This paper describes the development, design, and construction of an early green building, the NMB Bank Headquarters in Amsterdam. The integrated project team worked across disciplines to design the building. The team included architects, construction engineers, landscape architects, energy engineers, and artists. This paper details the green characteristics of the building, including the floor plan, daylighting, insulation, and energy system. Interior artistic characteristics also add to the building’s green qualities. Construction on the building finished in 1987 and it is therefore a prototypical green development.
