Renewables energy specialist Vestas is to move its North American sales and service headquarters into the historic Meier & Frank Depot Building in downtown Portland, Oregon.
The 82-year old building will undergo a complete historic renovation by Gerding Edlen Development at an estimated project cost of $66m.
Once redeveloped, the building will be 172,000ft², including a 22,000ft² addition on the fifth floor with an eco-roof terrace and gardens.
Features of the renovated building will include roof-mounted solar panels, a system to collect rainwater for reuse in the building, raised-access flooring with under-floor mechanical ventilation, energy-efficient walls and a multistorey atrium to provide natural light.
The building will be designed with the intent to achieve LEED (Leadership in Energy and Environmental Design) Platinum certification.
Renovation is expected to begin in October 2010 and Vestas is planned to occupy the space in early 2012.
