The document discusses two green housing projects: 1) NOLA Shotgun LOFThouse(s) in New Orleans, LA, which are multi-family and single-family housing units inspired by traditional New Orleans shotgun houses that incorporate sustainable design strategies like passive solar heating and green roofs. 2) The Kalahari mixed-income housing in Harlem, NY, which is a dense mixed-use development with affordable and market-rate units that achieved LEED Gold certification and reduced energy consumption by 30% through strategies like geothermal heating/cooling and photovoltaic panels. The design celebrated African culture and promoted minority development.

40. Located in the heart of Harlem, the nation’s largest
African American community, the building proudly
celebrates its African culture. The brick patterns
and colors were inspired by the Kalahari African
tribal patterns painted on desert homes

41. The sustainable affordable and market-rate development creates workforce
housing with generous amenities and green technologies for families of
diverse backgrounds and income levels.

48. The financing was designed to protect the interests of long-term Harlem
stakeholders by making 50% of the units affordable and 50% market rate (the first
time in New York City) with a 50% preference for existing Harlem residents.

49. The undulating massing is a creative interpretation of the New
York City zoning code to provide alternating rhythm of tower and
wall along the building’s 300-foot football-field length.

50. 116TH STREET ENTRANCE ADINKRA SYMBOL
Harlem’s new, green 249-unit mixed-use, mixed-income condominium reflects the
richness and variety of Harlem's vibrant urban African-American cultural fabric.
The design was unanimously approved on the first vote by Harlem’s local
community board #10 and the New York City Planning Commission.

51. Shared public green roofs, day-lighted elevator lobbies, high-performance building
envelope and air filtration, heat recovery, motion-sensitive lighting and photovoltaic
panels reduced the building’s energy consumption by 30% below the norm.
