The BS* + Beer Show: Communicating High-Performance Details

This episode of the BS* + Beer show features Steve Baczek, Armando Cobo, and Barry Price talking about how they communicate high-performance construction details. Steve shares his “slider” system, which he designed as a way to have illustrative conversations about drawing plans with builders and homeowners. He shows us a wall section and how it can be manipulated to represent different details, including the location of control layers. He tells us about the drawings he calls “a set of twins,” which make clear a contractor’s work scope, and explains how he manipulates and freezes layers of a drawing to isolate…


FAQ: Ducts in the Attic

My heating and air conditioning contractor wants to put the air handler as well as the ductwork in the attic, which we’re not planning on insulating. The ductwork will be insulated, but is this still a bad idea? In a word, yes, it’s a really bad idea to run ductwork through an unconditioned attic unless very specific precautions are taken. A variety of problems are possible. The practice is still fairly common in some parts of the country. But as building scientist Joseph Lstiburek puts it, “Where were the adults when this decision was made?” First, ducts are going to…


How to Spot Misleading Electric Heating Efficiency Claims

Sometimes companies that make products stretch the truth, embellish features, or rely on their potential customers’ ignorance of how things work. Shocking, I know. The world of electric heating has such companies. But if you’re looking for a device that will provide electric space heating for your house, it’s actually pretty simple to figure out the truth. Two methods to convert electricity to heat Electricity is a marvelously versatile way to move energy from one place to another. One of the most important things to understand about it, though, is that it’s not an energy source or fuel, like natural…


Wall Sleeves: The Accessory You Never Knew You Needed

The simplest and most common spot to install a ductless minisplit heat pump head is on an exterior wall. Once the head’s location has been established, a hole is drilled behind the unit for refrigerant pipes, communication wire, and drain hose. Typically, this hole is 2-1/2–3 in. in diameter and slopes slightly downward to the outside to ensure condensate will drain well. The communication wire is fed through the hole and attached to the unit. Then, as the ductless head is secured to the wall, the excess wire, refrigerant pipe stubs, and condensate hose are fed out through the hole.…


Cheaper Solar Power Will Help Low-Income Families

This post was written by Galen Barbose, Eric O’Shaughnessy, and Ryan Wiser of the Lawrence Berkeley National Laboratory. It was originally posted at The Conversation. Until recently, rooftop solar panels were a clean energy technology that only wealthy Americans could afford. But prices have dropped, thanks mostly to falling costs for hardware, as well as price declines for installation and other “soft” costs. Today hundreds of thousands of middle-class households across the U.S. are turning to solar power. But households with incomes below the median for their areas remain less likely to go solar. These low- and moderate-income households face…
