Learn the basics on home generators, from selecting the right one for your home, to installation, to routine maintenance.

A growing number of people have become aware of and even begun to measure their personal, ecological footprint on the planet. Others are concerned about healthy living and working spaces free of toxins. Some people simply see greening their properties as an effective cost-cutting measure or wise investment.

Brain-storming about urban revitalization commonly results in a myriad of creative proposals, from cultural centers and renovation projects to expansive parks. Rarely does this type of planning involve a futuristic complex of massive proportions within the city itself.

However, Valencia’s homegrown architectural prodigy, Santiago Calatrava, has managed to achieve something that can only be classified as architectural glory – The City of Arts and Sciences (Ciudad de las Artes y las Ciencias).

As the need for alternative and clean sources of power grows, we're investigating the possibilities. Here are 11 of the latest advances in wind power technology.

Reduce, reuse, recycle. This is the simplest mantra of the environmental movement and the guiding principle for families and small programs across the nation. How does this principle apply to infrastructure, specifically asphalt pavement? We already use as little asphalt pavement as we can, but this is more an economic decision. We recycle asphalt pavement to build new pavement. We reuse it as clean fill. What else can we do with it? Can we use it to collect solar energy?

perFORM[D]ance House

Teams participating in the 2011 Solar Decathlon strive to create high-tech, low-energy houses, but one team has created a home that also "dances." Florida International University's perFORM[D]ance House features movable facades that allow it to adapt to the needs of its occupants and environmental conditions. This flexible concept fosters connections between indoors and outdoors while mitigating Florida's hot, humid, and hurricane-prone climate.

Although developers are often regarded by architects as roadblocks to the creative process, Robert Wennett has set himself apart from this stereotype. Not your typical developer by any stretch, Wennett purchased property on Lincoln Road in Miami Beach and engaged Herzog & de Meuron to create what is surely the most amazing parking garage you’ve ever seen.

Living Building status was recently awarded to the Energy Lab on the campus of The Hawaii Preparatory Academy (HPA), a K–12 school on Hawaii’s main island. It is only the third project in the world to meet Living Building criteria.

After a bicycle accident left her paralyzed 12 years ago, Rosemarie Rossetti realized that the two-story home she shared with her husband, Mark Leder, would never be able to fully accommodate her needs. Rossetti and Leder began to look into design options for a new home, and soon their personal project evolved into a mission to research, design, and build a home that would serve as an educational resource for the building industry as well as for consumers. The product of their campaign is the Universal Design Living Laboratory (UDLL), a National Demonstration Home in Columbus, Ohio, that seeks to incorporate three different design movements: universal design, green building (targeting LEED for Homes certification), and healthful, chemical-free products.

Thermal imaging or infrared thermography is a nondestructive maintenance method that uses infrared cameras to measure the amount of thermal radiation emitted by objects, which is converted to temperature. Normally, to measure the temperature of objects near room temperature requires the detection of radiation in the infrared wavelength range (which is much longer than that of visible light, i.e., approximately 400–700 nanometers). Infrared images are normally colorized so that objects that emit more thermal radiation than others will appear as brighter colors (yellow, red, and white). Cooler objects appear in darker blue, purple, or green colors. Although thermal imaging normally detects only surface temperatures, infrared signatures often indicate temperatures inside structures.

Solar Decathlon homes typically focus on the obvious – using energy from the sun. Students of the University of Maryland chose instead to highlight another precious resource often taken for granted: water. Their design, titled WaterShed, was inspired by the Chesapeake Bay watershed, the largest estuary in the United States with an area of 64,000 square miles spanning the states of Maryland, Delaware, New York, Pennsylvania, Virginia, and West Virginia. Suburban sprawl combined with the lack of stormwater management has threatened these natural ecosystems. WaterShed offers a sustainable model for living in the area, incorporating a range of water features and living elements. Leah Davies, who serves as one of the team leaders, explains that the home "mimics the cyclical nature of the Chesapeake Bay ecosystem by demonstrating the hydrologic cycle on a micro-scale."

Interested in lowering water resource costs, wastewater costs, and being able to use water during periods of restricted use? If so, consider installing a greywater system. Greywater systems are plumbing systems that recycle wastewater collected from washing fixtures such as showers, tubs, and sinks. The wastewater is filtered so that it is able to be used in non-potable (i.e., do not drink it!) applications such as irrigation and flushing a toilet.
