When Alberici built their new corporate HQ they went Green and incorporated a mix of an existing building (27%) with new construction (73%).
The facility is very Green:
"Rating: U.S. Green Building Council LEED-NC, v.2/v.2.1--Level: Platinum (60 points)"
"Rating: Green Globes --Level: Four Green Globes"
"This project entails the adaptive reuse of an existing manufacturing plant into a corporate headquarters for one of St. Louis' oldest and largest construction companies."
"The ... client achieved their goal of Platinum LEED(r) certification; the project earned 60 points, the highest total ever. The company now enjoys a healthy, comfortable, beautiful environment that fosters teamwork, creativity, and collaboration, and a 50-year-old structure has new life."
"Retention ponds and constructed wetlands retain all of the stormwater runoff and form a filtration process in the forebay pool, removing 80% of total suspended solids and 40% of total phosphorous from stormwater discharged into the ponds. The site had been half covered by impervious surface but is now its own watershed."
"Rainwater from 60% of the garage roof area (42,200 ft2) is stored in a 30,900-gallon cistern. From there it is filtered through a strainer and sand filter, chlorinated, held in a secondary 500-gallon tank, and used for 100% of sewage conveyance. The captured rainwater is also used in the mechanical system’s cooling tower. The sizing of the cistern was informed by 27 years of local rainfall records. The cistern’s overflow drains into the north retention pond, one of two ponds on site. This pond is a living ecosystem with fish, frogs, and predacious aquatic invertebrates. Native plants combine forces with flowing, infiltrating water to promote biodiversity."
"The reuse of rainwater, along with the use of water-efficient fixtures, results in a 70% reduction in potable water use, saving 500,000 gallons of water annually."
