The Apadana Group

The Apadana Group is a collection of independent companies, owned or co-owned by Apadana founders, whose collective mission is to address the broad needs of organizations seeking to expand their environmental responsibility through either investments in their building operations or investments in the generation of low/no-carbon renewable energy solutions.

A common denominator across all of our operating companies is the need for engineering resources.

Since forming Apadana in 2013 , our primary engineering focus has been on increasing the energy efficiency of buildings through lighting re-design and retrofit using LED and advanced digital control technology. Our success is reflected as a 5-time winner of Xcel Energy Efficiency Partner Award.


Having reduced building energy consumption, the next logical step was to enable our clients to generate their own renewable energy. We accomplished this with formation of Apadana Solar Technologies, which functions as an EPC (engineer, procure and construct) that designs and may install solar PV systems for complex commercial/industrial, utility-scale and community solar garden customers.


Sharing electrical engineers with Apadana and Apadana Solar, we launched US Luminaire, an LED lighting product company. Our electrical engineers provided light and driver specifications used to develop proprietary commercial fixtures. The team also supported ATEK Distribution, an electrical equipment wholesaler with a design/sourcing capability for large-scale switchgear and other complex electrical components.


Most recently, we added structural, mechanical and process engineering talent to the engineering team as part of our acquisition of Clark Technology, a waste-water recovery/reuse and renewable waste-to-energy (biogas) design-build company.


Having a strong cross-company engineering team has become the foundation for Apadana Engineering services, that provides clients with renewable energy engineering and project support. Engineers employed across these companies provide the core staff for our “blended workforce” model that ensures we have the right skill-set for the project we undertake.


Our reputation is built around our ability to engineer solutions for the most difficult electrical challenges.


Blended Workforce Model

Perhaps you’ve heard the term ‘blended workforce,’ which can also be called a variety of things, such as on-demand or variable staffing models. These types of workforces combine a core staff that is augmented by independent consultants and/or strategic partners to provide specialized capabilities that match the exact needs for a specific project. Apadana has embraced this concept for its engineering team. We assign an experienced staff engineer who acts as our engineering project manager and then determines the skills required for the success of the project. Once defined, the project manager forms a project-specific engineering team using Apadana staff resources supplemented by independent consultants and strategic partner firms whose skills have been fully vetted.

Blended Workforce Benefits
  • Perfect match between engineering skills and project requirements.

  • Ability to quickly scale up, eliminating backlogs and ensuring on-time project completion.

  • Core staff provides continuity and can expand their skill-set through interface with skilled third-party engineers.

  • Lower project costs by reducing overhead associated with underutilized staff, whose cost is typically passed along to each customer as part of the project cost

Engineering Project Management

Engineering Project Management evaluates the project to define the specific set of engineering competencies required to complete the project engineering requirements. The EPM then identifies individuals from available resources to create a project engineering team that the EPM manages through the life of the engineering project. Team management includes task assignments, scheduling, data assembly, report generation, and most importantly, client interface. The EPM is also responsible for evaluation of team performance which may include disqualification of a consultant or individual within a strategic partner whose contribution is not meeting Apadana qualify standards.

Strategic Partnerships

Successful strategic partnerships are complex. They require extensive pre-planning to build a strong foundation that supports each partner through the challenges they will face. And they require a longterm commitment from each partner. Apadana has thoroughly vetted and selectively engaged market leaders in their respective engineering field as a strategic partner. C-level relationships have been established and frequent communication helps to evaluate project performance from both sides of the partnership. Strategic partnerships are in place with firms in the civil, large-scale electric power, process control, HVAC and industrial engineering disciplines. When teamed with a strategic partner, the scope of engineering projects Apadana is capable of performing is virtually limitless.

Strategic Partners
  • Are aligned at the C-Level to ensure that each partner is fully committed to the relationship and is willing to invest the resources required for success.
  • Have complementary not competing core competencies.
  • Provide access to business opportunities not otherwise available without the engagement of the strategic partner.
  • Are exclusive in their respective areas of expertise and cooperation which can prevent concerns over potential competition that can limit commitment to a project’s success.

Engineering Capabilities

Over the past 20 years, not only have lighting technologies, lamp sources, and controls improved considerably, but energy codes and green building standards have also driven what we consider to be efficient. We no longer simply lay out 2 x 4-ft, 4-lamp troffers on an 8 x 10-ft grid spacing. Lighting designers, architects, and engineers work together to balance aesthetics, lighting quality, and energy for a better total lighting solution that performs well and complies with energy codes. We do not have to sacrifice the quality of lighting designs or reduce lighting levels just to meet energy codes. Apadana designers and engineers work with each customer (architect, building owner) to specify the optimum lighting package that meets their building/operational requirements.


  • Facility lighting audits

  • Fixture cross and value engineering

  • Energy consumption studies

  • Photometric assessments and analysis

  • Occupancy, daylight, and time-based controls

  • Lighting code compliance

  • PoE (power over ethernet) lighting design

  • Human-centric lighting designs

Engineering Capabilities

Apadana offers comprehensive waste-to-energy (bio-gas) engineering services through Clark Technology. The company applies its deep experience in bio-digesters gained with its patented process to design, engineer, construct , install and commission systems that meet each customer’s specific needs.

Breath of capabilities include preliminary plant design, process design, facility design, material sourcing/procurement, facility construction oversight (EPC), feedstock sourcing and contracting, offtake contracting, plant commissioning, consumable supplies, operations and maintenance.

When applicable, the bio-digester will be integrated with Clark’s waste-water recovery system that adds another level of environmental responsibility by minimizing the use of external water resources.



One of the fastest growing trends in the photovoltaic market is the use of carports as a means to support a PV system. An ideal location to build solar carports is anywhere with a parking lot and

limited shading from trees and tall buildings. Design and installation of carport solar systems can be challenging, especially when installed on the top floor of multi-story parking garages. Apadana

Solar recently completed a community solar garden carport which has received rave reviews.

Project: Community Solar Garden on Minnesota Dept of Transportation Ramp A Location: Minneapolis, MN Power: 1.37MW

Description: This 1.37MW solar carport canopy in downtown Minneapolis was built on a custom truss system supported by the existing structural columns of MnDOT’s Ramp A. The arrays have a shallow 2-degree pitch towards the center of the Ramp to manage water drainage towards the existing storm drains and also to avoid the potential for snow and ice sliding onto pedestrians or vehicles during the winter. The array consists of 3,760 robust 365 watt monocrystalline 72-cell modules produced by HT-SAAE. Chint Power System inverters feed back to the grid through custom low voltage switchgear, a substation step-up transformer, and custom medium-voltage switchgear located at grade. An AlsoEnergy data acquisition system is used for detailed monitoring and performance tracking.


Solar systems on commercial and industrial buildings are typically installed on a flat roof. In many cases, efficiently positioning solar panels and associated racking around established obstructions is one of the solar designer’s greatest challenges.


Project: Lifetime Fitness Rooftop Power System Location: Plainsboro, NJ Power: 362kW

Description: This 362kW behind the meter array consists of 1,066 NSP 340 watt, 72 cell monocrystalline solar modules. A Solar Edge inverter with optimizers was used to maximize the production efficiency of the array. A ballasted racking system from DCE was installed at 10° to maximize the number of modules installed in the limited roof space.


Solar systems on commercial and industrial buildings are typically installed on a flat roof. In many cases, efficiently positioning solar panels and associated racking around established obstructions is one of the solar designer’s greatest challenges.


The search for open land capable of hosting a solar garden is often a challenge, pitting farmers vs. small towns who fear losing the aesthetic appeal of their community. Nevertheless, community solar gardens have become a staple across the country as people seeking renewable energy but unable to install a system themselves (i.e. renters) subscribe to their power.


Project: Cooperative Energy Futures Community Solar Garden Location: Faribault, MN Power: 1.31MW

Description: This 1.31MW solar installation is directly connected to the Xcel Energy grid. Power is generated via 4,030 325 watt Yingli monocrystalline 72 cell solar modules. Each module is attached to a helical (pile) post mounted rack at 30° for optimum angular efficiency in Minnesota, space considerations, and snow shedding. Modules are integrated with 60kW Chint Power System inverters and an AlsoEnergy data acquisition system.


This unique member-owned solar garden serves lowincome and disadvantaged electric power subscribers.
