The Knotter office building required a complete rebuild. The front entry needed to be redesigned because they had taken over the whole building and previously there had been multiple companies within the space. The heating and cooling was a challenge because the entryway was made mostly of glass, making so traditional heating and cooling could not be used. We also installed a 600-ton high-efficiency cooling tower. The existing cooling tower was undersized and inside the building. There was also a fume issue because the exhaust was located near the air intake for the building. We relocated the new 600-ton tower to the roof.
