Martini, Portsmouth, N.H.; and commissioning agent, Flack + Kurtz, Boston GREEN POINTS: Base building renovations for this 9-story building included core redesign and lobby renovation and upgrades. The design strategy left the existing Salada Tea lobby, vestibule and adjacent waiting area intact and called for the removal of signage and accessories to showcase the elegance and beauty of the original spaces, which were built in the early 20th century. The elevator lobby’s upgrade focused on creating a backdrop for the historic component of the building. Encompassing 94,000 square feet (8733 m2) of office space, the space utilizes natural daylighting with vision glazing in window transoms as part of the façade restoration. Lowflow fixtures and waterless urinals contribute to water efficiency and low-VOC-emitting materials were used. The project diverted 83 percent of demolition waste from landfills. It also earned a LEED for New Construction Certified rating from the U.S. Green Building Council, Washington, D.C.
