Perhaps it was the architectural rendering of a piece of cake that caught my eye – well done Steven! (FYI as of this writing this post has 564 reactions, 59 comments and 45 reposts- that's influence!)

Meet Steven Biersteker, architect by day and content creator by night. Here is his LinkedIn page:

We explore a lot of topics in this episode including why Steven entered this field and how he got to where he is today. (My favorite part of every episode.)

Other notions we discuss:

Getting to low operational carbon is simple ... in theory. We are running highly efficient buildings on high carbon fuels. Citizens need to demand better and use energy smarter. Designing highly efficient buildings is critical, but so is low-carbon electricity and smart users.

We learned that he's writing a book (ABCs of Carbon + Architecture) because he sees a big problem: There is a huge gap between the know-it-alls and the know-it-nots.

His book will be simple to read, digestible, and most importantly brief (see the book outline below).

And also see below for 10 important questions about low carbon design for every architect and builder to ask themselves/their client.

It's on all of us to work together, you can make a difference. Be willing to ask questions.

This episode was recorded in October 2023.

Here is a sneak peak of the key topics in his book: CARBON LINGO - The Key terms you need to know GLOBAL WARMING 101 - The basics, nothing more SCOPING OUT CARBON - Who's scope are carbon emissions? MEASURING CARBON - How we measure this stuff WHOLE LIFE CARBON - Embodied & Operational Carbon LIFE-CYCLE STAGES - EN15978 - A1 - C EMBODIED CARBON - What's accounted for? MATERIALS - Emissions & carbon sequestering ENVIRONMENTAL PRODUCT DECLARATIONS - The intro to Epd's OPERATIONAL CARBON - The basics of emissions ENERGY USE - How does energy impact GHG REFRIGERANTS - What's the issue with refrigerants? CARBON COMPARISON - So what is a ton of carbon anyway?

BONUS: 10 simple questions to achieve a low-carbon design.

1. Does this building need to be built?

No - Great, you just saved the planet.

Yes - Move on to question 2.

2. Does this building need to be built this big?

No - Build what you need and nothing more.

Yes - Move to question 3.

3. Is there an existing building we could use instead?

No - Let's try and build the best new building we can.

Yes - Renovated buildings reduce embodied carbon by up to 70%

4. Can we use a biogenic material as our structure?

No - Focus on less material and lower impact materials.

Yes - Stick frame and mass timber are great structural options

5. Can the building be designed to come apart?

No - Concrete is the worst material for disassembly.

Yes - Steel and Mass Timber should be bolted for disassembly

6. Can we fully electrify the heating & cooling systems?

No - Maximize energy efficiency through passive system design

Yes - Heat pumps will reduce your energy use by 3x's

7. Can we reduce our mecha
