Community Builds Keep the Cold Air Out

Inspired by the Dutch concept of “Energiesprong,” or “energy jump,” a developer in France retrofitted a group of townhouses for social housing to be more environmentally friendly. They installed polyurethane facades to avoid heat loss and solar panels on the roof. Upgrading the units to be more green cost more than a conventional retrofit, but over time, energy bills were cut in half. These green retrofits are being implemented in towns around the world and could be a model for developers that want to reduce their carbon footprints.

In a collaborative effort between developers, power companies, and the government, a new apartment complex in Utah will be almost entirely powered by solar energy. The complex, developed by Wasatch Premier Communities, will work with Rocky Mountain Power to determine how to integrate such technology into the region’s electricity grid. This kind of development is gaining ground in Utah, and those in the industry hope to educate others of the benefits of going electric.

A small business in Puerto Morelos uses invasive seaweed that washes up on Mexico’s beaches to create construction blocks. The company, Sargassum, mixes the seaweed with organic materials, presses the mixture into block shapes, and lets them bake in the sun to harden. The owner sells some of the blocks and uses some to build affordable housing in his community.

A collaborative partnership among local and national organizations made it possible to install solar panels on 10 Greensboro homes for free. Because of this effort, many low-income families have seen a significant decrease in their energy bills and an increase in value of their homes. Although convincing people to install the panels was a challenge, organizers are now figuring out how to scale the initiative and make it sustainable in the longterm.

The city of River Falls in Wisconsin built the state’s first city-owned solar garden, taking steps to reduce their use of fossil fuels and encourage community members to go green. Now, all city buildings are 100 percent run on renewable energy and residents can sign up for a program allowing them to buy renewable energy. Getting people to take action can be difficult, but city officials say they found the right message to get its residents on board.

An apartment complex in Utah includes a solar battery in every apartment allowing the resident, power utility, and building developer to save costs for generating electricity. Through a unique partnership, the power systems can provide 12.6 megawatts of power for the building, which translates into residents saving up to 40 percent on the energy bills. This setup might not be easy to scale, but the developer plans to expand the model in other states.

Localized, distributed energy systems are popping up around California. As the larger electricity system becomes less reliable in the face of wildfires, more individuals are turning to microgrids and solar energy with help from organizations like Clean Coalition and Stone Edge Farm Microgrid. While still happening on a small scale, such energy systems may become more popular as its sustainability in a changing climate shows to be more resilient.

Mosques across Amman, Jordan are adorned with solar panels, resulting in some very energy efficient places of worship (along with many other buildings). The mosques now cover 100% of their energy needs and can even sell excess energy back to the national grid. The city is aiming to become carbon neutral by 2050, and in addition to recycling, environmental education, and solar water heaters, Amman is expanding their ecotourism industry to attract more environmentally conscious tourists.

After an earthquake devastated the town of Düzce, Turkey, residents banded together to create a housing cooperative and later Düzce Hope Studio, a group of pro-bono architects and engineers working to help rebuild the town. What makes the building team unique is that the design process included and valued residents’ voices. Yaşar Adanah, an urban researcher, states, “What’s happening in Düzce is a rare example of a holistic approach to housing that can be a model for other neighborhoods.”

Ashton Hayes- a small town in England- adopted a Carbon Neutrality mission, meaning they hoped to produce as much energy as they consumed. Over the past 10 years they have reduced their emissions by 40%, attributing their success to the resulting neighbourhood cohesion, dedication, and it being a public decision as opposed to one made or implemented by politicians.
