This is both an indoor air quality enhancement during habitation and renovation, as well as a safety improvement since ﬁreproofing is easily damaged in renovation but sprinklers are not. Renewable Future Rinker Hall was designed for a future massive photovoltaic upgrade, incorporating the near threshold technology of dye-sensitized nanocrystalline solar cells. First patented by Dr. Graetzel in Lausanne, Switzerland between 1990 and 1993, dye-sensitized nanocrystalline solar cells are transparent and use both direct and diffuse light. Current applications of the cells are moving up in scale from watch crystals and cameras to glazing assemblies. The building anticipates this emerging technology through building orientation and organization. For example, the entire mechanical room for the building has been located at grade on the south end for ease of access and to leave the roof ﬂat and open for maximum future solar harvest. The roof has the capacity to hold 8,500 ft² of monocrystalline silicon photovoltaics and the east-west glazing can accomodate 10,110 ft² of transparent dye-sensitive nanocrystalline photovolatics. Incorporation of this renewable technology would yield an average 10 W/ft² peak from the roof, 4 W/ft² peak from the east-west glazing, and an overall 122.64 kW. For reference, this is approximately 90% of the current 135 kW peak demand (although it would not be simultaneously available). PERFORMING BUILDINGS 17 The building benefits from the cooling effect of the shade pattern. live oaks. Rather than a two-story building, the team designed a threestory building to minimize the site footprint and provide for more vegetated areas and open space. The cooling effect of the building’s shade pattern on the north and east was used. The building’s shade beneﬁts the construction yard on the east and the north entry patio and lobby, which merge with the adjoining shade canopy. Furthermore, the assembly area on the north and the construction shop on the east, both in excess of 2,000 ft², have been fully or partially incorporated in the design as indoor/outdoor spaces, taking advantage of thermal shading and sheltering attributes at the edge condition of the building. uninterrupted space runs in concert with the structural system from north to south, which is the unobstructed direction for growth and change based on a 4 ft module. The large scale of this open access anticipates technology upgrades and replacements. Additionally, to maintain free space from exterior wall to central spine for future north-south growth, moment connections rather than the less costly shear walls provide seismic resistance at the intersection of columns and beams. Walls are shifted off structural lines to eliminate intersections with columns and simplify Access Mapping Access mapping requires the consolidation and simpliﬁed routing of all basic support systems including mechanical, telephone, data and sprinkler. This highway of services is mapped over the ﬂoor plans to ensure nondisruptive servicing and large-scale access.
