Michael Scorrano, PE

Managing Director and Founder

Michael is the Managing Director and Founder of EN-POWER GROUP. With over 25 years of experience in both the generation and end-use sides of the energy industry, Michael founded EN-POWER GROUP with the vision of developing an engineering firm that does energy management “better”. With that simple vision, EN-POWER GROUP evolved into an engineering firm that designs, develops, and delivers comprehensive, integrated, and practical energy solutions from concept to completion.

Michael’s engineering career began at Westinghouse Electric in power generation, where he managed the development of large-scale central station and combined‑cycle power generation plants ranging from 100 MW to 1,000+ MW throughout the Middle East, Asia, and the Americas. After relocating back to New York, his career transitioned to working directly with large end-users on energy reduction, onsite generation, district steam, microgrids, and renewables at Trigen Energy, eventually leading him to work in the demand-side energy efficiency sector as Director of Business Development at Con Edison Solutions. There his responsibilities included developing companywide strategic plans to accelerate business growth in the commercial, educational, and healthcare sectors, overseeing energy efficiency projects, project financing, commodities trading, and energy purchasing. These extensive and diverse experiences in the energy space empowered Michael to create a company that applies practical solutions to complex energy needs to maximize savings and reduce environmental impacts for its customers.

Runci Ma, PE

Senior Mechanical Engineer

Runci is a Senior Mechanical Engineer at EN-POWER with a passion for designing energy efficient building systems that reduce the impact of carbon emissions on our communities. With over 7-years’ experience in the building energy industry, Runci is an expert in designing and energy modeling central plant upgrades at large facilities and has worked with major NYC agencies including NYCHA, NYCSCA, NYCDDC, DASNY, and NYNJ Port Authority. She deftly navigates code requirements (Building, Plumbing, Fire, Mechanical, Energy Conservation) along with ASHRAE and SMACNA standards to prepare drawings and other materials for obtaining appropriate work permits, ensuring all steps of project design and implementation are seamless. Runci’s mechanical design experience gives her a special perspective to her energy modeling work, since who’s better to model a building system than the person who knows how to design them?

Designing diverse engineering projects ranging from Existing Buildings to New Construction with a focus on energy and carbon

One of Runci’s projects is the heating and cooling plant designs and installation at a 96-unit, 15-story luxury condominium property in Brooklyn, NY. The Board was interested in reducing the building’s carbon emissions and associated NYC Local Law 97 carbon penalties, and wanted to review the replacement options for their aged chiller plant. A thorough assessment was especially important as the gas-fired chiller provided not only cooling for the building but also heating and domestic hot water (DHW), a very inefficient method. After conducting a detailed site assessment, Runci designed and helped oversee the installation of their new systems that included: modular electric chillers for cooling; dedicated, high-efficiency modular boilers for heating and DHW; and an integrated Building Management System (BMS) for centralized and remote control of the new equipment for deep energy and carbon savings.

Another of Runci’s projects is the new construction of the National Black Theatre, a 240,000 sqft mixed-use residential, retail, and event space that will be the new home for the Theatre in Harlem. To support their energy and sustainability goals, Runci is performing the facility’s detailed energy modeling and helping develop green roof designs to comply with NYC Local Law 92 and 94 requirements.

Nikita Gupta, PE

Engineering Project Manager PE

Nikita is an Engineering Project Manager at EN-POWER GROUP interested in exploring innovative and effective design solutions to meet client needs. She has a passion for optimizing and developing energy models to streamline and improve analysis of building systems. Nikita has conducted energy audits, retro-commissioning studies, and energy reduction analyses on HVAC systems for over fifty (50) large commercial and multifamily buildings, making her well equipped to review designs and optimize building mechanical and distribution systems.

A cooling system upgrade saves a Manhattan multifamily 70 metric tons of carbon annually and receives $50,000 rebates 

One of Nikita’s projects is the cooling system replacement at a 155-unit, 15-story cooperative building in Manhattan, NY. The building’s cooling tower and electric screw chiller both suffered from major performance issues: the cooling tower fan constantly short-cycled (i.e., turned off and on) leading to resident noise complaints and inefficient operation, and the chiller’s performance and reliability had greatly degraded. The chiller’s unreliability was exacerbated due to the fact a single chiller unit was carrying the cooling load of the entire building – meaning when the chiller broke down, residents were left completely without cooling.

As part of the cooling system upgrade, Nikita chose a modular electric chiller because it could provide three critical things: redundancy in case of equipment failure, significantly increased energy efficiency, and minimal on-site construction as it could be installed in pieces rather than requiring walls to be torn down. For the new cooling tower design, she selected high efficiency motors and variable frequency drives (VFDs) to further reduce energy use. In addition, she was able to incorporate both new systems into the site’s existing Building Management System (BMS) to increase ease of operation and reduce client costs. Nikita’s work is helping the building reduce its energy use by nearly 100,000 kWh and its carbon footprint by 70 metric tons annually, while also securing over $50,000 in funding from Con Edison’s Multifamily Energy Efficiency Program (MFEEP).

Jeffrey Heller

Managing Energy Auditor

Jeffrey is a Managing Energy Auditor at EN-POWER GROUP who helps buildings navigate to a more energy efficient future. His passion for the energy industry began while working on a self-sustained dairy farm primarily powered by a solar photovoltaic (PV) system, inspiring him to pursue a career in sustainability. At EN-POWER, Jeff has conducted energy audits, retro-commissioning studies, capital needs assessments, integrated physical needs assessments, and project management services for over seventy (70) large commercial and multifamily buildings with a wide range of mechanical systems, making him well equipped to help clients strategize building improvements and associated capital planning.

How an Energy Auditor helps a 1.6-million sqft Mitchell-Lama complex strategize their capital planning and save $850,000 annually

A recent project Jeff led and completed was an Integrated Physical Needs Assessment (IPNA) for Linden Plaza Housing Complex, a 1.6-million square foot Mitchell-Lama development for moderate-income families. The Brooklyn complex consists of five (5) large buildings and 32 townhouses, with 1,525 total units. The building mechanical systems and physical construction needed extensive renovation, prompting the property managers to commission an IPNA study to help evaluate their options and opportunities for improvement. Importantly, the IPNA report would be used as a tool to help receive funding from the New York City Department of Housing Preservation and Development (NYC HPD), and had to meet rigorous standards and specific agency requirements.

Jeff and his team of engineers and architects identified 17 major capital improvement upgrades that would save the facility over $850,000 annually in utility costs. Measures were diverse and included installation of new central plant heating boilers, major repair of the vacuum steam distribution system, elevator modernization, roof replacement, and overhauling the exhaust ventilation system. Jeff’s analysis also included a detailed 15-year financial projection that outlined projected utility costs, construction costs and paybacks, repair schedules, local law compliance needs, and incentives and rebates that could provide financial assistance. Currently Jeff is helping the facility strategize their capital planning and select a final package of holistic measures to implement for deep energy savings.
