Green Square Complex
Green Square is the State of North Carolina's premier sustainable design project.
Under the aegis of the NC Department of Environment and Natural Resources (NC DENR), Green Square was developed, in the heart of the State Capital, as a three-block, multi-use, sustainable, urban development to house the NC DENR headquarters (150,000 sf) and the NC Museum of Natural Sciences' Nature Research Center (NRC - 79,400 sf.) Both facilities are connected to the existing NC Museum of Natural Sciences by sky bridges creating a three-block long complex dedicated to research, discovery, education and regulatory enforcement of the State's environment and natural resources. From the start, the intent of the Green Square development was and is to promote stewardship by example to the general public.
Sustainable strategies include:
High-efficiency building enclosure • Permeable paving along Jones Street sidewalks to reduce rate of discharge into the City stormwater system • Low albedo/reflective paving colors • 140,000 gallon capacity rainwater collection cistern for the reclamation of rainwater, condensate and reverse osmosis (RO) discharge for irrigation, flushing and cooling tower make-up • Indigenous plants • Green roofs • Energy efficient HVAC systems • 100% LED lighting in the HQ and 95% in the NRC (as demonstration projects for State facilities) • Occupancy sensors • Solar water heating • Photovoltaic power generation • Prismatic louvers that reflect daylight into the offices • Electronic monitoring of building systems • Maximized daylighting via light shelves, full glass atria, light tubes, prismatic louvers, and perimeter photo dimming • Solar shading over the atrium glass to control heat and powered by its own photovoltaic panels • Reclaimed wood for flooring and wall panels • Salvaged materials such as marble and brick from demolition of existing buildings
