Find out how to optimize your lawn's potential with these tips on fertilizing, going organic, and more.

The sun is shining, the grass is growing, and you're ready to go outside and invest a few weekend hours in making your lawn more beautiful. However, conventional wisdom about spring lawn care may not tell the whole story. In fact, the pervasive notion that spring is the ideal season to begin lawn maintenance may have more to do with your own mood than it does with the growing cycle. What practical steps can you take right now, while you’re feeling inspired, to improve your lawn’s appearance?

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

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.

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).

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.

A single-family home conceived as a series of pavilions harmonizes with its site, while showcasing several art-meets-architecture pieces.

David Stark Wilson, AIA, is one of those rare architects who pursues passions beyond his profession. An avid mountaineer and photographer (his third monograph is soon to be hot-off-the-press), Stark Wilson’s love of nature is evident in his built work, particularly in his designs’ relationships with their sites and his subtle incorporation of texture and color. He founded the design/build firm WA Design in San Francisco’s Bay Area in the mid-1980s. Since then, the firm has completed a range of residential and commercial projects including the Saratoga Creek House, for which it simultaneously served as architect and contractor.

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.

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."

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.

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?

What makes for success as an interior contractor and what are the basics of staying in business? An experienced contractor takes a look at some of the misconceptions that plague the industry and brings the focus back to fundamentals that can help you understand the full value of your skill set.

Being in business in this economy means understanding the fundamentals of our industry and where it's going. As a small business owner I've seen my fair share of ups and downs. Usually most of the misunderstandings and problems can be solved by a little inquiry and a lot of listening.

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.
