Meet the Team

Elizabeth Repin – Principal

LEED AP BD+C, IREE, CxA, Investor Confidence Developer

Elizabeth received her LEED accreditation status in 2006. She founded Green Living, LLC, an Engineering team that provides “A to Z” Sustainability Consulting to include Pandemic Responsive Building Guidelines for more than 25M sqft of Certified Space. Elizabeth believes that a LEED hands approach (project management versus consulting) is crucial in the ever-changing guidelines required by all Certifications, including LEED. Elizabeth’s management ensures MEP calculations, Energy Modeling, and Building Commissioning meet or, in many cases, exceed the credit requirements. Managing integrated teams for the last thirty years, she knows that smarter solutions and new ways to reduce risk for her clients require continued education in an ever-changing field. Green Living, LLC’s clients include Greystar, Hanover, Hines, Dinerstein, JP Morgan, CDK, Grayco, UDR, and the CORE. Elizabeth is grateful to have entered this industry while it was still in its infancy.

Engineer, LEED AP BD+C, LEED OM, IREE, Austin Energy, IMI Energy Consultant

Ankur Khandelwal has a Masters in Thermal Engineering and Bachelor’s degree in Mechanical engineering. He has 19+ years of experience in Energy simulation, with various programs, LEED MEP calculations, Building Commissioning, and all-around LEED and other sustainability certifications and initiatives. Ankur worked with AECOM in HVAC design before coming to Green Living, LLC. Ankur has simulated 150+ LEED projects with over 22M square feet of LEED and AEGB-registered/certified projects. He has hands-on experience designing building energy systems, focusing on energy conservation thermal and visual comfort for occupants. Ankur manages Green Living, LLC Operations from design through construction, which performs MEP credits with first-pass acceptance from the review teams and all aspects of energy analysis. He is a certified Integrated Modeling Incentive Energy Consultant for AEGB, including Energy Star, has prepared ALL sustainability for all of our Client’s Green Incentives, and is currently enrolled at the University of Texas postgraduate program for A.I. machine learning to incorporate this knowledge to build Energy Modeling “plugin” for Cities to streamline the review process.

Ringkhang Muchahary – Energy Modeler

Mechanical Engineer, LEED AP

Ringkhang has a Master’s degree in Thermal Engineering; he has a decade as of 2023 in Energy Simulation and LEED MEP calculations. He has worked on seventy-eight Energy modeling simulations, LEED MEP credit documentation, and analysis on building energy efficiency measures, including efficient building envelope, efficient HVAC, indoor environmental quality, thermal comfort, onsite power generation, daylighting, use of renewable energy, and efficient water uses. He has an exceptional understanding and passion for energy efficiency, green building, and sustainable concepts and Standards such as ASHRAE-90.1, 62.1, 55, and IECC.

Erika Bonfanti 

Civil Engineer BECx

Has over eleven years of experience in building enclosure design and construction, including condition assessments, leakage investigations, and evaluation and analysis of distress, air leakage, masonry displacement, stucco cracking, and glass breakage. These evaluations have led to subsequent repair and retrofit design of cladding and structural components. Erika specializes in peer review and consulting on new designs, from the schematic phase through completion of construction. She has substantial wealth of building science knowledge that lends itself to her performance of hygrothermal modeling of exterior enclosure systems.

Ankit Rawat

LEED Green Associate and Construction Credit Guru

Ankit has supported all areas of LEED and AEGB Certification Design and Construction requirements and Boston and Denver Green Initiatives. He started with Green Living, LLC in 2019 with five years of LEED construction credit and pre-requisite application experience. Ankit works directly under Ankur Khandelwal and has a B.A.
