Can Second Homes Be Sustainable?

"In Minnesota, we nurture cabin dreams," writes Edina Magazine. "The land of 10,000 lakes has been churning out cherished memories for generations, and, naturally, many of us want to continue the tradition. According to the National Association of Realtors, 22 percent of the nation's vacation homes are cabins or cottages; these little dwellings surrounded by nature continue to be popular, providing equal doses of nostalgia and escape from our busy, grown-up lives full of stuff."

Having a second home, of course, is inherently not sustainable in the environmental sense. Not only does a second home require financial and economic resources to maintain, but the travel required to reach a second home (whether by plane, train, boat, or automobile) results in greenhouse gas emissions, air pollution, noise, land use, and water pollution. At the same time, however, many small communities rely on the financial resources second home buyers bring to help sustain their livelihoods.

As Dr. Ziene Mottiar, Faculty of Tourism and Food, Dublin Institute of Technology, notes, "there are two seemingly paradoxical aspects to sustainable development, namely conservation and development… Thus it is a matter of preserving, for instance, the wealth of species in a natural area, and at the same time, striving for development in a society to attain the goals of greater welfare for the people. This necessitates the management of 'the process of change in such a manner that it occurs in as benign a way as possible rather than by accident."

In addition, one aspect of sustainability is resource utilization. A home sitting empty is simply wasting resources, whereas one used for people is serving a purpose. Rise wrote about how Airbnb can increase the sustainability of your home because it allows homeowners to rent out their homes or extra rooms that are not being used, thereby providing shelter for more people.

A Look at My Family's Second Home

Acquiring a second home can happen in ways other than purchasing a cabin "Up North." Along with family tradition, matters of the heart and practicality can all play a role in owning and maintaining a second home. For me, all three have come into play.

In the 1960s, my Grandmother moved to Sedona, Arizona, and my family has been going there ever since. When Gram passed, my Dad, Uncle, brother, and I bought Gram's home—a decidedly not fancy but cozy builder house in which we host family reunions, regularly vacation, and rent out on occasion.

Thus far, our primary sustainability initiatives have been the absolute basics: turning down or off all systems (heat, hot water, appliances) when the house is unoccupied; incorporating native plantings attractive to pollinators, and encouraging the growth of native grasses; hanging wet laundry outside instead of using the dryer; recycling and composting. Converting to solar is an ongoing discussion.

Soon, perhaps, as I’m considering the snowbird lifestyle soon, maybe even this winter: Meaning, get out of The North for several months for the more temperate climate of the Southwest. How, then, can we—second home buyers and owners of vacation or holiday homes—lessen our environmental impact?

Sustainable Building Strategies

Whether building new or remodeling a second home, sustainable strategies can be easily incorporated to make the home more energy-efficient or even net-zero. That net or carbon zero home might be a tiny cabin in the woods or a contemporary ski chalet in the mountains. Either way, net-zero homes are designed with two main functions in mind.

First, they are almost entirely airtight, meaning super-insulated and with windows placed on the north and south sides to maximize the home’s ability to absorb the sun’s heat in the winter and minimize it in the summer. Ground source heat pumps are often incorporated into these homes to utilize the earth’s relative temperature to heat and cool the home. All of these design choices work together to achieve maximum energy efficiency. Incorporating a solar-powered system to run a completely electric home—as well as your hybrid or electric vehicle—is a wise, sustainable choice.
