More American cities are passing green mandates – laws requiring builders to adhere to environmental standards.

(NewsUSA) – When Washington, D.C. passed its Green Building Act of 2006, a mandate stating that all new private real estate developments need to follow the LEED (Leader in Energy and Environmental Design) standards set by the United States Green Building Council (USGBC), it broke new ground. Building green became the new industry norm.

When builders “go green,” they erect efficient buildings that use fewer resources, improve indoor air health and minimize environmental impact. Cities have embraced green building to save energy, water and waste-management costs. From 2003 to 2007, the American cities with green building mandates grew from 22 to 92, a 418 percent increase.

How do buildings go green? The LEED system certifies buildings as silver, gold or platinum. Platinum buildings most closely follow the USGBC’s environmental standards, which look at location, water conservation, energy consumption, atmosphere, materials, indoor health quality, innovation and design.

A truly green building relies on a marriage between eco-friendly consumer products, like low-flow faucets, and renewable energy sources. Architects know to begin with sustainable building blocks -; choosing strong, energy-efficient building material can help ventilation and heating and cooling systems use less energy while improving indoor air quality.

For example, one company, Alternative Construction Technologies, Inc. (ACTech), has developed insulated structural panels made from 75 percent recycled materials. In tests, the ACTech panel system proves up to 65 percent more energy-efficient than traditional building materials. Buildings constructed using the system will waste less energy, so renewable energies, like wind and solar power, can be incorporated to optimize their intended economies and efficiencies.

The panels improve indoor air quality and acoustics. They are also firesafe and able to withstand hurricane-force winds, making them a safe building material in natural disaster-prone areas.

As American cities look to improve their carbon footprint, they must combine green materials with eco-friendly energy sources. Fourteen percent of U.S. cities with populations over 50,000 already have green building mandates, while another 36 cities plan to enact them.

Companies must develop ways to use water – a renewable resource – without harming the planet.

(NewsUSA) – The saying, “Water, water everywhere, but not a drop to drink” rings true. Although water covers 70 percent of the Earth’s surface, humans make little use of its potential.

Fresh water irrigates fields, washes dishes and prevents dehydration, but it only accounts for 1 percent of the water supply. Moving water provides energy, but only 19 percent of the world’s power comes from hydroelectricity.

Water’s a natural, renewable resource, but humans don’t always use it in eco-friendly ways. People must remove the salt from ocean water before they can drink it, but according to the National Research Council, ocean-desalination plants consume so much energy that they do Earth more harm than good.

Today’s hydroelectric technologies use dams to harness moving water’s energy. Large dams require energy and materials for construction, displace communities and destroy wildlife habitats. In the U.S., 80,000 dams divert and block moving water, changing river habitats into lakes and disrupting wildlife. In 2008, horrified fishermen saw the biggest Chinook salmon run in the Sacramento River collapse, partly due to a diversion dam.

But one Hungarian-based technology company, Power of the Dream Ventures, Inc., is working to improve the ways that humans use water. Its ocean desalination prototype, when completed, will use solar or wind power to produce drinkable water at low monetary and environmental costs.

Power of the Dreams Ventures, Inc. also built a model for a product called RiverPower, which can supply hydroelectric power without dams. RiverPower generators would be submerged at strategic points, using an entire river’s flow to generate electricity. RiverPower would supply energy 24 hours a day, making it more reliable than solar or wind energy.
