1601 Wewatta Street played a large part in its neighborhood’s enhancement. The 10-storey Class AA office tower is located in Denver’s Commons area, just west of the 125-year-old Union Station, which underwent significant redevelopment in 2014. More than 100,000 commuters descend on the Commons each day.
1601 Wewatta is clad in aluminum and glass curtain wall and elegant stone cladding. Projecting glass parapets, horizontal sunshades and unique cladding segmentation visually tie the tower’s cladding to the ground floor streetscape.
Challenge: The building had aggressive goals for energy performance coupled with a unique, complex and attractive design. As is often the case, design elements such canopies, terraces and unique cladding elements can create challenging lines, parameters and shapes that are not conducive to good building envelope performance and complicate continuity of the building envelope in terms of air, vapour, heat and water.
Solution: We worked with the architects to maintain the desired aesthetic appearance while boosting overall performance of the building envelope “behind the scenes,” in the materials, systems and assemblies used in the exterior walls and roof areas.
