Rufus Spheres, Amazon's headquarters building in Seattle, is unique in that it appears to be composed of three connected floor-to-ceiling glass balls. The building consists of steel frames, and the glass as the façade contains five separate spaces. 6038 meters, is the center of the city's headquarters building area of about 320,515 square meters. This project was designed by architects of NBBJ, and Magnusson Klemencic has been entrusted as the engineering office. It is a highly energy efficient building with a LEED GOLD certification. Been one of the biggest concerns for this project, which is why our silent, energy-efficient heating solutions proved useful and fitted perfectly. We have supplied 250 heat exchangers (a total of 300 meters) for a custom built-in application. A good cooperation between the interior architects, engineering office, and Jaga has led to a seamless integration of our products into the interior of the building.
