Just How Climate-Friendly Are Timber Buildings? It’s Complicated
February 12, 2024 —
Eric Roston - BloombergThis article is part of the Bloomberg Green series Timber Town, which looks at the global rise of timber as a low-carbon building material.
The number of people living in urban areas around the world
will swell by upwards of 2 billion over the next three decades. Many of those people will need new homes. But building those with conventional materials would unleash a gusher of carbon dioxide: Concrete, steel, glass and bricks for construction make up a combined
9% of global CO2 emissions, according to research by the United Nations Environment Program.
Enter engineered wood, a seemingly no-brainer solution.
Mass timber is not the typical lumber that has structured single-family houses in North America for decades. The wood components are strong enough to hold up an office tower or apartment block, and building with them is thought to emit much less CO2 than using standard materials. And since wood is about 50% carbon, the material itself even stores a little carbon, to boot.

Battle of Experts Cannot Be Decided on Summary Judgment
June 13, 2018 —
Tred R. Eyerly - Insurance Law HawaiiWhen two competing experts disagreed on the cause of the loss, the trial court erred in granting summary judgment to the insurer. Garcia v. Firs Community Ins. Co., Fla. App. LEXIS 4237 (Fla. Ct. App. March 28, 2018).
Garcia, the homeowner, discovered water damage in his home, allegedly due to a roof leak. Garcia notified his insurer, First Community Insurance Company. A forensic engineer, Ivette Acosta, was retained by First Community to inspect the property. After the inspection, coverage was denied.
The homeowner's policy covered direct loss to property only if the loss was a physical loss. Loss caused by ""rain snow, sleet, sand or dust to the interior of a building was excluded unless a covered peril first damaged the building causing an opening in a roof or wall and the rain, snow, sleet, sand or dust enters through this opening." Loss caused by wear and tear, marring, or deterioration was also excluded.

Deterioration Known To Insured Forecloses Collapse Coverage
January 28, 2019 —
Tred R. Eyerly - Insurance Law HawaiiThe insurer properly denied coverage for collapse of a building when the insured knew from an expert’s examination that the walls of his house were deteriorating. Jaimes v. Liberty Ins. Corp., 2018 U. S. Dust. LEXIS 198224 (D. Colo. Nov. 21, 2018).
The insured discovered a crack in the wall of his home. He hired Anchor Engineering to inspect. Anchor found a large bulge in the south wall. Several problems with deterioration were noted in the basement. The structure of the house was unstable and dangerous.
The insured filed a claim with his homeowners insurer, Liberty. The claim was denied because damage to the wall was the result of deterioration.
The south wall of the house later collapsed. The insured submitted a second claim. Liberty again denied the claim because the collapse was the result of deterioration of the wall. The insured sued.

Unintended Consequences of New Building Products and Services
April 19, 2022 —
David S. Jaffe – National Association of Home BuildersAs home builders throughout the United States are grappling with building material price surges, and shortages or delays for certain orders, many are exploring alternatives products to complete or start projects. For example, according to a recent article, some builders are constructing homes from natural materials such as rammed earth, adobe brick, and volcanic rock. In addition to being readily available on site there may be heating and cooling benefits due to the natural insulation provided by these materials. The article cautions, however, that using these alternative materials may come with added challenges such as higher costs due to a need for skilled labor, delays by home inspectors who may be unfamiliar with the techniques and methods of construction, and energy consultants who might have difficulty calculating the value of homes with these materials. See Home Builders Are Turning to Natural Materials to Get Around Supply Chain Problems; There are advantages to buying homes made with natural materials, but expect to pay a premium, Alanna Schubach, Mansion Global (March 25, 2022).
Another caution, not addressed in the article, however, but one that should be heeded by builders considering alternative materials, is the unintended consequences that might result from using alternative products, whether they are natural products or any others. The long-term effects of material use should not be ignored.
For instance, it has been reported that earthen materials are known to contain numerous organic substances and can also harbor mold. It was not too long ago that mold was a high liability issue for builders and property owners. Similarly, the use of rapidly renewable materials - products that can be produced naturally and quickly from nature - is a key component of green building. They are also cellulose or carbohydrate-based products and as such are typically optimal food sources for mold in the presence of moisture.
To avoid mold, it is important to understand the relationship between construction materials and their susceptibility to mold in the presence of moisture. “Buildings will never be designed, built, maintained, or utilized perfectly; and weather and natural disasters cannot be predicted. The one thing we can have complete control over, the materials within the building, should be selected wisely.” See Mold Susceptibility of Rapidly Renewable Building Materials Used in Wall Construction, AM Cooper, Master's thesis, Texas A&M University (2007) (Samples of wool, cork, straw, and cotton-- rapidly renewable materials used as exterior wall insulation products--were exposed to different moisture amounts in an encapsulated environment, representing the environment within a wall cavity when exposed to water from pipes, leaks, condensation and absorption, or from initial construction. The samples were monitored over time for mold growth).
Mold-related issues are just one example of the potential for unintended consequences from the use of alternative materials. Carefully reviewing building material choices in advance may help eliminate non-conforming building materials, returns and possibly disputes. NAHB has developed a guide,
Assessing Building Materials, for builders who may not have their own review process for gathering information from manufacturers and distributors when considering the selection of new building materials.
The guide is intended to arm members with the most important factor when evaluating new materials or products: information. Use the guide to step through the information collection process to make an informed decision on deploying new products or materials. The guide is not intended to be exhaustive or all-inclusive, but it will help builders ask the right questions and seek the most relevant information.

Los Angeles Seeks Speedier Way to Build New Affordable Homes
April 29, 2024 —
Patrick Sisson - BloombergArchitect Brian Lane calls it “1,000 ways to no.” That’s the wall of red tape that he and his colleagues at the Santa Monica-based firm Koning Eizenberg hit when they propose affordable housing projects around Los Angeles. Regulations and code enforcement lead to delays, which drive up costs, kill projects, and exacerbate Southern California’s stifling housing shortage.
But over the last year, builders say that this bureaucratic morass has eased somewhat, thanks to the mayoral order known as
Executive Directive 1.
Mayor Karen Bass signed ED 1 shortly after taking office in December 2022, at the site of an infamous project
that took more than a decade to be approved. The emergency declaration promised to open a new era, directing city departments involved in planning and decision-making to expedite 100% affordable projects, sidestepping codes and regulations that have long added delays and costs. Approvals that might otherwise have taken a year or more are now mandated to happen within a 60-day window, with building permits to be issued within five days.

CDJ’s #10 Topic of the Year: Transport Insurance Company v. Superior Court (2014) 222 Cal.App.4th 1216.
December 31, 2014 —
Beverley BevenFlorez-CDJ STAFFRichard H. Glucksman, Jon Turigliatto, and Kacey R. Riccomini of Chapman Glucksman Dean Roeb & Barger analyzed Transport and wrote, “The decision is an important tool for builders’ counsel because the builder’s reasonable expectations can alter the interpretation of ambiguous terms in policies issued to subcontractors. Essentially, the builder’s intent is relevant to the interpretation of policy terms because the subcontractor’s intent in requesting additional coverage depends on the agreement it made with the builder.”

Home-Rentals Wall Street Made Say Grow or Go: Real Estate
July 23, 2014 —
Heather Perlberg and John Gittelsohn – BloombergAlexander Philips joined the rush to buy foreclosed U.S. homes four years ago, spending $40 million on houses in California and Nevada to operate as rentals. Now his firm, Twinrock Partners LLC, is getting ready to sell.
“We didn’t want to be the last one standing when the music stopped,” Philips, 38, said in a telephone interview. “We view this as a trade, not as a business.”
The U.S. home-rental industry, transformed over the past two years by Wall Street-backed companies that were built on the rubble of the housing crash, is poised to be reshaped again as landlords like Philips get out. Corporate owners with limited capital or deadlines to repay investors are now selling houses in bulk, or one by one, after a 26 percent surge in prices from a March 2012 low. For bigger firms, swallowing smaller competitors is among the best opportunities for growth as they shift their focus to managing scattered properties.

A Performance-Based Energy Code in Seattle: Will It Save Existing Buildings?
August 11, 2011 —
Douglas Reiser, Builders Council BlogThe City of Seattle has one of the most stringent energy codes in the nation. Based upon the Washington State Energy Code (which has been embroiled in litigation over its high standards), the code demands a lot from commercial developers. But, does it prevent developers from saving Seattle?s classic and old buildings? Perhaps.
The general compliance procedure requires buildings to be examined during the permitting process. This means that buildings are examined before they begin operating. The procedure is not malleable and is applicable to all buildings, old and new, big and small.
The downside of this procedure is that it eliminates awarding compliance to those buildings exhibiting a number of passive features, such as siting, thermal mass, and renewable energy production. This problem has prevented a number of interesting and architecturally pleasing existing building retrofits from getting off the ground. The cost of complying with the current system can be 20% more, and it might prevent builders from preserving a building?s historical integrity.
