There are 26 million homes in the United Kingdom. Together they contribute 27% of the UK's carbon emissions, making the housing sector a vital part of the goverment's committment to an 80% reduction in carbon emissions by 2050.

Since 2007, the award-winning SuperHomes network has promoted the benefits of eco refurbishment using free Open Days. Pioneering owners of some of the UK’s most energy efficient homes host free tours and Q&A’s each September. SuperHomes are older homes that have been refurbished for greater comfort, lower bills and at least 60% fewer carbon emissions.

Currently there are over 180 registered SuperHomes in the UK and over 70,000 people have visited one. The aim is to inspire visitors to take action to green their own homes, by providing actionable ideas, such as improving insulation, installing alternative heating sources or producing their own renewable energy. The network hopes to register 500 SuperHomes by 2020 and attract 2 million visitors.

It is estimated that as many as 80% of all UK homes that will be in standing in 2050 have already been built. Of particular concern are the 7 million solid wall properties, most of which are difficult to heat. To meet its target of an 80% reduction in carbon emissions by 2050, the UK should be refurbishing 600,000 homes a year. At the current rate of change it will take over 500 years to refurbish these homes.

Jurgen Huber, who recently joined the network says:

"My house is now 100% carbon neutral. Along with my wife and two children, we use and generate 3300 kWh of electricity. We have no gas connection so we cook with the most energy efficient induction cooker, we heat water with an electric instantaneous water heater, and we heat rooms with a highly air source heat pump and electric underfloor heating. This is only possible because we insulated the house to a very high standard."

Huber explains that the first phase of his home renovation was done on a budget of £4000. This paid for all insulation materials, the air source heat pump, an induction cooker, and LED lighting. The PV solar panels added afterwards cost £12,000 and were financed with a bank loan. In 8 years Huber may make a bit of money but that’s secondary. He wanted to prove that anyone can have a retrofitted energy neutral house on a tight budget.

"The result is that we’ve a very comfortable home that can be quickly heated or cooled at very little cost. At the same time we’ve maintained the 1920s period character of the property which is something we love."

Huber's testimonial is a good example of how the SuperHomes network harnesses the enthusiasm of pioneering households to demonstrate the benefits of switching to low energy living.

The network's open days help visitors gain the confidence to green their own homes. Free tours and Q&A sessions allow visitors to find out more about both the benefits and the challenges involved in refurbishing an older home.

There’s no question, the environmental and social challenges of the 21st century are complex. While design alone may not solve all of these issues, Big Future Group believes that many of the adverse effects of climate change can be mitigated by sustainable design. As designers, we hope to address not only the immediate physical effects of climate change on communities, but also provide a framework of practices that advances quality of life issues with minimal impact to respective ecosystems over time, with specific attention to sustainable practices that minimize human impact on water, land, energy consumption, and biodiversity. These sustainable building methodologies can help people adapt, and sometimes even benefit from the effects of extreme environmental conditions that have become the new normal.

While sustainable design remains at the forefront of climate related dialogue, Big Future Group approaches the conversation from a different perspective: a multi-disciplinary collaboration of research and expertise. The founders—Sharon Davis, Julie Farris, Arun Rimal, and Eric Rothstein—met while working on the design and construction of an award-winning Women’s Opportunity Center in Kayonza, Rwanda. Together, they represent fields of architecture, engineering, hydrology and landscape architecture, to collectively explore multi-faceted solutions to food shortages, flood/drought, deforestation, unavailable access to energy, poor sanitation and health conditions, and an increasing carbon output.

Their work in Rwanda is a good example of the work they’ll be doing moving forward. The project, sponsored by Women for Women International, is made up of 20,000 sq ft of space covered by roofs that serve to shade and shelter women, and simultaneously harvest rainwater with durable cisterns. Rwandan women living in the area handcrafted a half-million bricks on site in order to build classrooms, which are made up of curved walls that create intimate communal spaces. The project also incorporates a landscape designed to nourish the community, a communal kitchen, lodging, and a marketplace to sell goods made there. While working together on this transformative project, the four decided that the Women’s Opportunity Center project was just the beginning, and that more work was to be done. In June of 2011, they founded Big Future Group.

Utilizing innovation-generating design methodologies, Big Future Group will develop achievable goals for specific community-based projects, and multi-disciplinary teams will research, design, and build sustainable infrastructure for areas in need. Big Future Group’s projects are focused on scalable, replicable and transferable measures, as these practices are essential to sustainability and viability.  The projects also aim to serve each community’s unique site conditions, values and communal needs, which can often lead to unexpected opportunities for innovation, essential for future progress.

In a recent story written by Ashley Halligan, an analyst at Software Advice, she gave recognition to four global urban sustainability initiatives that are lesser known in terms of environmental innovation. Some are lesser known because of being historically volatile--whether in terms of violence or excess waste--or, perhaps, being nonexistent altogether.

In an article outlining the initiatives of Medellin, Colombia; Naples, Italy; Philadelphia, Pennsylvania; and, Songdo, South Korea, Halligan outlines vastly different approaches to creating environmental sustainability goals and becoming global leaders for these initiatives.

Medellin, for example, has a violent history. Once being deemed the most violent city in the world, it's now a 2012 awardee of the Sustainable Transport Award, alongside long-respected San Francisco.

Naples, on the other hand, has been infamous for its devastating trash crisis, with alleys, parks, and squares literally piled with waste--mostly linked to the local Camorra (mafia-like organization). Residents have taken matters into their own hands hosting guerrilla gardening groups and flash-mob clean-ups.

Philadelphia, a U.S. city not particularly known for its environmental forwardness, vowed in 2008 to become the country's "greenest" city when Mayor Mike Nutter gave his inaugural speech. With a six-year, 14-initiative project underway, Philadelphia shows that any city can overcome current challenges.

Lastly, Songdo, represents an entirely different approach to sustainability. A city built from scratch atop South Korean swampland, Songdo is the country's first Leadership in Energy and Environmental Design (LEED) Neighbhorhood--all of its buildings also either meet or exceed LEED standards.
