Energy codes and standards play a significant role in the United States construction market by influencing the design of commercial buildings. Once a code or standard is adopted by lawmakers, it becomes a legal requirement that protects our society from substandard building practices and ensures a minimum level of energy efficiency is achieved.

From the outside, the newly opened New World Center, the campus of the elite New World Symphony in Miami Beach, Fla., may not appear to be a celebration of curves.

In 2011, Bill Chaleff, of Chaleff & Rogers Architects, came to Community Environmental Center (CEC) with a challenging situation. Chaleff’s client, who owned a vintage mansion in Southampton, Long Island, wanted to repair the house and wanted a sustainable solution for insulating the exterior walls so that the original interior plaster faces of the walls could be preserved.

Building on a strong foundation has been a well-recognized principle of construction for thousands of years, but we still continue to violate the concept. One of the most violated areas of below-grade construction is the failure to include moisture management. Joseph Cubby said, “Learn the past. Decide the present. Build the future.”

Village Suites Oshawa is a 556-bed student residence built for the University Of Ontario Institute Of Technology, Canada’s fastest growing university. The building is currently being evaluated by the CaGBC for LEED Platinum certification and if successful, at 270,000 square feet will be one of the largest LEED Platinum certified buildings in Canada.

One of the key components of sustainable homes and buildings is a thermally efficient and dry building envelope that minimizes the leakage of air through the home. Air leaks in walls and attics decrease occupant comfort by permitting the entrance of cold or hot air, depending on the season.

As energy costs continue to fluctuate, homeowners are seeing the benefits of becoming more eco-savvy. One growing area of focus is weatherization. When you consider that up to 40 percent of a home’s energy loss can be attributed to air infiltration*-a combined with recent government incentives-it’s easy to see why.

Air leakage is the unplanned, unpredictable and unintentional airflow across the building enclosure. This makes air flow control important for several reasons: to avoid air transported moisture and moisture damage, to reduce energy losses and to ensure occupant comfort and health.

The renewed emphasis on energy conservation in building codes has led to increased awareness of the importance of controlling air leakage of buildings. One of the most effective ways to conserve energy is to provide an airtight building envelope.

Water testing is complicated and as a contractor, if you have never had to be subjected to it, you can count yourself lucky. Water testing has made exterior plaster and EIFS work anything but business as usual.
