By Klaus Reichardt

ADMITTEDLY, URINALS ARE NOT an everyday topic of conversation. And when it comes to homes and apartments, they almost never enter the discussion. However, that may be changing and changing very soon.

Home urinals, ranging in popularity, have been found in parts of Asia, Europe, Australia, and even in India. However, the trend in the United States is still in its infancy. In addition, the economy, which has severely impacted the housing construction industry, has slowed things down considerably.

Housewrap: What's the Difference?

IT'S A CONUNDRUM: How do you prevent water from entering a building, while also allowing any moisture that does make its way in to escape? This is the formidable task given to housewraps, and increasingly to roof underlayments. Housewrap, a common type of weather-resistive barrier (WRB), is installed between the cladding layer and the sheathing, while roofing underlayments go directly under shingles or other roofing material, forming a second line of defense against the elements.

What’s the best way to ventilate a single-family dwelling? Experts take a look at new vs. existing construction, and evaluate the risks and solutions associated with ventilation in hot-humid climates.

WHILE VENTILATION IS IMPORTANT to maintain good IAQ, introduction of outside air—whether through natural or mechanical means—can have profound impacts on energy use and indoor humidity levels, particularly in humid climates.

Optimizing Multifamily Buildings

Multifamily buildings are very different from single-family homes. They include central HVAC systems, shared walls, shared spaces, and so on. What are the best ways to improve their energy efficiency and overall performance?

THE ENVELOPES OF MULTIFAMILY BUILDINGS typically account for a smaller share of the structure’s total energy use than the walls and roof of a single-family structure. Expensive to retrofit, they often have central heating and hot water systems with large distribution inefficiencies. Therefore, heating control and distribution improvements often represent the best retrofit option for the cost. Accurately modeling and optimizing these measures, however, is challenging with the tools that exist today.

Duct Diligence

The majority of heating systems are forced air, and distribution problems often lie in duct design and integration. What new technologies and research can make these air distribution systems more efficient?

EFFICIENT AIR DISTRIBUTION is critical in the delivery of high performance homes. Innovations—simple and cost effective to implement—have been developed and tested throughout the country. But the application of these strategies continues to be a challenge—especially ones that address less-than-optimal situations—such as flex duct and splitter box air distribution systems and ducts in unconditioned spaces. More focus needs to be put on dealing with these scenarios.
