Innovative Light and Shade @ Pratt
   Pratt Institute's Energy Conscience Architecture Professor Brent Porter, is leading innovation in lighting design through his efforts in the Christina Porter Lighting Lab. The Christina Porter Lighting Lab presented a pin-up of its recent work, Feb. 22 - 24 as a precursor to plans for Pratt Institute's GREEN WEEK. Projects include a Velux Skylight research and a "roofscape" design exploration. Tyler Kicera modeled his ventilating skylight system with slanting interior soffits to deflect sunlight as well as artificial light as simulated in the Lighting Lab. Both "daylighting" and "night-lighting" blend together on a cloudy day. The slanting soffits have a double function similar to the skylights by Louis Kahn at Yale's British Art Center. This "roofscape" work is being expanded to tame Rhino and Maya computer languages for the Navy Yard market development as well as other student projects. This includes the aquatic center in Third Year Design. While generating form according to script, why not make the unique computerized extractions provide daylighting throughout the year, add passive solar gain in winter but shadow the interior in summer as skylights draw hot air from the architecture? Photovoltaic arrays can provide the hot spot at roof level adjacent to skylights to enhance the "thermal stack" effect. In the exhibition, the latest photovoltaic collector demonstrated how not only 90 per cent of the coating converts sunlight to electricity but also provides a surprising amount of daylighting to the interior below. A variety of sundials and solar envelopes illustrated their use for studying a design's access to sunlight without shading neighboring properties. The same techniques can be used to develop skylights and detailed roofscape. The work shown returned to the Pratt area's brownstones and what can be done with one indigenous element of the roof: the ventilating, skylighted cupola. Simulations showed how the thermal stack can cool row-housing in summer while not only enhancing daylighting of stairwells but also incorporating camera obscura techniques to bring color to an interior.
