The Wilmot Team analyzed the Let’s Move Nashville Transit Improvement Program in a triple bottom line framework. An economic impact analysis was completed and a number of community transportation benefits monetized to evaluate the impact of the program. The Team identified that the program would result in 3,859 jobs per year and would add nearly $4.8B in wealth to Davidson County during construction. In addition, a number of annual community benefits were identified that would occur upon completion of the program. These benefits included $43M in travel time savings, $7.2M in air quality benefits, $15.1M in health benefits, $15M in safety benefits, $1.1B in economic development and $7,808 saved in individual out-of-pocket costs.
MNAA Sustainability Plan
In 2016, Wilmot joined the Metro Nashville Airport Authority (MNAA) Sustainability team to complete a Sustainability Plan Update. Current Waste Management practices at the airport were evaluated using a 2012 MNAA sustainability study as a baseline. Wilmot found that BNA had nearly doubled their recycling rate since 2012, with 395 out of 2,872 tons of waste recycled between June 2016 and 2017. The Team used these findings to provide specific recommendations to the MNAA for further improvement. Additionally, Wilmot applied local knowledge to identify partnerships and sustainability strategies through state and local funding sources.
Music City Solar
With familiarity of the local solar energy sector, the Wilmot Team was selected to guide Nashville Electric Service through the TVA Distributed Solar Solutions application process. The Music City Solar project would allow for Davidson County rate payers to support and benefit from clean, renewable energy. After the application’s approval, Wilmot was asked to guide NES through planning the development of the solar farm and the associated financial and community solar business models. The Wilmot Team located a North Nashville brownfield site that had been a construction and demolition (C&D) landfill as a viable placement area, allowing for the land’s beneficial reuse. Once construction is completed, the solar farm is expected to generate approximately 2.8 million kilowatt-hours of electricity per year.
Clean Water Nashville
Wilmot has worked alongside Metro Water Services to eliminate the flow of sewage into the Cumberland River through the implementation of the Clean Water Nashville Project, a conglomeration of over 70 projects that began in 2012. Through green infrastructure measures that include Low Impact Development, the Wilmot Team created sustainability targets for each project that private developers could be expected to follow moving forward. Wilmot also developed a program for the profitable recycling and reuse of project construction waste materials - with a goal of 50% diversion of construction and demolition waste - and conducted site inspections to ensure their accordance with the established standards.
CHS Solar Assessment
Wilmot’s extensive experience in renewable technologies allowed for their effective determination of the most favorable sites for solar panels on four Community Health Systems properties to improve efficiency and reduce energy costs. Wilmot conducted an analysis that included system production, siting, and financing concerns. The analysis listed the most efficient and beneficial placement options for each property and provided financing program suggestions that could be utilized moving forward. The Team estimated the solar panels would generate 10,570,400 kWh based on the amount of sunlight specific to the areas of installation. The analysis also incorporated effects on building attractiveness and tree canopy, and sited areas for potential future expansion.
Centennial Park Master Plan
In 2008, the Centennial Park Master Plan was created by Mayor Karl Dean to revitalize the park in a showcase of culture, art, and history alongside a beautifully and sustainably designed horticultural landscape. To encourage and incorporate community collaboration, Wilmot was tasked with developing and conducting surveys, public meetings, data collection, survey analyses, and presentations to inform the design team and Committee on the desires of Davidson County residents. After gathering input from the Nashville community, the Team created an action plan that incorporated sustainable design and operations reflecting the desires of the community. Additionally, Wilmot created outreach programs including onsite education events and local school engagement to be applied after the Master Plan’s completion.
Lakewood Economic Impact Analysis
The Wilmot Team conducted a triple bottom line analysis of a $13.9M infrastructure renewal project for a storm water system in Lakewood, TN that quantified its social, environmental, and economic impacts. The analysis measured the project’s performance within a Low Impact Development scope and measured benefits that went beyond drainage, including beautification and traffic control. The infrastructure improvements were calculated to introduce $27.1M in economic activity, 159 community jobs, and support small business in Davidson County. The improvements enhanced efficiency in the system and were projected to be of great benefit to public health and community.
Central Waste Water Treatment Plan
With the goal of improving waste water treatment capacity while limiting the construction of new tankage, the Wilmot Team designed a sustainability plan that incorporated public parks, a greenway, green-infrastructure, and solar power into the expansion of the Central treatment plant. Wilmot engineers implemented these designs and tracked the resulting efficiency improvements. Annual savings resulting from the implementation of first-stage improvements was estimated to be $302,220 with a 460-kWh reduction in energy consumption while increasing peak secondary treatment capacity by 40%. These developments will not only save Metro Water Services money but will also enhance community mobility and livability in Nashville neighborhoods.
440 Greenway TIGER Grant Application
To demonstrate the offset of construction costs for the Nashville 440 Greenway trail, Wilmot conducted a benefit cost analysis study that summarized the capital costs and public benefits resulting from the implementation of the greenway, finding the benefit:cost ratio to be 7.7:1, or $308,333,763 in net benefit. This value was calculated based on the difference between the capital costs of the project and the monetized benefits to traveling time and quality, public health, recreation, safety, reduced auto use, and property value. This analysis was submitted as part of a DOT TIGER Grant application and subsequently received TIGER’s highest economic analysis rating in the review process.
Metro Water Energy Management Program
Nashville Metro Water Services created an Energy Management Program in 2012 to expand upon energy efficiency and savings gains made in years prior. Wilmot assisted in the planning and implementation of infrastructure and operational strategies that save money and energy, including a fine bubble aeration system and combined heat and power engine to generate electricity. These upgrades are already generating over $1M in year over year energy savings with another $1M projected. Wilmot also conducted an in-depth analysis of solar feasibility and created a bid package that includes solar arrays at multiple MWS facilities.
Brick Church Equalization Facility
As part of increased sustainability requirements by Metro Water Services, the Wilmot Team was chosen to address design and efficiency concerns of a new equalization tank and pump station. Wilmot successfully diverted large volumes of the 2,000 truckloads of excavated material to be reused onsite, saving MWS money and reducing associated transportation pollution. The aesthetics of this facility were a major concern due to its placement in a residential area. This was remediated by the Team’s reduction of the tank height and addition of a vegetative buffer. Numerous other innovative, low impact development strategies were applied to the project, including green infrastructure to reduce storm water runoff, use of native/non-invasive plants, and the ability to locate a public park on the site in the future.
West Park Equalization Basin
The Wilmot Team designed and tested plans for the West Park equalization tank, the first project to be completed in accordance with Clean Water Nashville requirements. The final plans produced by Wilmot allowed for the provisions of solar ready design, reforestation, rainwater collection, bio-swales, vegetated buffers, and 100% management of site storm water. A Triple Bottom Line analysis conducted by the Team found the environmental, social, and economic benefits of these park enhancements to be $36.6M, making the benefit:cost ratio nearly 2:1.
Music City Center
With the Nashville ordinance requiring all Metro buildings to attain LEED Silver Status, the construction of the Music City Center called for exceptional consulting experience in sustainable large-scale construction. Representing the contractor and owner throughout the three-year project, Wilmot helped both contractor and owner attain LEED points and identify green building opportunities for the project. With the Team’s attention to design and fixture selection, the project surpassed its goal of LEED Silver and was certified LEED Gold. Within its first year, the solar array reduced energy costs for the building by $23,630. In addition, LED lighting resulted in a 70% reduction in energy use, and low-flow water fixtures reduced water usage in the building by 49%.
In the construction of the Titans Stadium, Wilmot created a C&D debris reuse, recycling and disposal program from scratch that impacted all 850 members of the on-site crew. Through the efficient management of a $1 million-dollar waste stream, the project reclaimed and reused more material than any other U.S. project built before. Wilmot saved the project approximately $500,000 through efficient waste-handling methods.
Facing a unique public-private partnership to develop market rate housing city-owned land and a city mandate to achieve LEED Silver certification, SWH Residential hired Wilmot Inc to lead the green building effort at Terra House, a mixed-use project in Nashville's Rolling Mill Hill area.
Housing units were modeled and designed to save residents at least 20% on their monthly energy and water bills compared to conventional construction. Commercial spaces will be leased to local retailers to attract neighbors either walking or driving to the location. Wilmot recommended several high performance solutions including high efficiency lighting and a “green screen” on the garage façade. Terra House returned some of its development footprint for community green space. Lastly, Wilmot encouraged design elements and a marketing effort targeting the livability concerns of both families with young children and the Baby Boomer “renter by choice” market. Terra House achieved LEED Gold Certification in 2016 at no additional cost over the LEED Silver budget.
Fort Campbell Army Base
The Wilmot Team transformed Fort Campbell’s single waste stream into a sustainable, profitable, and effective recycling program by locating markets for materials and designing custom recommendations and protocols. The program incorporated the salvage, reuse, separation, and recycling of construction and demolition materials. At the conclusion of the project, Fort Campbell management was left with an 80-page Contractor Training Program that would teach contractors how to profit from construction debris in future projects.
Lipscomb University School of Nursing
Background Lipscomb University’s School of Nursing is its latest example of local leadership in sustainable design and construction. As part of a multiple-building master plan, the School of Nursing is pre-plumbed and pre-wired to use a district ground source heat pump refrigerant loop being developed below the building cluster. When all buildings in the cluster are constructed they will begin using the district loop.
Results Wilmot was hired to provide both Fundamental and Enhanced Commissioning to satisfy LEED prerequisites and credits and ensure proper operation of the building’s energy systems. Commissioning, the process of insuring equipment is installed and operates as designed, is a LEED requirement, but is a valuable step for any building. The U.S. Department of Energy’s Lawrence Berkeley National Laboratory has repeatedly documented the value of commissioning and retro-commissioning for improved building performance and rapid financial payback.
Chattanooga Housing Authority
Background Chattanooga Housing Authority initiated two LEED for Homes projects to replace dilapidated multi-family housing. The first project received 50% of its funding as an incentive grant to pursue Platinum certification. The second was developed by a for-profit affordable housing developer/operator with no incentive funding. Wilmot Inc.’s competitively priced proposal was chosen to facilitate achievement of basic LEED certification of this second project, Maple Hills Apartments.
Results Wilmot led an integrated project team through a design charrette, showing that LEED Silver was within easy reach. Wilmot was later asked to identify measures to reach Gold certification, all of which was achieved with less funding than budgeted. Wilmot’s most critical contribution was the discovery of critical design flaws that would have caused premature equipment failure, wasted energy, and negative impacts on resident health. Correction of the error not only prevented ongoing equipment performance issues and complaints, it also saved the project 80% of Wilmot’s fee in the form of reduced construction costs, not counting millions of kilowatts and equipment repairs saved over the life of the buildings.
5th & Main
As the sustainability expert on the project team, Wilmot was responsible for ensuring the sustainable construction of the condo in accordance with LEED standards as well as designing the project’s residential recycling program. The project effectively recycled or reused 75% of on-site waste, with the Team tracking and accounting for all materials throughout the course of their use. Consequently, 5th & Main became one of Nashville’s first registered LEED high-rise living developments.
Habitat for Humanity
Background Habitat for Humanity of Greater Nashville’s mission is to provide quality, affordable homes. One way Habitat achieves this mission is by using the LEED for Homes certification to provide healthy, durable homes with lower utility bills. Wilmot Inc was select to help reach higher levels of energy efficiency and LEED certification.
Results Wilmot’s team initially identified 11 LEED points that were not being claimed, facilitated Habitat’s early adoption of ENERGY STAR version 3.0, and made recommendations resulting in an additional 10% energy savings over the prior year's LEED homes (with the additional measures having a 7-year simple payback). Wilmot returned a Silver certification in record time to qualify Habitat for a Spring 2012 grant-funding deadline.
Wilmot was specifically hired to help the affiliate achieve Gold certification at minimal cost and to lead the development of the “next generation” of all-electric homes: those consuming 50% less energy than the 2004 International Energy Conservation Code requirement, without the use of photovoltaic panels. To this end, the Wilmot-led team has identified another 7 LEED points, available at no additional cost, to achieve Gold, and is writing a grant to pursue Passive House energy efficiency levels.

The Team focused on cost savings through waste management, utilizing recycled content and reusing building materials wherever possible, and energy efficiency, incorporating renewable energy sources in its construction. Opportunities for community involvement were maximized throughout the planning process as well, resulting in the incorporation of options for a Metro Parks soccer field and Greenway extension after the project’s completion.
Al Gore Residence
The Wilmot Team took on the challenge of retrofitting Al Gore’s Nashville residence, a large home built in the 1920s. Steps made to retrofit the home included the implementation of a solar roof; a 10,000-gallon storm water cistern; efficient appliances, infrastructure and windows; and the use of local, environmentally-friendly building materials, all while minimizing environmental impacts from the construction process. The improvements to the home resulted in a 50% energy reduction beyond current building codes, becoming the first LEED for Homes Retrofit in the US. The Gore residence achieved LEED Gold and was EarthCraft certified through the Southface Energy Institute.
David L. Lawrence Convention Center
The Wilmot Team designed, tested, and implemented a large-scale C&D debris-recycling program for the project, beginning with an in-depth analysis of the project’s waste streams. Provisions within the program such as the use of crushed concrete along a riverbank at the site resulted in significantly improved efficiency and savings. Wilmot’s successful intervention measures helped make the David L. Lawrence Center the first convention center in the world to attain a Gold LEED rating.
U.S. Armed Services
Balfour Beatty contacted Wilmot when they realized they had no reliable energy use data for the hundreds of U.S. military facilities they managed due to a lack of energy meters and data collection methods. Through Wilmot’s engineering support expertise, an analysis was conducted on energy usage and opportunities for improvement in the reporting process. As a result, Balfour Beatty received an intensive consumption analysis based on the year and square footage of each building, climate, number of occupants, facility type, and certifications. This analysis resulted in significantly improved reporting when Balfour Beatty faced an ISO audit shortly thereafter.
1420 Shelby Avenue
The Wilmot Team facilitated multiple LEED Platinum certifications for Shelby Ave homes that had been restricted by storm water and public easements. Focusing on sustainability while keeping appearance in mind, the Team maximized efficiency through insulation and durable, locally sourced materials. Features such as a rain garden, a heat-deflecting roof and windows, insulated walls, and LED lighting contributed to the home’s unique and sustainable design.
Metro Water Services Solar
A significant aspect of Metro Water Services Energy Management Plan was its incorporation of solar energy. By taking an inventory of MWS facilities and evaluating them for energy use and renewable energy savings potential, Wilmot provided MWS with a feasibility study that incorporated the costs and benefits of various location and system options for onsite solar installations. With the full consideration of capital costs and energy savings, Wilmot was able to create a bid package that includes solar arrays at multiple MWS facilities. Our innovative behind the meter, third party ownership model is projected to have a strong return on investment.
Old Dominion Freight Lines
Old Dominion, a leading U.S. logistics provider, chose Wilmot to analyze their energy usage and locate opportunities for optimization and efficiency across their nationwide portfolio of distribution centers. The Wilmot Team constructed a protocol to streamline energy management and reporting for the company based on an in-depth space-function and energy use analysis. The Team also successfully located opportunities for solar in nationwide locations.
Centennial Park SITES Certification
Wilmot worked with the design and construction team to create a plan for the ecological restoration of Centennial Park while also focusing on sourcing materials locally and reclaiming materials used in construction. This ten-year plan includes a water reuse system that allowed for storm water to be recycled within the sewage system before its filtration through the wetlands and use in site irrigation and lake recharge. The restoration of the aquatic ecosystem through the management of soil and native plants was also incorporated into the plan. With the sustainable restoration of Lake Watauga and Cockrill Spring in Centennial Park, Metro Nashville Parks was among the first 50 projects in the nation to achieve SITES certification.
Al Gore Office
When Al Gore was building out his Green Hills office, he wanted to set a high standard for a green office. Wilmot was chosen to work with the General Contractor to ensure that the project achieved LEED Platinum (Commercial Interiors).
The project team set a goal of 95% construction recycling, so Wilmot wrote a detailed plan for how to manage every anticipated material. Wilmot helped train the contracting team and on-site subcontractors to reach maximum recycling rates. Containers for each material type were put in the work area so that the contractors could separate the materials at the source. Acceptance was so high that when the on-site workers found a material that had not been accounted for, they created their own container for that material. In the end, the project achieved a remarkable 97% recycling rate, earning 3 LEED points. Along with recycled and regional materials, the office is equipped with state of the art technologies to control natural light and glare. All of these efforts led to a LEED Platinum certification, and the highest number of LEED points earned on a project at the time.
Advisory Board Company
The Advisory Board Company is a research, technology and consulting firm specializing in improving performance in healthcare and higher education. When they built out a new office in Nashville, they knew it needed to be a place that would be healthy and productive for employees, so they chose to pursue LEED CI certification.
Wilmot Inc. assisted General Contractor DWC in documenting compliance with LEED procedures. The project team excelled in selecting building materials that are regionally sourced, and have low toxins. These material selections, along with DWC’s construction practices, produced an office space that will have clean air and a healthy, productive environment for employees.
Columbia State Community College
A waste audit and analysis conducted by Wilmot was utilized to create an effective recycling program on Columbia State’s campus and to distribute clearly-labeled recycling bins where needed on campus. Through this integrated waste stream analysis, over 75% of Columbia State’s material stream was found to be recyclable. In order to further establish the program, the Team conducted staff and student interviews campus sustainability leaders to head future waste reduction and recycling efforts.
