Solutions are Available to Save the Planet: How do we get the Public to Demand them?

Some of the most effective climate tech is proven and ready to roll

George Monbiot, columnist for The Guardian, released an article with the eye-catching title “Embrace what may be the most important green technology ever. It could save us all”. The article goes into some interesting detail regarding precision fermentation as a way to grow staple foods. He goes on to point out that, by switching from animal or even soy protein as our worldwide source, we could increase efficiency by a factor of 17,000 (Soy) of 138,000 (Beef).

And, he goes on, in the process this would reduce greenhouse gas emissions and water use by significant amounts. The detail is well presented and, if true, does add up to a world changing, planet saving formula, or at least a major step toward rescue.

The problem? In a nutshell this idea, even if rock solid in the data, would require the entire world to not only change the production methods for food (protein) but we would have to banish centuries of eating customs and traditions.

Ultimately if we are to be saved by this solution, it would only happen when no other food is available. Not a pleasant thought.

Reading between the lines the piece underscores a real and important issue, that finding a planet saving solution for global warming is one thing, finding a way to achieve mass adoption is another.

The Tesla Example

EVs are the most obvious example of a technology, around since before the fossil fuel industry became dominant, that has finally reached a tipping point of eventual total adoption vs. internal combustion engine cars.

The transition, though perhaps inevitable, happend sooner, most would agree, because of Tesla and Elon Musk. And the difference was in the transformation of the concept and image from one of giving up pleasure for the good of the planet to “Have fun going 0 to 60 in 3.1 seconds while you save the planet”.

This formula, don’t sell the problem, sell the beauty, power and pleasure of the solution, is probably going to be the most important factor in deciding if the planet, and humanity, will survive.

Why make such a drastic claim? Because there are more solutions that are ready to be scaled up in a massive push worldwide, without any unproven or yet to be invented technology involved, if only the demand can be boosted with desire and excitement, not fear.

While precision fermentation might be too difficult to market at scale, there are other sectors ripe for positive disruption and change, that could save us all.

Unfortunately, not everything is as endorphin inducing as pounding the pedal to the metal in a Model S Plaid edition. Some things, like superior design, are only exciting when the results are felt over time.

The important thing is to make sure that attention is paid, not just to the climate benefits, but to the superior aesthetics and owner experience made possible by the new thing.

New built communities using hyper-efficient design and sustainable energy

Design technology that can reduce the energy required to heat and cool homes and buildings by up to 90% is available right now and proven. This method, combined with sustainable energy systems, including grid interactive generation and storage, could ultimately remove nearly 40% of worldwide emissions that can be traced back to to construction and buildings.

Not only would the new infrastructure in towns and cities eliminate greenhouse gas emissions but a host of other benefits for health, such as indoor air quality, would be automatically improved.

Further, climate adaptation, the ability to continue to live in maximum comfort even when the outdoor temperatures are at high or low extremes, would be built-in.

As if this is not enough, at scale, with some propagated construction and manufacturing intelligence added, the cost for all of this? Less than zero, in other words, the same or less than the current costs for obscenely inefficient “business as usual” homes and buildings.

So why is this not already a new standard, even mandatory?

For much the same reason it took more than a century for Tesla to come along and change the car industry. The challenge is to change the perception of the product. To build a focus on the beauty, power and excitement of a real life solution that does not trade fun and abundance for austerity and “do it because it’s right”.

There has to be so much momentum toward such an obviously superior concept that the public, the people that will live work and play in the structures, will demand nothing less.

This quote lays out one of the challenges, support and funding for efficiency, in a nutshell

“In our house we save 97% of the pumping energy by properly laying out some pipes. Well, if everyone in the world did that to their pipes and ducts, you would save about a fifth of the world’s electricity, or half the coal-fired electricity. And you get your money back instantly in new-build or in under a year typically in retrofits in buildings and industry. And yet, this sort of energy efficiency is not taught, and it’s certainly not in any government study or climate model. Why not? Because it’s not a technology. It’s a bloody design,”

Amory Lovins, cofounder (1982) and chairman emeritus of RMI, integrative designer of super-efficient buildings, factories, and vehicles

The challenges are layered but can be overcome

Tesla was subsidized, to the tune of $2.48 billion for ZEV credits alone, and more than $.3.2 billion in total from the State of California, but bear in mind that this is just one state, the total is far higher if all of the US is included.

The accomplishment, changing the perception of the EV and, ultimately, causing a worldwide shift toward sustainable transport to be accelerated, is no less remarkable, subsidies or not.

The point should be, that another mature design and technology, the hyper-efficient design system for homes and buildings as described above, needs both the genius marketing push and the financial support, both public and private that Tesla had.

It’s important to note, that Tesla did not invent the electric car. As a matter of fact, they were more than 100 years late to the party. Without Elon Musk as an early investor (with his own funds) the entire story might never have happened.

All of this just underscores the magnitude of the challenge. The perception of solutions like hyper-efficient building design as optional or unnecessary must be destroyed in favor of a focus on the excitement of a better built world and a more affordable magnificence and beauty, within reach now and will exist for all future generations.

If you are reading this and you get it – reach out, shout out, respond in every way you are able to help the world begin the march toward a positive change that is possible, and fun.

Passive House is at the Heart of the Next Wave of Sustainable Infrastructure

Transportation has been the focus, due to Tesla’s rise, but houses and commercial buildings are next

When Tesla was still just an oddball upstart, there was plenty of skepticism that they would survive, let alone change the industry and define sustainable transportation and the future of EVs. This was before Tesla’s stock price soared, even as the climate crisis has become more serious.

Although the stock market is as irrational as ever, on another level the massive rise in market cap for the once underdog sustainable energy focused company can also be seen as a vote from the general public – a vote for the transition away from fossil fuels and toward a sustainable energy future..

Fast forward to 2022 and there is an entirely different situation in the automotive and transportation industries. The entire industry is shifting, rapidly, to 100% electric vehicle production and competing for the climate conscious upwardly mobile customer base that was first identified by Tesla’s “S3XY” marketing methods and designs.

Another underdog – Passive House is ready for the next wave of climate conscious changes

Although sustainable transportation infrastructure still has a long way to go and many issues to overcome, the speed of the transition over the last decade is, nevertheless, impressive.

The next phase of the transition toward sustainable energy infrastructure as a whole, however, is clearly going to be energy generation, solar, wind, geothermal and beyond. This will include design and construction of dwellings and commercial real estate with an eye toward efficient ways to decrease the carbon footprint and create structures that have a low carbon cost (embodied carbon and green cement, use of natural materials, etc.).

Passive house, a concept first pioneered in Germany, is at the center of the coming design revolution in architecture and sustainable construction. Andreas Benzing, of A.M.Benzing Architects PLLC has been at the forefront of the New York, NY movement (as executive director of NY Passive House) as it has grown for nearly two decades and is now ready to break out.

Emphasizing the active role that passive house can play in reaching ‘peak performance’ for dwellings and commercial structures, Benzing elucidates his credo and underscores the similarities to Tesla’s higher-end approach to EV’s, now poised to spearhead a similar revolution in architecture; “We strive to better user experience and comfort, engineer to easily achieve peak performance, and maximize the durability of quality materials.”

The books below are a few that show the history and concepts behind passive house from various perspectives. Houses and buildings that have a reduced carbon footprint, while at the same time generate energy from sustainable sources are becoming feasible and all have as a foundation the passive house standard for highly efficient design.

The New Net Zero

The new threshold for green building is not just low energy, it’s net-zero energy. In The New Net Zero, sustainable architect Bill Maclay charts the path for designers and builders interested in exploring green design’s new frontier net-zero-energy structures that produce as much energy as they consume and are carbon neutral.

In a nation where traditional buildings use roughly 40 percent of the total fossil energy, the interest in net-zero building is growing enormously-among both designers interested in addressing climate change and consumers interested in energy efficiency and long-term savings. Maclay, an award-winning net-zero designer whose buildings have achieved high-performance goals at affordable costs, makes the case for a net-zero future; explains net-zero building metrics, integrated design practices, and renewable energy options; and shares his lessons learned on net-zero teambuilding.

Designers and builders will find a wealth of state-of-the-art information on such considerations as air, water, and vapor barriers; embodied energy; residential and commercial net-zero standards; monitoring and commissioning; insulation options; costs; and more.

The comprehensive overview is accompanied by several case studies, which include institutional buildings, commercial projects, and residences. Both new-building and renovation projects are covered in detail. 

The New Net Zero is geared toward professionals exploring net-zero design, but also suitable for nonprofessionals seeking ideas and strategies on net-zero options that are beautiful and renewably powered.

The Solar House

Passive solar heating and passive cooling–approaches known as natural conditioning–provide comfort throughout the year by reducing, or eliminating, the need for fossil fuel. Yet while heat from sunlight and ventilation from breezes is free for the taking, few modern architects or builders really understand the principles involved.

Now Dan Chiras, author of the popular book The Natural House, brings those principles up to date for a new generation of solar enthusiasts.

The techniques required to heat and cool a building passively have been used for thousands of years. Early societies such as the Native American Anasazis and the ancient Greeks perfected designs that effectively exploited these natural processes. The Greeks considered anyone who didn’t use passive solar to heat a home to be a barbarian 

In the United States, passive solar architecture experienced a major resurgence of interest in the 1970s in response to crippling oil embargoes. With grand enthusiasm but with scant knowledge (and sometimes little common sense), architects and builders created a wide variety of solar homes. Some worked pretty well, but looked more like laboratories than houses. Others performed poorly, overheating in the summer because of excessive or misplaced windows and skylights, and growing chilly in the colder months because of insufficient thermal mass and insulation and poor siting.

In The Solar House, Dan Chiras sets the record straight on the vast potential for passive heating and cooling. Acknowledging the good intentions of misguided solar designers in the past, he highlights certain egregious–and entirely avoidable–errors. More importantly, Chiras explains in methodical detail how today’s home builders can succeed with solar designs.

Now that energy efficiency measures including higher levels of insulation and multi-layered glazing have become standard, it is easier than ever before to create a comfortable and affordable passive solar house that will provide year-round comfort in any climate.

Moreover, since modern building materials and airtight construction methods sometimes result in air-quality and even toxicity problems, Chiras explains state-of-the-art ventilation and filtering techniques that complement the ancient solar strategies of thermal mass and daylighting. Chiras also explains the new diagnostic aids available in printed worksheet or software formats, allowing readers to generate their own design schemes.
