[Episode #218] – Accelerating Decarbonization in the US

Feb 21 2024

How can we accelerate the decarbonization of the entire US economy?

In this episode, we discuss the energy-related decarbonization strategies outlined in a new report from the National Academies, titled “Accelerating Decarbonization in the United States: Technology, Policy, and Societal Dimensions,” with Dr. Sue Tierney, a Senior Advisor at Analysis Group and a renowned expert in energy and environmental economics, regulation, and policy. Dr. Tierney played a key role in the Committee on Accelerating Decarbonization in the United States, which developed and coordinated this landmark study. We explore how decarbonizing the US requires much more than simply substituting renewables for fossil fuels in power generation and EVs for oil-burning cars. A broad array of solutions must be deployed, but they face numerous barriers and risks to implementation.

Trillions of dollars have been allocated for these energy and technology solutions through three significant laws passed in 2022: the Infrastructure Investment and Jobs Act (IIJA), the Inflation Reduction Act (IRA), and the Creating Helpful Incentives to Produce Semiconductors (CHIPS) Act. However, effectively mobilizing these funds requires willing collaboration from a diverse group of local, municipal, and state actors, including elected officials, regulators, agency staffers, as well as community and business leaders.

Listen in to learn why delivering a successful energy transition, along with a host of other benefits such as justice, equity, health, jobs, and sustainability writ large, necessitates understanding the barriers to implementation and identifying the types of policies and programs needed to keep the US on track to achieving net zero.

[Episode #217] – Passivhaus in Scotland

Feb 7 2024

Mini Episode

Discussions about energy transition often overlook the crucial role of reducing the energy consumed to maintain comfortable temperatures in the spaces where we live and work. Remarkably, generating heat, the largest end-use of energy, accounts for 40% of global fossil CO2 emissions, with the majority of this heat used in buildings. About half of the energy used in buildings is for their heating and cooling, and because fossil fuels still meet the bulk of heating energy demand, this contributes to about one-fourth of global energy-related carbon emissions annually.

Addressing this challenge by improving building efficiency and reducing thermal losses is arguably the most critical step we can take to facilitate the energy transition. However, strong policies or targeted programs to this end are largely absent worldwide.

A transformative solution is the adoption of the Passivhaus standard for new and existing buildings. Retrofits to meet this standard could drastically reduce energy requirements for buildings, accelerating our progress toward the energy transition.

In this episode, we are joined by Es Tresidder, a Passivhaus consultant who works with an architecture firm to advance the use of the Passivhaus standard and techniques. He walks us through the Passivhaus standard and how to meet it. He also shares the story of the ‘deep retrofit’ performed on his own house in the rainiest and coldest part of Scotland, transforming it into a home that is far healthier and more comfortable, all while significantly reducing its energy consumption.

Guest:

Dr. Es Tresidder is a Passivhaus designer based in Fort William. He works as a Passivhaus and energy specialist for John Gilbert Architects, one of the leading environmental architecture practices in the UK. His work at John Gilbert Architects currently focusses on their larger and more complex projects – Passivhaus schools, leisure centres and retrofits. Es has a PhD in low energy building design optimization, using genetic algorithms to optimize building designs for efficiency and cost. In 2023 he finished a retrofit, to Passivhaus EnerPHit standard, of his own home in Fort William, Scotland. Once certified he believes this will be the first EnerPHit of a modern timber-frame house in the UK, and potentially the world.

[Episode #208] – Vernacular Architecture

Oct 4 2023

Mini Episode

Can ancient architectural and building techniques help us create comfortable spaces without consuming energy in today's world?

Our guest in this episode thinks so.

Dr. Sandra Piesik is an award-winning architect, author, and scientist with extensive experience in what is now called “vernacular architecture.” Among many other things, she specializes in agitating for legislation supporting sustainability and nature-based solutions to the climate challenge.

She has published two books on vernacular architecture, including Habitat—Vernacular Architecture for a Changing Climate, published in May of this year. In it, she curates the work of an international team of more than one hundred experts across a diverse range of disciplines, who examine what the traditions of vernacular architecture and its regional craftspeople around the world can teach us about creating a more sustainable future. With over 1000 illustrations, the book reveals how people and cultures have used indigenous materials and construction techniques in all five of the planet’s climate zones to create comfortable built environments, and it stresses the importance of preserving disappearing craftsmanship and local knowledge before it is lost forever.

In today’s conversation, we discuss what ‘vernacular architecture’ is, what some of the specific techniques are, how those techniques could be used today, and what’s preventing us from using them. We also discuss the role of vernacular architecture within the broader context of sustainable development, and what a holistic approach to the UN’s Sustainable Development Goals might look like.

[Episode #123] – Sustainable Energy Transitions

Jun 10 2020

Mini Episode

Addressing the threat of climate change means executing a successful energy transition. But as the transition proceeds, we are increasingly having to confront the impacts of transition technologies, and consider the trade-offs of choosing those technologies over the conventional technologies that they are displacing - because nothing we can do is without an impact of some kind, and everything we build requires the use of raw materials. So the question of what is truly sustainable is beginning to take a larger importance in the formation of policies designed to advance energy transition.

But energy is still being taught primarily as part of the engineering discipline, leaving students from non-engineering disciplines in need of ways to learn something about energy, in order to help them be more effective in their work. Fortunately, professor Dustin Mulvaney of San Jose State University in California has a new textbook designed to address this need, titled “Sustainable Energy Strategies: Socio-Ecological Dimensions of Decarbonization.” It’s a very ambitious effort to survey many of the complex topics that are critical for people involved in energy transition to understand. In this episode, we talk with Dustin about why he wrote it, and we take a walk through each chapter in the book to understand the complex questions around what “sustainability” really means in the context of energy transition.

[Episode #84] – Designing Climate Solutions

Dec 12 2018

Mini Episode

If you wanted to design a set of policies that would reduce greenhouse gas emissions worldwide, right now, where would you start? How would you figure out which sectors of the economy to target in order to have the maximum impact? Which policies would you choose? How would you go about designing them?

And which sectors of the economy would you target in order to reduce emissions the most? Transportation, maybe? Improving the efficiency of our buildings? Would you believe those two sectors rank at the very bottom of the list?

In this episode, we interview one of the authors of a new book by Energy Innovation titled Designing Climate Solutions, which is like a how-to manual for climate policy, identifying the major sectors of the economy that we should target to eliminate as much greenhouse gas as quickly as possible, and the specific policies that can achieve those reductions. We guarantee you will find some surprises in this one!

[Episode #80] – Building Infrastructure as a Service

Oct 17 2018

Mini Episode

If you owned a building, or a long-term lease on a commercial space, would you rather shop for your own building infrastructure—things like HVAC systems—or would you rather buy it as a subscription service from a trusted utility or power provider? Our guest in this episode offers the latter, and it’s an intriguing model for how we might upgrade the equipment for commercial and industrial buildings. There are reasons why 68% of the HVAC equipment in commercial buildings in the US is nearly three decades old and in need of replacement, and those reasons are about the cost, complexity, and difficulty involved in that kind of procurement. Wouldn’t it be better if you could call up your local utility and ask them to upgrade your equipment, using their network of trusted and reputable equipment experts and installers, and then just paid them a small amount for the use of that equipment every month, rather than having to pay thousands of dollars for it up front and taking all of the performance risk upon yourself? From high-efficiency lighting, to HVAC controls and sensors, to other energy-consuming building equipment, Sparkfund offers a subscription approach to procurement backed by a no-risk guarantee, which could unlock a huge opportunity to improve the efficiency of our commercial and industrial building systems more quickly than we do under the status quo.

[Episode #77] – Perspectives of an Energy Transition Veteran

Sep 5 2018

Mini Episode

Energy transition has been under way for the better part of two decades now, and it’s easy to forget how much the world has changed over the time. We now have a host of energy technologies and consumer tools that didn’t even exist 15 years ago. Utility business models have been turned upside-down and we’re still not sure what they’ll look like in the future. Equally, there has been a transformation in education as it tries to catch up with a rapidly-changing world and an ever-more-urgent call to action on climate change. Viewed up close, the transition now underway can look pretty slow sometimes, but if you back up and review what has transpired over the past 15 years, it has actually been incredibly rapid, at least compared to the historical pace of change.

Few people have been as involved in energy transition over the past 15 years, and have seen it as up close and personal as our guest in this episode. Robyn Beavers has had a remarkable career working in energy transition that included stints at Google, NRG, the Department of Energy, and Vestas, and she did it all starting as a young woman in an industry dominated by men. In this interview she shares some of her insights on how it all has unfolded, and how she has managed to be incredibly successful with navigating the gender disparity. She also explains how her new venture is working to turn the built environment into dynamic energy assets. If you’re a young person interested in breaking into the world of energy, you don’t want to miss this episode!

[Episode #53] – Electrifying Heating

Oct 4 2017

Mini Episode

“Deep decarbonization” is all the rage in energy circles, but what does it really mean for actually retrofitting and remodeling buildings? Is it just about replacing oil and gas-fired boilers and furnaces with electric equivalents? Or does it actually mean something far more complex and interesting? Our guest in this episode is a registered engineering technologist in building construction technologies and an award-winning expert on the integration of the building sciences and health sciences who believes the best solutions come from an integrated design approach that takes all elements of buildings and human experience into account, not just how we heat our buildings. This lengthy, wide-ranging, and often humorous discussion covers everything from building science, to regional and national politics, to human physiology and psychology, to the ways that we teach architecture and building design, and much more…and it will leave you with an entirely new concept of what “deep decarbonization” really means. Plus: we finally delve into the arcane but important concepts of exergy and entropy.
