Flash forward 50 years: The “millennial generation” is reaching retirement age (which is now 78, thanks to ever-increasing life expectancy). That’s right, they are the mature members of society, no doubt complaining about the slacker youth of the day and living in a technologically advanced world we can only imagine. As we begin coverage of the HGTV Smart Home 2014 construction project, let’s take a look at how our children, grandchildren and great grandchildren will live.
Let’s start with the big picture: What neighborhoods will look like. “Over the past 50 years, the biggest trend has been out of compact urban dwellings into sprawling suburban ones,” says Roger Platt, senior vice president at the US Green Building Council. “Over the next 50, the opposite is likely going to happen.” People will want a walkable lifestyle with an urban cool vibe. That means parks, bodegas and entertainment venues nearby and — thanks to population growth — extremely compact houses with multifunction rooms; for example, a single space might triple as living room, dining room and kitchen.
Rising water levels and massive coastal storms may change our methods of building along the shore, says architect Maureen Guttman of the Alliance to Save Energy. Instead of buttressing homes on ever higher, deeper and beefier pilings in the sand, she envisions houses being built on floating barges that can simply be relocated out of harm’s way when hurricanes or nor’easters approach.
Forget 2x4s and wallboard, the house of the future may be built of a material that’s something like concrete but could be manufactured on site using a giant 3D computer printer, says physicist Max Sherman, who leads the Energy Performance in Buildings Group at the Lawrence Berkley National Laboratory. He predicts that this substance will be able to literally change itself from a super-insulating and draft-blocking barrier one minute into a breathable and free-flowing one the next, all depending on the conditions inside and outside.
Heating and Cooling
Thanks to this efficient building material, houses may need only tiny heating systems. Just a bit of added warmth will maintain comfortable indoor temperatures. Large-scale cooling, on the other hand, will still be needed because on hot days, no amount of insulation will keep the ambient temperature down. But air conditioners and even geothermal heat pumps will be things of the past. Physicist Max Sherman predicts that both cooling and heating will be provided by the walls themselves — possibly that newfangled concrete-like material or the paint on its surface — which will contain electronic devices that simply warm or cool on demand, in much the same way that an LED (light emitting diode) bulb produces illumination today.
The roofs and exterior walls of houses will also double as solar energy collectors, using far more effective technologies than today’s photovoltaic cells. “The solar energy that hits the earth in one hour is enough to power all of humanity's energy needs for a year,” says Mark LaLiberte of Construction Instruction, a building efficiency and technology consultancy. “We just don’t know how best to capture it yet.” In the world’s increasingly urban settings 50 years from now, houses will likely be interconnected in “micro-grids” so that those that get the most sun, and therefore create more power than they need, will help to supply nearby units that can’t generate all of their own power. New technologies — and global food shortages — may also make backyard and rooftop gardening feasible as a significant food source for feeding the family, though busy homeowners will likely hire help to tend their mini-farms.
Bob Martin, director of industrial design at Electrolux Major Appliance, predicts the end of dishwashers. “New surface technologies will mean dishes and cookware hardly need any cleaning at all,” he says. Meanwhile, tiny robots could keep houses clean, not by randomly circling the floors to vacuum and mop, but by identifying the moment soil appears on any surface of the house and dispatching a team of smartphone-sized machines to clean it. Rather than a gas or electric cooktop, kitchen countertops themselves may heat pots on command, using induction technology that boils water in seconds yet won’t cause a burn when touched. Ovens will cook to perfect doneness automatically without probe thermometers or human intervention.
Today’s touch screens, remote controls and dashboard apps will seem like quaint relics of the past. Our experts predict that houses will automatically respond to outside weather conditions, to their residents' eminent arrival home, and to commands provided with just a thought.
