MANUFACTURING IDEAS
DESIGN INTENT New York City has replaced an economy based on manufacturing to one based on ideas. It is a hub for the creative class. Professionals in the creative class have replaced looms and industrial equipment as tools for economic development with education and personal computers. Loft buildings are still in New York City, either empty like 330 Hudson or under utilized as apartment buildings. Converting lofts to hubs for the creative class will create the space and opportunity for young companies to flourish. Sharing expensive resources, like conference rooms and photo studios, will enable economic development. Co-working offices enable the building to be utilized 24 hours a day, making it a center for economic and cultural development. Views in between work spaces and the creation of communal space foster the development of ideas. Amenities like a roof top sculpture garden and ground floor retail allow residents within the building to promote their wares.
LOFTS IN NEW YORK SoHo LES, Brooklyn, Hell s Kitchen Williamsburg E. Williamsburg, Bushwick 1960 s 1971 1973 late 1970s 1978 1980 s 1982 1987 2008 2010 Loft Law expanded to North Brooklyn. Artist-in-residency requirement begins to be enforced after years of being ignored. Non-artists residing in SoHo and NoHo were permitted to grandfather themselves. Loft Law is amended to inlcude Brooklyn and loft districts known as M zones. NYC Loft Board regulates conversion of lofts to residential. Loft Law offers rent protection to residents in SoHo. Exodus of artists to Lower East Side and Brooklyn begins. Lower Manhattan Loft Tenants is founded. Over 30% of loft owners trying to remove tenets as rents rise. The area received landmarks designation as the SoHo-Cast Iron Historic District in 1973. Zoning permits Joint Live-Work Quarters for Artists. Artists migrate to SoHo.

330 HUDSON Architect: Charles Haight Year designed: 1910 CURRENT STATUS: A plan for a mixed use hotel began in October 2007 and was supposed to be ready for occupation in January 2009. The site stalled and was foreclosed by Trinity, dissolving relationships between Trinity and Tribeca Associates. Plans for the hotel have been nixed as it was said that the hospitality market wouldn t stabilize as quickly as the office market. (Source: Crain s) BENEFITS: Available FAR of 4 Large open floor plates Vacant Strong building structure
LOFT BUILDING STRATEGY 1. Increase building size to maximum FAR 2. Improve base building construction 3. Maximize program 4. Open shafts for ventilation and light 5. Adjust geometry of roof to promote ventilation through shafts 6. Create shading to reduce amount of solar gain ELEMENTS FOR STRATEGY 1. Anh Minh Ngo s Structural Addition 2. Contractors! 3. Architects! 4. Jason Roberts Light Void 5. Julie Jira s Open Air Canopy 6. Justin Fabrikant s Habitat Attack
STRUCTURAL ADDITION by Anh Minh Ngo ENVIRONMENTAL ISSUES ADDRESSED: Intantiating Anh Minh s element on the roof allows for the building to grow to its maximum FAR by creating structural support for additional floors. Increasing capacity of an existing building reduces need for new construction and makes the existing building more efficient. 330 Hudson was intended to be much taller than it currently is, so any additional weight can be supported. DESIGN INTENT: It is instantiated with attention to structural necessities and setback laws. It changes to create connections with public areas. USER REQUEST: Publish output points on top corners of structural addition to facilitate in adding more floors INPUTS: Building geometry, number of columns needed in each direction. OUTPUTS: Building area added, structure weight added, material costs for building, construction costs for building, profitability in 10 yrs.
LIGHT VOID by Jason Roberts ENVIRONMENTAL ISSUES ADDRESSED: Jason s element acts as a ventilation shaft through the building. Instantiating his louver panels in some portions of the frame UDF allows for controlled ventilation. Increasing ventilation within the building helps with the additional heat load produced by all the people and plug load. Increased light reduces electrical lighting loads for the building. DESIGN ISSUES ADDRESSED: It provides visual connection between floors and offices and allows everyone to have access to natural light and ventilation. In linear instantiations it is shaped for light while more varied instantiations are responding to program. USER REQUEST: Four input points from the original three. INPUTS: Column grid (from building and Anh Minh), existing floor conditions, cage subdivisions, slab curve radius, panel type. OUTPUTS: Area of void, percentage of floor area removed, area of void facade, volume of void, floor to floor height, percentage of panel to pipe, quantity take offs, new glazing percentage of floor, new air changes per hour of floor, new r value of floor, air changes per hour of void itself. Jason Roberts, jer2161@columbia.edu VoidSolid
OPEN-AIR CANOPY by Julie Jira ENVIRONMENTAL ISSUES ADDRESSED: The shape of the roof geometry is adjusted to promote ventilation and laminar floor with help from Drew s research. Julie s Open-Air Canopy pulls air through the LightVoid and helps maximize ventilation through the building. DESIGN ISSUES Static ADDRESSED: ETFE Panel It crease additional (Double public Layer) space by allowing a sculpture garden on the roof and it indicates the location of shared resources in the building. USER REQUEST: Four input points from the original three. INPUTS: Building points (from Anh Minh), LightVoid points, surface, panel angle, subdivisions of surface. OUTPUTS: Area of panels Medium Resolution - Low Intelligence NYC Research Element Design Metrics Building Strategy Application Collaboration Evolution
HABITAT ATTACK! HABITAT ATTACK! by Justin Fabrikant ENVIRONMENTAL ISSUES ADDRESSED: Justin s element will provide shading on the sunniest facades to reduce internal gains where the sunlight is the strongest. The depth of the habitat will be changed according to solar angle. It will also collect run off water from Julie s element. DESIGN ISSUES ADDRESSED: Habitat Attack! creates additional program space that will congregate around Justin s LightVoids. USER REQUEST: Four input points from the original three. INPUTS: Facade points (from building and Anh Minh), length of cantilever, depth of planter, floors. OUTPUTS: Dimensions, self weight.

WIND JANUARY WINDS The roof is shaped to promote ventilation through LightVoids. Wind patterns influence shape of roof. Optimizing the ventilation strategy for 330 Hudson allows for an increase the comfort of the building. JUNE WINDS
VENTILATION BASE CASE ATRIUM FOR ORIGINAL BUILDING Temperatures increases 1.1 degree for every vertical foot. Vertical shafts pull air through the building for passive ventilation on two scales - the large scale of the enclosed atrium and the smaller scale of the Light Voids. The building addition creates the height necessary for ventilation. ATRIUM FOR BUILDING WITH ADDITION
INTERIOR LIGHTING LIGHT ON 11th FLOOR In addition to ventilation, the LightVoids carry light into the building. Optimal range for interior lighting is 2-6.
