#buildforchange
"The way we have been building... for the past 150 years is an anomaly in human history..."

We know how to build a 100 or 500 year structure using materials w/ less embodied energy, natural ventilation, geothermal cooling, solar heating. We must get back to that wherever possible #buildforchange
For thousands of years, humans have built almost exclusively using materials provided by nature in their immediate surroundings. This approach, based on earth (clay), wood, straw and stone, was a highly intelligent system perfectly adapted to the local climate and available resources.

There's always someone defending the business as usual status quo. Instead #buildforchange #decarbonizenow #notimetowait
"We have to bring people along." – Is this said because I’m demanding too much? Or is it the perfect shield: admitting a transition is necessary while blaming the delay on those (supposedly) "slow others"?

I’ve known the CO2 facts since I was 12. At nearly 50 now, more than enough "bringing along."

Your content is awesome & your engagement provides people who want to #buildforchange easier. We've literally modified designs b/c of ideas you offered. Appreciation from this side of the 🌊

Today's #hempcrete update is that the industrial mixer is on site for batching 12 ft³ at a time. The #hemp #hurd, the woody biomass from the stalk, is stunningly lightweight.

#buildforchange requires us to go back in time, sometimes using new methods, to achieve what those came before us knew: bldg built of earth, timber, lime, clay, straw & hemp that were designed to work w/ the sun to passively heat & cool using fountains, plants & courtyards for shade work w/ ⬇️ impact
The pleasant indoor climate is ensured, on the one hand, by keeping the sin out. But the ceiling elements – made from local earth without concrete – also help to maintain the balance.

After today the project could have totally derailed -- again. The bs for no public gain, nay sayers, self serving misrepresentations. Tomorrow is a new day & we will get closer to finishing the basement in the maximally sustainable way; made possible because we did not quit. #buildforchange

Reminder to those of us that want to #buildforchange: if you feel a sense of urgency, don't ask for permission, don't wait your turn, lead. We need to change the way we build for #sustainability & #resilience. This was a funny reminder to plow ahead
Legalize comedy!!!!!

Incredible brick building material #reuse. Each of the bricks was screened out of 1.2+ million pounds of dirt from the excavation on our site, cleaned up & given a new life on a historic property nearby. The dirt also got reused as new fill on a local site. #zerowaste #decarbonize #buildforchange

Study on reducing #embodiedemissions from new construction is broadly applicable. In order of importance to emissions: reducing new construction, using #timber & #straw over steel & foam, #renovating existing buildings, building to last longer, & reducing emissions from concrete #buildforchange

Good morning & to a wonderful week. Here is true building artistry from a historic farmhouse renovation using our broken bricks & discarded slate found on site. This will welcome visitors to the renovated barn.

Let's stop seeing material as trash when it can still create beauty #buildforchange

Let's share the stories of people who #buildforchange. People are researching, developing & building with materials to address #climatechange. Those efforts deserve to be highlighted. We can see the hope while still aggressively pursuing change from business as usual
One of the most important things we all need to know when it comes to climate action is this: we are not alone.

Everywhere I go - like at Princeton yesterday & Michigan today - I meet people doing incredible work to build a better future. When we share what’s happening with others, we build hope.

We're grinding upstairs concrete slab. The person operating the grinder understands the envt sustainability reasons we're using alternative cement, sand & stone even though they're never used. Across language we can create new building paradigms that are better for people + planet #buildforchange

In the light of a new day, the goals we worked for -- lightweight, 96+% ♻️ material concrete slab w/ 85+% ⬇️ emissions via 0 Portland cement & w/o mined aggregate or dredged sand -- were achieved. The screed looks fantastic & we didn't have to compromise the ethos #fridayfruition #buildforchange

17 new to us #reuse steel divided lite windows from the 1920s. They were transformed by removing the glass, sandblasting & modifying the size to fit our space. They'll get used glass if we can resize &/or source it. Start w/ something solid & it will always be in fashion #decarbonize #buildforchange

An uplifting sentiment. We made Portland cement-free walls with 4,000+ psi (the 28 day strength isn't even back yet & will be higher), reducing emissions from the cement change drastically all while radically increasing ♻️ material beyond what literature indicates is possible #buildforchange

next client or sponsor who wants greener concrete can use our 2 mix designs (published here & on our website) as a starting point. We extended what others before us proved out & now our work will be extendable by others too #buildingdecarbonization #greenerconcrete #buildforchange

deploy this in more places w/ a qualified labor pool & contractors who stood by their work. Right now we don't have either in meaningful numbers

Totally. Celebrating wins of any size at any scale is necessary to making change stick. Every project sponsor who can use the academy will lead to a shift we support. More people trained inherently makes more projects possible #decarbonize #buildforchange
