A Close (But Not Too Close) Look At Personal Space

Boundaries of personal space can depend on geography and wealth. City planners and interior designers should keep it all in mind when drawing up blueprints for the future.

BUENOS AIRES — The problem with Guille is that he's a close talker. It's not like he has nasty breath or smells bad, but he gets in your face, even as you keep inching back. Leandro is the opposite: You try to move closer to talk to him, and he steps away. As you feel the need to approach a bit more, he again retreats, like in some kind of ritual dance.
A while back, I realized the reason for this is that each of us has our own idea of what represents an ideal distance with people, a bubble that feels neither too crowded nor too distant. Guille's bubble is clearly much smaller than mine, and Leandro's much bigger.
In 1966, anthropologist Edward T. Hall was the first to discuss this subjective frontier, or "personal reaction bubble," which influences our behavior. His book The Hidden Dimension describes four types of space: intimate space (about 46 centimeters around us), which is normally reserved for lovers, children, close relatives, friends and pets; personal space (from 46 to 120 centimeters), used in conversations with friends, colleagues or at gatherings of people you know; social space (120 to 240 centimeters), meant for strangers, new acquaintances or members of recently formed groups; and public space (more than 240 centimeters), used for large gatherings, public speaking, seminars or the theater.
Clearly Guille's personal space is less than 46 centimeters, which is why he's always entering mine, and Leandro's is bigger, which is why his body language always suggests that I'm encroaching on his! Hall was very clear on this: Personal space draws out our comfort zone and psychological security, but it's very difficult to measure. It changes according to personal experiences, culture, the time we live in, age groups and social classes. In the West, for example, Hall's studies found that the average person's personal space extends 60 centimeters from each side of the body, 70 centimeters to the front and 40 behind. But in Latin cultures, it's smaller. Anglo-Saxons seem to require the most.
The personal space divide
There are also social differences. Rich people expect to have larger personal space than the poor, who tend to live closer together. In large cities such as Buenos Aires, personal space tends to be smaller than in the countryside.

In some situations, people make exceptions about their personal space because life demands it: taking the subway, getting into the elevator, going to a concert or taking part in protests all require sacrificing personal space a bit. In these cases, people respond differently: they accept the discomfort more graciously, for example, if it's for fun or just for a short while. With public transport, it's different.
Psychologist Robert Sommer says people tolerate crowds on subways, buses and elevators by dehumanizing those next to them. That is, they regard them almost as objects instead of people invading their intimate space. Which explains why people tend not to make eye contact and look so lifeless on the subway.
The point is, distance influences our behavior and should, therefore, be considered when it comes to designing and furbishing buildings. Experiments on human communication have shown, for example, that people prefer to face each other when talking, rather than sitting next to each other. Obviously, you might say, so they can see each other's faces. Yet those studies also show that as personal distance increases, they prefer to sit beside one another, even in the best acoustic conditions. That is, we tend to keep ourselves inside our personal space.
Another finding is that the size of a room determines conversational distance. In smaller rooms, people tend to move closer, rather like my friend Guille.

In Argentina, A Visit To World's Highest Solar Energy Park

With loans and solar panels from China, the massive solar park has been opened a year and is already powering the surrounding areas. Now the Chinese supplier is pushing for an expansion.

960,000 solar panels have been installed at the Cauchari park

CAUCHARI — Driving across the border with Chile into the northwest Argentine department of Susques, you may spot what looks like a black mass in the distance. Arriving at a 4,000-meter altitude in the municipality of Cauchari, what comes into view instead is an assembly of 960,000 solar panels. It is the world's highest photovoltaic (PV) park, which is also the second biggest solar energy facility in Latin America, after Mexico's Aguascalientes plant.

Spread over 800 hectares in an arid landscape, the Cauchari park has been operating for a year, and has so far turned sunshine into 315 megawatts of electricity, enough to power the local provincial capital of Jujuy through the national grid.


It has also generated some $50 million for the province, which Governor Gerardo Morales has allocated to building 239 schools.

Abundant sunshine, low temperatures

The physicist Martín Albornoz says Cauchari, which means "link to the sun," is exposed to the best solar radiation anywhere. The area has 260 days of sunshine, with no smog and relatively low temperatures, which helps keep the panels in optimal conditions.

Its construction began with a loan of more than $331 million from China's Eximbank, which allowed the purchase of panels made in Shanghai. They arrived in Buenos Aires in 2,500 containers and were later trucked a considerable distance to the site in Cauchari . This was a titanic project that required 1,200 builders and 10-ton cranes, but will save some 780,000 tons of CO2 emissions a year.

It is now run by 60 technicians. Its panels, with a 25-year guarantee, follow the sun's path and are cleaned twice a year. The plant is expected to have a service life of 40 years. Its choice of location was based on power lines traced in the 1990s to export power to Chile, now fed by the park.

Chinese want to expand

The plant belongs to the public-sector firm Jemse (Jujuy Energía y Minería), created in 2011 by the province's then governor Eduardo Fellner. Jemse's president, Felipe Albornoz, says that once Chinese credits are repaid in 20 years, Cauchari will earn the province $600 million.

The Argentine Energy ministry must now decide on the park's proposed expansion. The Chinese would pay in $200 million, which will help install 400,000 additional panels and generate enough power for the entire province of Jujuy.

The park's CEO, Guillermo Hoerth, observes that state policies are key to turning Jujuy into a green province. "We must change the production model. The world is rapidly cutting fossil fuel emissions. This is a great opportunity," Hoerth says.

The province's energy chief, Mario Pizarro, says in turn that Susques and three other provincial districts are already self-sufficient with clean energy, and three other districts would soon follow.
