Full remodel of a historic warehouse into a LEED Platinum mixed-use facility with state-of-the-art environmental systems

This project was a full mechanical core and shell remodel of a historic warehouse building into the new headquarters for solar panel manufacturer Vestas, and included a commercial ground floor, second floor parking garage, and two renovated floors. A fifth floor was added with roof gardens, solar panels, and rain water harvesting.

The new headquarters also features an open auditorium, multiple conference rooms, and private office spaces.

Our Approach

For the fifth floor addition, we installed a raised floor HVAC distribution and perimeter variable refrigerant flow (VRF) units. Two mechanical rooms serve each floor with new rooftop units supported by a strengthened roof diaphragm.


Using extensive planning and innovative collaborative processes, our team successfully met project milestones and requirements. The project is LEED Platinum certified and listed on the National Historic Registry.
