Top Tips For Domestic Refurbishment, Joseph Little

Articles

1) It stands to reason that insulating a wall should not affect its strength or longevity, nor should it result in a buildup of moisture (inter-stitial condensation) or mould. However the Industry is currently gripped with a desire to insulate to the highest standard (U-value) at the lowest financial cost, as quickly as possible, with little thought of these issues. An appropriate, robust solution must take the original wall, the occupant’s health, the room’s function and even the building’s location into account.

New Code Changes Under The 2009 Ibc, John W. Lawson

Architectural Engineering

The evolution of building codes typically produce design provisions that are expected to create safer and more accurate designs. We as engineers expect building codes to advance the state of the art with each successive edition. The 2009 International Building Code (IBC) and the Building Code Requirements for Structural Concrete (ACI 318-08) have significant revisions affecting the design of tilt-up buildings, but in some cases not necessarily advancing the state of the art. For example, the latest ACI 318 edition is largely revising slender wall design back to match equations found in the old 1997 UBC. In addition, the latest …

Lessons Learned In Sustainable Information And Technology Transfer Considering Culture And Resources, Craig V. Baltimore

Architectural Engineering

In terms of information and technology transfer, sustainability is defined as the ability for a society (or culture) to maintain and incorporate the information and technology in a long term manner without continued outside influence. When a major disaster occurs, like the recent Haiti earthquake, the good intentioned outside relief effort is often immediate with no lasting effects. For example, to have a new building built out of precast panels engineered and manufactured in the U.S., and erected with volunteers from outside of Haiti, will immediately provide for the local community. But will have the people learned in terms of …
