Reaching a height of 223 feet (68 m) at 16 stories above grade, Alpha Rotex is the crown jewel of Quartier Alpha on the western edge of Gateway Gardens in Frankfurt, Germany. Gateway Gardens, an impressive new development project aimed at providing a sustainable, mixed-use hub adjacent to the Frankfurt International Airport, will be one of the first districts in the country to be certified under the DGNB German Sustainable Building Council standard. In order to meet the ambitious energy consumption and emission reduction targets for the site, buildings must be built and operated in accordance with the rigorous specifications of the German Energy Saving Ordinance (EnEV), which many buildings are set to exceed by 30% or more.

Baumann Consulting performed Commissioning (Cx), LEED and performance modeling services for this LEED for New Construction (LEED-NC) version 3.0 Gold certified project. In addition to LEED energy modeling services, Baumann also performed CFD (computational fluid dynamics) studies for the 8-story interior winter gardens to achieve both occupant comfort and natural ventilation goals. Performance models were also developed to allow operations staff to maintain carefully designed thermal comfort profiles within spaces such as the conference rooms and offices.
