800-1500 Words

Response Location: France, Paris

In Paris, about 7,500 buildings are heated using geothermal energy, a cost-saving and carbon neutral energy source. Water is drawn from deep below ground at a central location and heated by the earth, and then sent via underground pipes to individual buildings. The Bagneux and Chatillon district has scaled up the system, providing heat to over 40,000 people. Districts created joint ventures to reduce construction costs and residents do not notice the energy source shift because when the temperature drops to a point where geothermal energy is not viable, gas boilers automatically keeps the heat flowing.

With rising temperatures occurring all over the world, cities are implementing plans to combat heat waves and protect its residents. The city of Ahmedabad in India has been a model for heat resiliency after it created its first heat action plan that centered around “community-focused social measures.” Because of the plan, a 2015 heat wave resulted in fewer than 20 fatalities compared with thousands of deaths in previous years. Other cities like New York City are also participating in heat resiliency efforts aimed at protecting all of its residents.

Response Location: United States, Red Lake Indian Reservation, Minnesota

The Red Lake Nation in Minnesota is building a 240-kilowatt solar array on top of a workforce training center, which will generate about half of the building’s electricity. This project was financed through crowdfunding, where they raised $250,000 from religiously inclined microlenders. The goal: to allow the tribe to have energy sovereignty, create higher-paying jobs, and maintain a healthy environment.

Response Location: Sweden

Urban planning using gamification is a viable way of engaging diverse parts of the population and placing people and communities at the center of the process. “Block by Block” is a collaboration between UN Habitat and the game company Mojang that holds participatory workshops, where people design public spaces using the game Minecraft. Over 25,000 people from diverse backgrounds and age groups have participated. Professional advisers are present and they adjust the designs for implementation. The method has been used by the City of Stockholm and to create the first skatepark in Kosovo.

Hempcrete is made from the dried core of hemp stalks and a lime-based binder and can be cast into blocks and panels just like concrete. But unlike concrete, which emits CO2, hempcrete actually absorbs it while also reducing construction waste. Though not strong enough to be load bearing, it has outperformed other materials in terms of insulation, and is therefore an ecofriendly option for covering walls. Reducing the need for air conditioners in warm climates limits CO2 emissions even more. Hempcrete has been used to build new structures and retrofit existing ones in Europe and Australia.

Response Location: Kenya

Gjenge Makers Ltd is an alternative building product manufacturing company that creates products – such as pavers and blocks – out of recycled plastics. Founded by four Kenyan engineers, the team began by studying the manufacturing process and researching what products would do well on the market. They then built all of the machinery themselves, which break down the plastics, and then mix them with other building material products to ultimately create customizable plastic bricks that can withstand larger weight and are less expensive than concrete. They are popular in rural and lower-income areas.

Response Location: United States, Spokane, Washington

Eastern Washington University recently built the first tall wood office building in the state joining hundreds of other large “mass-timber” projects in the United States. This growing industry constructs panels, beams, and columns from trees that need to be thinned to curb wildfires in forests. While wood buildings can be more expensive to build than ones constructed from concrete and steel, environmentalists are on board because wood can store carbon, which can help offset greenhouse gas emissions.

Response Location: Sweden, Stockholm

Harnessing body heat provides energy-saving heating to commercial and residential buildings. The Stockholm Central station in Sweden and the Mall of America in Minnesota both capture body warmth to provide some of the buildings' heat. Each has over 100,000 daily visitors during non-coronavirus times, generating substantial heat that can be captured by energy-efficient construction. Body heat is also utilized in residential spaces, where thermal insulation helps keep the warmth inside. Using body heat requires energy-efficient building materials and generally cannot provide all of a building's heating needs.

Response Location: South Korea, Seoul

There’s a subterranean, organic farm in one of Seoul’s subway stations that could be another way to approach sustainable urban farming. The “vertical” farm, known as Metro Farm, uses a mineral nutrient solution instead of regular soil, and has an automated tech network to control the underground ecosystem’s temperature, humidity, and carbon dioxide levels. While Farm8, the tech startup in charge of the venture, hasn’t made much of a profit yet, the farm produces about 30 kilograms of vegetables per day at a rate that is 40 times more efficient than traditional farming.

More and more commercial real estate projects are popping up around the United States that are focused on “deep green” building. This movement suggests that it’s not enough to just make a building out of renewable materials, but they can also be self-sustaining. For example, the Watershed, an office building in Seattle, has a slanted roof that collects rainwater that is then used in toilets. These types of projects can be more complicated and expensive to build, but developers can save money in the long run with the improvements.
