Sustainable Learning Online: UNESCO's Young Masters Programme

In 2011 UNESCO inaugurated a global online education programme for 16–18 year-old students to learn about sustainability issues and solutions. The Young Masters Programme (YMP) is a free global web-based education and learning network about sustainable development. The programme is open for secondary students and their teachers from all over the world.

Extensive on-line teaching material gives the students a thorough understanding of sustainability issues and preventive environmental strategies. The students can also put their knowledge into practical use by starting sustainability projects in their local community.

Da Vinci Arts Middle School in Portland

The da Vinci Arts Middle School in Portland Oregon has the first and only LEED-platinum and net zero energy use classroom in America. LEED-plantinum is the U.S. Green Building Council’s highest rating for energy efficiency. A zero energy building (ZEB) or net zero energy building is a general term applied to buildings with zero net energy consumption and zero annual carbon emissions.

The 1,500-square foot music classroom and studio was constructed from plans developed by architecture firm SRG Partnership and the University of Oregon’s Energy Studies in Buildings Lab. The school's features include a passive temperature control system and solar roof tiles. These and other green features yield an efficiency improvement of 70 percent over Oregon building code requirements.

Gutters capture rain for landscape irrigation and use as greywater inside the building. The school's experimental natural lighting system called “the Halo” provides adequate light, even with overcast skies, making additional light sources entirely unnecessary during the day. The sun’s rays pass through a diffuser which spreads the light evenly throughout the room. After dark, by amplifying and dispersing small amounts of electric light, the diffuser requires only half the energy normally required by traditional classroom lighting.

The da Vinci school teaches sustainability by example and it seems to be infectious. Even in their extra-curricular activities, students at the school show their loyalty to green. A project by da Vinci's after school class, Community Evolution / Garden Revolution, built a greenhouse for the residents of Dignity Village. See their blog for details.

The da Vinci addition is only the beginning, every public school building in Portland will be subject to rebuilding or remodeling over the next 20 years. An assessment of the performance of the various green featurs of the da Vinici school will help determine which sustainable features will be integrated into future classrooms.

The Future of Green School Buildings

The greening of schools is leading the green building trend. With large numbers of public schools deteriorating, boards across the US are taking a serious look at new green schools and retrofits that save energy as well as improve learning.

In the US, Federal incentives are already helping boards to green their schools. Under the American Recovery and Reinvestment Act’s fiscal stabilization fund, $48.6 billion was awarded to the US Department of Education. The construction, renovation and repair of green school buildings qualify for these government funds.

In the future all levels of government as well as new building codes will contribute to even greener schools. The next generation of green schools can be expected to do an even better job of controlling temperature, air, light and noise.

Each classroom will have independent climate controls and the ability to independently deliver fresh-air. Part of delivering fresh air, involves the ability to open high and low windows that can quickly refresh a room without drafts. Green schools will also manage solar overheating with awnings and shades that do not eliminate light or obscure the view.

The next generation of green schools will also do a better job of managing traffic noise, room reverberation, and noise transmission between rooms.

New green schools will be designed with materials that are easy to clean. This is important because the cleanliness of surfaces directly contributes to indoor air quality. Materials used in desk and contact surfaces must be easily disinfected to help prevent the transmission of infectious diseases.

As early adopters of new innovations green schools will continue to improve their environmental, health and performance benefits.

Green School Buildings: The Many Benefits of Ventilation

The kind of ventilation we see in green schools, promotes wellness and supports a healthy learning environment.

Poor ventilation is often behind sick building syndrome, which is known to cause symptoms including eye, nose, and throat irritations; headaches; fatigue; difficulty breathing; itching; and dry, irritated skin.

The primary purpose of a building’s heating, ventilation, and air-conditioning (HVAC) system is to provide comfort for the occupants by meeting thermal requirements and diluting contaminants. HVAC systems accomplish this through the conditioning of outside air coming into occupied spaces and the removal of irritants and pollutants.

Green school guidelines typically address HVAC systems as they relate to energy efficiency, indoor air quality (ventilation), moisture control, filter efficiencies and maintenance, and the elimination of CFC-based refrigerants.

In a comprehensive review of the literature related to indoor air quality, ventilation, and health symptoms in schools, Daisey et al. (2003) found that a significant proportion of classrooms did not meet the minimum ventilation standards. A variety of volatile organic compounds (VOCs) and bioaerosols (primarily molds and fungi, dust mites, and animal antigens) could be found in school environments.

Reducing indoor pollutants, providing adequate quantities of outside air, and ensuring that the ventilation system is properly maintained have all been linked to reducing absenteeism, improving teacher productivity and student learning. In a 2006 study of 54 elementary schools, researchers identified a 14.4 percent improvement in standardized math test scores in classrooms with a ventilation rate that was double the norm.

Through moisture management, pollutant source control and adequate ventilation rates, green schools have cleaner air and thus a healthier environment more conducive to learning.

Green School Buildings: The Many Benefits of Natural Lighting

The use of natural light in green schools benefits students, teachers and administrators. By reducing energy requirements, natural light also offers an environmentally friendly means of bettering the bottom line.

The sun provides higher light levels than traditional lighting while reducing energy costs. Natural light affords excellent illumination of educational materials and this appears to improve test scores. A well known school-building study, completed by the Heschong Mahone Group, identifies test scores 7-26 percent higher for schoolchildren in classrooms with plentiful natural light than for those in classrooms with little or no daylight.

A study from Alberta Education, titled A Study into the Effects of Light on Children of Elementary School Age indicates that natural light does have a positive effect on health and on rates of achievement. Children in classrooms with a natural spectrum of light including trace amounts of UV radiation had 1.75 fewer cavities than children in schools with traditional lighting. Children exposed to high pressure sodium vapor lighting were absent 3.2 days per year more than students in classrooms with full spectrum light.

The Alberta Education study also linked scholastic achievement to natural lighting. Students exposed to high-pressure sodium vapor lighting demonstrated the poorest rate of academic achievement.

A Sacramento California study titled, Light Helps Pupils Learn, is one of the largest ever done on natural light in schools and it suggests children learn faster and do better on standardized tests in classrooms with more daylight. Learning rates were 26 percent higher in reading and 20 percent higher in math in rooms with more daylight.

Windows let in light and when opened they provide natural ventilation. Windows also provide visual access to the outdoors, from morning to night and season to season, this is important to our circadian rhythms and our sleep cycles.

Ideally natural light in a green school lets in light without glare, while preventing overheating and excessive UVs.

Cost efficiency, energy reductions, improved scholastic performance and health benefits make natural lighting a logical choice.
