A Good Foundation

Concrete Footer

As with all sound structures, a home needs a good foundation. We start our homes by digging trenches that will be constructed into footers. These trenches are strategically dug in configuration of the homes.

These trenches are then lined with wire and rebar to ensure the proper depth and strength of the concrete, which will soon be the homes base.

The concrete is poured into the trenches at precisely the right depth, using the rebar as a guide. This method has been tried and proven to promote strength and consistency for the footers, which will enable the entire home to be even, level and sound.

Arguably, the footers or base of a home is the most critical in the building process. Done properly, the footer or base will keep the home level for life. Footers constructed incorrectly will allow the home to sink, or sag in areas, thus causing structural damage and loosing the integrity of the building.

Housing Starts Regain Some Ground

Monday, December 28th, 2009

Nationwide housing production rose 8.9 percent to a seasonally adjusted annual rate of 574,000 units in November, according to figures released by the U.S. Commerce Department today. The gain represented a partial bounce-back from an exceptionally slow month for housing activity in October, and was largely attributed to a big increase on the multifamily side.

“The fact that both starts and permits for new housing production rose last month is a good sign that we’re headed in the right direction, albeit slowly, on the road to a housing recovery,” said Joe Robson, chairman of the National Association of Home Builders (NAHB) and a home builder from Tulsa, Okla. “That said, the November improvement was primarily on the multifamily side, and poor job markets and other economic factors are still keeping many potential buyers on the fence for the time being.”

“Home builders remain very cautious about starting new homes, and overall housing production is still down on a three-month average basis,” noted NAHB Chief Economist David Crowe. “Understandably, it will take some time for the newly extended and expanded home buyer tax credit to start boosting sales in individual markets – just as it did the last time such an incentive was enacted. However, the fact that permits increased in November is a hopeful indication that the desired impact of the tax credit on housing demand may be forthcoming early in 2010. In the meantime, credit for new housing production remains extremely difficult to come by, posing significant obstacles to builders with viable projects.”

Single-family housing starts made up some of the ground they lost in October, posting a modest 2.1 percent gain to a seasonally adjusted annual rate of 482,000 units in November. Meanwhile, multifamily starts rebounded from an all-time record low in the previous month with a 67.3 percent gain to a seasonally adjusted annual rate of 92,000 units in November.

Gains in housing production were registered across all regions of the country in November, with a 16.4 percent increase in the Northeast, a 3 percent gain in the Midwest, a 12.3 percent increase in the South and a nearly 2 percent gain in the West.

Permit issuance, which can be an indicator of future building activity, rose 6 percent in November to a seasonally adjusted annual rate of 584,000 units, its highest level in a year. Single-family permits rose 5.3 percent to 473,000 units, while multifamily permits rose 8.8 percent to 111,000 units.

Three out of four regions posted gains in housing permits for November, with a 4.7 percent increase reported in the Northeast, a 10.7 percent increase posted in the South, and a 2.7 percent gain registered in the West. The Midwest posted a 1.9 percent decline

Rocky Mountain Institute releases Green Footstep

Monday, December 21st, 2009

Rocky Mountain Institute has unveiled Green Footstep, a free online carbon calculator for reducing carbon emissions in building construction and retrofit projects. Other online carbon calculators don’t address multiple building emissions over the building lifetime, but the operating costs you are saving over time. Green Footstep shows you the saved carbon.

Green Footstep also shows designers how to comply with specific design goals such as LEED’s energy credits and the 2030 Challenge, the organization that has challenged designers to make all new buildings carbon neutral by 2030. Edward Mazria, founder and executive director of Architecture 2030, says, “Rocky Mountain Institute’s Green Footstep is an extremely valuable goal-setting and evaluation tool that will help building designers assess a project’s carbon emission impacts with regard to site, construction and operations. Because the 2030 Challenge is integrated into the program, this tool can also help designers in their efforts to meet or exceed the 2030 Challenge targets.”

Michael Bendewald, an analyst with RMI who developed the online version, called Green Footstep a “designer’s tool” that designers can use to make specific design decisions that reduce carbon emissions on residential and commercial new and retrofit building construction projects, from pre-design through occupancy.

It’s also an educational tool that helps users understand a building’s life cycle carbon footprint. “Since we all have bank accounts, allow me to use an accounting metaphor to explain Green Footstep’s way of showing a project’s carbon emissions,” Bendewald explains. “The native-state carbon storage of a site, including such things as standing timber and other vegetation that existed before development, is the amount of carbon the owner of the facility ‘owns.’ Any carbon emissions send the owner into a ‘carbon debt.’ In order for a project to be ‘carbon neutral,’ this debt must be paid off and the original amount of carbon – equal in magnitude to the native-state carbon storage – must be restored. Green Footstep allows designers to adjust design targets, such as building energy use intensity and incorporating more renewables that will get the building out of the carbon debt edging the building closer to carbon neutrality.”

Green Footstep’s web site provides case studies so users can explore how Green Footstep has allowed past projects to reach their carbon reduction goals. Users can also create a login that allows them to save and reload their own projects as they work on them.
