A Crash Course in Roof Venting

When To Vent Your Roof and When Not To
Much information has been devoted to the subject of roof venting. So much, that it’s easy to become confused and to lose focus. So let’s start with something that might sound controversial, but really isn’t: a vented attic, where insulation is placed on an air-sealed attic floor, is one of the most under-appreciated building assemblies in all of building science. A vented attic works in hot climates, mixed climates, and cold climates. It works in the polar arctic and in humid rain forests.

The Basics of Land Use Planning

The Power to Plan
Local agencies derive their authority to shape their communities through planning and land use from the “police power.” The source of this power is both the federal and California constitutions. The police power is broad and elastic and entitles cities and counties to take actions to protect the public’s general health, safety, and welfare. However, in most cases local regulations may not conflict with overriding state law.
Local authority to regulate land use can expand to meet the changing conditions or priorities of society. Thus, actions that might not have been thought of as part of the general welfare a century ago (for example, curbing sprawl or promoting affordable housing) can fall within its purview today.

A Practical Guide to Fiber-Cement Siding

Picking the right siding for your house is a delicate balancing act between good looks, durability, maintenance, and affordability. With wood, vinyl, stone, brick, or stucco, you might get only two or three of these. But with fiber cement, a resilient mix of wood pulp and portland cement, you get all four. It’s the only siding that combines the performance of masonry—minimal upkeep; rot-, fire-, and termite-proof; unaffected by wind or cold—with the look of painted wood clapboards, shingles, even stone or brick. Yet fiber cement goes for just a fraction of the cost of these other materials. No wonder nearly 15 percent of new homes—and many TOH TV projects—are clad with the stuff.
All this has happened in just 25 years, since fiber cement was first introduced. Now architects regularly specify the siding because it holds down costs without compromising aesthetics. It’s even accepted for use in many historic districts. Continue reading
