scenarios

Scenario #1 – high rise/new build
The [|Freedom Tower and Solaire] are examples of green skyscapers more and more commonly seen in the city. At 7 WTC, some examples of green building include: The Solaire includes:
 * more open space for the public,
 * more natural light,
 * glass that conserves energy by blocking heat and uninhibiting light,
 * excellent indoor air quality through the use of a high-efficiency filtration system,
 * steam to electricity turbine generators, variable speed fans,
 * harvesting rainwater for reuse in the cooling system and for irrigating the park,
 * waste reduction through diversion of more than seventy-five percent of construction waste and
 * use of recycled content materials.
 * carbon dioxide monitoring equipment
 * gas absorption chillers
 * The solar array provides 33 KW of power.
 * Extensive green roofs include only 2”-6” of planting media and support short ground cover vegetation, such as Sedums, and require minimal maintenance.
 * The wastewater treatment system is a Syncro Flo system that processes 250,000 gallons of wastewater per day.
 * All appliances are Energy Star rated, including the Bosch Axis washers and driers.
 * Seven day programmable thermostats
 * recycled content medium density fiberboard
 * formaldehyde-free wood
 * cherry wood veneer cabinets.

Public works projects are also going green. The [|Grand Avenue Bus Depot and Maintenance Facility] harvest rainwater to wash its buses, and the St. George Intermodal Ferry Terminal is being upgraded to enhance environmental quality. [|Con Edison] has a "green roof' program.

Educational centers are at the forefront of green building. The[|Science Barge, [|Brooklyn Center for the Urban Environment], [|Brooklyn Children's Museum], [|Bronx Zoo's Lion House], [|Williamsburg Daycare Center], and [|Queens Botanical Garden] have all renovated their buildings to be more aligned to sustainability principles.

Many techniques exist for retrofitting existing building to be more sustainable. [|Armstrong Tile Recycling] will take old, water damaged tiles on site and truck them to their processing plants to be reproduced as new tiles. [|Bettencourt Green Building Supplies] stocks bamboo and Bakota Burl wood stocks that are sustainable for many generations. [|Build It Green!] is continually involved in deconstruction projects that save old drawers and wood stock for future projects.The [|Green Depot] offers non toxic paints that reduce VOC in the air.

[|439 Metropolitan Avenue], [|Melrose Commons V], and [|The Octagon] are examples of smaller living spaces that are applying green technologies, such as solar energy panels. Even the [|Vatican] is putting solar panel on top of its bascilicas.

The [|Gottfried House] and [|Brooklyn Brownstone] are examples of small homes that are going green.
