Guest bio John Mandyck joined Urban Green Council in 2018 as its first-ever CEO. He capped a 25-year career as Chief Sustainability Officer for United Technologies Corporation, a Fortune 45 global leader in the building, aerospace and food refrigeration industries. He also serves as a Visiting Scientist at the Harvard University T.H. Chan School of
A recent report from Navigant shows that just from implementing existing technology solutions for electrification of transport, energy efficient heating and cooling of buildings and sector integration – urban areas can bridge half of the gap needed to reach the 1.5°C Paris Agreement target in urban areas
John speaks with Clay Nesler about building energy efficiency, especially how it ties to economic recovery and resilience in the face of the global COVID-19 pandemic. Their discussion includes some of the various efficiency standards throughout the world and different approaches to retrofitting existing buildings.
Buildings — with their thirst for electricity, natural gas, and fuel oil — are a major contributor of atmospheric carbon. However, the building stock in the United States turns over, on average, every century, meaning today’s carbon emission output cannot be resolved without deep changes in existing buildings. The task is transformation. The challenges are

Continuing their conversation from last episode, John and Jeff discuss district energy, this time with a focus on a practical example: Sheridan College in Ontario, Canada. Listen how district energy was applied and what benefits were realized from its utilization.
What is district energy? What is its potential for buildings, building networks/campuses, and cities in North America looking to improve efficiency, reduce greenhouse gas emissions, lower operating costs, and ensure resiliency? How is today’s technology affecting market development? Tune in to this episode for a conversation on district energy (including heating and cooling) with Jeff Flannery, Danfoss’ business development manager in North America.
A safe transition to low-GWP refrigerants in the US is made more complex by the Montreal Protocol, the original international treaty finalized in 1987 to phase down Ozone Depleting Substances, or ODS, which included HFC predecessors CFCs and HCFCs. The Kigali Amendment to the Montreal Protocol amended the international treaty in 2016 to reduce greenhouse
In the previous post, we looked at the global path to a safe transition to low-GWP refrigerants, and the impact that actions by states like California are having on creating a patchwork of regulations and move us toward the use of highly flammable refrigerants. Here, I trace how the move impacts standards and codes, as
The global transition to low-GWP refrigerants is beginning in a disorderly manner in the United States — the world’s most mature HVAC market. In the absence of a federal framework, individual states are beginning to regulate HFCs. A handful of states are following SNAP Rules 20 and 21, the EPA regulations that were vacated by
