CORE: a new programmatic core is the counterpart of the piazza of the courtyard. It serves as a circulation backbone, connecting the formerly disparate departments of architecture, landscape architecture, and the CSBR, catalyzing interaction between these departments and integrating the CSBR into the university culture. The core also serves as a passive strategy; it pours diffuse north light into the new atrium and pulls stale air out of the building through stratification.
REACTION: the inner-facing and universal Cerny building is acknowledged and re-interpreted in the CSBR addition. The reclusive “O” is broken into a South-facing “C”, exposing the inner loop circulation to generous south light and opens the building to cool summer breezes.
LAYERS: the CSBR addition is conceptualized as a series of delaminated layers, gradually opening to the South of the building, forming a gradient of spaces from seasonally exposed outside courtyards to semi-enclosed meeting spaces to fully sheltered workspaces. Layers are exposed on the East and west facades, but continue through the building, defining separations in program.

Outdoor demonstration area with protection from wind andconnection to interior space
Lab spaces set back from glass to reduce allow only indirect daylight
Deep overhangs on 4th floor corridor allows direct sun in winter but shade in summer
ZONE 1: THERMAL FLUX57-80° F (conditioned range)
Most direct connection to exterior thermal conditions. Temperature shifts with season, sunlight intensity, and weather.
ZONE 2: SOUTH FACING65-78° F (conditioned range)
South facing areas that take full advantage of direct passive gains. Shading devices allows occupants to regulate temperature.
ZONE 3: NORTH FACING65-78° F (conditioned range)
Fewer windows and increased insulation for thermal stability. Limited passive gains from adjacent zones.
THERMAL PROGRAM ZONES
ZONE 1: SOLAR FLUX 500-1500 lux
Most direct connection to exterior atmospheric conditions. Shifting light conditions according to season, time, and weather.
ZONE 2: FULL DAYLIGHTING 300-750 lux
Direct sunlight controlled through louvers and light shelves to minimize need for electrical lighting during occupancy hours.
ZONE 3: AMBIENT DAYLIGHT 200-350 lux
Ambient north light provides lower but even light quality with points of task lighting as needed.
ZONE 4: MINIMAL DAYLIGHT0-300 lux
Low occupancy spaces with minimal daylighting required.

LIGHTING AND HEATING STRATEGY (PASSIVE + ACTIVE)
WALL SECTION SYSTEMS INTEGRATION
Waldsee BioHaus, Bemidji, MN [Stephen Tanner of INTEP, Inc]Porextherm Vacupor® VIPs meet the requirements of the German energy conservation provision EnEV without dramatically increasing the insulation thickness. They allow a slimness, which offers more space for design and is ideal for inside and outside areas.
Waldsee BioHausMade of spruce/fir, cork, larch, and aluminum cladding, Optiwin’s 3 wood window is the “world’s finest window.” It achieves the German Passivhaus Certification with an over all R-value of 8.0.
Toronto City Hall, Toronto, Canada [PLANT Architect Inc. / Shore Tilbe Irwin & Partners]An extensive green roof offers a delightful outdoor space for work and demonstrations as well as thermal insulation in the winter and cooling in the summer. Local vegetation will connect with the surrounding environment, attract wildlife, and collect/filter rain.
School Complex, Pichling, Austria [Loudon + Habeler]In the winter, fresh air is pre-heated through geothermal heat exchange and pre-cooled in the summer. Exhaust air is collected for heat recovery through rotary heat exchanger. The core of the building will act as a thermal chimney.
Omega Center, Rhinebeck, New York (BNIM Architects)The Omega Center takes full advantage of photovoltaic roof panels, geothermal, thermal masses, natural ventila-tion, passive cooling, daylighting, passive heating, and shading.

MATERIAL INVENTORYCERNY BUILDING MNZEDHOLL BUILDING
RELATIONSHIP TO CERNY: the CSBR offices acknowledges and reinterprets the aesthetic of the existing building. While the universal regularity of the existing windows of the first two floors are not directly continued upwards, the eight-foot spacing of the windows forms the basis of columnar structure and the expanding spacing of the layers. The black-painted steel of the floor bands are carried up into the vertical louvers of the addition, while the mass of the brick changes to board-formed concrete, drawing on existing materials.
NORTH FACE: The north and south faces of the addition, rather than expressing the cross-section of the concept, show the faces of these slices. The north face is made up of five compressed layers, the outermost of concrete, the inner layers are a soft underbelly of wood, barely visible in the window sections. The window placement articulates inner program needs; narrower windows reflect spaces adjacent to the light-filled core space, wider windows are adjacent to spaces higher daylighting needs. The form of the windows is a hybrid between the vertical slots present in the Cerny building and the punched squares in the Holl addition.
