Founding and Early Initiatives (2009-2014) 

 BE-Ex was founded in 2009 and has been instrumental in advancing New York’s climate mission. Through its public energy efficiency resource center in downtown Manhattan, BE-Ex has provided critical tools, education, and exhibits, addressing the urgent mission to reduce greenhouse gas emissions from buildings. 

 The roots of BE-Ex trace back to the Bloomberg Administration and the publication of PlaNYC, in 2007, which laid the foundation for sustainable urban development. Recognizing a knowledge gap, the administration helped launch Green Light New York (GLNY) –now known as Building Energy Exchange– to foster discussions on cutting-edge lighting technologies. Significant milestones included the release of GLNY’s first research report Let There Be Daylight, advocating for advanced daylighting systems in 2012, the opening of GLNY’s first-ever exhibit in 2014, “Bright Ideas for a Resilient World”, showcasing low-carbon lighting solutions and their ability to strengthen vulnerable communities, and the creation of the annual Daylight Hour campaign, which raises awareness about energy reduction and motivates people all around the world to turn off non-essential lighting in their offices and homes. 

“Since its founding, Building Energy Exchange has been a key ally to New York City as it advances world-leading climate policy,” said Rohit T. Aggarwala, New York City Chief Climate Officer and commissioner, Department of Environmental Protection. “Ensuring that building owners and building professionals understand the state of the art in energy efficiency is more important now than ever as we work to mobilize our city’s large buildings to fight climate change and I look forward to continuing this fruitful partnership.” 

“I would like to congratulate the Building Energy Exchange on a remarkable decade of transformative initiatives and unwavering dedication to advancing energy efficiency,” said Council Member James F. Gennaro, Chair of the New York City Council’s Committee on Environmental Protection, Resiliency and Waterfronts.Today, we celebrate the many achievements of BE-Ex. I extend our heartfelt congratulations to all the honorees who have played a pivotal role in shaping a more sustainable future – most especially my good friend Rit Aggarwala, NYC Chief Climate Officer and Commissioner of NYC Department of Environmental Protection.” 

“For 15 years, Building Energy Exchange has helped building stakeholders reduce GHG emissions and create healthier air for all New Yorkers,” said Elijah Hutchinson, executive director, Mayor’s Office of Climate & Environmental Justice. “As New York City and State work to meet our ambitious climate goals and support buildings in decarbonization, BE-Ex educates, shares resources, and gets sustainability done.” 

 “I’m excited to celebrate a tremendous decade of great work by the Building Energy Exchange! They are helping New York City tackle the climate crisis by leading the way on viable decarbonization strategies and connecting New Yorkers to the resources they need to build a healthier, greener City.” – Council Member Lincoln Restler 

 Expansion and Growing International Influence (2015-2019) 

 The launch of the new BE-Ex center in 2015 marked a significant expansion, providing a dynamic hub for industry education and collaboration, and a new name –Building Energy Exchange– to better recognize its holistic approach to comprehensive building improvements. 

The Women in Sustainability and Energy (WISE) series, initiated in the same year, emphasized BE-Ex’s commitment to equity and inclusivity in the energy efficiency space. 

 BE-Ex’s ongoing growth was highlighted in 2016, with the celebration of its 400th program. Recognition as a founding UNECE International Centre of Excellence on High Performance Buildings, in 2018, emphasized BE-Ex’s noteworthy leadership in the industry beyond New York. 

 After a $1.5 million publicly and privately financed renovation, the Exchange re-launched in 2018, with greatly enhanced capabilities and increased activities. 

 2019 saw the passing of the Climate Mobilization Act (CMA) by New York City and the Climate Leadership and Community Protection Act by New York State (Climate Act). BE-Ex played a crucial role in driving awareness, education, and compliance with these landmark legislations by developing a new exhibit, Anatomy of an Energy Efficient Building; creating the LL97 Carbon Calculator, an interactive tool that generates estimates of a building’s carbon thresholds and potential LL97 penalties; and launching the Climate Mobilization Act Educational Series 

 Doreen M. Harris, President and CEO, NYSERDA said, “Congratulations to BE-Ex for 10 impactful years! It is an honor to be a part of their history and to be recognized for NYSERDA’s work in support of the State’s nation-leading climate goals. NYSERDA looks forward to growing our partnership with BE-Ex and other industry change drivers to bring forward clean, resilient solutions for buildings that will ensure New York is a cleaner, healthier place to live and work for all.” 

 “For more than a decade the Building Energy Exchange has brought together the best and the brightest to help New York’s building owners reduce greenhouse gas emissions,” said Greg Elcock, vice president, Customer Clean Energy Programs. “Con Edison is proud to be a part of this important organization and applauds the work it has done. We look forward to working together to meet the challenges that the next ten years hold as we usher in the clean energy future.” 

 “The Building Energy Exchange and its dedicated staff have done an amazing job over the last 10 years growing and developing the organization and positively impacting the environment and local communities. This has been achieved through their education forums, insightful studies and podcasts, and a plethora of other resources related to the energy industry. National Grid is proud to be a long-standing sponsor and supporter of BE-Ex. We congratulate them on their 10-year anniversary and commitment to fostering a sustainable and resilient cleaner energy future.”- Louis Rizzo, National Grid Manager of Customer Energy Solutions NY and BE-Ex Board Member” 

 The New Business as Usual (2020-2022)  

 In response to the COVID-19 pandemic, BE-Ex demonstrated resilience and innovation by quickly launching virtual engagement opportunities, including webinars, an online version of the Anatomy of an Energy Efficient Building exhibit, and the Radio BE-Ex podcast series. 

 In 2021, BE-Ex unveiled BE-Ex Ed— a robust, interactive e-learning platform that offers accredited on-demand courses globally. Initiatives like the Low Carbon Multifamily Retrofit Playbooks, the Beyond Zero Series, and the High Rise / Low Carbon series highlighted BE-Ex’s commitment to empowering all stakeholders with actionable insights for building decarbonization.

 As other regions across the country began to grapple with the challenges of building decarbonization, BE-Ex created the Building Performance Partnership, a collaboration with the Institute for Market Transformation, that has help to create and support independent building resource hubs in Kansas City, St. Louis, Washington D.C, Chicago, and Denver, with more cities in the pipeline. 

 The organization’s commitment to knowledge dissemination extends beyond physical programs, with its website,, evolving into a comprehensive solutions repository accessible to the public. 

 “BE-Ex, under Richard Yancey Jr’s leadership, was a pioneer in the movement to green our city’s buildings and continues to identify and promote new solutions to help meet New York’s ambitious decarbonization goals,” stated Kathryn Wylde, President & CEO, Partnership for New York City   

 “Cross-sector collaboration plays a critical role in the path to decarbonizing New York’s buildings and addressing climate change,” said REBNY Senior Vice President of Policy Zach Steinberg. “REBNY applauds Building Energy Exchange for being such a committed partner in this effort and we congratulate all of today’s honorees for their tireless work to create a more sustainable future.” 

 “As a longtime supporter and collaborator, AIA New York applauds the Building Energy Exchange on reaching this tremendous milestone,” said Jesse Lazar, Assoc. AIA, Executive Director, American Institute of Architects New York. “We commend Richard Yancey and BE-Ex’s demonstrated excellence in promoting sustainable design and climate-conscious policy to effectuate energy efficient solutions in the built environment.”
