Achieving Sustainability Through Multiple Systems

Creating a sustainable city depends on optimizing multiple systems. It doesn’t happen with tackling just one issue.

Here’s a BuildingGreen post from Alex at BuildingGreen.com about “Europe’s greenest city.” Växjö, pop. 61,000, set a goal to be independent of fossil fuels by 2030. The city has addressed energy needs and pollution with several approaches.

A biomass combined heat and power plant burns wood chips sourced locally. The plant serves 6,500 customers with heat delivered via insulated hot-water pipes, and provides electricity to 29,000 customers. The city’s population is roughly 61,000 people. More in the Wikipedia entry.

This all reminds me of what  CCLEP is doing on Minnesota’s north shore. With projects devoted to wind, solar, district heating, transportation, and energy efficiency, CCLEP is figuring out what works. It often takes a hefty investment in infrastructure up front, but the effort should pay off over time, and pollution should be more easily minimized.

Small Iowa Town Cuts Energy Use By 8% In One Year

Fairfield, Iowa cut energy use.

Fairfield, Iowa, cut energy use by 8.5%.

According to Midwest Energy News, the town of Fairfield, Iowa, has cut its energy use by about 8% in the last nine months. How did they do it? Primarily through simple conservation measures such as switching to compact fluorescent bulbs and air sealing. The low-hanging fruit is easy and is pretty much free money.

Becoming A Very Green City

Convergence. Synergy. Whatever you call it, many different organizations in my city (the La Crosse, Wisconsin area) are coming together to learn, teach, and practice sustainable living principles. And it appears that momentum is building. La Crosse is becoming a very green city.

So many different projects are interwoven that it can be challenging to remember them all. Some are well under way, such as Gundersen Lutheran’s projects, and some are still in the planning stages. In no particular order…

Creating a community food system

Hillview Urban Agriculture Center is building a community food system. This nonprofit group is working with Western Technical College, Mayo Health System, Organic Valley, the YMCA, and others to grow and distribute food for local people to eat, addressing food insecurity, food deserts, and healthy eating.

Western Technical College will build a new greenhouse system on campus that will provide space for Hillview, as well as for the college’s Landscape Horticulture Program. The college will build three Passive Houses on the former Hillview Greenhouse site. WTC students will help build one home per year, gaining invaluable hands-on experience, integrating the different elements of the Building Innovations program, and adding to knowledge of best practices for sustainable housing. The houses will be sold, adding to the tax base of the city.

This photo shows the old Hillview site, where three Passive Houses will be built by professional contractors and WTC students.

 

Western Sustainability Institute will be a regional resource

WTC is also building the Western Sustainability Institute, which is to be a central resource for the regional sustainability efforts of business, government, nonprofits, and education. The Sustainability Institute will be advised by the Mississippi River Region Sustainable Communities Consortium (MRRSCC), which includes members from regional government, planning, education, and nonprofit entities. The MRRSCC is being developed with funding from a grant from the Department of Housing and Urban Development (HUD).

Gundersen Lutheran is nearly energy independent

Gundersen Lutheran Medical Center is a national leader in sustainability efforts through their Envision program, and will be energy independent in 2014. They’ve invested in conservation, tapped the county landfill for methane, invested in wind farms, installed a biomass boiler, and more.

And the City of La Crosse and La Crosse County have adopted The Natural Step, which provides a framework for ensuring that human activities are done sustainably. And many more projects are under way.
