Contractor to Contractor: In this second of a two-part series, contractor-turned-homebuilder Fernando Pages Ruiz shares his knowledge on how to choose a mix, prep the site, and install porous pavement.

Although a blended, high-course aggregate/low-fines concrete (a concrete blend of Portland cement, 3/8" or pea gravel aggregate, and little to no sand) is a simple concept, the logistics of it are far from simple. For this highly porous concrete to provide a durable surface, conditions have to be almost perfect. The concrete requires an exact proportion of aggregates and water, special chemical admixtures, proper mixing during delivery, and expert placement. I recommend that if you decide to use pervious pavement in one of your projects, don’t do it yourself. Hire the very best paving contractor in your area and work with the largest and most sophisticated ready-mix supplier. Pervious pavement is not so much a concrete product as it is a paving system, including soil, sub-grade, and, of course, the mix.

Businesses that don't "go green" may suffer in unexpected ways. Learn how your business can benefit from taking a sustainable approach.

An interview with Tedd Benson on Open Building, an approach to building that embraces the changing needs of homeowners.

How do cities become more resilient in the face of severe weather events? As natural disasters impose increasing levels of risk, how city planners, architects, and builders manage that risk is of critical importance.

A new exhibition center in Belfast tells the story not only of the Titanic but of the long maritime history of this iconic city.

One hundred years after the RMS Titanic’s maiden voyage and tragic sinking, visitors of the Titanic Signature Project in Belfast, UK, will be able to delve deep into the story of the Titanic and Belfast’s rich ship-building history. The five-level, 12,000 sq. m. (129,166 sq. ft.) building features a glass-walled atrium, which leads visitors to various exhibits throughout the building. The lofty space with irregularly angled forms provides the perfect introduction for the displays that follow.

The summer heat waves are upon us, so we've come up with some simple and easy ways to stay cool.

Environmentally friendly. Eco-conscious. Green. These terms have become increasingly important for the building products industry. Yet, because no standard definition exists and regulations surrounding environmental claims continue to evolve, many industry leaders find themselves blazing new ground in the green realm. In an effort to capture a moment-in-time synopsis of where the industry stands on environmental practices and products, I asked representatives from various segments of the building products industry to respond to one seemingly simple question: “What does green mean to you?” One simple question yielded diverse and complex responses.

Love it or hate it, Marcel Breuer's granite-clad Whitney Museum of American Art has loomed over 75th Street and Madison Avenue in New York's Upper East Side for over 40 years. After repeated attempts to expand and add much needed gallery space, the Whitney has officially announced it is headed downtown. Renzo Piano designed a new building for the Whitney in the hip Meatpacking District adjacent to the High Line, an abandoned, elevated railway that has been converted into a highly publicized park.

American universities have committed to greening their campuses. Three institutions — the University of Michigan, the University of California, and University of Pennsylvania — share their experiences.

Whenever you flip a light switch or adjust a thermostat at the University of Michigan in Ann Arbor, you’re unwittingly interacting with Henry "Hank" Baier, or at least with his department. Baier, Associate Vice President for Campus Facilities and Operations, oversees a city-size infrastructure supporting 80,000 students, faculty, and staff on a 3,200 acre campus with 500 major buildings, including 150 health clinics, three hospitals, two golf courses, and “The Big House,” also known as Michigan Stadium, the largest sports arena in the United States. As Baier sees it, “Energy is the lifeblood of our competitive society.” And by extension, the lifeblood of the university. “Our energy consumption and environmental footprint has become more important at the University of Michigan, because it’s become more and more important to our students and faculty,” says Baier. It’s become more costly, too; Baier’s campus devours $155 million energy dollars every year, meaning the concept of sustainability has become a fiscal necessity as well as an environmental imperative.

Looking at INhome, short for "Indiana home," one wouldn’t assume that it is net zero or even necessarily green, if not for the solar panels mounted on its roof. It looks like a quintessential Midwestern home, and that is exactly what Purdue University students intended for their 2011 Solar Decathlon entry. Sarah Miller, the team’s Architecture and Design Manager, describes the look as “transitional style,” falling somewhere between modern and traditional. With an estimated cost of less than $250,000, INhome’s practical design will appeal not only to the Midwestern homebuyer, but also a national market.

Brownfields are properties that are contaminated with hazardous substances and pollutants that may complicate the properties’ expansion, redevelopment, or reuse. Despite this drawback, brownfield development appears to be increasing. According to the Green Building Market and Impact Report 2010 of the GreenBiz Group, LEED resulted in an estimated 8,800 acres of brownfield reclamation in 2010 vs. 4,800 acres in the previous year. Reclaimed brownfield acres are forecast to grow to over 17,000 acres and 27,000 acres by 2020 and 2030, respectively.

Located across the street from SANAA’s Glass Pavilion at the Toledo Museum of Art is Frank Gehry’s Center for the Visual Arts. Completed in 1993 to house the University of Toledo Department of Art as well as the Toledo Museum of Art's Reference Library, the four story, L-shaped fortress like building is a prime example of postmodern Deconstructivism.
