        | DESCRIPTION |  |  |  |  |  |   
                              |  |  |  |  
                              |  |  | 
                                  
                                    |  The expansion of The Nelson-Atkins Museum of Art fuses architecture with landscape to create an experiential  architecture that unfolds for visitors as it is perceived through each individual’s movement through space and  time.  The new addition, named the Bloch Building, engages the existing sculpture garden, transforming the entire  Museum site into the precinct of the visitor’s experience.  The new addition extends along the eastern edge of the  campus, and is distinguished by five glass lenses, traversing from the existing building through the Sculpture Park  to form new spaces and angles of vision.  The innovative merging of landscape, architecture and art was executed  through close collaboration with museum curators and artists, to achieve a dynamic and supportive relationship  between art and architecture. 
 As visitors move through the new addition, they will experience a flow between light, art, architecture and  landscape, with views from one level to another, from inside to outside.  The threaded movement between the  light-gathering lenses of the new addition weaves the new building with the landscape in a fluid dynamism based  on a sensitive relationship to its context.  Rather than an addition of a mass, the new elements exist in  complementary contrast with the original 1933 classical “Temple to Art”:
 
 ___Original Building_______New (in Complementary Contrast)
 ___Opaque _____________Transparent
 ___Heavy_______________Light
 ___Hermetic_____________Meshing
 ___Inward views_________ Views to landscape
 ___Bounded____________ Unbounded
 ___Directed Circulation____Open Circulation
 ___Single Mass__________Transparent lenses
 
 The first of the five “lenses” forms a bright and transparent lobby, with café, art library and bookstore, inviting the  public into the Museum and encouraging movement via ramps toward the galleries as they progress downward  into the garden.  From the lobby a new cross-axis connects through to the original building’s grand spaces.  At  night the glowing glass volume of the lobby provides an inviting transparency, drawing visitors to events and  activities.
 
 The lenses’ multiple layers of translucent glass gather, diffuse and refract light, at times materializing light like  blocks of ice.  During the day the lenses inject varying qualities of light into the galleries, while at night the  sculpture garden glows with their internal light.  The “meandering path” threaded between the lenses in the  Sculpture Park has its sinuous complement in the open flow through the continuous level of galleries below.  The  galleries, organized in sequence to support the progression of the collections, gradually step down into the Park,  and are punctuated by views into the landscape.
 
 
  The design for the new addition utilizes sustainable building concepts; the sculpture garden continues up and over  the gallery roofs, creating sculpture courts between the lenses, while also providing green roofs to achieve high  insulation and control storm water. At the heart of the addition’s lenses is a structural concept merged with a light  and air distributor concept:  "Breathing T's” transport light down into the galleries along their curved undersides  while carrying the glass in suspension and providing a location for HVAC ducts. The double-glass cavities of the  lenses gather sun-heated air in winter or exhaust it in summer. Optimum light levels for all types of art or media  installations and seasonal flexibility requirements are ensured through the use of computer-controlled screens and  of special translucent insulating material embedded in the glass cavities.  A continuous service level basement  below the galleries offers art delivery, storage and handling spaces, as well as flexible access to the "Breathing-  Ts." 
 
  The ingenious integration of art and architecture included a collaborative effort with artist Walter De Maria, one of  the great minimalist artists of our time.  De Maria’s sculpture, One Sun /34 Moons, is the centerpiece of the  expansive granite-paved entrance plaza with a reflecting pool that forms a new entry space shaped by the existing  building and the new Lobby “Lens”.  The “moons” of the art work are circular skylight discs in the bottom of the  pool that project water-refracted light into the garage below. Conceived as a vehicular Arrival Hall, the garage is  generously proportioned, directly connected to the new museum lobby on both levels, and spanned with  continuous undulating vaults by an innovative pre-cast concrete ‘wave-T’. 
 A strong relationship between the architectural concept and the Museum’s important oriental art holdings is  illustrated by works in the permanent collection such as Verdant Mountains (12th century) by Chiang Shen or The  North Sea (16th century) by Chou Ch'en, which demonstrate the timeless merging of art, architecture and  landscape.  The new addition celebrates this fusion with the new Isamu Noguchi Sculpture Court, setting a  binding connection to the existing Sculpture Gardens.

                                    | The lenses are woven into the landscape of the 22-acre Sculpture  Park, and space between the lenses will feature simple ground  covering on the gallery roofs, including grass and low shrubs.  This  green roof system manages storm water and provides high  insulation value and thermal mass to the building, significantly  reducing energy consumption. Trees planted along the east edge of  the campus will complement the Bloch Building, and at their  maturity they will continue to accent rather than obscure the lenses.  Plantings also will be integrated into the south end of the campus,  where the landscape descends into a more naturalistic style setting.

                                    | glass, steel, reinforced concrete  The five “lenses” are made of a double layer glass assembly with  pressurized air cavity between the layers. The outer layer consists  of double interlocked glass plank with OKALUX translucent  insulation in-between. The inner layer is translucent laminated low  iron glass, with an acid etch finish. (More than 6,000 planks of ¼-  inch translucent, sandblasted U-profile channel glass form a double-  glass cavity; laminated acid-etched flat glass and clear flat glass).  The channel and laminated glass provide modified, diffused natural  light into the galleries and the clear glass offers open views of the  Sculpture Park at various points in the galleries and halls. Other flat  glass in the project, between the lenses, consists of several  configurations of insulated glass units, all made with low iron glass,  including configurations with low-e coatings, acid etched surfaces  and OKALUX insulation. Concrete slabs and Retaining walls, steel framing and steel trusses,  concrete slabs on metal deck comprise the structural envelope.
 Computer controlled screens within the cavity ensure the efficiency  and seasonal day lighting flexibility for the lenses.
 
 Floors in public areas are terrazzo with recycled glass  aggregate. Floors in Galleries is stained end-grain red oak block,  terrazzo and granite.
 
 Wall finishes in public areas is polished plaster. Wall  finishes in galleries is a level 5 finish gypsum board on vertical walls  and gypsum plaster on vaulting in the lenses.  Bases are pre-cast  terrazzo and stainless steel. Glass railings are acid etched low iron  glass. Metal railings and hardware are bead blasted Stainless Steel. Public elevator interior surfaces are translucent honeycomb panels  with bead blasted stainless steel hardware.
 
 Ceilings in public areas are acoustic plaster and in the  Galleries painted gypsum board. Perforated wood acoustic ceilings  are utilized in the larger meeting rooms.
 
 Lighting throughout the project is a custom designed  combination of indirect cove lighting, intermittent (‘stitch’) track  incandescent lighting and recessed linear fluorescent fixtures.  Lighting is designed to balance color and intensity between natural  light from the lenses and electric lighting, providing the Museum  with maximum flexibility and control throughout the project.

                                    |  Stormwater Management The Nelson-Atkins New Building has green roofs contiguous with the landscape, providing a natural storm water  system. Paved area is decreased by replacing ongrade parking with a below grade garage. There is no net  increase in the rate of quantity of stormwater run off from existing undeveloped condition.
 
 Indoor Environmental Quality
 For sustainability goals and artwork conservation, all materials, including paints, sealants, carpets and adhesives  have zero or very low-VOC emittance. IAQ is an important consideration for the museum’s collection as well as  the occupants’ comfort. In addition to strict ventilation and conditioning requirements during construction to  reduce the possibility of trapping trace amounts of VOC’s, the building will undergo a two step commissioning  process. After the initial commissioning has been complete, the filters will be changed and the building systems  will be re-commissioned and run for an extended period of time to flush out any remaining odors, traces of VOC’s,  or other irritants. Extensive temperature and humidity monitoring maintains thermal comfort and art conservation  conditions. More than 75% of spaces are daylit.
 
 Materials & Resources
 100% of shell/structure and 50% of non-shell/structure of existing building is maintained. The new building  terrazzo floor is specified with recycled glass aggregate. Gallery floors are of FSC-certified wood. Local concrete  plants provide precast and cast-in-place concrete which constitute more than 30% of the overall building  materials thus the environmental impact resulting from material transportation.
 
 Renewable Energy/Green Power
 Lens air cavities are conditioned with the building's exhaust air. Enthalpy wheels located in intake and exhaust air  paths reuse building energy.
 
 High Performance Building Systems
 Existing Central Plant is completely refitted with new energy efficient equipment serving both existing and new  buildings without a net increase over current existing building-only energy consumption. New Building and  retrofitted existing building systems use no CFC refrigerants, HCFC’s or Halons. HVAC systems will undergo a  comprehensive year-long commissioning and verification period to optimize performance.
 
 Energy Flows
 The combination of the High insulating Green roof and Below-grade construction with large thermal mass reduces  the energy needed to maintain the strict environmental criteria of the exhibition galleries. Five “lenses”  constructed of a double skin glass assembly provide maximum natural light allowable for art conservation while  minimizing heat gain in summer; and harnessing solar gain and reducing heat loss in winter. “Lens” assembly  consists of exterior layer of double plank glass with OKALUX translucent insulation, pressurized air cavity, sealed inner laminated glass layer. Garage is naturally lit by skylights, reducing daytime electrical consumption.
 
 Water Efficient Landscape
 Plant types and species are indigenous or adaptive to the local climate, and require minimum maintenance.
 
 Light Pollution Reduction
 Low level site lighting is provided entirely by spill from building's interior lighting.
 
 Landscape and Exterior Design/Heat Island Prevention
 Trees/bushes provide shading throughout the landscape for paths, terraces and vision glass areas. 50,000sf of  green (vegetated) roof (overall 12" thick) increases the insulation R value by 3 points and reduces stormwater  run-off. White membrane roofing of “lenses” reduces heat absorption. Deep canopies shade west-facing vision  glass. There is minimal heat island effect.
