Runci is a Mechanical Design Engineer II 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.
