There are many reasons we might be interested in ultra-low water use.

To begin a list, we might live in an area which has low rainfall and limited water abundance. We may want to reduce expenses from high water use, wherever we live. We might seek to stop unsustainable draws on local groundwater, and thus perhaps ensure adequate spring and surface water for natural wildlife and the carbon-sequestering ecosystems around us. Or either practically or philosophically, we may wish to build off-grid in as many ways as possible, be free of centralized utilities and their bills, and live with a higher degree of natural autonomy, freedom, and resilience than is typical today.

Whatever our motivations for examining and pursuing this goal, let me say upfront that genuinely radical reductions in water use are normally possible in much of the industrially developed world, without significant reductions in our material quality of life. As we will discuss, thanks to modern technology, and in most areas – and almost always in ones with above 30 cm (12 inches) of annual rainfall – it is possible to live a fully modern life with on-site captured rain and other precipitation as our sole source of water.

Importantly, while our discussion will focus on residential or domestic water use, all of its its lessons are directly applicable to commercial and institutional buildings. On the other hand, water use in industrial manufacturing is clearly a separate and more ranging topic, with different issues and differing opportunities across various industrial sectors.

However, while we will only briefly touch on this area here, the case of both industrial and domestic food production is worth highlighting as part of our core discussion. Simply put, with careful water consumption, the use of modern permaculture techniques, and movement to more natural and naturally water-conserving perennial food systems (a topic I have summarized here), the above rule of deriving all needed water from on-site precipitation also broadly applies to agriculture as well.

Lastly for this introduction, our discussion notably will assume the presence of abundant low-cost electricity, a proposal that seems reasonable, across the developed world at least, in our era of increasingly low-cost solar collectors and batteries (a trend I have explored here).

Building Design For Printability

Architects, builders, planners, and developers are doubtless aware that 3D printed buildings and larger communities are on the horizon, with early prototypes now in the popular and professional press. In this approach, large three-axis printers, or alternatives such as ones pivoting from a central point, are used to place materials in a specific order via design and printing software.

While this potential is well-recognized, at least three important aspects of this likely change in construction methods may be overlooked. First is that it will both require and strongly incentivize new Design for Printibality (DFP) standards and practices. On one hand, this will be necessary to enable reliable use of the technology, and also encouraged by the fact that machine-printed buildings with high DFP quotients – from backyard sheds to urban skyscrapers – may become substantially less expensive to construct and maintain than traditionally-built ones.

To Sense Potential Changes, Consider Which Form Is Easier to 3D Print

Second, as my intentionally provocative photo suggests, perhaps few of us have considered how radically DFP may alter building design and engineering, and the typical building shapes and fine-scale design features that we typically employ and take as given today. But to quickly understand this prospect, consider that much of human architecture, historically and in our time, has a low DFP quotient and is likely to be strongly disfavored or disincentivized by 3D technology.

Third, perhaps just as few of us are aware that DFP standards exist already, owing to the rise of desktop and industrial 3D printing, that these standards appear broadly applicable to building design at all scales, and also that they likely offer a significant window onto future building design and construction.

The Most Efficient Building Form

Do you wonder if common building forms or approaches are the most efficient possible?

Since much of architecture and design today, as in the past, is concerned with aesthetics, norms, status, expression, and therefore communication, you may suspect the answer is no, and even strongly no.

But before you answer, let me point out that when we think of form or design efficiency, we can mean more than the direct costs or immediate resources and energy involved in constructing and using buildings, along with the larger settings they create in combination, as important as this is to determining efficiency.

In a complementary and informing way, we also can consider the indirect costs of buildings and developed areas. This crucial but less obvious category of costs or efficiency factors is often substantially overlooked, taken as separate from or beyond the scope of building and development, or expediently treated as “free” to some degree – thereby becoming externalities, or public or unborn costs, in the terminology of economists.

Importantly, indirect building and development costs can be as significant as direct ones. They include the often unexamined costs of pollution, dislocation, future inflexibility, sprawl, resource degradation, eventual obsolescence, and the potential for blight. As a practical matter, such indirect and commonly overlooked costs are essential to understanding the true cost, and thus the true efficiency, of any design, building, or developed area.

Fortunately, we can simplify this complex topic for a general discussion by recognizing that two basic design principles or features often substantially predict both types of costs, and thus the general efficiency of building and development. The first of these principles is that development, buildings, and spaces that are more compact or reduced in scope will tend to be less resource-intensive, less costly overall, and therefore more efficient, as long as they meet essential needs or are effective solutions overall.

The second principle is that buildings, infrastructure, and material inputs using renewable resources – and failing this, readily recyclable or reusable ones – will tend to be less costly and more efficient overall as well, by often producing fewer externalities or indirect costs for others to contend with in time. There are of course exceptions to these two rules. But overall, it is a much more difficult general case to advocate for expansive and non-renewable building and development on efficiency grounds, even as this is still our most common approach to building today.

Automobiles – So Pedestrian

Despite my title, I am not going to rail against the automobile, though I will summarize its obvious flaws, whether piston-powered or electric, and especially in urban areas.

Instead, I mostly want to talk about what we – you and I – can do to quickly offset or improve upon these limitations, while enjoying and even increasing the benefits, opportunity, and natural wonder of motorized commerce and travel for all.

A Typical Day In A Typical City, Nearly Everywhere These Days

As you well know, automobiles suffer from a number of natural drawbacks. This is true in all times, but is a fact increasingly understood and plain in the twenty-first century. These disadvantages of automobiles include their being: 1) expensive to own and operate, 2) resource-intensive and polluting, 3) generally unsustainable as a technology at scale, 4) relatively dangerous to occupants and bystanders alike, 5) physically and ecologically intrusive in the environment, and 6) an enabler of urban sprawl and thereby a promoter of further environmental intrusion and harm.

In addition, automobiles are also naturally and ironically road-congesting when they become the norm – and far more so than other modes of transportation. Automobiles are therefore regularly infuriating, time-wasting, stressful or even soul-destroying (at least to ambitious billionaires), and thus pedestrian. At the same time, however, automobiles and other large motor vehicles have important benefits or advantages. Notably, this includes their ability to carry us and other heavy things great distances and in ways that otherwise might be impractical, difficult, or more costly.

So what to do about all this? While some among us say the problem with automobiles is inadequate roads (or tunnels), the unstoppable ineptitude of their human drivers, or inadequate technological advancement in other regards, all this merely overlooks, extends, or buries the natural shortcomings inherent in widespread and frequent motorized travel.

As an alternative to this, I would like to suggest five steps we all can realistically take to immediately reduce the prevalence and natural harm of automobiles, while simultaneously decongesting our roadways and making high-value automotive transportation more efficient, and even more enjoyable:

#1: Move – if you cannot live, work, and play without an automobile where you reside, you and your family of course have the opportunity to move to a place where you can, and this process can be aided by the reduced costs of not depending on and paying for one or more automobiles to fulfill normal activities of daily life

#2: De-Car – while or after you move, you can sell, donate, or recycle your automobile or automobiles, again reducing costs, but also encouraging car-free, and perhaps more carefree, living on your part

#3: Ride-Share – once you are car-free, you can make full use of your transportation options, including highly social buses and trains, more exclusive ride-sharing services, and still more exclusive automobile rental – in all cases, but proportionately so, reducing your transportation costs and ecological impact on the planet

#4: Walk & Cycle – for shorter trips, and ones without significant things to carry, walking or cycling is of course a waiting, renaturalizing, and health-increasing option, especially if the route has safe walkways or bike paths, which it will if we are careful in step one, or are willing to lobby city hall

#5: Move Again – if your first car-free location proves less than ideal and thus a learning experience, you always can move again, with the added benefit not only of improving your quality of life, but also signalling to planners and developers growing demand for high-quality, car-free housing and living arrangements overall

As I said before, my goal here is not to rage against the machine or advocate elimination of all automobiles. Rather, it is to reduce their ill-considered and needless use, their inherent ecological and financial costs, and their contribution to reduced human health, happiness, and social connection.

Indeed, by following the above steps, not only would we and our cities and towns become healthier and more sustainable, our road systems and roadsides would be significantly emptied and de-cluttered as well – increasing the efficiency of commercial traffic and also restoring the wonder and beauty of driving, when we periodically take a trip and rove the open road away from home.

The Future of Electricity

Essential to modern design, building, development, and economic investment, on many fronts, is an understanding of electricity. Not so much how electricity works, but how it will be created and provided in the future – whether to homes, businesses, whole communities, or industry.

In much of the world today, electricity is of course primarily generated in power plants and transmitted via electrical grids by utilities of various types and sizes (see Ta’u for an example of a new and growing exception). Power plants in our time generally use natural gas, diesel, coal, nuclear fission, or dammed water to turn large generators. However, as you likely know, a small but increasing part of this mix is electricity from solar power plants, rooftop solar panels, and wind turbines.

What may be less clear is that much of this is likely to change, and perhaps soon and quite rapidly or radically. In a decade or two, electricity may be increasingly generated by building-installed solar panels or sheathing, stored in batteries where it is generated, and no longer transmitted by power grids at all. Power poles in residential and commercial areas may be coming down, traditional electrical utilities may be facing bankruptcy, and large power plants and long distance transmission systems may have begun to become obsolete.

A Gridless, Solar-Powered Future May Be Driven By Simple Economics

If this idea or prospect seems uncertain or doubtful to you, let me make the case why it may be likely and even inevitable, and also give you an idea of what more decentralized – or more naturally distributed, autonomous, and democratic – off-grid power systems might look like in the future. Importantly, let me add that these new building-level power systems may, in turn, usher in or become part of a larger movement to modularize and automate building and development more generally, perhaps significantly reducing building construction (or installation) costs, as I will explain.

Self-driving or autonomous cars and trucks are coming, and soon. Not only are the number of firms developing the technology increasing, regulatory barriers and public skepticism are receding, and the initial rollout of the vehicles is proceeding successfully.

As I write this, Google brethren and early market-leader Waymo has driverless, level-4 autonomous vans roaming the streets of Phoenix, Arizona, with plans to expand and achieve fully autonomous, level-5 functioning in the near term.

Self-Driving Technology May Change The Way We Live Overall

But what about self-driving or autonomous motorhomes, or mobile homes, here meaning more than mere recreational vehicles? As autonomous vehicle technology proliferates, self-driving mobile homes cannot be far behind, and perhaps with far-reaching consequences. After all, if we could live and move in our homes, and not have to drive or steer them, many of us might choose to no longer have fixed homes, and to live far more mobile or location-flexible lives than we do today.

Consider some of the potential key features of mobile living, if we could live and work, and not have to drive, as we move:

Green Building: More Than LEED

In many countries today, there is a rapid movement toward green building.

Often, however, this goal is cast somewhat narrowly – as creating buildings that require little or no external energy for their daily use, or fabricating structures with a fairly high degree of autonomy.

While this goal is laudable and has led to a number of important innovations, there are at least two broader, more rigorous, and ultimately more socially beneficial ways to conceive of green building design.

A second, broader conception of green building also considers the amount and nature of resources that go into the initial construction of buildings. In this expanded definition, architects, builders, developers, and regulators seek to: 1) minimize resource use during building construction, 2) reduce reliance on non-sustainable or non-recyclable resources, and 3) build in ways that are either minimally impact or positively enhance land, water, and air quality around buildings and their communities. As you may know, this sense of green building design is increasingly more common – and can be explored at green building.

A third and still more expansive definition of green building further extends the concept to include consideration of the long-term ecological and social impacts of building and development overall. In particular, this view enlarges our analysis to assess the relative effectiveness of building and development patterns both at meeting human needs and promoting human health, including the essential foundation of all natural health that is ecological sustainability.

What Is The Correct Scope For Green Building & Development?

Importantly, and often somewhat unintuitively or inexpeditiously, the natural – or renaturalized – goals of meeting human needs and promoting human health generally lead to a basic rethinking of traditional building design and construction practices, along with community and societal development norms more broadly. This is a complex topic, but let me point out that the aim of serving human needs and promoting overall community and societal health invariably must consider how building and development impact people generally, and how these efforts can serve the greatest number of people.
