[ ] ACTIVATE EAST TVA TOWER The conceptual basis for this project is to activate the existing, static TVA complex through dynamic strategies which promote TVA’s goals for innovation in high performance design and increased community interaction. Christina Lulich, Ryan Stechmann, & Paul Bamson | James Rose & Keith Boswell | Integration Studio 471 ACTIVATE [EAST TVA TOWER] Measure 1: Design & Innovation The location of the site within downtown Knoxville at the ter- minus of Market Square presents opportunities for views, com- munity interaction, and improved efficiency through increased downtown density. The conceptual basis for this design is to activate the plaza, interior spaces and facade. Knoxville has not yet made a significant appearance on the sustainable design scene, but a retrofit design of the iconic TVA towers could be- come a model for future design in that direction. Thus, the goal is to maximize energy performance primarily on the facade level but also through stormwater collection, greywater reuse, and rooftop solar power collection. Through an innovative ap- proach to existing photovoltaic-operated louver technology, we have designed a dynamic facade which minimizes solar heat gain, maximizes diffused light and city views, controls fresh air circulation for the HVAC system, and also aesthetically activates downtown Knoxville. Measure 2: Regional/Community Design The primary regional response is in the nature of the project itself: bringing residential into downtown. Knox County’s urban sprawl hinders its efficiency. According to the East Tennessee Index, average travel time to work for Knox County residents is 21 minutes each way. Expense, time, and harmful emissions caused by this distance can be decreased by encouraging resi- dents to live and work in the same vicinity. No additional park- ing is provided in the design, which encourages transportation via foot, bike, or Knox Area Transit. Market Square is a space culturally significant to Knox County, and the current TVA tow- ers and plaza terminate the lively square in a stale and reclu- sive manner. This design strives to transform the space into an extension of the square, activating it with shops and outdoor gathering spaces. Additionally, an under-used resource particu- lar to our climate is rainwater. Climate Zone 4 is particularly wet, with the Tennessee River watershed receiving around 51 inches of rain per year. By using low impact development strategies such as bioswales and permeable pavers, this proposal offsets the demand for offsite water significantly. Measure 3: Land Use & Site Ecology Pollution from water runoff damages ecosystems and contami- nates limited freshwater. Our strategy for low impact develop- ment is a series of bioswales with vegetation that can with- stand extreme moisture. These gardens collect the stormwater onsite, minimize runoff, and support a habitat appropriate for birds and butterflies. Through the combination of planted plaza space, green roofs, and permeable paving material on the walk- able surfaces, permeable material covers 70% of our site. The increase in planted material helps to filter out pollution in the air in the most densely-occupied outdoor spaces on-site. The design increases both public park space and downtown den- sity. Also, by transforming a currently unoccupied building into leasable apartments, density will increase dramatically during the day and night. Measure 4: Bioclimatic Design Initial sun pattern analysis revealed that the areas of concern re- garding solar heat gain are the entire south facade and most of the west facade. Following this study, we developed a modular system which responds to heat, light and views while creating a visually active, dynamic building. On the modules affected by heat gain, almost all of the glazing is shaded by self-adjusting photovoltaic louvers which power themselves with renewable energy. No excess energy is returned to the building or grid, so the modules act alone. Randomizing these modules on the fa- cade dictated room placement within the floor plans, although we strove for consistency where possible. We determined that solar gain on the east and north facades was insignificant, so we developed a similar system of modules without louvers for those locations and for the commercial levels. Measure 5: Light & Air 6” window louvers are spaced 8” apart in the view area to al- low both maximum viewing and shading capacity. The louver angles can be overridden within the residential units for maxi- mum user comfort. Residential levels are limited to the upper 8 floors, maximizing views of the city and mountains beyond. A mixture of floor-to-ceiling and sill-to-ceiling glazing and a 3-lev- el north-west atrium bring a vast amount of diffused light into the office level spaces. The layout for these levels is open with conference rooms “floating” within spaces, allowing maximum natural light to penetrate throughout the interior. We chose to use the existing four-pipe system with fan coil units. Fresh-air handling, stale air exhaust, and heat recovery are all handled at the facade level. This system is ideal because it reduces duc- twork, allows for maximum personal control, and is affordable. 10’ vestibules with pollutant-collecting mats occur at all main building entrances for improved indoor air quality. Measure 6: Water Cycle Groundwater depletion in the U.S. is becoming more and more of an issue as water is pumped faster than it can be replaced and as irrigation and runoff pollutants contaminate the water. By re- cycling the stormwater onsite, runoff pollution and demand for decreasing groundwater is reduced. Bioswales direct water into the collection system. Most of the hardscape onsite is perme- able, and rainwater falling on both the hardscape and planted material is filtered into the ground, collected by pipes within a layer of gravel, and stored in a cistern in the service area of the building. This is also where greywater is collected and treated. In this way we will offset groundwater demand, reducing cost and increasing self-sufficiency of our site. Measure 7: Energy Flows & Energy Future The louvered facade modules have a low shading coefficient, reducing heat gain and uneven building temperatures. We maintained our photovoltaic theme by supporting 751 Sanyo Hit Bifacial solar panels on the roof, producing 146kw at peak. This is 3% of the current building energy demand. We expect to see a change in energy demand due to the occupancy change, but the solar panels will significantly offset this demand. Measure 8: Materials & Construction The project fundamentally supports material reuse and recy- cling by maintaining existing building structure. The facade modules are prefabricated which reduces waste, garbage re- moval costs, weather damage to materials, theft, and on-site la- bor costs. The system will function more effectively with manu- factured precision, and onsite construction will be quicker as a result, minimizing the negative effects of creating a construc- tion site so near to Market Square. The modules are made of an aluminum tube frame to keep weight low. Each residential level has a trash chute with recycling, and most floors have an addi- tional recycling center in the public seating space. Measure 9: Long Life, Loose Fit The East TVA tower is currently unoccupied because there is a low demand for office space in downtown Knoxville, an atypical trend in most cities. There is, however, a high demand for resi- dential, and we expect that with the increase in downtown resi- dents, there will be an increase in office space demand. Thus, we have left two levels of our design unoccupied for future de- velopment and lease, allowing program adaptability. The two MEP office levels are designed with maximum open space for flexibility. Additionally, because the facade modules are the same dimensions, they could be detached and rearranged if necessary. Measure 10: Collective Wisdom and Feedback Loops In Rhino and Revit, we evaluated the effects of sunlight on our facade, ultimately achieving the dynamic appearance and ef- ficiency we envisioned. We calculated the energy output and loss, and we expect our systems to be actively monitored and fine-tuned following construction to measure efficiency.

We want to activate the Plaza with an occupiable circu- lation element which connects Wall Avenue and Market Square to Summit Hill Drive. A grassy terrace accompanies the primary accessible ramp between the towers, provid- ing public green space. PRIMARY ENTRANCES [A] Residential [B] MEP Office [C] West TVA Tower [1] TERRACED PARK SPACE This will serve as the primary access to Summit Hill Drive. Alongside the accessible ramp is an occupiable green stair. [2] LOW IMPACT DEVELOPMENT Plantings in the center of the lower plaza collect rainwa- ter from runoff. This is held in a cistern for use within the building. [3] RETAIL ZONE & GREEN ROOFS The lower level retail zone extends two bays beyond the current extents of the building. This brings the building to the sidewalk, increasing movement on Market Square level. This occurs in front of both towers. All roofs are oc- cupiable with permeable paving or groundcover to collect rainwater. The green space also reduces heat gain and re- flectivity. [4] SANYO HIT BIFACIAL SOLAR PANELS 751 solar panels cover the upper roof and shade the oc- cupiable roof deck. These panels collect light from above and underneath to catch reflected light for maximum effi- ciency. The combined energy collected at peak powers 3% of the current building’s energy demand.

Offices are either concentrated in the tighter areas or floating within the open areas. An atrium in the northwest corner brings in additional diffuse light and unites the two office levels. FLOOR 1 | MEP OFFICE The two MEP office levels occur above the main entrance. The Market Square level retail provides an occupiable green roof for outdoor meetings for MEP employees. RETROFIT PROGRAM The lowest two levels create a retail zone, activat- ing the plaza levels. An MEP firm occupies the next two levels. Office space demand in Knoxville is currently low but is high in many other cities. We expect with the increase in density inevitable in a growing city, particularly due to the conversion of most of the tower to residential, that office space demand will increase. Therefore, we have left two levels unprogrammed for future development as needed. This helps to maintain a long-life, loose-fit mentality. The remaining eight levels are residen- tial units. The first four contain double-height mi- cro units, while the upper four contain larger units. The lowest two levels have amenities in the core, and the upper 6 have seating space and atrium. 1/16” = 1’ 0 8’ 4’ 16’ 32’ 1/16” = 1’ 0 8’ 4’ 16’ 32’ 2-HOUR FIRE-RATED WALL 2-HOUR FIRE-RATED WALL 1-HOUR FIRE-RATED WALL 1-HOUR FIRE-RATED WALL PROGRAM [1] Trash and Recycling Chute [2] Mechanical Room [3] Printing Center [4] Studio [5] Workout Facility [6] Yoga Room [7] Storage LEVEL 6 AMENITIES [1] Trash and Recycling Chute [2] Mechanical Room [3] Multipurpose Meeting Space [4] Studio [5] Game and TV Room [6] Movie Room [7] Storage *Amenities occur in same location each level PROGRAM [1] Elevator [1a] Residential Elevator [1b] MEP Elevator [2] Mechanical Duct Shaft [3] Stair [4] Electrical [5] Restroom [6] Trash & Recycling [7] Vending [8] Janitor’s Closet [9] Mail Room [10] Atrium FLOOR 5 (5-8 typ.) Floor 5 is the first level of resi- dential program. Floors 5-6 have amenities for all the units, while the upper 6 floors have an atrium and floor amenities. Floors 5-8 contain two unit plans unique from the upper levels: double- height micro units [E] and small one-bedrooms [D]. The double height apartments provide a unique layout within small square footage, higher ceiling heights, and increased view glaz- ing area. These help to provide a variety of unit types to meet dif- ferent housing needs. WALKABLE DOWNTOWN Our site is located in the center of downtown Knoxville. Local ame- nities are walkable and parking lots are available nearby. DOWNTOWN KNOXVILLE & MARKET SQUARE CORE TRANSFORMATION 7 elevators are unnecessary for the new program we are proposing, and in order to meet code for egress stair, we needed to relocate the northeast stair into the northeast mechanical duct shaft. We consoli- dated the core to only the most necessary elements, leaving one elevator for the MEP Office levels and three for residential. Without the need for vending and restrooms on all levels, we had space for an atri- um. RESIDENTIAL UNITS We designed units with maximum openness for day- lighting and views. Most bedrooms have windows and all windows are above adjacent buildings, so ev- ery unit has views over Knoxville. The unit sizes range from micro unit to large 2-bedroom.
