The news, opinion pages and blogs of LIBN have been filled with the challenges Long Island is facing, and it seems that the very best of what “Our Island” has to offer is at risk. While we share many of the problems faced by other communities, we have regional challenges that make our plight unique and in some ways more desperate. The Long Island Regional Planning Council is tackling these challenges and will ascertain how Long Island may achieve a sustainable future. If we are to be successful in solving these challenges, Long Islanders must be ready to embrace a future that preserves appealing aspects of our suburban life, recognizes our remarkable assets and creates a community based upon the principles of stewardship and sustainability.

Our distinction as the most highly taxed populace, with the highest energy costs in the continental United States and a lack of housing options to meet the needs of our changing population has resulted in an accelerated loss of our talented and educated work force, particularly our young people. The affordability problems of our young work force are shared by our seniors, a growing segment of Long Islanders. You have heard this before.

“Our Island” also faces an aging and inadequate infrastructure. We cannot build or revitalize our downtowns without adequate sewer capacity and treatment to protect our drinking water. We cannot alleviate our traffic congestion without better transportation and transit choices. The natural resources that attract us to the Island are stressed or even disappearing. Failure to address global climate change and reduce greenhouse gases could bring more unhealthy air and permanent flooding. Our ability to attract and retain quality businesses which employ highly skilled, highly paid workers must be strengthened. These challenges threaten our quality of life and our economic viability.

Acknowledging these challenges and problems as daunting, there is hope that we can still right the ship. The council, with core support from our counties and in collaboration with our towns, villages, cities and an array of stakeholders, is embarking upon a sustainability planning initiative to ensure that not only does Long Island remain an economic engine, but that our quality of life will be preserved and enhanced. Our “LI-2035 Regional Comprehensive Sustainability Plan” initiative will produce an integrated sustainability action plan. It will NOT merely be another study of existing deficient conditions or a vision devoid of a charted course of how and what to change.

Assisting the council is a team of talented planners, engineers, scientists, economists and sociologists headed by Arup, an internationally respected firm, supported by local firms and community-based organizations in conjunction with federal, state and local government. The work product will draw upon sustainability successes from around the world with specific application to Long Island.

First, we will identify and assess the challenges we face in economy, infrastructure, resources and land use. We then will establish goals; develop a series of sustainable strategies with metrics to assess their impact on meeting our challenges; and identify the necessary governmental actions and funding mechanisms required to implement the strategies to reach the goals. Second will be the integrated action plan providing the “how to” and “who needs to do what” to reach a condition of sustainability by the year 2035.

The council is supported in the development of this plan by a Leadership Advisory Cabinet comprised of Long Island leaders in business and industry, institutions, regional government, the community, the environment and nonprofits. The cabinet is co-chaired by Bob Catell and Pat Foye. Supporting the cabinet will be stakeholder resource groups acting as technical advisors in specific thematic areas. The experience and expertise of our cabinet and stakeholder resource groups as well as broad public outreach will ensure that the critical issues affecting Long Island will be addressed, practical solutions proposed, information generated widely disseminated and that the action plan will be implementable.

The critical challenges and associated problems we face are real and significant. It is up to all of us to seize the opportunity to create a sustainable future for “Our Island.”

 Anyone who has ever stepped barefoot onto blacktop pavement on a hot sunny day knows the phenomenon very well: Black surfaces absorb the sun's heat very efficiently, producing a toe-scorching surface. In the wintertime, that can be a good thing: A dark roof heats up in the sun and helps reduce your heating bill. But in summertime, it's definitely a bad thing: Your house gets even hotter, and your air conditioning has to work harder. In most places, the summertime penalty is greater than the wintertime gain, it turns out, so that's why many people, including U.S. Secretary of Energy Steven Chu, strongly advocate switching to white roofs.

It's no small matter. In fact, Chu says that turning all the world's roofs white would eliminate as much greenhouse gas emissions in 20 years as the whole world produces in a year. But some critics point out that in northern cities, the gain in summer could be outweighed by the loss in winter. The ideal situation, then, would be to get the advantage of white roofs when it's hot and black roofs when it's cold.

Now, there may be a way to have both. A team of recent MIT graduates has developed roof tiles that change color based on the temperature. The tiles become white when it's hot, allowing them to reflect away most of the sun's heat. When it's cold they turn black and absorb heat just when it's needed.

The team's lab measurements show that in their white state, the tiles reflect about 80 percent of the sunlight falling on them, while when black they reflect only about 30 percent. That means in their white state, they could save as much as 20 percent of present cooling costs, according to recent studies. Savings from the black state in winter have yet to be quantified.

The team, which the students call Thermeleon (rhymes with chameleon, because of its color-changing property), was one of the competitors in this year's Making and Designing Materials Engineering Contest (MADMEC), a competition for teams of MIT students (or 2009 graduates). Now in its third year, the contest this year was specifically devoted to projects aimed at improving energy efficiency through innovative uses of materials. The final showdown was held Wednesday night, and the Thermeleon team took first place, earning $5,000 in the process.

Nick Orf PhD ’09, a member of the Thermeleon team, explains that he and his teammates originally tried to develop a color-shifting roof tile using a system of mixed fluids, one dark and one light, whose density would change with temperature: the dark substance would float to the top when it was cold, and white would float when it was hot. But the system proved too complicated, and instead they hit on a simpler, less expensive method.

Now, they use a common commercial polymer (in one version, one that is commonly used in hair gels) in a water solution. That solution is encapsulated — between layers of glass and plastic in their original prototype, and between flexible plastic layers in their latest version — with a dark layer at the back.

When the temperature is below a certain level (which they can choose by varying the exact formulation), the polymer stays dissolved, and the black backing shows through, absorbing the sun's heat. But when the temperature climbs, the polymer condenses to form tiny droplets, whose small sizes scatter light and thus produce a white surface, reflecting the sun's heat.

They are now working on an even simpler version in which the polymer solution would be micro-encapsulated and the tiny capsules carried in a clear paint material that could be brushed or sprayed onto any existing surface. The tiny capsules would still have the color-changing property, but the surface could easily be applied over an existing black roof, much more inexpensively than installing new roofing material.

Although they have not yet made specific plans for forming a business to commercialize their concept, Orf says the team members are determined to pursue the project and develop it into a marketable product.

Because the materials are common and inexpensive, team members think the tiles could be manufactured at a price comparable to that of conventional roofing materials — although that won't be known for sure until they determine the exact materials and construction of their final version.

The biggest remaining question is over durability, and answering it will require spending some time to do accelerated testing by running the material through repeated hot-cold cycles.

Hashem Akbari, leader of the Heat Island Group at Lawrence Berkeley National Laboratory in California, is a long-time advocate of white roofs as an energy-saving measure. He says that some other groups, including a team at the University of Athens, have done research on the use of color-changing materials for roofs, but that in those tests, "the cost and durability has been a serious issue."

The Thermeleon team hopes to address those concerns. "It's got to stand up to very harsh conditions," Orf says. "Those sorts of tests would have to be done before we'll know if we have a viable product."
