One22One

Project Statement

One22One boasts one of the best addresses in Nashville, sitting directly on Broadway where three of the city’s most well-known neighborhoods - The Gulch, Midtown and Downtown - connect. Formerly the home of an auto repair shop, One22One is located at the western gateway to downtown Nashville from Interstate 65.

While well-situated, the site with limited area and with limited potential height, presented several challenges to the standard market-based model for office development. The small site and limited buildable volume offered little flexibility in form finding. The concept employs a façade faceting strategy that minimizes sculptural form while maximizing the impact of the glassy façade’s reflectivity. The faceted glazing offers a constantly changing façade to the public that stands apart from the more conventional nearby buildings – all of which are confined by similar circumstances of small sites and capped height resulting in a uniformity of scale.

One22One balances market-driven needs with an ethic that promotes sustainability, wellness and alternative modes of transportation including pedestrians and cyclists. Various design strategies work to transform the user experience from one of constraint to something more open, airy and expansive.

Framework for Design Excellence Narrative

**#Design For Integration**

 

Client Impact Statement

The client acquired a prime but constrained piece of real estate and sought to develop a Class A office tower to serve Nashville's booming market and to capitalize on the growing connection between the city's downtown and midtown districts.  The project offers a highly desirable "work" component to one of Nashville's growing Live-Work-Play neighborhoods.

 

Statement of Design Excellence

Occupying a site previously fronted by an active surface parking lot and auto service center, the new project creates an urban, pedestrian-scaled streetscape filling in another piece of the puzzle as downtown Nashville transitions from a car-centric to pedestrian-centric neighborhood.  Occupants have access to a landscaped amenity terrace for fresh air and sunlight.

 

**#Design For Equitable Communities**

 

Community Engagement

Community engagement made up a key part of the zoning entitlements effort resulting in universal support among neighbors.

 

Community Benefit

The project improved street frontage prioritizes people over cars in what has been a dangerous neighborhood for pedestrians and cyclists.

 

Transportation Choice Equity

Walk Score = 96, Transit Score = 70, Bike Score 72. Program includes bike storage and repair facilities as well as EV charging stations. In addition to above, the project provides direct access to multiple bus lines.

 

 

**#Design For Ecosystems**

 

Common App for Design Excellence Prompts/Information:

Design for Water Narrative

Low flow fixtures and reuse of condensate reduces potable water usage.

 

**#Design For Economy**

 

Common App for Design Excellence Information:

Building Efficiency / right sizing: Withheld

Does the project address issues of affordability? No

Does the project reduce built area by designing spaces for multiple purposes? Yes

Cost per Square Foot: Withheld

 

**#Design For Energy**

 

Common App for Design Excellence Prompts/Information:

Energy Code that the project was built to? IECC 2012

Baseline & Code

Benchmark EUI: 89 kBTU/sf/yr  \*\*\*Generated based on building type

Estimated EUI based on Code: 67 kBTU/sf/yr  \*\*\*Generated based on local energy code

 

Energy Performance

How are you reporting energy performance for this award submission? Modeled Energy

EUI Gross (Energy Consumed from all on-site sources): 63 kBTU/sf/yr

EUI offset from onsite renewables: 0 kBTU/sf/yr

EUI Net (Gross EUI minus energy offset from on-site renewables): 63 kBTU/sf/yr

Predicted reduction from Benchmark: 29%

Does the project meet the 2030 Challenge: No

 

Energy Conservation Process & Strategies

What type of energy model was performed? Design Energy Model

Was the energy model used to inform decisions during design? Yes

Did the project follow prescriptive performance to meet energy code? No

 

Design for Energy Narrative

Energy model was used to inform selection of glazing specifications.

 

**#Design For Wellbeing**

 

Common App for Design Excellence Prompts/Information:

Do regularly occupied spaces have operable windows? No

Were glazing strategies studies to optimize daylight against excess heat gain? Yes

Is indoor air filtered with MERV 13 or better? Yes

Was ventilation, either natural or mechanical, optimized for occupant health? Yes

Is potable water treated or filtered prior to human consumption? Yes

Was a “Chemicals of Concerns” list used to inform material selection? Yes.

 

Design for Wellbeing Narrative

Materials containing known toxic ingredients were avoided in order to optimize indoor air quality.  A generous landscaped terrace provides occupants access to fresh air and daylight.

 

**#Design For Resources**

 

Common App for Design Excellence Prompts/Information:

Was wood used on this project FSC Certified? Yes

Were steps taken to substantially reduce material or embodied carbon? Yes

Were concrete mixtures optimized for carbon reduction? Yes

Did the project incorporate existing structure or infrastructure? No

 

Design for Resources Narrative

Low carbon concrete was employed.

 

**#Design For Change**

 

Common App for Design Excellence Prompts/Information:

What is the designed lifespan of the building? 100yrs

Was the building designed for disassembly? No

Is the building designed to accept future clean grid power? No

Has the design made accommodations for projected climatic change? No

 

Design for Change Narrative

An unusual modified conventional concrete structural system allowed foe reduced depth of structure and increased flexibility in integrating tenant utilities.  This allowed for higher vision glazing and more access to sunlight.
