About this episode

The episode discusses how building codes contribute to carbon pollution and explores solutions for decarbonization in the built environment.

An interview with Kelly Alvarez Doran Why do our building codes encourage carbon pollution? How have we landed in a "progress paradox," where older buildings often outperform new ones in both operational and embodied energy? In this episode, we sit down with Kelly Alvarez Doran, co-founder of Ha/f Climate Design, to unpack the hidden impacts of the built environment—a sector responsible for nearly 40% of global emissions. The good news is that architects and planners can use their agency to stop these "right now" pollutants. Meaningful decarbonization doesn’t have to cost a premium: Kelly shares how simple material swaps recently slashed a UK project's carbon by 26% (800 tonnes) with zero impact on the budget or schedule. Kelly Alvarez Doran Kelly is a father, architect and educator. His holistic approach to the design of the built environment has been shaped by his experiences working across the world - first in the resource development sector, and later as MASS Design Group’s East African Director where he led the design and implementation of several of MASS’s projects, notably the Rwanda Institute for Conservation Agriculture–winner of several international awards for…
